E4500 and GA-G31M-ES2L won't hold O/C

Specs: Windows 7, E4500/Crucial Ballistix
Hey there,

I have done some research on overclocking and I decided to give it a try. My current setup is:

E4500 C2D
2 GB Crucial Ballistix DDR2 6400 RAM
Aftermarket CPU cooler

I have messed around with a few different overclocks but I can't get it to stay. Everytime I save and exit the BIOS, my computer will restart.. not POST.. then restart again and un-do the overclock.

Here are the settings that I tried:

Multiplier: 8
Bus speed: 400
V-Core: 1.3875 v
PCI-E: 100 (default)
DDR2: +.2v
Performance Enhance: Standard
FSB: .1 V

I also tried FSB's of: 350, 300, 275 but I have the same result each time.

The weird this is that the multiplier will not change but the FSB will always revert back to 200. Any ideas on what I'm doing wrong? Thanks in advance for the help guys.

Don't mix FSB and CPU frequency (FSB/4=CPU FREQ).
The problem here is u have bad(cheap) board which isn't good overclocker(because of bad chipset G31 + ICH7 and locked mem multi).

u have two options 1. use it as it is(set your ram to run at ddr 800mhz then u are done) or 2. oc a little.

If u decide to oc here are the settings u should set
-lock pci @ 100mhz
-disable speed step
-disable spread spectrum
-disable cpu enhanced state(CIE)
-underclock ram to 667 ddr(the mem mult should be 3.33) and u can't underclock to 533 or 400 because the board(both version) don't support.
-don't increase any voltage

start by increasing cpu frequency to 210(don't decrease cpu multi) then check ram clock(make sure it doesn't exceed 800 ddr) if it exceed u need to increase mem voltage(increasing mem voltage can fry board or increase mem temp which will reduce mem life span).
