I tried to overclock my e8400 cpu and everytime i change the fsb to anything above 333, my computer will then restart then fail post. Its an endless loop and the only way to get my system back up is to reset my bios by taking cmos batt out and back in.

My specs are:
Intel e8400 dual core
msi g41m p34 motherboard
Corsair xms3 2x 4GB 1333mhz
Sapphire radeon 6870
Coolermaster 750w GX
windows 7

This is what I've done so far:
*set fsb to 370
*set northbridge volt to 1.19
*set cpu vtt to 1.29
*set cpu vt to 1.315
*set ram voltage to 1.60
*set ram ratio to 1:1.50

What am i doing wrong? Pls help.

If I remember correctly the G series chipsets were budge oriented and did not allow for high overclocks. Maybe you just reached your motherboards limit at 333 FSB. Try searching online to see if anybody has gotten a much higher overclock than you using the same motherboard+CPU combo

If all else fails you can try to install a better cooler for the NB and hope that the temps drop enough to allow for higher clocks. 775 era boards when their NB gets to hot they easily cause problems with the FSB.

More juice here set ----> cpu vt to 1.315

Intel website = VID Voltage Range 0.8500V-1.3625V

Run the ram as slow as possible.
This motherboard has terrible ram divider options and also overclocks poorly with DDR3.
Keep DDR3 speeds as low as possible. Also bring the voltage back down to 1.5 on the ram.

Are you sure you need a NB voltage boost ? I doubt it does until 400 mhz FSB

My g31 has a hole at 383-395 FBS. They are very similar chipsets.
