And there's your problem right there. IBT is not a good stress tester for AMD's. period.

There's a mod on here that ran IBT for 18.5 hours on his x6 Thuban. Passed with flying colors. He fires up Folding at home, BSOD within 5 minutes.
With the same settings he ran prime95 and failed, readjusted his BIOS settings on his OC, ran P95 for 24 hours, and passed. He fires up F@H and it's totally stable.
He's since removed IBT from his stress testing regimen.

For real stability, run F@H and P95. While it's not the end all be all and will guarantee that your OC is stable, it's the closest thing I've found to making it so.
So try running F@H with your current settings and lets see if it fails. I'm betting that it will, and rather quickly at that.

^ I ran P95 before for 2hours, perfectly stable at 1.1625V.

This is a mobile chip guys, not a desktop.

Also, updating the BIOS fixed the problem.

Good for you... but if you had same issue (your BSOD error codes says that your CPU and CPU NB needs more voltage) <- this will fix that . Good luck.

2 hours isn't stable. Not by any means. Personally, I'd hesitate to call even 12 hours stable. 36 I'm ok with.

I agree, for complete stability of the entire system you need to run a minimum of 12HRS in Prime95. Although rare, data corruption can happen from an unstable CPU with less than 10HRS of Prime. There are plenty of stress programs such as Y-Cruncher that can give you a quicker idea of the state of stability, but ultimately it's recommended that you finish off with a 12HR run in Prime. 24HRS has become my personal gold standard, but the maker of Prime95 states you should run for a few days - not that he would know anything about stability, right?
