Bostoneo Posted March 15, 2005 Share Posted March 15, 2005 I have recently found out that one of my memory modules must of been defective after normal use (no overclocking). I bought 2 Corsair CMX512-3200C2 memory modules on 2/15/05 from http://www.zipzoomfly.com and have the invoice for proof of purchase. The memory module seemed to work fine with dual channel configuration with its partner stick till March 10th 2005. I was in the middle of a game and my PC just powered off automatically. I would try to power up my PC but it would not give video image and the harddrive LED case light would stay lit. After awhile the POST would start coming up and then shortly after, 1 to 15 seconds the PC would power off by itself. After much troubleshooting into replacing just about every part in my system with known working parts and vice versa I found it to be this 1 stick of RAM. When this stick of ram is inserted into ANY RAM slot the PC will malfunction and power off. This is true with my other working PC system as well and will fail to go past POST and shut off or remain in a blank black screen idle state till powered down. I have also put my past 2 sticks of 512Mb ddr400 memory modules in the exact same configuration as the Corsair sticks and the PC performed without any flaws. In short this memory module is bad/defective and has been tested on 2 different PC systems and result in the same problem with the PC shutting down or remaining in an idle state after POST. The 1 stick worked fine for awhile then I guess died. I would like to request an RMA replacement for the 1 stick of memory. The other appears to be working fine.

Bostoneo Posted March 15, 2005 Author Share Posted March 15, 2005 Set all the following you said in BIOS and ran the MEM86 test on the known working corsair module and it passed the test 2x after your post with the specified bios settings and memtest settings. It also passed that test yesterday 9 times w/o flaw. The bad stick prevented the system from booting even after specified bios settings and also tried default settings and wouldn't boot as well. The stick has to be bad considering I have an identical stick that works fine. Link to comment Share on other sites More sharing options...

Bostoneo Posted March 16, 2005 Author Share Posted March 16, 2005 RAMGUY: do I need to include an invoice or anything rather than the stick of RAM (non-twinix) in the shipment? I couldn't find anything regarding that in the site. Link to comment Share on other sites More sharing options...
