Here is my Extreme tweaker settings and tell me what I should change...( I get constant BSOD if I dont put timings mode at 3N)

***on-board jumper dependant
everything is stable for 2 hours Linx stable...need to tweak a couple of Value...but the Metro 2033 Keep crashing when I play, and 3d mark Vantage also gives me some annoying vertical line before freezing like Metro 2033

Thanks Guys
I edited your template with settings I would try, so you can give it a shot if you want.

No! That is too much!

This is with keeping the memory multi at the lowest too. I don't think it is a voltage issue, as one minute it is prime/linx stable, a couple more MHz and it just dies.
Correct. 1.5V VTT (QPI/DRAM) IS too much! Why don't you post your settings using BIOS template, so people could check it out?

+1 Flashed to 0702 last night and it's working fine. Folding 22 hrs now. No obvious faults as it works with settings as before. Didn't have a chance to test if it's better, requires less voltage for Vcore, VTT, etc.
