Bad XMS 3200XLPRO Chips??

[nkelly182]

I have a pair of CMX512-3200XLPRO that I have been running for close to a year and a half without issue. I had not changed hardware in about 6 months. About three months ago I started crashing and began troubleshooting. When I set the motherboard not to reboot on errors it gave me memory reference errors. As a test, I replaced the memory sticks with two other memory chips that I had laying around and I was able to operate without any issues. I have been slack and just left it running like this for about three months without any issues.

 

As a test I put the chips back into my machine again last night and started getting errors again. Memory reference errors and such. I have the same settings that I used for the year and a half without issue - memory = SPD & voltage = 2.8. (ASUS A7N8X Deluxe mobo)

 

I strongly suspect one of the match chips set is bad. What do I need to do to get an RMA for these?

 

Thanks,

Can you tell me the bios settings you have set for both CPU and memory and any performance settings that you may have set?

[nkelly182]

Settings are as follows:

 

CPU Freq - 133Mhz

CPU - Auto

System Performance - Optimal (stable)

Mem Freq - By SPD

CPU VCore - 1.650V

DDR Volts - 2.80

Please try these settings and test them one at a time with http://www.memtest.org.

System Performance: User Define

CPU Freq: 133 MHz

Memory Frequency: 100%

Dim Voltage to 2.8 Volts

Resulting Frequency: 133 MHz

Memory timings: Manual

Would results in these settings

SDRAM CAS Latency: 2.0T

SDRAM RAS to CAS Delay (tRCD): 2T

SDRAM Row Precharge (tRP): 2T

SDRAM Active to Precharge Delay (tRAS): 5T

Graphics Aperture Size is 128 MB

 

If you have a failing module they will still fail at these settings, but if its just a bottleneck in the chipset the errors will go away.
