Bad Memory CMX512-3200XLPT

[doueng]

Around a year ago I purchased 2 TWINX 1GB kits for a total of 2 GB. They are both the matching Corsair TWINX CMX512-3200XLPT (XMS3200 512MB 400MHz 2.2.2.5). All four memory sticks are identical. About 2 months ago the systems started to Blue Screen with memory errors. After running diagnostics on my Asus MB, 3.2 Ghz processor, and other components and not getting any errors, I downloaded the Memtest86+ utility and made a bootable CD.

 

I have run the following tests with Memtest-

 

1st Test - Excessive errors on slots 1 & 3, no errors from 2 & 4

2nd test - Swapped memory pairs 1-2 and 3-4, etc and reran the test. Now getting excessive errors on slots 2 & 4.

3rd Test - Took out matching memory that was giving errors in both test and reran memtest. Now not getting any errors with memory in slots 1 & 3.

4th Test - Placed only the apparent faulty memory back in slots 1 & 3 and reran the test. Excessive errors again.

5th Test - Placed 2 bad modules in another similar machine and received excessive errors again in memtest.

 

It has now been almost 60 days of just running with 1 GB and the two modules out of my main machine and it has not blue screened at all. The machine has been rock solid. I am not overclocking and the memory settings are set to the recommended settings for the MB / Memory combination. There was also no changes to the system in the months leading up to the blue screens and it is back to stable again with the two modules removed.

 

Any other ideas before I request an RMA?

 

Thanks-

Please set the Dim Voltage to 2.75 volts and then set the timings manually to the tested settings for the specific module you have (Cass 2-3-2-6 with the Rass to Cass set to "3"), and then test the module/modules one at a time with www.memtest.org! If you still 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! However, if you get errors with both modules that would suggest some other problem and I would test them in another system or MB to be sure. In addition, with this MB you have to disable legacy USB in the bios when running any memory test. With all four modules installed I would suggest the memory voltage be set to 2.85 Volts.
