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

If you are still around and reading this thread, would you mind posting what the issue was? C1 POST code indicates detecting memory, and it is apparently not able to detect the memory. I am having a similar situation with POST code at C1 when trying out new Corsair 1024GB PC3200 DIMMs. My 8K5A2+ doesn't seem to like it, though it would seem that PC3200 should be backward compatible with PC2700 which the 8K5A2+ does support.

Was your issue related to memory, and if so how did you resolve it?
