Warranty Request and some questions

[Nefaste]

I've got a 2.8ghz Pentium 4 system (800mhz FSB), with an Asus P4P800 Deluxe motherboard (which Asus enabled the Intel PAT tech on).

 

For almost two years I've had 2 CMX512-3200C2 (total of 1GB of memory) acting in Dual Channel mode, and decided recently to upgrade to a total of 2GB a memory with the VS1GBKIT400. Then I started having problems, random blue screens, reboots, etc. The STOP messages were coming from a variety of sub systems, so it seemed like it wasn't a specific subsystem failing, so of course I figured it was probably a memory problem since it was the last component I changed. At first I figured it might be one of the new Value Select chips, but nope, after running memtest on each of the 4 chips, 1 chip at a time, it turned out to be one of the CMX512's, as I had multiple failures on test #5 (the other CMX512 tested fine in the SAME slot). So I was wondering if I could send it in for warranty repair.

 

Now, onto a kind of extra credit question. Since I'm combining some higher speed memory (CAS 2 CMX512's, which my system has always detected as 2.5-3-3-6 for some reason) with something a little lower speed (the VS1GBKIT400 at CAS 2.5), I was planning on just letting my system just do "Timing by SPD", but was wondering what they actually should be. I assume 2.5,3,3,6. But I would like a little confirmation if possible. My motherboard supports the following settings:

 

DRAM CAS# Latency: 2.0, 2.5, 3.0

DRAM RAS# Precharge: 2, 3, 4

DRAM RAS# to CAS# Delay: 2, 3, 4

DRAM Precharge Delay: 5, 6, 7, 8

DRAM Burst Length: 4, 8

DRAM Idle Timer: Infinite, 0T, 8T, 16T, 64T, Auto (I just use Auto)

DRAM Refresh Rate: 15.6 uSec, 7.8 uSec, 64uSec, 64T, Auto (just use Auto)

 

Since you don't rate Value Select memory apparently, if I was just using the XMS modules, what would those settings be in theory?

 

Thanks for the help!

You will need to disable PAT and then set the timings to Cass 2.5-3-3-8 and set everything else to AUTO except set the Dim Voltage to 2.8x Volts and then disable legacy USB and test the system with http://www.memtest.org.

Done, errors continue as before. The other CMX512 continues to pass with flying colors. Would you like me to post the specific error messages and memory addresses?
