Did you pay out the transaction fees from this block? http://blockchain.info/block-index/333825/00000000000002327a29e7fdf539e773e960e631622c46cf859efebdbb78f9a8

It had over 111 BTC in fees, over 4 times the block reward.

Wow thats a lot of BTC. Sorry for your loss. Raw transactions are dangerous.

Reboot your machine. I get this on my HDTV once I change my clocks from the default. If it still persists, then somehow the clock speed is "locked" with your driver settings. I don't know where this setting is, but found fully uninstalling and reinstalling the driver and using driver sweeper in between will get rid of the "bad" clock speeds.

Btw this happens to me on a radeon 5870

Use a kill-a-watt. Make sure you arent pulling more power than what the power supply is rated for (factoring in inefficiencies). Also make sure to load balance if it's multi-rail. Quality of power supply makes a huge difference too. If it's a no-name, it probably will shut off/explode long before you hit it's rated capacity, or it will send out dirty power (Either too high/too low voltage, very bad ripple, or both). Get a good quality PSU. I have an NZXT HALE90 power supply rated for 750 watts continuous. It draws about 835 watts with 7 GPU's attached to it. It runs 24/7 with absolutely no problems at all. Assuming 88% efficiency, I still have about 15 watts of headroom on it.

I know its GCN. Still, the hashrate per mhz per shader is pretty damn close to a VLIW5

CPU mining is dead. Even the biggest, baddest $1000 CPU's may only be able to crank out 30 mhash/sec while consuming on the order of 200 watts of power. Don't bother. By comparisons, you can get a retail Radeon 6450, a very slow, low end GPU for about 30 bucks and it will also do about 30 mhash/sec at a tiny fraction of power, probably in the area of 15 watts. You can also find a Radeon 5970, a very high end dual GPU card for about $250 and it will do 700 mhash/sec with about 200 watts of energy.

Do not bother with CPU mining.

6870 is 850 MHz with 1120 shaders. 7970 is 925 MHz with 2048 shaders.
850*1120/925/2048 ~= 0.5025

A 6870's performance is about half of a 7970 as far as mining is concerned, and is probably less than half as fast for gaming (architecture improvements and whatnot) compared to 7970.

pass, but thanks for the offers. keep em coming. Also Amazon sold out of the OCZ ZX 1250W finally (They were asking $140 with free shipping).

Your opencl isnt installed correctly. Fully uninstall and reinstall it.

google it. dont be lazy

I'd probably take one for about $85 shipped. It must be game stable though (resellable condition)

this x1000. Were you the guy that bought a bunch of broken video cards that had the PCI-E common pins cut off? (Who in the hell even thought that would work?)
Also, FWIW, the first PCI-E lane (PCI-E 1x) consists of 7 pins after that chunk that got cut off.

Up. Still looking for an inexpensive, quality power supply.

What does one mean by headless? Does that mean no monitor, keyboard, and mouse? Just power and ethernet? Because thats what my miners are and they run windows. I just use UltraVNC instead of whatever the linux equivalent is in case I need to interact with it. Otherwise it automatically powers on whenever the power plugs it, automatically logs on, and automatically starts mining, overclocks, underclocks, etc without needing any interaction from me.

You should buy them. Granted when I bought my SSD from newegg (exact same model OP is selling), it decided to disappear once every couple days and required a complete power down and power up to detect the drive once again. I RMA'd it and the new drive has been 110% flawless. Was just a quirk I guess, but I absolutely love it. This SSD may be coming up on a year old, but it is still in the top tier of tomshardware's SSD lineup due to the capacity and toggle mode NAND providing amazing transfer numbers even 1 year later.

How much do you charge to fix video cards? I have a 5970 (not one you gave me) that will sometimes have a red light come up underneath the board by the PCI-E power connectors after some time of mining (maybe a minute, maybe an hour, maybe a week), and it freezes the entire computer, need to hard power off the entire computer before its detected again.

Just kinda fishing to see if its worth sending it out for a real reflow instead of baking in my oven (I still dont know if 8 minutes at 400F is working for me or not).

Edit without bumping: Hopefully, I may have jumped the gun about the gpu's actually going bad. I found one of my PCI-E power splitters taking on a brown tinge. I examined it closer and 2 of the 12v wires were darkened significantly. The middle wire was flawless, so power was probably only being supplied through 2 hot wires compared to 3 cool wires. Good thing I have lots of spares and also redid the wiring on that miner so all the 8 pin power plugs come directly from the power supply and the remaining 2 PCI-E power plugs get split into 4 and plug into the 6-pin power receptacles. Hopefully that works out better.

Another bump, interested in upgrading my heavily abused HALE90 750 watt PSU that's powering 7 GPU's. Got about 25 watts left of headroom on it; It's pulling 835 watts of power at 120 VAC, though I'm feeding it power from a dryer socket now. Multimeter shows 254 VAC last I checked, so it's probably in the neighborhood of 815 watts at the wall.

You must be doin something wrong. I have a 5850 @ 785/151 1v doing 328 mhash, which is more mhash than your 5850 at 850/600 stock volts. You must be losing a lot of money

SOunds a lot like a 5870 I have. System will not boot or post with problem 5870 in primary PCI-E slot or by itself. I can install it along side another card though. It does not having working display output. Fan is stuck at 100%. It is however detected and driver installs fine. It also mines fine as well, but voltage is possibly locked to something close to stock volts (920MHz at 1v = unheard of? Probably locked to something higher).
