I am using a P4PE-X with a P4 2.4GHz 800MHz FSB and one Keton PC3200 DDR
512MB DIMM.
If I run with the default BIOS setting of 2400MHz the machine locks up
intermittently, sometimes not even making it through POST.
The lockups were so bad at BIOS version 1003 (which came on the mobo) that I
could not even get an OS installed. Then I read that I needed 1005 to
support 800MHz FSB, so I installed 1005 and the lockups became much less
frequent, but still enough to be a nuisance.
I found that by switching the CPU speed from AUTO to MANUAL and then
reducing the CPU External Frequency by just a couple notches (ex. from
200MHz down to 198MHz) the system becomes stable. However, I am not
satisfied with this because as I understand it, I must run at the full
200MHz to get the 800MHz FSB speed.
I wonder if this has to do with the RAM I am running. It is not an ASUS
approved part, but it was the only 512MB PC3200 that newegg offered. The
info about approved RAM on ASUS support site does not seem to be accurate
(same part numbers listed for multiple manufacturers). More importantly, I
cannot find an online vendor who sells the approved part numbers.
I have also tried the beta BIOS 1006.001 from the ASUS website with the same
results.
Do you think this is a RAM problem or something else? I run the long POST
and it makes it through the multiple RAM tests every time but once (and that
test locked up - it did not report a parity error or anything like that).
I have no extra cards installed besides the AGP video. I have one HD and two
optical drives. 300W power supply that came with SuperCase. Could the power
supply be inadequate, or if so, would it also fail at the reduced CPU speed?
Any advice appreciated.
THANKS,
