Trayal Posted December 4, 2004 Share Posted December 4, 2004 Greetings! I have been having system instability for the last few months and have been having a hard time nailing it down. Today, I searched for memory testers because everything else has been ruled out of the equation. I am using two stick of CMX512RE-3500LLPT - they did not come as a matched pair, but were purchased separately. My motherboard is an ASUS SK8V, and the processor is an Opteron 146 (2GHz). The system is running stock, with exception that the ram is underclocked and running at 400MHz instead of the rated 433MHz. I verified timings are correctly set by SPD. Voltages tested at were from 2.6 to 2.8. Anyway, I tested with the latest memtest86, and also with microsoft's memory tester. I tested the memory with both sticks installed, then individually to narrow down which stick was the problem. One stick runs fine every time, but on the other stick, both tests found numerous errors. memtest found errors on test 5 and 8, and the MS test found errors on LRAND and ERAND. The errors always occur at a consistent memory address (though this address changes everytime i switch the location of the problem DIMM) After looking through the forums here for other things to check on, I disabled legacy USB support, with no percievable change. Also, it doesn't matter what slot the bad stick is in, it always throws up errors - so motherboard is not the culprit. --- EDIT: Tested with ECC both on and off. On just decreases the number of errors a small ammount. --- Is there anything else I can do to test at this point, or should I request an RMA? Thanks for your time!
