davidh11 Posted September 21, 2009 Share Posted September 21, 2009 Can anyone suggest what might be going on? PC runs for several days, then reboots. Memtest86+ shows a lot of errors. Errors remain after restart either by Reset button or Power button (configured for 'off') System boots OK into Memtest86+. Many errors shown. However if I disconnect the main lead for 5 seconds, the problems are cleared. Memtest86+ will not detect errors even after many hours. Errors return after several days running Windows (2000) PS is only 370W but as you can see below this system has modest power needs. System is well cooled - Processor 45, System 34, GPU 53 Any suggestions?? DavidH Bios set 5 5 5 15 2.1v Spread Spectrum - Disabled Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 22, 2009 Corsair Employees Share Posted September 22, 2009 That symptom would suggest a thermal or voltage issue with the MB, but I would suggest testing the memory in another system to be sure. Link to comment Share on other sites More sharing options...
Mr. G Posted September 28, 2009 Share Posted September 28, 2009 My system will become unstable after its been running for a few days to 2 weeks.... If I reboot and run memtest86 at that point, I get thousands of errors/pass. If I shut down the computer for 5-10 seconds, and then run memtest again..... I get no errors, even if I let memtest run for 24 hrs (20+ passes). I need to find a solution to this problem! I have a 625W PS, so I don't think my power supply is an issue..... edit: I have 4 sticks of memory, and I've been using only 2 of them at a time..... Despite rotating them, the problem seems to keep occurring. I've also tried default BIOS settings, manually setting the timings, using slower memory speeds, and using different memory slots without success. I don't think its the memory at this point, but I'm not sure what else it could be. Any advice on how to further diagnose this problem would be greatly appreciated!!!!

Corsair Employees RAM GUY Posted September 29, 2009 Corsair Employees Share Posted September 29, 2009 I would try RMAing the MB or CPU from what you have posted. Link to comment Share on other sites More sharing options...
indica Posted October 10, 2009 Share Posted October 10, 2009 http://forum.corsair.com/forums/showthread.php?t=81868 all 4 of us are using diffrent motherboards is it likley that we all just have bad luck? :mad: Link to comment Share on other sites More sharing options...
Mac99 Posted October 11, 2009 Share Posted October 11, 2009 As Indica mentioned by linking to my thread, I have the exact same problem. And this problem sounds very similar too: http://forum.corsair.com/v3/showthread.php?t=81837 The "Clock Skew" tweaking I mentioned increased the time before the system fails from ~8 hours to ~19 hours but that's it so far. Like Mr. G I also have 8 GB of RAM. And running with only 4GB didn't help me either. We all have different Mainboards, CPUs and Power Supplies. The only thing we all have in common is the same RAM so I think it's a good guess to believe that's the cause of the problems. Maybe there's a bad batch? What revision of the RAMs do you all have? Mine are are all Rev 2.1. One more thought: The 1x revisions needed 2.2 Volts which has been reduced to 2.1 Volts for the later revisions. Could that be the problem? Is it possible that this was a little too optimistic? That the later revs still need higher Voltage to work stable? Anyway, I'm glad that I'm no longer the only one with this problem. Maybe more input finally helps solving this issue. Link to comment Share on other sites More sharing options...
indica Posted October 11, 2009 Share Posted October 11, 2009 Mine are all version 2.1 also, says right on the stick 2.1 volts I also am tryin to run 8gb running with 4 dosent help. Although one of my sticks now has permanent errors that arent wiped when i power off, im in the process of RMA at the moment when i get my 2 fresh sticks i will try just those, maybe i will get lucky and its just all bad luck with faulty ram.

indica Posted October 13, 2009 Share Posted October 13, 2009 ok so before i RMA my MB and CPU i replaced the ram with some 15 dollar crap from wal mart and what do you know ive been stable ever since Link to comment Share on other sites More sharing options...
Wired Posted October 13, 2009 Share Posted October 13, 2009 What's the size / speed of the memory? Link to comment Share on other sites More sharing options...
indica Posted October 13, 2009 Share Posted October 13, 2009 the new ram? 2 one gig sticks of ddr2 667, so smaller and slower, any ideas? Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted October 15, 2009 Corsair Employees Share Posted October 15, 2009 With 4 modules I would suggest setting the memory frequency at DDR667 and set the memory Voltage to 2.1 Volts and set the NB/MCH/SPP Voltage to +.2 Volts as well and test the system with http://www.memtest.org. In addition, with some MB's (Mostly ASUS) you have to disable legacy USB in the bios when running any memory test. Link to comment Share on other sites More sharing options...
davidh11 Posted November 20, 2009 Author Share Posted November 20, 2009 This is an update to the problem I raised at the head of this thread: I have TWO identical PCs, both have MSI P43 Neo F and TwinX 4GB TWIN2X4096-8500C5DF I have been testing both PCs with a single memory strip in slot 1, rotating the four strips through both PCs. Test have been: Spread spectrum always disabled Latest BIOS (V1.10) on both boards 5-5-5-15 1066 2.1v 5-5-5-18 1066 2.1v 5-5-5-18 800 2.1v 5-7-7-24 1066 2.1v 5-7-7-24 800 1.8v 5-7-7-24 800 2.1v I have obtained alternative memory (DDR2 800) running at the auto setting of 6-6-6-18 800 1.8v This is stable in both systems both singly and as a pair. Falure returns with Corsair strips. Now there seems to be a pattern about the failures: - two strips BSOD in hours, the other two take several days - after failure memtest86+ often (always??) reports the same byte in error for same strip, but different for byte for each strip (1-000000f0, 2-0000ff00, 3-00f00000, 4-00ff0000) (failures may be 1 to 4 bits within each 'f') Where do I go from here?
