TheAbbot Posted December 1, 2011 Share Posted December 1, 2011 According to the Corsair compatibility list my MSI P35 Neo2 should work fine with my TWIN2X4096-6400C5. However, I've been having problems which I think I've narrowed down to the memory (which is a replacement I bought a few months ago). The issues are: BSODs in Windows (maybe once or twice a day) of varying naturesOccasional non booting (usually after a BSOD) unless left off for a whileMemtest86+ hasn't reported any faults, but the actual computer can hang during running Because the faults are random, it's time consuming pinpointing the problem and I know I need to run one stick at a time to see if just one of them is causing the issue (I'm currently trying different memory to double check my memory diagnosis). But I'm wondering if anyone can suggest whether the memory is likely to be faulty or whether I should try relaxing the timings a bit (I'm using the SPD timings at the moment), even though the SPD 5-5-5-18 should be okay? If so, what should I change? I should point out that I updated my BIOS - there was apparently a known issue with 4GB memory, but it was addressed in the version I now have.

Corsair Employee RAM GUY Posted December 1, 2011 Corsair Employee Share Posted December 1, 2011 I would load setup defaults and set the memory Voltage to 1.9-2.0 Volts and test them with http://www.memtest.org. If its still not stable then test them one at a time. Link to comment Share on other sites More sharing options...
TheAbbot Posted December 1, 2011 Author Share Posted December 1, 2011 Thanks for your response, Ram Guy. By "setup defaults", you mean reset the CMOS settings to factory defaults, I assume? I'll do that and try increasing the voltage as you suggest. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted December 2, 2011 Corsair Employee Share Posted December 2, 2011 Yes go to BIOS setup and Load setup/optimal defaults then set the settings for Voltage and what not. Link to comment Share on other sites More sharing options...
TheAbbot Posted December 12, 2011 Author Share Posted December 12, 2011 Just wanted to say "Thanks!", Ram Guy. I've been running my machine for about a week now with the memory at 1.9V instead of the rated 1.8V and so far, it seems to have fixed the problem. I have mixed feelings about having to do this for memory supposedly rated at 1.8V (and my previous 2GB Corsair memory ran fine on this MB at the lower voltage), mainly from a heating point of view (back of an envelope calcs suggest an 11% rise in power use). However, it seems like the best solution. I may try dropping it to 1.85V and see how it goes on that. For reference (for anyone with similar problems on an MSI Neo2 motherboard), the memory voltage selector in the BIOS is greyed and the help text / manual suggest this is a read-only value. It's not: you can change it with the "+" and "-" keys on the keypad. Link to comment Share on other sites More sharing options...
TheAbbot Posted January 24, 2012 Author Share Posted January 24, 2012 Okay... this hasn't worked. I've done some more experimentation and determined that it is a fault and it lies within one of the two modules. I've requested an RMA from the place I bought it, but: They want to charge me postage both ways as it's more than 14 days since I bought itThey are threatening me with an additional £10 charge if they can't find a fault. As the computer sometimes runs for a week or more between incidents, I'm not confident they'll find the problem As the product was faulty when I bought it, I don't really think this is fair. If I return the memory back to Corsair directly, what are their policies on postage costs? I'm in the UK, so information relevant to the UK market (if any different from elsewhere) is most appropriate for me. I've looked, but can't find any info on this on their website.

Wired Posted January 24, 2012 Share Posted January 24, 2012 You pay for shipping to Corsair, they pay for shipping back, no extra charges or anything. Note that their EU RMA Depot is in NL. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted January 27, 2012 Corsair Employee Share Posted January 27, 2012 This chipset was lets say picky with 1333FSB CPU's and if the memory Voltage seemed to help I would add a bit more to it and set it to 2.0 Volts, and or set the NB Voltage +.1 Volts as well.
