This card is already close to the maximum number of watts than can be handled by its VRMs and the PCI-e connectors/cables. I would not recommend increasing voltages to try and get more kh/s something will fail somewhere. Remember that in the low-voltage high-current world of GPU's even a tiny increase in voltage can result in a much increased power consumption and hence thermal output (Power = Volts*Amps). You'd be much safer with 2x 7970's.

Yeah it's not too hard to work out if a card is dead. If its under warranty then a RMA is the way to go. If it's out of warranty you could sell it on ebay for parts (surprisingly good money doing that, since some people like to claim they can fix them). Of course you could try baking the card if you suspect that the problem might be a solder/connectivity problem on the board, but that is essentially a 'last resort'.

All unusual or specific situations, I guess. There are always exceptions. I don't see why anyone would mine on Server 2008, unless you actually had some nice cards in a real server that had hardware which truly required that OS.

Just to be clear, have you followed their guide?

You're question is really SHA-256 or scrypt algo coin. If he's getting 256 Mh/s on a scrypt altcoin I will buy his card for $9999. So we can assume it's BTC, PPC, or TRC (the common non-merge-mined SHA-256 coins)

From a scientific perspective that is a completely meaningless statement. How much lactic acid will build up and in what concentration?. What effect will this have? How quickly is it removed or neutralized? What concentration threshold must be reached for any negative effects to be experienced (pain?).

A lot of people think that 'acid = bad' because of a poor understanding of chemistry and/or the world around them, neglecting the fact that the human body contains countless acidic substances that perform a multitude of tasks either directly or indirectly or form as a by-product of other processes. Saying exercise will result in lactic acid buildup is almost meaningless even if it is true.

Even at 1 BTC and very modest difficulty increases it has been shown time and time again using many different calculation methods that you cannot possibly make back your initial investment mining BTC with these things unless they drop in price greatly, perhaps as low as 0.15 BTC/ea

Unless the operator of the bitcoin wiki site is trolling through the newbie section of this forum, no one will have the answer. And I like to think the operator is too busy getting his/her site back up

CUDA is a nvidia technology and we don't care about that here. Mining takes advantage of OpenCl on ATI/AMD GPU's.

My suggestion would be to look at using something like cgminer instead of your current miner. https://bitcointalk.org/index.php?topic=28402.0

It is arguably more complicated but is far superior in many ways to what you are using.

I'd suggest you download it and run cgminer.exe and follow the prompts. Although a lot of people like to run this miner using .bat files and/or shortcut parameters, instead I find it's easier to run the program directly and edit the config file, which the program can save (when it is setup, press S then W and then enter to save the default named config file).

Tip:  when you enter URL's and things into command prompt you can click the icon in the top left of the program and go Edit->Paste

Alternatively you could use something like FurMark or OCCT to stress test the card and make sure its stable. Mining involves pushing the hardware to its maximum so its critical that it is fully stable under these conditions.

It will be available when it is no longer unavailable.

When selling accounts its hard to ensure that the new buyer can maintain the account should the seller go and challenge support services and get his/her account handed back. Usually a careful analysis is required for each different service (steam in this case). Would definitely treat this very carefully.

1. Obtain 3D rendering cluster access
2. Ensure it's running nVidia cards (extra points if Tesla's)
3. Commence cluster mining on all cores!
4. Earn very little coin
5. Wait for admin/techies to find out and lose your job.
6. ...?
7. Profit!

 

HD 7570 has 624 GFLOP/s. (http://en.wikipedia.org/wiki/Comparison_of_AMD_graphics_processing_units)

I'd estimate you may get up to 85 MH/s with it mining SHA-256 based coins (eg. bitcoin) or roughly 85 KH/s with it mining scrypt based coins (eg. litecoins).

This is not a lot. You won't make much from mining with it. As it's OEM it might have overheating problems, especially with scrypt mining because of the high load on the memory (many OEM cards have no memory cooling).

Proceed with caution. I'd monitor core temps very closely with GPU-Z and memory chip temps with an IR thermometer or your finger if your feeling lucky.

Why would you not just use one of the altcoin exchanges.... I would steer clear of this... newbie brothers and sisters.

 

In summary, buying a GPU based mining computer system will:

- Definitely not make your initial investment back if you directly mine for BTC (either solo or in a pool). *Unless you have amazingly cheap or free electricity
- Might make  you some money if you mine a good altcoin, the consensus is litecoin, but there are alternatives that are not based on scrypt

On the other hand, since it came up:

- You will DEFINITELY NOT make any money buying block erupter USB's unless they drop in price substantially again (down to 0.25 BTC or less to even consider it)

And using other ASIC hardware well that is irrelevant since there's thousands of people here who want to beat you to getting their hands on that hardware first... so good luck!

Pics or it didn't happen. That's a lot of power, a lot of heat, and a lot of hardware (at least $1200 worth, with waterblocks) to just have sitting around. I'd be interested to see your setup, if you really do have it.

Ebay/paypal disputes always fall down to proof of postage. There are very limited options that they accept as 'proof of postage'. For example in my country (Australia) the only accepted method is Australia Post Registered which comes with its own tracking number. Although it's recently been upgraded, that product used to have no online-tracking but ebay/paypal could call Australia Post and verify with their internal records things like the package details, destination, delivery status etc.

Can seller provide proof of postage?:
YES: --> SELLER WINS DISPUTE
NO: --> BUYER WINS DISPUTE --> FORCED REFUND

I imagine bitmit has a similar system. If you are ultra paranoid, you could film yourself packing the item up for shipping. This might be useful if disputing the condition of the arrived item. You should obviously pay a little extra for shipping methods that have some kind of tracking, online tracking would be the most convenient as I'm not sure bitmit mods would actually call couriers and postal services around the world like I know ebay/paypal has a whole department for.

- Is the wallet owner experience with computer security and maintaining a healthy and safe operating environment? Then bitcoin-qt might be for them. But there are those who will claim that bitcoin-qt should never be used on an online PC for large wallets...
- Is the wallet owner not the above? Eg your stereotypical clueless computer user who's most used program is Outlook Express? Well then a blockchain.info wallet might be a good idea, although there certainly still vulnerabilities in this case, it might be safer than a software client.
