Asus P5KPL-C & E8400 problem

post #1 of 8
Thread Starter 
I decided to overclock my Intel C2D E8400 and raised CPU frequency from 333 MHz x 9.0 to 365 x 9.0 and when i tested system with prime and other programs it was stable. Now when i get to 370 x 9.0 or more something weird happens.

System is stable and boots up normally, but there goes a problem: network is not working. When i open any browser just weird symbols appear and error codes and none of MSN, Skype, Tunngle is working...
Anybody knows what is the problem ?

Instablity is known to cause everything from graphic glitches to ominous sounds.

Would raising voltage change anything about that ?

It may help, bump it a little bit.
If it doesn't, return the FSB to 365, I doubt that 5 * 9 MHz is critical for you.

I guess you're running a high PCI-E frequency. Try to decrease the PCI-E frequency and report back.

PCI Express frequency is 1106.00 MHz, but i seem to be unable to change it in BIOS... so i guess the main thing limiting my overclock is Motherboard, which is not a pearl with OC

Is there any way to change PCI-E frequency in Windows ?

Are you sure its at 1106MHz, the default PCIE frequency is 100MHz and it changes linearly with FSB. High PCIE freq. will ruin your 8800GT and damage IDE HDDs.
And yea, that mobo isn't meant for OCing.

Yes i know its weird, but Everest says its 1106 MHz... You maybe know any other programs that would show PCI-E frequency ?
