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!

Wired Posted December 5, 2004 Share Posted December 5, 2004 This the same memory that you posted here 8 months ago? http://houseofhelp.com/v3/showthread.php?t=24288 Link to comment Share on other sites More sharing options...
Trayal Posted December 5, 2004 Author Share Posted December 5, 2004 Yes, it is the same memory. It retested fine at that time following the suggestion in the response, which is why it took me awhile to consider the ram as the culprit in this case.

Trayal Posted September 28, 2007 Author Share Posted September 28, 2007 Okay, I know this is a very very old post - but it doesn't hurt to check, right? I still have the bad stick of memory I described in the first post. I did originally submit for an RMA and got the number - however, a series of events prevented me from sending in the memory... school (which prevented me from being able to afford the computer down time that would have been required to send in both sticks - matched pair), marriage, and several moves, which resulted in the package being packed away and stored for awhile. I have now found the bad stick. Would it be possible for me to re-submit for a replacement, for the bad stick and also for the still working good stick so as to keep a matched pair? Thanks for consideration Link to comment Share on other sites More sharing options...

Trayal Posted October 10, 2007 Author Share Posted October 10, 2007 I called the phone number as suggested above, and got a case setup, quick and easy. However, after the case confirmation email, I have not heard anything... it's been almost two weeks now. I sent a followup email to the address rma@corsairmemory.com asking for further status or information a week ago, but again I have heard nothing in response. What do I need to do to get this ball rolling? Thanks. Link to comment Share on other sites More sharing options...

Trayal Posted December 19, 2007 Author Share Posted December 19, 2007 Okay... I'm less than thrilled about how this all worked out. It took three months to get an RMA request through your system, but finally I got the RMA number. I sent in 2x cmx512re-3500llpt sticks, and received in return 2x cmx512re-3200ll rev. 1.1 sticks. One of the replacements works well, but the other is bad... I'm back to where I started - half the memory at half the bandwidth, - except this time I have pc3200 rated modules instead of the pc3500 I originally paid a premium for. If they both worked it wouldn't be a big deal... in fact i was pleasantly surprised at first that you still had some of the low latency stuff on hand at all... but, at this point it feels like a raw deal. I have done all the requisite testing... memtest86 of both modules individually in all slots (one is good in all slots, one is bad in all slots), increasing voltage to 2.7, turning on ECC correction, relaxing timings, lowering clock... no go. One stick works at full speed with none of the relaxed timings or ECC overhead, while the other will not work even with all the handicaps listed above. Do I have any options at this point, or am I SOL? And, if I am able to do another return, will I need to send in both sticks and have an unusable computer again, or will I be able to only send in one this time? Thanks for your time.
