I have an Intel D845PESV, works fine with 2.3 celeron. The compatibility guide on the website lists a 2.8 533fsb 512k l2 cache chip.

http://developer.intel.com/design/ [...] v_proc.htm

Somehow I missed the cache because I ordered a 2.8a 533fsb 1m l2 cache.

When the new chip is installed the motherboard does not even get to BIOS. Does having too much cache availiable cause a hardware incompatability?

1) is the bios flashed to the lastest level?
2) did u try resetting the CMOS ?
3) Any other jumper you have to do on an intel board?

The loving are the daring!

The voltage requirements for prescott are much higher than for northwood chips. The board may not be able to deliver that much power.

There's no such thing as "too much cache". There is such a thing as "too much power", as in the Prescotts draw around 30% more power than the CPU's your board was designed to support.
