system unstable after adding new memory

[Guest]

I have a PC with Asus P4P800 Deluxe board. It runs fine for 1 year. I
added two 512MB memory (Kingmax SuperRAM Series Dual Channel Kit 184-Pin
1GB(512MBx2) DDR PC-3200, Model MPXD42D-2) last night. Initially, the
system would reboot itself after reaching Windows 2000. I increased the
voltage for both CPU and DDR and it ran fine. Things got strange this
morning. With the same setting, it would always reboot without reaching
Windows. I disabled my overclock setting to default and increased the
voltage and it booted to Windows. It would not run anything. Opening a
folder, launch a program would make the PC reboot itself.
Taking the memory out, everything goes to normal. It obviously is the
problem of the memory. I have 2.8 Pentium 4 processor overclocked to 3.3
and now I can't even run with 2.8gb. What is wrong with the memory? Could
it be a faulty one? How well is KingMax? Does it run well with oveclocked
system?
Also I wonder if there is website about the optimal settings for Asus
P4P800 Deluxe that I can use for reference?

Thanks for the help,

cpliu

Could be a borderline PSU, as well.

Would explain the getting worse over time (admittedly a short time).

Try relaxing the timings on the memory and/or underclocking.

RAM isn't inherantly reliable with or without overclocking the CPU, it
depend's on what speed you're actually running the RAM at, as well as
the timings on the RAM.

Thank you all for the suggestions and references. I took the old RAM (one
512MB DDR) out and put the new pair to its location and ran fine for 2
days. I then added the old RAM to other slot and it runs fine too for the
last 2 days. So maybe the new RAM does not like the other slots (the one at
the right side of the board).

I've not tried overclocking yet. I will wait for a few weeks at default
speed before trying.

Best regards,
