Bad CMX512-3200C2

I started having problems with an application crashing to desktop. After updating all video, mb, sound and network drivers, I was still having the problem. I downloaded memtest86 and found that I had memory errors. I replaced the two memory modules with new DDR400 memory and had no problems with the application crashing and memtest did not report any errors. I then tested each module alone and found that one module produced the errors in memtest86.

 

My system:

Asus P4C800 Deluxe

ATI Radeo 9800 Pro

(2) Corsair CMX512-3200C2

Ram settings according to memtest:

199 mhz (DDR398) / CAS: 2.5-3-3-8 / Dual Channel (128 bits)

 

I did not make any manual changes to these settings. They are the default settings. I would like to know if I can get a replacement module.

 

Thanks,

Jason

Please try and set the Dim Voltage to 2.75 Volts and test the modules one at a time with the following settings.

CPU Freq: 200 MHz

Memory Frequency: 100%/DDR400

Dim Voltage to 2.75 Volts

Resulting Frequency: 200MHz/DDR400

SDRAM CAS Latency: 2T

SDRAM RAS to CAS Delay (tRCD): 3T

SDRAM Row Precharge (tRP): 3T

SDRAM Active to Precharge Delay (tRAS): 6T

Then please test them one at a time with http://www.memtest.org. If you get errors please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!

I downloaded memtest v1.52 and made the timing adjustments as requested. Memtest reported these settings:

Ram Settings: 199 mhz (DDR398) / CAS: 2-3-3-6 / Single Channel

FSB: 199 mhz

 

I believe I entered them correctly from what you suggested. I still received errors from the module in question. Test #5 produced 13,239 errors and Test #7 produced 1064 errors. I did not let the test complete since so many errors were already found.

 

Do you have more suggestions or does the module need replaced?

 

Thanks,

Jason
