8k5a2+ CPU Upgrade problem

[PorPorMe]

Mobo: Epox 8k5a2+ Newest official bios (2003) Will support up to XP2800+
Purchased XP2400+ ( AXDA2400DKV3C) It wouldn't boot.
I assumed the last CPU was bad because 1 pin was missing on a corner that wasn't a reference corner. RMA'd it back.
New CPU does the samething as the last.
On power up,CPU fan starts-post code goes to C1 (which I have no reference in my book) and then mobo speaker starts to beeb and CPU fan shuts down. Beeping continues for a few seconds even after all power is shut off.
1200 put back in and it boots right back up.
Any ideas would be helpful.
Yes cmos was cleared

Don't bother responding-figured it out myself. It would have been nice to have some help from those that know more than me. Oh well
