8KNXP & memory issues... HELP!

Thanks for the info. I actually feel stupid now because I found the
cause of the problems. Orginially the PC wouldn't boot, but I triple
checked all wires and found out the 4 Pin power connector for P4's
wasn't fully plugged in. It was about 75% plugged in but not snapped
in place.

That solved all of my issues. I'm now running the XMS memory at the
2-2-2-5 timings and after an hour of CPU stress testing it is working
beautifully. I will run memtest x86 afterwards just to followup.

If you can get your money back on the RAM you've already purchased, try
Kingston KVR400X64C3A/512, which is what I'm running (2 x 512mb modules) on
my 8KNXP with no issues. You can buy a matched pair at a good price at

from the bottom [KVR400X64C3AK2/1G ]). YMMV, but it might be a good option
to try.

You're not alone having trouble with RAM compatibility on this board.
Regardless of what you do, please let us know how you make out.

Oooh, nice.

I'll have to give that a try. I must admit that I have been meaning to
change my timings to some more aggressive settings, but I wanted to
check the machine was 101% stable first.

I definately have some good news regarding that situation. I came to
find out that the non-booting and instability issues at first were not
memory related, but rather power related. That 4 pin power connector
that feeds current directly to the CPU wasn't inserted all the way due
to a broke clip. Anyway once I fixed that everything worked.

I went ahead using my Corsair XMS CMX512 sticks in dual memory mode
and it worked absolutely perfect. I have been able to even use those
sticks RELIABLY at 2-5-2-2 timings when they are detected and
recommended as 2.5-8-3-3. I even ran memtest x86 on the most
agressive timings and even after hours of testing 0 errors were
reported. With Sandra2003 here are my scores with the various
timings:

2.5 - 8 - 3 - 3 = 4677/4665
2.0 - 7 - 2 - 2 = 4720/4724
2.0 - 6 - 2 - 2 = 4731/4738
2.0 - 5 - 2 - 2 = 4759/4734

Amazingly the system is absolutely rock solid. I thought I got the
good end of a bargain when I only paid $100 for the XMS memory which
is rated for 2.5-8-3-3 speeds and I am able to run it at full
agressive settings.

For my first time on Corsair, i'm hooked.
