Bad 512 XMS Module

Recommended Posts

My fourth piece of XMS - No problems till now

Started to randomly get Stop errors (BSOD) like 0X0000005


Found some references on web that said possible Bad RAM

(I thought no way, not XMS )

Ran Memtest 3.2 overnite - 32 runs - 4 failed

System was running at 6-3-3-2

did some searching - found this forum

Found posts on this forum that suggested 6-3-3-2.5 for AMD and voltage of 2.7

Made changes, ran Memtest - failed on third test

Pulled RAM, tried in my DELL Dimension 2400 - Celeron 2.0 P4

No POST - only beeps

Don't have another DDR system to try in.

Would Like RMA

Sticker numbers :

CMX5123200CPT XMS3202v4.2


XMS3200 512MB 400 MHz CL2


If replaced with same - should I still use 6-3-2.5 and 2.7v?

Thank You

Memtest 1.65 also shows errors with 2.5-3-3-6 @2.7volts

Didn't mean to confuse - I only have one module that has failed.


Is memtest86 1.65 more reliable than memtest3.2 ?


Will the replacement RAM need to be set at 2.5-3-3-6 @ 2.7

I have a pair in a ASUS A7N8-Deluxe at 2-3-3-6 @ 2.7

The replacement will probably go back in the A7N8-X

There's 2 memtests out there:


Memtest86+ (http://www.memtest.org/) (this is the one Corsair recommends)

Latest Version: 1.65 (October 1, 2005)


Based on the well-known original memtest86 written by Chris Brady, memtest86+ is a port by some members of the x86-secret team. Our goal is to provide an up-to-date and completly reliable version of this software tool aimed at memory failures detection.


Memtest86 (http://www.memtest86.com/)

Latest Version: 3.2 (November 11, 2004)


Memtest86 is thorough, stand alone memory test for x86 architecture computers. BIOS based memory tests are a quick, cursory check and often miss many of the failures that are detected by Memtest86.
