Defective CMX256A-3700PT dimm (TWINX512-3700PT)


Recommended Posts

Started getting random abends from games approx 2 weeks ago under heavy loads. Double checked BIOS settings, temp of MB and CPU, video drivers, etc.. all okay.


System config:

Asus P4P800

2.8Ghz (not OC'd)


Ran tests on both TWINX dimms using the following steps:


1) Removed all but dimm (a) and ran memtest86+.. 20 passes without errors.


2) Replaced dimm (a) with dimm (b) in same socket. Numerous errors were detected.


To confirm errors weren't due to dimm sockets:


3) Moved dimm (a) to dimm socket 2 and reran tests - again all successful.


4) Moved dimm (b) to dimm socket 2 and errors occured once again.



If only one dimm of a TWINX pair is bad, do you simply replace the defective dimm, or the entire pair?


Thanks for your help.

If you purchased a Twinx set you should submit the RMA for 1-Twinx set and send both modules.

Please follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!
