Did you try 1 stick in slot 0 by itself? Usually the slots are
numbered. You may need to insert them into slots 0 and 2,
skipping one slot. But I would try the single one first in slot
0. Is your memory unbuffered non-ECC?
I'm having spontaneous reboots with an hp machine as well as other
errors, but I'm using 1 gb DDR. Everything was fine until I added
the 1 gb chip to the 3 x 512mb already installed.
Specs from HP for your motherboard:
* Dual-channel memory architecture
* 4 x 240-pin DIMM sockets support unbuffered non-ECC 4 GB
533/400 MHZ DDR2 memory modules
* Maximum HP/Compaq approved memory is 4 GB*
