@lazibayer, I've tried clearing the CMOS already. I don't have a BIOS reader/flasher either (will probably save up to get one).
@luckybob, ok this is interesting. HP supports ECC and non-ECC RDRAM. I'm reading the HP Kayak XM600 manual and it appears that even though there are 3 RIMM slots, only 2 RDRAM modules are supported. The last slot must be a terminator module called CTRIMM. The continuity module that I'm used to seeing is the CRIMM. I did not know the CTRIMM existed. And not having much luck on eBay finding one... lots of sellers calling CRIMM as terminators.
I've definitely tried 1x PC800 RDRAM with 2x CRIMM and it doesn't POST either.
Edit:
Another possibility is that it only takes 133 FSB CPU's.
This thread below states that CRIMM's or 3x RDRAM RIMM's should work.
