PIII 600 keeps crashing -- help!

[cwand]

I purchased a pre-tested combo from OutsideLoop because it wasn't any more expensive than purchasing the components seperately and not having the "guarantee". It's a PIII 600 and ran stable for them at 150fsb 900mhz@1.75v. I'm running it at 133fsb 800mzh@1.65v and having nothing but problems.

It constantly crashes to the "blue" screen and crashes to the desktop when I try to launch a game. I have to reboot frequently. I can get it to run a game okay, but usually have to try a few times.

I have all high-end components. (i.e. Geforce2 GTS 64mb, Mushkin rev.2 ram, etc.) I have tried running it at higher bus speeds and the problems stay the same, they don't get worse like I would expect. BTW, I have a modded Addtronics 7896 with 7 fans, so cooling shouldn't be an issue.

Does anyone have any suggestions?

What motherboard do you have?

 

[Chuffmaster2k]

Seven fans? What kind of power supply are you using? Have you tried putting the voltage back at 1.75? More details are needed. You have latest bios for motherboard? Good luck.

I have the Enermax 450W power supply.

Motherboard is Asus P3V4X with original BIOS.

Have changed voltage and still experience same problems.

how about at stock speed does that create any problem. Also at 150FSB 1.75V is it stable? go wonder?

Put a heatsink on the ICS clock generator chip located at the bottom of the 4th DIMM slot. That always increases stability on overclocked P3V4X's since the clock generator runs very hot.

and after you mount a heatsink over that chip, see if you can mount one of your fans to blow directly on to it.
