AMDOverdriveCtrl and multiple cards/profiles
Having multiple different manufacturer/model video cards in my mining rigs and trying to change the core/mem clock settings using AMDOverdriveCtrl I've come upon perhaps unintended behaviour. If you try to make different profiles to use with "AMDOverdriveCtrl -i X profilename.ovdr" you may inadvertently pull profiles of the card you first ran AMDOverdriveCtrl.
This caused me some headaches with trying to automatically set the memory clock to 300 at startup on my newest card. So, I tried starting from a clean slate on all the cards in the rig, but noticed some non-matching voltage settings on the info and overdrive tabs.
Ultimately I went on a renaming/deleting spree and solved the issues. Start by making sure AMDOverdriveCtrl doesn't run at startup, comment out the lines of your various startup scripts, then restart the rig. The following command lines are run from ~/.AMDOverdriveCtrl
1. Backup the following if you'd like, by doing this:
mv Current_Startup.ovdr Current_Startup.ovdr.old
mv default.ovdr default.ovdr.old
mv VeryFirstStart.ovdr VeryFirstStart.ovdr.old
2. Run AMDOverdriveCtrl for the card you want to create a profile for and save the profile:
AMDOverdriveCtrl [-i {3,6,9,etc.}]
3. Remove the Current_Startup.ovdr and VeryFirstStart.ovdr created in the process:
rm Current_Startup.ovdr
rm VeryFirstStart.ovdr
Repeat steps 2 and 3 for each card you'd like a specific profile for and you have accurate base settings to work with for all your profiles.

Anonymous banking and Bitcoin exchanges?
Bitcoin is anonymous as long as it stays in the digital realm. As soon as we try to convert it into the physical world, we lose a good part (if not all) of that anonymity. Does anyone know of a bank anywhere that doesn't require any hard ID requirements? One where one could open an anonymous account?

If someone withdraw money from an ATM with a credit card
| If someone withdraw money from an ATM with a credit card. Can there be a charge back ? If so, who end up losing the cash... visa or the back ? If there is no charge back possible, then maybe we have way to actually pay for bitcoin directy with a credit card.... you would have to pay interest since it's a cash advance but still would be more user friendly than the current way of doing thing. |
| It can't be chargebacked unless you claim fraud. And it's a much longer process than some scumbag frat boy lying to PayPal and clicking a few buttons. The credit union who issued the Visa/Mastercard will invoke a police investigation and the scammer will be held criminally liable if he's found out to be lying (i.e. the card wasn't stolen, gave it to a friend who cashed it out, CCTV camera proves he was there withdrawing it etc.) Even then, you can't reverse cash. Once you send it in the mail, it's obviously gone for good. In fraud cases the credit union absorbs the risk. |

How is the current banking system working?
I'm trying to get more information about how the current banking system is working.
The cash cycle is somewhat easy to figure out. Merchants bring huge quantities of cash to their bank so their are credited on their account. Banks put that cash in their ATM so when you retrieve money, it is charged on your account.
The only remaining question is what if a bank has too much cash and the other not enough. Is there a market for cash? Or is everything regulated by the central bank?
But now about the bank themselves. The money on your account is only a virtual value in some computer. When you pay someone from the same bank, nothing really happens except an addition and a soustraction in an internal database. In theory, if 10 people have an account with 1000€ in a bank, this bank has 10,000€ (we will ignore loans and debts for now).
Now, what does happen when you send money to an account which is not in the same bank?
It looks like an ACH is used. From what I understand, an ACH is mainly a bank for bank. So each bank should have an account to an ACH.
Is that right?
Who is controlling the ACH?
How can a transfer between two ACH happens?
How could it be controlled that the bank have well the money they pretend to have?
I'm a complete n00b in that field and I'm really interested to know the answers.

New Difficulty - 57% Increase. 1 GH/s = .656 BTC
Mining just got a LOT less profitable.
1 GH/s used to bring in 1.146 BTC per day. Now it brings 0.656 BTC/day.
BTC are currently trading for $15.50.
So a guy with a 1GH/s rig went from making $17.76/day to making $10.16/day.
Both figures are gross profit, not net profit (after electricity taken out). I used Deepbit's estimator for these income figures; for proportional pools, multiply figures by 1.07. For proportional pools with 0% fee, multiply by 1.10.
Daily income for 5830's is now 0.167 BTC, or $2.60.

mpact on GFX manufacturers?
Not sure if it's the right board or if it's been already discussed, apologies if so, but:
with all the talk about top ATI cards being sold out throughout the western world, do you guys think that the card manufacturers actually take notice of bitcoin phenomenon, or is it not even a blip on ATI's and NVidia's radar?
How about manufacturers, like MSI, Saphire and others?
Do you think they are working on custom chips?
Do they realize that they have a interest on helping to keep BTC alive?
Precisely. The vast majority of all sold AMD/Nvidia graphics cards are low to midrange cards for OEM computers, such as Radeon 5450, GT 420, Radeon 5750, GTX 460 etc.
They are also used as dumping pits for excess VRAM chips, so you may see an absurd amount like 2GB of memory on a GT420 for OEM use. It's a very profitable business.
Consider that these 2 companies sell tens of millions of graphics cards per year. Bitcoin users buy maybe 20,000-30k GPU's top
(which is still optimistic, seeing as most people use their pre-bought rigs, and some still mine on CPU's, few people actually build farms).
Ok, miners tend to buy high end cards which is a plus for their bottom line.
But it's still a drop in the ocean for them to care. Gamers and Eyefinity users still buy the majority of those.

What's your reject/accept ratio
Not stale rate, but rejection rate, which you can calculate using the stat shows in your miner. My case, for example, [8053 Accepted] [119 Rejected], so the reject/accept ratio is 119/8053=1.47%.
I believe this is also pool related:
deepbit: about 0.6%
btcguild: about 1.5%
slush: will test next...

How to build your own power supply?
I am considering spending almost $1,000 on 3-4 gold rated PSUs.
Seems to me they are little more than transformers.
If I could purchase 4*$30 PSUs simply to run the motherboard/cpu power... could I note create a massive single 12 volt rail that distributes power to say 30-40 video cards via pcie connectors at once?
I guess it would really suck if THAT power supply broke down... but still - anybody tried it or similar?

How to set up secure bitcoin savings account in 14 easy steps
1 download and install TrueCrypt,
2 open dropbox account (or some other free backup account)
3 get a small empty USB drive, get a safe, safe deposit box in your bank, etc...
4 create a truecrypt disk with image stored on this USB drive so that all bitcoin files and datadir and
therefore wallet.dat are on this truecrypt disk and make a .bat or .sh file which starts bitcoin client from this USB drive.
5 make sure that you will NEVER forget the password for this truecrypt drive but it is still very strong (forgot the password = lost all the money)
6 close/dismount truecrypt disk
7 make a copy of truecrypt disk image to your system
8 put USB drive under the mattress, into your safe, into safe deposit box, in a bottle dug into a hole in your garden etc...
9 store image of truecrypt disk to dropbox/carbonate/etc
10 store image of truecrypt disk to your email gmail/hotmail/whatever,
11 send a copy of truecrypt disk to your friends who keep their emails forever etc...
12 test that your "savings account" works by sending some money to it, than downloading/restoring the truecrypt image, mounting it, running bitcoin client from there, letting it to catch up with the blockchain and verifying that transaction you sent while it was offline is in.
13 send money which you want to be safe in your "savings account" to it occasionally even while it is offline
14 every once in a while mount the truecrypt image to catch up on blockchain and verify that it works (this also help to ensure that you do not forget the password), than back it up again to all the usual places.
Every time before you type in your password(s) make sure that your system is secure, i.e. nobody is eavesdropping on you.
Some steps above are optional, use your judgement. Your mileage may vary.
Optionally consider using TrueCrypt hidden volume feature. It allows you to have two encrypted volumes, one password opens "fake" volume, another password opens hidden volume. Put some 'incriminating files' into the first volume. Something nasty, but not illegal, like gay pr0n (or maybe str8 pr0n for gay people). Alternatively put to this 'fake' volume a set of bitcoin files but with small amount of money in it. Put real bitcoin stuff to the hidden volume. This creates plausible deniability, which might be helpful when one is compelled to divulge a password by law or by a 'rubber hose cryptanalyst'. You will have to remember 2 passwords now, though. While under duress you give away (but not too easily) the 'fake' password.
For this 'plausible deniability' to work you also would need to ensure that money you send to your real savings account are not easily traceable back to you, while money sent to 'fake' savings account are.
The most difficult thing here is to reliably remember the password(s) forever, you should be able to remember it 20 years down the road, reliably, and it still should be very strong.
Consider creating 'bitcoin saving' accounts for your loved ones and put information needed to recover 'the inheritance' into your last will and testament.

P.S. Amnesia could be a very expensive illness in bitcoin land, take care. You've been warned!

Virus scanner for MAC
since we are all about security now, I wonder if you think it is necessary to install a anti virus scanner for Mac OSX and if so, which one you would recommend.
Intego VirusBarrier for Mac. When I bought my very first Intel macbook the only thing in the Apple store was the norton software but it didn't yet have a universal binary. McAfee had a mac antivirus software but they only sold it in packages of three.
I looked around and found a really good 3rd-party review for Intego. I've used them on my Macs for years.

Bitcoin exchanges => Arbitrage opportunities
I've traded at both Mt Gox and Britcoin. The volume at Britcoin is about 1% of that at Mt Gox. The arbitrage looks great in theory, but if you offer a trade at the market rate it can literally take hours to complete on Britcoin even if it is only for 5 BTC.
If you only want to do arbitrage with small amounts like .1 BTC then it should work. It might work out, but it's not as clear as it looks because of the tiny volume.Don't forget the currency exchange spread, and the forex risk you accept (if you sell for GBP and buy for USD, it might make you an initial profit, but not if the GBP drops in relation to the dollar).
A bit of arbitrage would make the market look more professional, and provide liquidity to other BTC-currency pairs. Expect the arbitrage windows to drop to pennies pretty soon.

How much does a bitcoin cost currently in usd?
The cost to mine bitcoins is based on how much they are worth. If bitcoins go up in value, more people will mine (because mining is profitable), thus difficulty will go up, thus the cost of mining will go up. The inverse happens if bitcoins go down in value. These effects balance out to cause mining to always cost the amount of bitcoins it produces.

Silk Road is peer-to-peer website where users sell drugs to one another using a form of payment called Bitcoin, which is not physical cash, but rather currency controlled by bitcoin holders' computers. The website claims to be 100% anonymous through a TOR connection, but this is speculative and some are disproving this theory.

Why I cant hold all these bitcoins?
Bitcoin is a digital currency created in 2009 by Satoshi Nakamoto. The name also refers both to the open source software he designed to make use of the currency and to the peer-to-peer network formed by running that software. As opposed to conventional fiat currency, Bitcoin has no centralized issuing authority.

p2pool - Decentralized, Absolutely DoS-Proof, Pool Hopping-Proof Pool
P2Pool is a decentralized pool that works by creating a P2P network of miner nodes. These nodes work on a chain of shares similar to Bitcoin's blockchain. Each node works on a block that includes payouts to the previous shares' owners and the node itself. There is no central point of failure, making it DoS resistant.
P2Pool started as a project of mine with the intent of being completely decentralized, but I realized that some small centralization is required in order to prevent pool hopping without discarding coins.
When a node generates a hash that matches the share-difficulty level, it shares it with all the other nodes in the P2P network. When it generates a hash that matches the block-difficulty level, it pushes it to its local Bitcoin client, and also forwards it to the other nodes, which each push it to their client, maximizing the chance that the block will be accepted.
The difficulty for shares is a fixed fraction of the block difficulty - currently 1/600. This means that there will be an average of 600 attempts in every sharechain before a block is found. In order for the pool to be pool hopping-proof, direct payouts are paid only to the last 600 shares before and including the share that solved the block. This makes the expected value of joining at any time constant, because the probability that you get a payout is equal to the chance that a block is found in the next 600 shares, which is always the same because the hashing process is memoryless.
If a block is found in the first 599 shares, the extra is paid to me. On average, 36% of the subsidy of a block will go to me as a result of this. This is a trade-off between minimizing the payment to some central entity and having lower variance in payouts. If the proportion going to me were reduced by half, variance would double. I believe that this is an acceptable compromise.
If you find a share in the sharechain, there is about a 64% chance that you will get a payout (eg. that a block will be found in the next 599 shares). Using my portion of the payouts (once they mature), as many of the shares that didn't receive a direct payout as possible will be paid, starting from the latest ones in each chain. This process can be done at any time because shares will be recorded (It's an option in the p2pool client) and traced backwards from generated blocks to the first shares that need to be paid.
The program can include transactions besides the generation transaction in generated blocks if your Bitcoin client is patched to have the RPC command 'getrawtransaction'. If you'd like, you can build it yourself; otherwise, it might be pulled into some future release.
The process is completely open – anybody can record shares and examine them to make sure that I am keeping exactly what I say. In addition, anybody can gather statistics such as the pool's hashrate. On that note, I plan to take no fee for myself at the start, but later increase it to .5%.

From looking at the board, if you are using GPUs that take 2 spaces, they will be right next to each other with very little space in between. I tried that and was getting temperatures in the 90Cs when overclocked and running at 85% on fans.
I thought about going this route too, but the value is not there. A 3x slot mobo cost almost $100 more than a cheap 2x slot mobo, in addition the power supply cost at least $50 more. So you have a $150 overhead just to add 1 extra card, and heat with 3 card setup also becoming more of a problem.
I think you are far better off spending the extra money upgrade to a better 2x card setup with a cheap mobo.
im running the 5870 in the #1 slot which is on top so it runs a bit warmer but gets more air.
5870 @ 88C
5830 @ 76C
5830 @ 68C
using MSI Afterburner i have custom set the fans to run faster than auto settings, i have also install 3 extra case fans... guess it prbly helps that the unit is sitting beside a central air vent pulling in A/C!
Orignal From: What a good AM3 board with 3 PCI-e slots?
What is everyone using for a 3 card setup, without using 1x extension cables - 3 slots on the board with proper spacing?
i'll second the asrock extreme4. really nice board. I'm running 3x5830's on it.

Why don't pools pay out the full BTC amount?
The only pool I've used that pays out the full amount of BTC is Swepool. Other pools like Deepbit will only pay out a portion.
For example, if you had 1.79658246 in your Slush balance, you would only receive 1.79 BTC. Only Swepool pays out the full amount so that your remaining balance is 0 BTC
For example, if you had 1.79658246 in your Slush balance, you would only receive 1.79 BTC.
Possibility to send full amount thru bitcoin network is pretty new, not everyone has newest client, so I simply didn't turn on full payouts yet. But technically there's no reason to cut payouts to two decimal places.

Where was Bitcoin in 2010?
For those who found out about Bitcoin in 2010, how did you find out about it?
Reddit? Digg? Word of mouth? (If so, what kind of groups do you hang out with, and what part of the country do you live in?)
Here's what I'm getting at:
Pesonally, I've been into number-crunching "distributed computing" projects for years. I dabbled in several projects using BOINC (ClimatePrediction.net, etc.) and didn't get a single red cent for doing so. I used to look at the main homepage for distributed computing -- distributedcomputing.info -- to see if "maybe today" they added some good projects -- maybe even ones that could make a few cents each week!
Here's the real irony: Since I switched to Linux, which was last summer -- I installed BOINC and joined one of the projects available to participate in (only some would work on Linux). I ran it for a few days, then realized I was spending electricity for nothing, and quit.
But my point is: I was looking for a distributed computing project like Bitcoins -- it would have been a dream for me! But it wasn't even mentioned on distributedcomputing.info. If it wasn't mentioned there, where was it mentioned?
Even if BTC were only $0.25 each, even if you couldn't buy anything with them -- I would have "been there" and really got into it. I'm not just saying this with 20/20 hindsight...as I said, I spend a lot MORE time getting nothing but a score with projects like this (distributed computing).
So my question is -- HOW did everyone else who discovered it before, say, May 2011, find out about it? I'm lucky I kept an eye on Cryptogon.com -- he mentioned it on his blog, and that's when I found out about it.

4x 6870 Windows 7 Miner Crash
got some issues with my new Rig.
Got 4x 6870 running on Windows 7 64 bit.
I can mine with 3 cards without any problems, as soon as i plug in the dummy plug for the 4th card the miner won't start anymore, just crashes instant (tried: Phoenix Miner, Phoenix Rising, GUIMiner).
Got a 1200w high quality PSU (Silverstone) with a lot of ampere etc. Mainboard is a MSI 890FXA-GD70.
I tried to connect 2 cards with a crossfire cable and put the dummy plugs into the 2 other cards.
This is working, but i can't adjust the core clocks, memory etc. and the crossfire mining performance is about 15% lower.
I remember some older thread with the same problem but i can't manage to find it anymore
MSI Afterburner won't start either "Unable to initialize display driver wrapper".
Any suggestions? I can switch to a linux distribution too if this will help.

Buying a new PC... anything I should look for in regards to BitCoin mining?
My PC is on its last legs and I am getting a new one. I am using it for personal mostly (emails, browsing, coding etc.) but I want to some mining when I'm not using it. I understand I won't be raking in the coins, but I figured why not play with a great new technology? Is their anything I should look for when PC shopping?
AMD 58xx, 5970, 68xx or 69xx are the cards you want specifically for mining. Any of them with the arguable exception of the 5830 will serve you well for gaming too.

Someone needs to start a betting pool on when Mt. Gox will _actually_ open
You know that other thread with the $300 bet on what a bitcoin is going to be worth in a month or two.
Someone needs to start a betting pool for when Mt.Gox will actually open. Announced time is what 24-25 hours from now?
We need something like one of those betting pools where there's a timeline split into groups - like say 1 hour increments. You pay X amount to take an hour slot, say 1 BTC. And whoever gets it right gets the whole pool.
That's what I was implying.

All Mt. Gox participants are making that wager everyday. In fact, we're making a similar wager with our local wallets it seems.

I got a HD6950 which when on windows had 1.2 coreclock and temps was ridiculously high (upto 90C!)
i put it into linux and voltage is 1.1 and i cannot raise this.
The card is only stable (24/7 stable) to around 885Mhz on stock voltage, and there is lots of room temp wise now, running at max 67C.
Also core clock was 850 on windows, and 800 on linux by default oO;
So how can i increase the voltage?
EDIT: CCC does not have the +20% power thing, or any performance settings under linux. Am using LinuxCoin.
1EiAKUmTVtqXsaGLKQQVvLT9DDnHsT7jTZ
How could it be more stable?
You'll notice that normally a card is set with a widely varying range of values. Rapidly switching between these values can cause issues - lock ups, hangs, driver crashes, etc.
In normal use, you're less likely to notice (and you're less likely to trigger the cycles rapidly). For example, you would start a game at which point it would go through the different profiles until it reached peak performance (or switch directly to it). It would stay in this mode for a decent amount of time and then eventually go backward through the profiles when the game ended.
In mining, you might notice you rapidly flip between these profiles when things like network connectivity get in the way. Your card will go from 99% GPU usage at the highest performance profile down to the lowest settings and then immediately back up in a very, very short amount of time. Some cards don't handle this very well, and anyone that has repeatedly locked up a card starting/restarting different miners or those that have tried to set aticonfig/AMDOverDriveCtrl values while a miner is running can attest to the hair-pulling it causes.
Again, some cards can handle all the up-and-down mode switching without issue. in b4 "I do that all the time!1111"

What will price of btc be within first 24 hours of trading?
This poll is retarded. I don't like any of those options. I'm expecting it will align with TradeHill however.
How is it retarded. The trading range has been basically 10-30$ for the past couple weeks and when mtgox shutdown it was like 17 or something.

Catalyst 11.6 + phoenix 1.50 + ATI-APP-SDK v2.4 (650.9) testing results
Have suddenly found out that there are Catalyst 11.6 and Phoenix 1.50 updates out. I immidiately downloaded and installed them!
As for ATI drivers I uninstalled them via ATI's official Catalyst setup manager. And then sweeped them via driver sweeper 3.1.0 in safe mode.
I am mining with GUI miner using Phoenix+Phatk on W7x64 SP1 Professional. All VGAs are in CrossFire.
VGAs are 4x5870
clocks are (core\mem) 990\300 as for the ASUS HD 5870 V2 and 960\300 as for other 3xGigabyte GV-R587UD-1GD
flags are VECTORS BFI_INT FASTLOOP=false WORKSIZE=256 AGGRESSION=13
The CPU load is something I haven't experienced on any of my machines, what kinds of processors are you using and what OS's?
With 11.6 on Win7 64bit and an unlocked 4x Deneb core I only ever see a maximum of 15% load on one of the cores and I haven't needed the affinity locks. Strange?
results are
423 Mhash\sec for Gigabyte cards and 436 Mhash\sec for ASUS card.
Update:
Changed mem clocks to 365 for all cards and got + ~2.5 Mhash\sec.
On my machine there's only high CPU load with aggression=10 or higher.
With lower aggression there's almost no CPU load.
This is with Win 7 64bit, Athlon 64 X2 6000 and a single 6870 card.

Radeon HD 5770 - One or two GPU's?
I'm trying to mine with my Radeon 5770 and it working o.k. ~200Mh/sec using m0mchil's python miner.
Does this card have one GPU or two? When I run 'poclbm.exe' it just lists one GPU and one CPU device, is that correct?
I have 6 Radeon HD 5770 on three motherboards that I got from Newegg a few weeks ago given the limited choices. Four are Sapphire cards that run 10 degrees C cooler than the alternatives. One of the Sapphire HD 5770's crashes when overclocked so I leave it alone.
The three rigs yield say 1145 MH/sec and the shared UPS draws 850 watts. I keep the rigs in the crawl space under my Austin home where the ambient temperature is 30 degrees C - with no air conditioning.
I am very satisfied with these cards for mining.

The bank borrows 100 BTC to some party for a month for 3 BTC
there is a simple legit way to generate interest on Bitcoin without risk: borrowing it for shorting.
The bank borrows 100 BTC to some party for a month for 3 BTC. It gives 2.5 BTC to the person depositing the BTC and keeps 0.5 BTC as fee.
Sombody wants to short BTC. It borrows 100 BTC, paying 3 BTC for this privilege to the bank. It sells the 100 BTC. One month later it buys the BTC back (hopefully for a lower price) and gives it back to the bank. The profit covers the commission.
The central banks do this with gold for example, earning interest with zero risk. This assumes no counter-party risk, but this is what contracts are for. Of course, in Bitcoin world everything flies, no contracts needed
I keep hearing variations on this theme -- like no contracts or security or regulation is possible with bitcoins. It is, and I imagine many transactions eventually being kept in a regulated and insured bitcoin bank for example or very detailed legally binding contracts written between involved parties. There is nothing about bitcoin that prevents such legally binding contracts from being formed and enforced.
As far as a bitcoin bank, there are a variety of ways such a bank could generate an interest rate. Certainly speculating in other markets could be part of it and there is a possibility that the bank could take a loss. Same with lending bitcoins out at interest but having enough total capital to cover a "bank run". I would not entrust my coins in a bitcoin bank unless it was clear what our legal arrangement would be and what their liability would be in case of loss of my funds and how that would be enforced though.
You could absolutely run a bank, but I would only put my money in it if it did NOT use fractional reserve practices
I.e. there are two types of accounts at this hypothetical bank, one type that is essentially a checking account, generates no interest and the depositor actually pays a small fee to have it sit there (maybe .2% or 10BTC, whichever is less monthly) - The bank then secures the funds, insures the deposit (if the bank gets robbed, the bank is responsible for replacing deposits since protecting them is its primary job here), and collects the fee for holding the money. This money is NOT lent out.
The other type of account would be the time-deposit account, as described by someone earlier - Basically by depositing your money for a given legnth of time, you are lending it to the bank who pays you interest for it (This could be as high as 10%, depending on competition for investable BTC vs. number of projects/individuals seeking loans), and then the bank lends it out to one or many participants, again for a length of time no longer than the term of the deposit. The bank charges a higher percentage than it pays the depositor(s), and at the end of the agreement the debter pays back the bank who pays back the borrower with everyone in the chain getting interest for their involvement. If the loan(s) go bad, the bank takes the hit because their primary role in this capacity is to investigate and vouch for the lenders they loan money to. This means you wouldn't be able to just ask for a loan and get one, but rather would need to either provide some collateral or have a very established reputation with the bank and a history of paying back on time.
So many of these problems are solved because it is in everyones best interest to make sure things go smoothly - Nobody gets a free lunch, but everybody benefits in a way that reflects real costs.

How can Bitcoin help my people in Venezuela?
I have family and friends in Venezuela who want to purchase computers and cameras from the US, but have a limit imposed by the government of 400.00 USD Max per year on On-line purchases. I do not live in Venezuela so I do not know any details of why this is so...Can Bitcoin Help? How about Cuba?
But how is that enforced? I guess the shop does not control if you are buying from Venezuela or wherever. Probably the government checks the goods when they go through the fronteir and checks that they are not more expensive than the limit.
In this case the form of payment is kind of irrelevant. If this is not the case and the control is in the money part then Bitcoin might be of help.
1Q4pxzZHnXCfVpWig6Q6YgpdN7AkpPNRjAi
Then it seems Bitcoin could help. What I dont understand is what is stopping you from getting their money, buying the computer (or whatever) for them in New York and then send it to Venezuela. If the problem is on how they wire you money then Bitcoin might help, the only problem is how do they buy bitcoins. I dont know if there is anyone selling bitcoins in Venezuela. You would not have problems changing bitcoins for dollars to buy the stuff and maybe you can even find a shop that accepts bitcoins.

I've got 4 normal 5850's on a Corsair TX950 1HSj4CoNarcJ2B8Mi2EY6AtDWkUemYTWkQ
So I've got this one 6-pin 5850. I'm wondering how many I could actually run on a 950w power supply.
Right now, I've got 4 normal 5850's on a Corsair TX950. They use two 6-pins. So I'm guessing i could fit maybe...6 of the one pin ones?
What about 5770's? Do they use the same power draw if they have the same number of connectors (1 6 pin)? Would this mean that I could use 3 5770s and 3 5850s?

What does the 5870 get? I'll have to start looking for those cards.
Funny thing is tigerdirect.ca has the 5850 for sale for about $250 a piece and the 6870 for about $220. I'm also looking at both visiontek for the lifetime warranty. I was just curious why the "better" GPU was $30 less

Since there are scams and hacks a-plenty these days, you would think that Deepbit's website would be overhauled to allow a little more customization with regard to user accounts. I'd like to be able to change my email address but there doesn't appear to be a way to do it.
What does the lock my bitcoin address forever mean? Who knows, there's no help on the page. The only help the site gives is info on how to set up a miner. I'd like to start fresh and create a new presence, new email, etc. Whats the best way to go about it besides joining another pool?

Currently they are down to 11.5GHash/s
It may also be that somebody is/was doing the thing where they withhold solved blocks just to screw the pool. Why would they do that? Well...swepool.net isn't that big of a pool. It does have a nice fee structure. Otherwise though it doesn't really make any sense for somebody to waste hashing power just to attack a pool. There's nothing rational that could be accomplished, so it's just dickery, if that is what is going on. And it's a very beatable thing with a little help.
In any case, the hash rate was up around 70GHash/s when all was well and normal...but people started jumping off when the block hit ~24 hours and then the difficulty changed...then people saw the rate decreasing and they left too.
Currently they are down to 11.5GHash/s.
In any case, even if you like your current pool, it should be very easy for people now to set up another .bat file, and it's good to have a few pools ready to go. It should take like two minutes to set up.
They have a nice fee structure, nice little setup overall, and they just need to break out of the death spiral they are caught in with the block that isn't being solved and the people jumping off.

6xxx install for 64 bit cpu
I did choose to install the SSH option just in case I use it later... figured it would not hurt to have the option installed for some later time I might experiment with it.
Symptoms:
I start up Ubuntu. Open a terminal and run one of the four miner instances (two for each 6990 card). I open another terminal window and set the fan speed to 60%.
I would open another terminal window and start another miner.. etc.. All would be cooking along fine. However, after a bit of time [and this is true even if I was ruinning only a single miner instance] the screen goes black, the fans slow down... apparently the miners stop mining. A couple times it seemed to happen when I moved or touched the keyboard or mouse. But that could be coincidental..but does seem suspiciously connected somehow. My keyboard and mouse are fine. So, the whole screen goes black, but there is a cursor at the left top and I can type stuff...but it doesn't do anything expect show what I typed. It's not the terminal...it's some other kind of mode. CNTRL+ALT+DEL reboots it. What is that black screen anyway?
I end up having to reboot each time... start miners...and [soon thereafter] it all shuts down again to the black screen of...frustration.

CPU mining - revenue vs. costs
I am interested in, do you use your CPUs for mining? Do you mind the additional energy costs?
Does CPU mining pay off for you at the end?
I am using my GPU for mining and was using the CPU as well as a second miner.
After considering all variables and calculating the ROI I stopped CPU mining.
Let me explain my calculations:
My i72600K @4.6GHz produces 23.3 MHash/sec while the system consumes 110 Watts energy in addition (no GPU mining). This means, with a difficulty of 877226 you need to let it run for 5 years and 46 days to get a Block. Breaking this down with a conversion rate of $15/BTC you end up at $0.40 Cents/day (or $12.29/month).
Using my energy costs ($0.25/kWh) I spend $0.66/day for the additional energy. This makes a profit of minus $0.26/day (or loss of $7.89/month)
That's why I stopped CPU mining, because for me (who I do have to pay for my energy) it's a loss at the end of the day.

No, sorry, douchenozzles won't keep the video card cool enough. Maybe a full immersion technique, but that is beyond the scope of this thread.
I don't mind the video cards exploding, just as long as they're not near anything flammable, that could get nasty quick

Our faith rests on the utility of bitcoin to make the world a bette
7200 Bitcoins need to be sold on an average day to soak up the liquidity provided by mining and maintain a stable price. In dollars this translates roughly to a little more than $100,000/day. Assuming there are 20,000 true believers, that means each of us on average would need to buy $5 worth of bitcoins every day.
Speculators with no faith will need something to speculate with, so this soaks up some more liquidity and so will others such as traders betting that the price will fall less than the amount they would otherwise have to pay using other payment methods will help. But we can't always depend on them.
Our faith rests on the utility of bitcoin to make the world a better, more prosperous and more free place, based on our understanding of economics. Hard money advocates claim that bitcoin will fail because it's not backed by anything. They are wrong. It's backed by us, the ones who would see bitcoin succeed, even if we personally never make a dime from it. To see our vision come to fruition, we may have to keep a certain amount of bitcoins that we won't sell. ever. I am prepared to do just that. Christians tithe. Bitcoiners hoard.
So are the Christians right? Is the love of money the root of all evil? I guess that depends on what exactly is meant by such a claim. I for one don't love money for it's own sake or for it's ability to gain me power over others, but I do love the freedom it brings to me and to other peaceful folks. Freedom from the necessity the double coincidence of wants. Freedom to specialize according to our abilities. Freedom to do as we individuals, not others, see fit and yet to live without conflict among them.
Maybe our numbers will grow and our burden will be reduced as it is shared by new converts. Maybe in time the utility of Bitcoin will become so obvious that it won't need us anymore at all. Maybe, but until and unless that time comes, we are the keepers of the flame, and I for one will do my part, my ~$150/month. I will do my part to break the iron grip of our bankster overlords. Hell, I was spending almost that much on beer anyway. Maybe redirecting that money into Bitcoin will help me lose that 20 pounds I keep trying to get rid of. I will do my part. If you are able and willing join me. Success isn't guaranteed, but it's gonna be an adventure!

A Random thought.
So I've been following this whole mtGox thing pretty closely, and also been getting e-mails from tradehill non-stop!
Then I read the facial recognition article about the mtGox video and find out that it was most likely their wallet that was compromised and you have to think..
If you compromised the main exchange, why not just steal everyones bitcoin?
Basically, what if the tradehill guys where behind the mtgox hack and have now used it as a way to completely usurp the bitcoin exchange and trading market and all the fees, etc in the process..
