Hi all. I'm currently trying to find the source of my frequent BSOD I'm getting MEMORY MANAGEMENT, PAGE FAULT IN NON PAGED AREA & occasionally a SYSTEM SERVICE EXCEPTION. All my research tells me this is highly likely a RAM issue so I decided to test it. Downloaded Memtest 86+ v.4 which supports i5/i7 processors. 2 sticks of 2Gb Corsair XMS3 DDR3 1600 tested together in dual channel mode, I got no errors, tested for 4 hours, 7 passes, no errors. Hmmmm, I thought, strange, what if I try a stick at a time. I tried the first stick 1 in channel A1, no errors after 2 hours. Passed. Then I moved the same stick to channel A2, again no errors, passed. Confident that the first stick was healthy I then tried the second stick in A1 and straight away thousands of errors appeared. I thought I had found the source of my BSOD but out of curiosity I then tested the second (supposedly faulty) stick in A2 expecting an epic fail and to my dismay it passed NO ERRORS AFTER 5 HOURS. What is going on here? Faulty RAM or faulty RAM slots? Please help me somebody. I'm confused. Is it possible that a single stick of RAM just doesn't like a particular slot, despite the RAM working happily in another channel and despite it's twin brother matched pair works a treat in the slot that he didn't like??? I have flashed my BIOS to the 2nd newest one (there are said to be slight issues with the very latest BIOS for my board so most people are staying with the last one until the glitches have been ironed out). Should I open up an RMA with my supplier for the RAM anyway just in case it is starting to fail? Any help would be much appreciated. i5 760 2.8GHz Asus P7P55D-E PRO motherboard 4Gb Corsair XMS3 DDR3 1600 Win 7 64 bit Samsung Spinpoint F3 1Tb HD
if it passed memtest, it's unlikely to be a memory or board fault, more likely a driver issue try rubbing a clean piece of paper over the contacts of the memory that caused the faults. and make sure no dust managed to get in the contacts of the memory socket. when it worked fine in a2 after failing in a1 did you try putting it in a1 again?
Rich, thanks for that. I put the potentially dodgy ram stick back into A1 as you said and it is passing okay, no errors so far. I am stumped.
