I think all reports of degradation I've read so far are people who delidded. I don't test above 1.4v for more than a few seconds myself, but since getting this chip in June, I've put it through hours and hours of testing in the 1.3v range (on core and cache), and a handful of hours right at 1.4v. No observable degradation so far. Not delidded (70C peak in games is good enough).
Now that's a pretty decent chip.
I just checked my temps in HWinfo and I'm surprised to find out how hot it is!
At 8am I was running chess, and the hottest core was core #2, with average temp of 69C. Now it's at 81.5C! (5pm now). I also just came back from the only Bsod this day, so Forceman could be onto something, maybe the instability could be temp related.
No bsod code, simply a lockup.
I have a monster typhoon airflow, I've done all I could.
D14 can only get you so far when you're on 1.425VID and 1.45v+ under load...
Well, between you and RushiMP, we'll know soon enough how bad the 1.4v range is for these chips...
