memory parity

[DiDi]

Memory parity system halted on startup. What is failing in this old (9 year old) Dell
XPST 450. I would like to backup all data. Then start Win 98se all over clean and go
on from there. But ....over the past year, before I got my new machine. Every once
in a while I get Memory Parity detected, system halted. Then I reboot and everything
is ok. Any ideas for next steps?

Open the case and check your RAM

make sure the connections are good and clean.

Try reseating it.

Also run a RAM test such as memtest86

Re: memory parity

I vaguely remember that when I added my last stick of Ram it was higher than the one
before it. Someone told me I should have switched the places of those two so that the
highest came first and then the lower. Can I switch them now or just clean them and
seat them? I ran a memory check a couple of months ago and it was ok and this has
been going on for over a year. Do I still have to do another one?

Just because the RAM passed a test...
there still could be a problem.

I don't know if it will make any difference switching the sticks
around...you can try it if you want.

I'd run it on just your original stick for a while and see what happens...

If no problems , then just try it on the newer stick.


The problem could be with one of them...
or the problem could be they simply are not compatable with each other

Re: memory parity

I guess that means there definitely is a problem. I'll get to work. Thank you ,

OK

I'd probably just run it on one stick at a time
and see what happens

Re: memory parity

The memory parity error is a hardware failure somewhere in the memory (RAM)
system. It's not unusual for memory to be a bit flaky when it's cold, and
then operate perfectly when everything is warmed up - it might not even be
due to the memory, but other components (such as a power supply) that need
to be warmed up a bit to run properly. If the problem is only occurring at
first startup then you can probably live with it by letting the machine run
for a while before starting to boot, but if it starts happening when you are
using the machine you will have to address the problem. Note that an error
caused by cold components is probably not going to show up in a RAM testing
program - by the time you get the program up and running things are warmed
up enough for the problem to disappear.

If you're wondering how to do that: press the Pause key at some point
early in the boot process, then the enter key (which cancels the Pause
key) when you decide it's had long enough.
