Faulty memory module

[dmuino]

I have 2xCMX512-2700C2 using a VIA KM266 chipset and I was getting some random file system corruption. I ran memtest86+ with both modules connected and I got an error. In order to diagnose which of the two modules was faulty I took one module out and ran the test (first one was fine) then did the same thing with the other and got a memtest86+ failure.

 

During the tests I used the same slot in the motherboard to isolate a possible motherboard problem. The error basically says that it tried to write FFFF FFFF but got FFFF FFBF (error bits 0000 0040) at address 0162b6134 (354.3MB)

 

This is reproduceable.

Please set the Dim Voltage to 2.7X volts (+.2 Volts W/Giga-Byte) and then set the timings manually to the tested settings for the specific module you have, XMS2700C2 Cass 2-3-3-6 for example or if you have Value Select "BY SPD" and then test the module/'s 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.

I still got the same error after trying those settings - tried with the manual timing values you specified and with By Spd.

 

I get the error on one module. The other module passes the tests.

 

I'll follow the link in your signature to see what the next steps are.

 

Thanks for your help.
