P4R800-VM Spontaneous Rebooting

[DC]

Archived from groups: alt.comp.periphs.mainboard.asus,alt.comp.periphs.mainboards.asus (More info?)

I have a Celeron D 2.6 GHz, which has a 533 MHz FSB, mounted to an
Asus P4R800-VM. I am experiencing random spontaneous rebooting. The
system otherwise appears to run well.

I suspect the problem is due to the RAM/FSB mismatch. When I
purchased the components I grudgingly agreed to the salesman's
suggestions that I use dual channel PC3200 400 MHz DDRs rather than
the more expensive PC2100 266 MHz DDRs. I'm since come to question
the validity of a lot of what that salesman had to say.

Anyone have any real knowledge of this situation before I bring the
RAM back? Will a RAM speed and CPU FSB mismatch cause a problem like
this with this board?

thanks

That memory setup shouldn't be a problem, I can't see any reason why
you'd want/need to run PC2100 memory on that system.

Have you tried running Memtest86 on it? That would probably help nail
down if it was a RAM problem.

However, RAM problems don't tend to cause system reboots - I would be
more likely to suspect the power supply for example..

Manually set the memory speed in BIOS to PC2700/DDR333 - not auto.
Check the memory to see if it is seated in the proper slots (A1,B1) for dual
channel.

There are only two DDR slots in the board, and I don't believe there is any
such memory speed setting in the BIOS... the speed is reported, but you
cannot adjust it... I'll double check though.

My mistake, there are four DDR slots; however the PC3200 DIMMs are in the
proper A1 and B1 (blue) channels.

I have also double checked the BIOS and confirmed there is no setting to
adjust the memory speed from auto to any manual configuration.

It's a brand-new 400 watt PSU... I guess I can swap in another one but
somehow I doubt it is the problem. I've come across a number of posts
about post and reboot problems with this board in Usenet and they mostly
seem memory related. I could be wrong.
