Klutyz Posted June 21, 2009 Share Posted June 21, 2009 So I initially installed Windows 7 (7100) on my EVGA Classified (759) with one stick of Corsair Dominator GT 1866 2GB. Everything installed fine, got it up and running, installed the two other sticks and Windows recognized them immediately. Timings were set fairly relaxed 9-9-9-24 1T. Over the next couple of months I would get an occasional BSOD. These errors ranged from PFN_LIST_CORRUPT, various page file errors and towards the end just all kinds of failures without any specific error message except for long numbers and letters. I did as much research as possible with the errors I did understand and it seemed to point to memory failure. At first, I figured I'd try just a clean reinstall with Windows and go from there. When I tried this though, it would get about 6% through the "Expanding Windows Files" part and then tell me the installation could not continue because the files were corrupt? How could the files be corrupt straight from the Windows 7 disc? I'm not sure if this is correct or not, but I assume that these files were being transferred to RAM and were getting corrupted somehow. I finally resorted to taking everything down to just vid card, one stick o'ram, hard drive, loaded defaults into BIOS, and cleared CMOS. Windows installed just fine this time. Now I wish I would have tried booting with just one stick instead of reinstalling windows completely....but live and learn. So here is my question: Since I feel I've narrowed it down to one of my sticks of RAM being faulty, what is the best way to test each individual stick? I'm not sure if they are all bad since Windows installed just fine on the stick I have currently plugged in. Any advice? Link to comment Share on other sites More sharing options...
Wired Posted June 21, 2009 Share Posted June 21, 2009 Test one stick at a time in each slot using Memtest86+. What voltage is your memory currently set to? Link to comment Share on other sites More sharing options...
Klutyz Posted June 22, 2009 Author Share Posted June 22, 2009 Test one stick at a time in each slot using Memtest86+. voltage is your memory currently set to? I tested each stick with memtest and two sticks passed 3+ passes without any errors. The third stick starting getting errors almost immediately. Is it necessary for me to send all 3 back? The voltage is on auto and shows as 1.56 in EVGA Eleet. I think that is a little less than what it says in the bios though. I'll have to check again. The specified voltage is 1.65 though. Should I just go ahead and manually set it to that? Link to comment Share on other sites More sharing options...
Wired Posted June 22, 2009 Share Posted June 22, 2009 Yes, set it manually and retest. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted June 22, 2009 Corsair Employees Share Posted June 22, 2009 You will need to set the QPI Voltage to 1.6 Volts as well. Link to comment Share on other sites More sharing options...
Klutyz Posted June 22, 2009 Author Share Posted June 22, 2009 You will need to set the QPI Voltage to 1.6 Volts as well. Do you mean the QPI VLL Vcore? That's the only place I see anything with "QPI". Its currently set to 1.1v. Or are you referring to the CPU Vcore? Link to comment Share on other sites More sharing options...
Klutyz Posted June 23, 2009 Author Share Posted June 23, 2009 I set the memory profile to XMP and manually set the timings to 7-8-7-20. DRAM/DIMM Voltage was set to 1.65 and QPI/CPU VTT was at 1.62. Ran Memtest86+ 2.11 for 4 passes and the same two sticks passed flawlessly once again. While the 3rd stick failed almost immediately. I've already filled out an RMA request. Haven't had one BSOD since taking out the "culprit". Link to comment Share on other sites More sharing options...
