I purchased a PIII 800/100bus SECC2 Slot 1 for my Asus P2B-DS. I downloaded the current bios and used the asus flash update, rebooted, shows the new bios at startup and runs fine with my PII 450.
I removed cpu and put in the 800 PIII which is also SECC2 instead of SEC like the PII but fits fine. I set the jumpers to use the 8x multiple with a 100 bus.
Start machine and only the power fan runs, nothing else runs...shut down system and converted back to the 450 PII..everything is ok.
Please help me if possible as i'm getting frustrated. Is it possible the cpu voltage isn't set correctly? if so how do i change it.
Thank you!

  1. The voltage is greater on the older CPUs, but since I don't have that board, I don't know whether it's possible to change it. I wouln't put your coppermine cpu back in until you find out for sure.

    I did look around the Asus web site out of curosity and see that only certain, later versions of your board will support an secc2 copermine: <A HREF="http://www.asus.com/products/techref/Cpu/Coppermine/index.html" target="_new">http://www.asus.com/products/techref/Cpu/Coppermine/index.html</A>.

    Not sure whether this helps or that you already know this.
