P42M-P25 MSi Intel

Hi, I have a p41m-p25 MSi mobo with a intel e8400 dual core chip. Stock speed is 3.0 Ghz. The best overclock I can get is 3.204 Ghz before it wont boot. Memory is ddr3 1333 4Gb.MSi GT 630 pci-e 4Gb graphics card. Zalman CPNS5X air cooler and a X-Viper 750w power supply.
The only setting that are stable are:
CPU FSB 356
CPU Ratio 9 3204Ghz(3000Ghz)
Dram 1139 (1333)
PCi 105 (100)
CPU V 1.250 (1.850)
NB. auto
CPU VTT. auto

Stock in brackets.

any alterations ie PCi 105 to 106, no boot. I have tried lowering the multiplier in stages, 9,8,7,6 and increasing the FSB to no avail.

Anybody have any ideas? Also the system will not recover from S3 shutdown. Seems to boot but no video, even on stock settings with old power supply and Nvidia 8600GT Graphics card

Many thanks

Mike

You are going to have to raise the NB voltage and Vtt a bit as you increase the FSB. Also, leave the PCIe at 100.

We have a guide here for this generation CPU in the Ultimate Sticky thread in this section, let me find it and link it...: http://www.overclockers.com/forums/showthread.php?t=515316

Many thanks, will read the thread.
