**Official ABIT IX38 QuadGT Review/Overclock/Guide Thread**

[ust]

Hi again matey

Sorry I can see what you are talking about. I'll try to express myself more thoroughly now...

First I tried to follow your 400*9 template, but Prime failed right away with those settings. So i bumped up my Vcore to 1.4250 and lowered the FSB Frq. to 389 from 400. With these settings, as said in my previous post, one core failed after 1 hour and 80 mins. while the other three went on with no errors for 52 hours.

Okay, back to present time. I'm advices by Supershanks and R*r to bump up my VTT and MCH, but decided to try out 9*400 again since it seem to be a sweetspot for the CPU judging from the countless OC threads here.

So I tried with a higher VTT and MCH to reach 9*400 and this is where we are now

With these settings 2 of the cores fail immidiately:
