Autarkh Posted February 14, 2005 Share Posted February 14, 2005 I have two DDR400 DIMMs which were bought as part of a TwinX matched memory pair. The stickers read as follows: CMX512-3200LLPT XMS3205v1.1 0303006 XMS3200 512MB 400MHz 2226-T1 I am currently running them in a Gigabyte SINXP-1394 motherboard in dual channel, single 128-bit mode at stock FSB (133) and default voltage. The timings are 2-7-2-2, though I also experience problems at 2-7-3-3 and 2.5-7-3-3 (system/apps hang, error messages, BSOD when running Windows, CTDs, reboots, etc). None of these issues occur when using known good Corsair and Samsung modules from different boxes and the instability persists when the suspect DIMMs are used on other machines. One of the modules consistently fails the various tests that are part of the MemTest86 1.27 suite. The errors seem to be concentrated around 255.8 MB when it is used by itself, and 511.6MB when used with the other module in dual channel mode. As far as I could tell, I did not have any problems on the tests that I ran with the second DIMM, but as they were bought as part of a matched TwinX pair I'd like to be able to return both for testing and/or replacement. Thanks in advance for your time and prompt attention. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted February 15, 2005 Corsair Employees Share Posted February 15, 2005 Please make sure the memory Frequency is set to DDR333 and set the Dim Voltage to 2.7 Volts or +.2 Volts with Dim Over Voltage control and then test the suspect module. And I would set the Rass to Cass to "3' as well. Link to comment Share on other sites More sharing options...
Autarkh Posted February 15, 2005 Author Share Posted February 15, 2005 Please make sure the memory Frequency is set to DDR333 and set the Dim Voltage to 2.7 Volts or +.2 Volts with Dim Over Voltage control and then test the suspect module. And I would set the Rass to Cass to "3' as well. It took a while, but I tried a combination of things... Using the increased voltage, I experimented with both DDR400 (which it has been running for nearly two years without any problems) and DDR333 with the timings you suggested, but I still get errors when running memtest (incidentally, they occur around the same memory address). I also tried the subjective test of using the computer for a couple of hours and saw no improvement in stability. Link to comment Share on other sites More sharing options...
