Here is my basic system loadout:

800 PIII PC 100 running on BX-133 RAID
2 UDMA Maxtor 7200 40 gigs rinning in RAID
Generic case, average cooling, 250W
256 megs PC 133
Voodoo Banshee 16 meg
-64 Meg Prophet II GTS Pro in the mail
Sound Blaster Live Platinum
-LiveDrive 5 1/4" Bay Audio Panel
Generic CD-ROM
Ricoh 6x ReWriter
Generic 12x DVD
Aopen 56k modem

All running in a generic case with average cooling. I dont think it is an issue with heat, but my computer simply wont overclock one bit. I have no problems whatsoever running at 800 PC 100, but the reason I bought all my other equipment at 133 was because I was expecting to jump it up to 133 and at the same time give it some more horsepower. When I do this, even slightly, the computer completely fails to turn on (It physically turns on but there is no signal to the monitor). The only way I can get it back is by resetting the BIOS (The BX-133 uses a bios software overclock). There are two things that I pray are what hold it up from being overlcocked: My video card (a 16 meg banshee, soon to be a very good one) which, if it is a problem, will be out of the way very soon. And my power supply, 250 watts. This is probably the problem, but I am not sure and dont want to buy a new one until someone confirms this. I know others who have overclocked thier PIII just fine on a 250 watt (sometimed two or three hundred mhz) power supply, but I might be because of all my peripherals that I need more. In any case, until I can get some diagnosis, or maybe a way to solve the problem without me having to buy a new power supply, I will wait until my vid card arrives and see what happens. Please let me know if there is anything I can do, whether purchase a new power supply or not.

cheers,

Make sure that your AGP divider is at 2/3 and the PCI divider is at 1/4.

Also, if you are running at AGP 4x, try 2x....

If you are running the ram at CAS2, you may
want to try it at CAS3.

If none of that helps, I'd go for a 300w power supply.

I wouldnt run my pci divider at 1/3 at 133mhz 1/4 is the setting you want. 1/3 divider will f you up over 120fsb.
