Please Help, Bad module(s)?

System Specs:

 

Mobo: Epox 9nda3

CPU: AMD Athlon 64 3000+ Socket 939

Graphics Card: PNY 256 mb Geforce 6800 GT

 

Ram: Matched Pair TwinXL Pro(w/ leds) 2x512 MB 400mhz

Part # CMX512-3200xlpro

 

Ever since building this system 2 months ago I have been receiving BSODs and random game crashes in World of Warcraft and Counter Strike Source. I refused to believe it was the RAM causing the problem since it was a brand new matched pair from Corsair, however after running memtest86 I received several errors. I have played around with various bios settings and video card drivers for the past 2 months to no avail so I am pretty sure it is the RAM after all now. Any last suggestions or can I possibly send these in for a replacement?

CAS Latency: 2

RAS to CAS Delay (tRCD): 2

Row Precharge (tRP): 2

Active to Precharge Delay (tRAS): 5

Memory voltage: 2.7x or 2.8 volts

All other settings to default.

 

Test one stick at a time in each slot. In your original test, how many errors in each test? If errors occur in the new tests, the same info will be needed.

I ran a few tests...

Stick "A" Dimm Slot 1: 2 passes w/ no errors

Stick "B" Dimm Slot 1: 2 passes w/ no errors

 

Stick "A" Dimm Slot 1 w/ Stick "B" Dimm Slot 2: Multiple Errors on 1st pass

 

Stick "A" Dimm Slot 1 w/ Stick "B" Dimm Slot 3: 1 pass w/ no errors

 

I had been running the sticks in slots 1&2 or 3&4 as my mobo manual suggests that to obtain "best memory performance", however in both those postitions I was recieving the BSOD and various random in-game crashes.

 

I will try out this new configuartion for a while(Slot 1&3) and report back with my findings.

Please make sure the Dim Voltage is set to 2.8 Volts and test the system with http://www.memtest.org, but if the modules both test with no problems one up but you get errors when in dual channel that would suggest a power problem or a failing memory controller in the CPU.
