Having some time off work is great for relaxing, but I got alittle bored and so decided to push the limits of my GTX570 SLI.
My cards coms pre overclocked to 841/1682/19xx, I'd been running them 24/7 at 910/1820/2200 @1.1V for about 6 months, no problems or signs of degradation.
The problem with the stock BIOS is that its max Vcore limit is 1.1V and this just wasnt enough so I edited the BIOS to allow for 1.188V then flashed both cards to this modded BIOS.
With more juice to play with I was soon benching 3DMark11 @ 1000Mhz Core, temps touching 50C for the hottest card.
After 3DMark11 I tried Unigene Heaven 2.5, This Bluescreened after about 20 seconds. At this point I thought that the overclock was just unstable. I turned in for the night
About 15 minutes ago I tried to play the BF3 Beta at my normal 24/7 Clocks and it instantly crashed and then my PC shut down. Apon rebooting I noticed that the second card wasn't listed in the control panel, in the nVidia panel or GPU-Z... I've reseated both cards, checked power cables ETC... no signs of damage but haven't checked under the waterblock yet.
It had 10 minutes of 1GHz glory, then died a sad death R.I.P GTX570 Beast Ed.
Sad times.
