Need help getting NB overclock stable.

post #1 of 4
Thread Starter 
Current overclock i want to achieve...:
FSB = 250
CPU Multi = 3625 (14.5) @ 1.35v at the moment
NB Multi = 2750 (11) @ 1.225v at the moment
HT = 2000 (8)
RAM = 1666 6-8-6-24-1T @ 1.73v at the moment

It works but when i run Prime95 i get an error and it stops working first on one core, then eventually all 6.
I also got freezes then i pushed the NB voltage to 1.25 and havent gotten any yet.

Was at this:
CPU Clock: 240*15 = 3600 @ 1.35v
CPU NB: 240*10 = 2400 @1.2v
HT: 240*9 = 2160 @1.22v
RAM: 240*6.66 = 1599 @1.71v

Basically everything is the same, just the northbridge isnt co-operating...

Your CPU/NB Vcore needs to be higher. @ 2800 NB I have to use 1.3-1.35V, so do others. So start there. However, your NB is pretty high. And I'm not sure that anything over 3200 NB gives your a big performance gain. So I think your better off trying to achieve a NB overclock of 2600 - 3200, depending on how high your CPU is OC. 4.0GHz CPU overclock, I'd say use 3200 NB. 3.6-3.8GHz CPU overclock, 2600-2800 NB.
