System unstable after adding memory

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

Try relaxing the RAM timings. It sounds like a problem I had when I
tried to run the RAM too fast.

Are you using more than two DIMMS or more?You might have to run CAS 2.5 or
even CAS 3.Set it in the BIOS.Did you check if your mobo will run 3 modules
at 400 FSB? Some will only run 3 DIMMS at 333 FSB if they are double sided.

Test with memtest86. Make sure you run the test first with the two 512s, if
you see problems, then run singly to determine the bad one. I doubt you got
two bad modules, but it does happen. As far as dual channel goes, I never
buy the so-called "matched" sets. I just get two sticks of good quality ram
with the same part#. Lately I have been having very good luck with Samsung.
I haven't tried any of KingMax stuff. Crucial has always been good too.

It was in auto mode and it ran at 320(?) instead of 400.

Thank you all for the suggestions. 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,

cpliu

I have total 3, 512MB for each. I will check the BIOS.

Thanks for the suggestion.
