Why the games freezes when 370-390FSB ?

[X7007]

I tried everything, but all games always freeze after some long gaming , 1hr or 2hr, and then BSOD with Nv4_disp.dll.

What to do ?

i tried all good voltage MCH 1.65 , Cpu 1.3365 , ICH 1.20 , FSB Ter 1.40

prime tested 24hr and memtest 18hr didnt find nothing.

The pci frequency is locked on 100, tried 104-105, 110, still happen.

Hyperpath disabled and everything i dont need.

Anything over 375ish to 400FSB STRESSES the NB alot. Either raise the Vcore to the NB, or go to 401FSB (this is where the NB strap changes) and see if your issue still happens.

K, i lvled up the CPU Voltage FSB and MCH voltages

CPU - 1.4225
FSB - 1.40
MCH - 1.75
ICH - 1.20

FSB at 401, will it fix my problem ?
