CMX1024-3200C2PT Bad?

[BankerBob]

I have purchased multiple sets of Corsair memory because of the quality and support. This is my first problem and first post. The PC that I built for my son locked up after about 6 months. The first problem was a bad PSU (squirrelly +5v rail); replaced. The second problem appears to be one of the Corsair CMX1024-3200C2PT pair. I’ve read many RAM GUY discussions and recommendations.

 

FIRST MEMORY TEST: I used my own PC (see PC Specs pull-down) to run memtest86+ v1.65; made no change in memory timings for this test. I received a few hundred errors on Stick 1, but memtest tossed >100,000 errors on Stick 2 before test 6 of the first cycle was completed.

 

PC SPECS:

ASUS A8N-SLI Deluxe Rev 1.02

AMD Athlon 64 X2 4400+ Toledo

New Enermax FMA II 460W (verified stable with Coolmax PS-224 tester)

Corsair XMS CMX1024-3200C2PT pair, 2GB

e-GeForce 6600GT 128MB

WD Raptor 74 Sata

WD Caviar SE16 WD250KS Sata

 

FINAL MEMORY TEST: With the memory in my son’s PC (specs above), I followed the RAM GUY’s instructions for memory testing. Here are the settings and results:

- BIOS - Has been running the latest v1016

- BIOS - Loaded setup defaults

- BIOS - Set Dimm voltage to 2.7v

- BIOS - Disabled legacy USB support

- BIOS - Set memory timings to 2.5-3-3-6-2T (default was 3-3-3-8-2T)

- Ran memtest86+ v1.65 for each stick separately using correct slot B1

- Stick 1 was perfect after 17 cycles (7 hours), so the errors in my first test were apparently related to timing.

- Stick 2 would not even boot in the same B1 slot to allow memtest to run, so the 100,000+ errors in my first test appear valid. The system speaker throws continuous sets of 1-long-beep-2-short-beeps.

 

The memory was purchased as a matched pair from newegg. If the one stick is bad, will the matched pair be replaced?

 

Excellent support site! Thanks for your help in resolving this problem.
