Mac99 Posted October 15, 2009 Share Posted October 15, 2009 I have two packs of TWIN2X4096-8500C5D, 8GB total. One of the sticks failed today, producing thousands of errors with Memtest86+ I already started the RMA process but I have no idea how to identfy the module that belongs to the defective one. All 4 sticks are Version 2.1, all are from the same lot and there's no serial number on the label except a bar code which I can't read. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 15, 2009 Corsair Employees Share Posted October 15, 2009 With 4 modules I would suggest setting the memory frequency at DDR667 or DDR800 and set the memory Voltage to 2.1 Volts and set the NB/MCH/SPP Voltage to +.2 Volts as well and test the system with http://www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test. And you can tell which modules are matched by the lot code.

Mac99 Posted October 16, 2009 Author Share Posted October 16, 2009 Did you actually read what I wrote? The 4 RAMs all have the SAME lot code! Any other suggestions how to identify the module that belongs to the defecive one? As for the frequency suggestions: Until yesterday all 4 worked at DDR1066 with 2.1 volts at 5-5-5-15 2T timings. However, after working problem free for several hours they failed and produced thousands of errors. Powering down the system for a few seconds immediately resolved the problem. After that they worked again for some time before failing again. Lowering speed to DDR800 did NOT help with that problem. I've already posted that problem here a while ago but never got a reply from you. Yesterday one stick failed completely. I tested the Modules seperately and in all possible combinations with Memtest86+ 4.0. One stick failed at both DDR1066 and DDR800, producing already thousands of errors after less than 10% of Memtest. The other three sticks passed without errors. I don't know if the previous problem was caused by that faulty module too as the computer wasn't on long enough after removing the defective module. I started the RMA process but I don't know which other Module belongs to the defective one as all four have the same lot code. Link to comment Share on other sites More sharing options...
Mac99 Posted October 20, 2009 Author Share Posted October 20, 2009 No more suggestions on how to identify the TwinX pairs? Link to comment Share on other sites More sharing options...
Wired Posted October 20, 2009 Share Posted October 20, 2009 If the labels are identical then there's no way to identify the pairs. Just pick a mate for it and send it in. Link to comment Share on other sites More sharing options...
