I recently upgraded my CPU from a 1000 TBIRD to a 2600XP 266FSB. I a have an ASUS ATA266 Motherboard wih 512 PC2100 Ram. According to ASUS website as long as I have rev # 1.10 Board and current Bios 1012.001 or higher it should work. The problem is I can only get the system to run if the clock speed is set to 1600 insted of 2133. When I set to the default clock speed 2133 in the bios and restart the sytem, It post and brings me back to the bios saying incorrect clock speed. Can someone help me out here? It sucks to only get 1.6 ghz when I should get 2.13

Set the processor frequency by DIPs and NOT by the BIOS. Just disable Jumper Free (JEN) and set the DIPs to 133MHz FSB. This should work.
Tried the Jumper mode and switches with little success. Went back to the bios and set it to manual. Got the system to boot with a Mulplier setting and Frequency of 132/44. It reads as as 2.13gig and 266FSB when booted but system seems a little unstable. Is this wrong to set it like this? It should boot with the default setting but doesn't. When I set the frequesncy to 133/33 it will not boot. I am running a POWMAX 300 Watt power supply. Can that be the problem? An Asus tech says it might be the problem. My 12V rail is at 15A and he says that is boarderline. After all I was only running a 1GIG TBird before.

It is not good to boot w/ a frequency of 44MHz PCI. What's your Heatsink and Fan (It might be the problem)? And try to boot w/ minimum of components necessary (CPU, MOBO, VIDEO CARD, MEMORY, HD, HSF) to test the PS.
POWMAX is a very low quality power supply (as opposed to Power Man, a very high quality power supply). I can't garuntee this is your problem, but it sounds like a good place to start.

I have an antec 430W on the way to be on the safe side, I can always use the extra juice!! I will post the results once I get it.
