RobAJ Posted October 14, 2007 Author Share Posted October 14, 2007 Memory: TWIN2X2048-6400 Processor: Intel Core 2 Duo E6300 Motherboard: ABIT IP35 Pro Graphics Card: Nvidia Geforce 8800GTS PSU: Enermax Liberty 500W SPD settings set manually: 5-5-5-12, with command rate: 2T Voltage: 1.9v I have had the memory for around a year now, originally used on the same configuration as described here but with a Gigabyte GA_965P_DS3 motherboard and a HIS ATI Radeon X1900 GT graphics card. I experienced regular graphics card crashes during 3D games (where the card would often manage to reboot without the whole computer crashing), however upon running memtest86+ on both ram modules separately no errors were found, and I concluded it was not a problem related to the memory. I never resolved the issue. Within the last few months I have upgraded my computer, to the system described above, now an ABIT IP35 Pro and an Nvidia Geforce 8800GTS (and Windows Vista Home Premium, before I used XP Home Edition). I have continued to experience to experience graphics card crash issues with the new set up, now in the form of the infamous “nvlddmkm has stopped responding and has successfully recovered”. Today I thought I’d re-run memtest86+ (v1.70), and let one stick run for a few passes without error. The other however was problematic, on the first test I attempted it tested extremely quick (around 60 passes in one minute). Upon rebooting and running it again, it found 20000 errors on test #2 within one minute. I’ve tried both sticks in various DIMM slots on the motherboard, with voltage both at 1.9v and 2.1v, I get the same results each time. Does this suggest that there is a problem with one of my memory modules? I am not certain, since it is unclear whether the test is running properly. Any help or suggestions would be much appreciated.

RobAJ Posted October 14, 2007 Author Share Posted October 14, 2007 I would just like to stress that with the module which I think may be faulty, sometimes it passes many tests very fast, and sometimes generates a lot of errors. One of these two events seems to happen randomly on each test. The other stick always passes successfully. Link to comment Share on other sites More sharing options...

Corsair Employees RAM GUY Posted October 15, 2007 Corsair Employees Share Posted October 15, 2007 If one module is consistently passing, and the other one is failing with the same configuration, then let's get them or it replaced. Please follow the link in my signature “I think I have a bad part! Or “Tech Support Express” and we will be happy to replace them or it, please note that you are posting from the forum!

RobAJ Posted October 15, 2007 Author Share Posted October 15, 2007 Thanks for your response. Before I send it back, I'd just like to confirm your opinion on the result memtest86+ has produced. Rather than memtest86+ just reporting errors, sometimes the module which I believe to be faulty passes very quickly (at around 1 pass per second). Do you think that this test is running properly, can it be relied on? That said, the other module tests properly which is strange as I thought they were meant to be the same.

Corsair Employees RAM GUY Posted October 15, 2007 Corsair Employees Share Posted October 15, 2007 What do you mean by 1 Pass? Just use the default test in memtest and let it get through tests 1-8 and let me know the results. With a 1GB module it should take around 20 min to complete all 8 tests.

RobAJ Posted October 15, 2007 Author Share Posted October 15, 2007 That's the thing; the test which tests successfully does so as you describe. The one which I suspect to be faulty either passes very quickly at around 1 sec per pass (unlike the other module which takes around 20 mins) or fails very quickly giving 20,000 errors on test#2 in 1 minute (you can restart the test multiple times and one of these two events occurs; after doing this more times it seems it is more likely to pass very quickly). To me it doesn't look like the test is running properly. It is strange however, the fact that one module tests correctly while the other exhibits this behavior, when I believed they were meant be be *very* similar. I am testing both modules in the same DIMM slot on the same motherboard with the same settings; between each test I take one module out of the slot and but the other into the same slot.

RobAJ Posted October 15, 2007 Author Share Posted October 15, 2007 Just to clarify, I am using the default test in memtest86+. By pass I mean running without error through all 8 tests which takes around 20 minutes on one of my 1GB modules. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 15, 2007 Corsair Employees Share Posted October 15, 2007 Let's get them or it replaced! If its only taking a few seconds per pass on the bad module, there is something wrong! Link to comment Share on other sites More sharing options...
RobAJ Posted October 16, 2007 Author Share Posted October 16, 2007 Thank you for your help! I no longer have the original packaging, can I still RMA them without this? Do you have any requirements with regards to packaging? Rob Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 16, 2007 Corsair Employees Share Posted October 16, 2007 As long as the modules still have the original heatspreaders and labels we will replace them! Link to comment Share on other sites More sharing options...
RobAJ Posted October 16, 2007 Author Share Posted October 16, 2007 Great, I have submitted an RMA request through the technical support express website. Thanks for all your help, Rob Link to comment Share on other sites More sharing options...
