Stock and normal use its expected to last 7 years.
Overclocking it will bring the life down a bit as well as running 24/7 but it should still last 2-3 years if you keep the temps 75C or lower.
By that time the card will be out dated anyway and you would be able to pick up one thats more powerful for 1/4 the price.

What size PSU are you using.
Also do you have any power saving features enabled.

How can you leave off: ClockTweak from the BitCoin community's very own phelix? I personally vote for ClockTweak. +1 |

How I've been explaining it to friends is.
You rent out your GFX power to crunch numbers.

Good to see another NZer mining.
Overclocking does bump the power usage up but under-clocking the memory brings it back down.
Just need to find a good balance.

Get 277Mhash with 990mhz core, 300 with 1040mhz core.

Positive:
Mining faster then 11.6, Dont need dummy plugs. 100% CPU seems to be fixed.
Negative:
Voltage control stopped working, Ram usage went up.

High 70Cs are the most id have on a card mining since as heat goes up its going to use more power and have a shorter life.
100C is way to much get it down and youll see the Mhash go up since it wont be slowing its self to prevent damage.

Will take pics next time I have the PC offline.

When your sleeping and you wake up because the PC makes a weird noise.
Has happened to me a few times.

Just the stock TIM that came on the cooler, and just some budget stuff on the coper plate on the gpu.
Would be better if pumps were on full time and I used high grade TIM but im more then impressed with the results for 138NZD (119USD)
CPU pump turns off at 25C since thats the lowest point I could get the cpu pin header to enable and I didnt want to wire it directly to the 12V since it would be noisy then.
No idea the exact point the gpu pump is turning off but I cant hear it till 30C and Id rather not mess around with the fan setting in trixx when its running 1/4 the temp it use to run.

Temp in the room was 2C yesterday.
Its up to 6C today but full load is just sitting on 26C cpu and gpu is at 40C.
In other words, your temps aren't really comparable since your room temperature is ridiculously low (just above freezing). They are comparable to the idle and stock cooling since that was tested the same day at the same air temp. Would of hated to see what the temps would of been like in summer when it gets up 28C with the old stock cooling. Got the chipset temp down but moving the radiator to the top of the pc and cutting a hole to mount it, Now the front fan can get air around the chip set, Has been sitting at 40C full load and also bought the gpu2/3 temps down since same fan blows on gfx card. PWM is getting up in temp now 48C up from 41C so its now the hottest part, so ill need to get some heat sinks for that, Or some cable ties might help since the cables are blocking air flow to it. |

open up gpu-z and see how many it has.
If where you bought it from stated how many SP it had and was wrong that could be a reason to return it and get another card.

Yes, 11 degrees celcius is 50 degrees fahrenheit. Unless you're living in Siberia, that isn't your real temperature
Live in New Zealand its, winter at the moment. Looking out my window I can see snow on the mountain and the wind was coming from that direction yesterday. |

Not going to test idle since that means stopping all my mining for a hour.
GPU temp 2/3 in gpuz are getting up to 75C, stock cooling the sat around 80C but they were getting heated by the gpu I suspect.
Cleaned the chipset cooler and new thermal compound but its still getting to 50C which is the hottest part of my PC now. Its a nforce 4 and from google searching they are meant to be good up to 60C with there max safe temp being 70C

Not many,
With my overclocked 6850 im getting 277Mhash/s which works out to 0.2 BTC per 24hours at current difficulty.
Stock clocked 6850 only gets about 208Mhash/s

1 stale out of 1XXX accepted for me on BTCGuild with 1.4.1 speed isnt too bad is only 0.4mhash/s slower then the latest modified phatk.

Just because you found a block in a pool doesnt mean you would of found it solo mining.
Heres a example
in a pool youd have like a 1 in 7,000 change of finding a block. On your own it would be more like 1 in 700,000

Just 2X Antec KUHLER H2O 620, CPU cooler kits.
Were for sale for $69 ech.
Mounts to
• Intel sockets LGA 1366, 1155, 1156, 775
• AMD sockets AM3+, AM2+, AM3, AM2
Was easy enough to adapt to 939, Used the stock backing plate with the mobo then used the screw extenders that came with the blue orb 2. Took the intel mount bent the 2 opposing screw holes in another 5-10mm and cut off the 2 extra.
adapting it to the gpu was a bit more work. Took 3mm thick coper plate drilled holes so the amd socket mount holes lined up with it then trimmed it to that size. Then drilled 4 more holes to match the gpu mounting holes. Used some screws I had in garage then soldered them in place and milled the heads flat. Then just bolted it all up together.
Mounted the 2 radiators to each other with the fans eather side sucking in at the front and blowing out at the back on to the gfx card so the pmw and ram still have some air flow over them.
If I was to do it again id use more coper on the gfx card so it makes contact with the ram as well but im just going to get some ram heat sinks tomorrow.
I could of probably pieced together cheap parts so there was only 1 larger radiator but Id rather have a sealed off the shelf kit at this price since its at least Iv got a warranty for if it leaks and damages anything.
