Memory question

I have a PC with an Intel 865Perl MB. I upgraded it from a Celeron to an
800Mhz 2.6 P4 and I went from 1Gig of mem to 2Gig of mem. No other hardware
or software changes. Ever since the upgrade (6 months ago) I've been having
probelms with the system freezing. I never get a BSOD it just seems to
freeze. It only freezes after a reboot though. Here's the scenarios...

If I reboot the machine it will sometimes freeze, usually within a day, most
likely within hours. If it goes for more than a day it will run for months,
usually with no problems until I reboot again.

I'm thinking that the old memory can't handle the higher bus speed. What
speed DRAM shoul I be using?

The system is running Win2003 Server with Exchange 2003 and SQL Server 2000.
This is a test machine, not production so it's more of a hastle than
anything else. But I do keep my mailbox on that server.

Thanks in advance,
jim
 
When you changed the motherboard did you reformat the harddrive and do a
clean install of the OS's? You were supposed to if you didn't. Otherwise
you get nasty Registry errors.
 
I didn't change the motherboard. I just upgraded the processor and added an
extra gig of memory.

DaveW suggestion about repair-reinstalling Windows after the cpu
change seem like a good idea to me.
Other suggestions: remove some of the ram and see what happens.
Have you considered the PSU? How are your voltages?

But there's also a couple of other comments to make. The 865Perl has
4 slots, and I assume you've filled them all? with 512MB each? Well,
Intel's chipsets does not seem to run brilliantly well at that config.
It's not like it won't work, but it seem to be more sensitive to
individual ram sticks. I guess it's just a matter of trying different,
until it's ok. It will always be slower performance, once you get
above 2 sticks, nothing to do about that, latency takes a penalty with
Intel 865 above two sticks. My guess is that it's something to do with
refresh... mumbo jumbo...;-)

Sometimes when additional memory is added, the timings in the BIOS need to
be slowed down slightly for the system to keep everything in sync. This
only happens occasionally and sometimes is just a quirky result of that one
memory chip with whatever motherboard it happens to be in. It sounds like
you would know how to slow your memory down a little, but if you don't, try
your motherboard manual and do a google search for memory timings. Good
luck.
