25BTC each or 25BTC for both? If it's the former, thats a huge upmark; Even I didn't pay that much for one 9 months ago

I wasn't aware there was a reference 5830. Pics please.

What CPU's do you have?

Eligius won't pay out until you have accumulated approximately 0.67 BTC. This will take over a month for your puny gtx 580 to mine. Try finding a pool that allows micropayments if you need BTC that bad, or look for a bitcoin handout website.

Most cards will play nice with clock changing when there is a load on it. Some are temperamental, some damaged ones may throw a fit too. None of it with permanently damage a card though. Worst case your computer will freeze.

Because you're using the newest AMD APP, which is probably 2.7. 2.7 and 2.6 blow HORRIBLY for anything that doesn't absolutely require it (see radeon 7000 series). Use 2.1, 2.4, or 2.5 (I recommend 2.1, but you won't be able to use it on that driver. I think the newest driver that supports 2.1 is 12.3, but you should still probably use 11.12 or 12.1).

Uninstall the entire thing, delete amdocl64.dll, amdoclcl64.dll, and OpenCL.dll from C:\windows\system32 and amdocl.dll, amdoclcl.dll, and OpenCL.dll from C:\windows\SysWOW64. For whatever reason, amd app and opencl aren't properly uninstalled when you uninstall the driver.

Download and install 11.12. Link is here. http://support.amd.com/us/gpudownload/windows/previous/11/Pages/radeon.aspx?os=Windows%20Vista%20-%2064-Bit%20Edition&rev=11.12
Driver is mandatory as well as the amd app. Catalyst control center not necessary at all. Reboot for funsies.

Recommended to install SDK 2.1 as well, but you only need to install ONE THING from the package. Unfortunately I can't find a link on amd's site. You can either download and install the only package you need from my dropbox here: https://dl.dropbox.com/u/9768004/ATIStreamSDK_dev.msi or you can google for ati-stream-sdk-v2.1-vista-win7-64.exe and extract contents and navigate to Packages\Apps\ATIStreamSDK_Dev_win764a\ATIStreamSDK_dev.msi. This will create a second openCL platform called "ATI Stream" that many have found a little faster than 2.4/2.5 (I believe 2.5 comes with driver 11.12). Note: Most miners will NOT find the ATI Stream opencl platform unless AMD APP is also installed. Also, ATI Stream -must- be installed after AMD APP is installed.

After you install ATI Stream, you should be able to mine at proper speeds. You should get something like 195 mhash on a stock speed 6770. 1GHz would push about 230 mhash. Make sure you select the proper platform with your miners settings. With CGminer or BFGMiner, this is with the "gpu-platform" argument, followed by a number. 0 is the first platform, 1 is the second platform, etc.

Make sure you are using the phatk (or phatk2 if you are using phoenix) kernel, BFI_INT if using something other than CGMiner/BFGMiner, worksize of 128, and vectors enabled or set to 2 (depending on miner). Also it is recommended to set memory low, usually in the area of 160-190MHz depending on core speeds; the optimum ratio is close to a 5:1 core speed to memory speed. It takes some fiddling around, but you will see much lower temperatures and likely higher mhash than stock memory speeds.

also it looks like he installed not 11.12, but 12.10 (or something like that), judging from the amd app version.

Dunno why your 6770 isnt detecting. I got 32 gpus spread across 6 rigs and they all mine. Using 11.12 or 12.1 driver, ATI Stream SDK 2.1 installed in addition to whatever sdk is normally installed with those drivers. I select "gpu-platform" : 1 in my config file, uses the older faster sdk, mines away happily.

But I'm also not using any nvidia. Try just the 6770.

Getting much better stales and better connection to beta pool (port 8837) compared to main pool (8337). Proof in the pics.

Beta:

Using all of mine. I don't want to degrade the value of my existing 5870's. Sorry :/

Nowhere. ASIC doesn't exist in the hands of an end-user yet.

Being a mod doesn't necessarily mean it's more secure. A mod could have done no trades on the forums while a member did 1000 successful trades with no issue. Who would you trust more?

Wow this thread got thoroughly de-railed

Why not just return it for a full refund. People here won't pay more than retail unless they're brainless.

Got one of these. http://www.newegg.com/Product/Product.aspx?Item=N82E16814102883
Sapphire 5870 non-ref. 1.05v is the lowest voltage it'll go, and run about 860MHz core at that voltage and do about 399 mhash at those speeds. Stock volts is 1.2v, not sure what it'll peak for mining, but it's game stable at 890 core. I recently cleaned it up really good; No dust at all, fresh paste, fan oiled up, good to go. Card only.
5870 buy-it-nows on ebay are about $130, $140, etc. I could let it go for $120 shipped to US48. You pay any shipping over $10 if you are not part of US48.

I can take Bitcoins, Moneypak, Dwolla, Popmoney, Serve, Chase Quickpay, Cash in the mail, maybe others. Kinda sketchy about Paypal. Can anyone vouch for your legitimacy if you really need to use paypal?

Ima see if I can win the lottery and put in random numbers for the walmart card. It's only a 1 in 10,000 chance!

I needed a power supply -badly- so I just went looking around on the web. I settled on an OCZ ZX 1250W for $135 shipped from amazon (The 1KW version had good reviews from hardocp)

I'm going to pass on the ABS. It had a "fail" grade when reviewed at HARDOCP and I would rather not fry my expensive video cards because of the awful DC output quality.
I did reply to mrb's thread about getting an AX1200 though. If it falls through though, I am -still- looking for a quality power supply.

I'm tight on money, but also desperately need a higher capacity and more efficient power supply (My PC P&C 1KW-SR can't keep up anymore. It was a great power supply when it came out, but not so much anymore). I was going to offer $150 shipped for one AX1200 to 54501, but you'll probably counteroffer something higher, so I'll cut out the negotiating back and forth.

$165 shipped for one Corsair AX1200. I won't budge on this offer.

Have a Sapphire 5870 non-ref card. It is game tested and game stable up to clocks of 890/1250. I cleaned it up with good ol' soap n water to get rid of even the tinyest spec of dust and air dried it in the oven at 160F, as well as popped open the fan, cleaned it up the same way, and put some 3-in-1 oil to keep it running silently and smoothly for the foreseeable future. I already tested it ingame again and it is still rock solid at those clocks.

Would you be interested? I live in US.

Also interested in a GTX 680. Not interested in a Radeon because of bad microstutter with multi-gpu solutions, and no proper windowed multi-gpu support. Also I won't be tempted to bitcoin mine with it, so I can keep it running longer without 24/7 stress and having it break down.
