Pomsies Posted December 6, 2007 Share Posted December 6, 2007 I have a Asus P5B - VM motherboard that i recently bought, and i got for RAM Corsair CM2x1024-6400C4. I Put the computer together and it seems to run fine, everything works well and is recognized. The problem is when i play, say, Half-life 2 it will, every once and a while BSOD saying PAGE_FAULT_IN_NON_PAGED_AREA or something like that, and i cited Win32k.sys as the problem. People say that this is caused by bad ram or incompatible ram. I have run Memtest86+ a couple times over night, and it comes up with no errors.. then i ran the windows memory test. no errors. so im wondering if the ram just doesnt work with my board, or it may be something else. Thank you Link to comment Share on other sites More sharing options...

bigbuck08 Posted December 8, 2007 Share Posted December 8, 2007 If Memtest didnt come up with any errors I dont think the problem is with the RAM. But just to make sure, get the latest BIOS for your motherboard and update all of your drivers and also run windows update. Are you leaving your BIOS settings at default or do you have them set manually? Link to comment Share on other sites More sharing options...
Pomsies Posted December 8, 2007 Author Share Posted December 8, 2007 my bios is all up to date at "1001" and i updated everything i could, for drivers on my computer. i ran 2 different memtest versions first i ran the memtest+ then i ran memtest3.xx and it crashed in the middle of the test, on test 2 with 84 million or so errors, even when i disables lagacy USB service, so i dont know if one test doesnt work or not. My bios settings are not default, i changed my ram voltage to 1.95, and the clock to 800MHZ, but thats it. it errored the same way with it at default as well.

bigbuck08 Posted December 8, 2007 Share Posted December 8, 2007 Just to be on the safe side try running this again. Go to http://www.memtest.org and download the latest 1.70 version. Burn the ISO image to a CD. Set your BIOS defaults and boot from the CD. Allow it to run atleast two passes. It would probably be best to run each module seperately. This way you will know which stick is giving you errors, if any. It will probably take 30min or so per module. If it passed, there should be zero errors. If it has passed, set these manually in the BIOS: DDR2 Clock: 800MHz CAS Latency: 5T RAS to CAS Delay (tRCD): 5T Row Precharge (tRP): 5T Active to Precharge Delay (tRAS): 12T VDimm Voltage: 1.9v These are the tested settings for your RAM. Run Memtest again with these settings only if you passed at defaults. Link to comment Share on other sites More sharing options...
Pomsies Posted December 8, 2007 Author Share Posted December 8, 2007 ok, i ran the test and there were no errors after an all night 20 pass test. are you sure that its rated for 1.9v, because on the stick it says "2.1" and the timings on the case are 4-4-4-12 and 800mhz, I have two sticks of these XMS2 6400. im just wondering if that matters Link to comment Share on other sites More sharing options...
bigbuck08 Posted December 8, 2007 Share Posted December 8, 2007 Could you please tell me the Part Number and Version Number of your RAM? The following link will tell you how to read the Memory Label. Link to comment Share on other sites More sharing options...
Pomsies Posted December 8, 2007 Author Share Posted December 8, 2007 the part number is CM2X1024-6400C4 the version number is 2.1 (also right next to that it says 2.1v) it also says on the card 4-4-4-12, 800MHZ, 1024MB, XMS2-6400 thank you Link to comment Share on other sites More sharing options...
bigbuck08 Posted December 8, 2007 Share Posted December 8, 2007 Hmmm. I believe this is your RAM here: TWIN2X1024A-6400 The first thing written under features says "Two matched CM2X512A-6400 modules". Then if you look under Tech Specs it says they were tested at 5-5-5-12 @ 1.9v. To be absolutely sure you will have to wait for RAM GUY to respond on Monday.

Pomsies Posted December 9, 2007 Author Share Posted December 9, 2007 ya, we should because, honestly, i cant even find the product i bought on the site.... because its a pack of 2 1024MB sticks, giving me 2GB of ram. Link to comment Share on other sites More sharing options...
bigbuck08 Posted December 9, 2007 Share Posted December 9, 2007 Where did you buy these from? The RAM with the exact part number you gave is sold in 1GB sticks by themselves, atleast thats all I could find. If they came in a kit together the part number should be TWIN2X2048-6400.

Wired Posted December 9, 2007 Share Posted December 9, 2007 CM2X1024-6400C4 is the correct part name for a 1 GB stick of PC6400 Cas4 memory. A Twin2X pack made of 2 of these sticks tested together would be called Twin2X2048-6400C4. Link to comment Share on other sites More sharing options...
Pomsies Posted December 9, 2007 Author Share Posted December 9, 2007 if that is true, then the ram needs to run at 2.1volts, meaning i need different ram for my motherboard.:[pouts: Link to comment Share on other sites More sharing options...
bigbuck08 Posted December 9, 2007 Share Posted December 9, 2007 Yes you are correct. After looking at your motherboards manual the Vdimm will only go up to 1.95v. You can try setting the Vdimm to that and then test the RAM with Memtest to see if it will be stable otherwise youll need a new motherboard.

Pomsies Posted December 11, 2007 Author Share Posted December 11, 2007 bump, will you comment on this Mr. Ram Guy. I just want to know what you think about my ram Passing memtest 20 times, even with ram that is incompatable, but it will crash while doing some pretty tough programs. what would you suggest sir?

Corsair Employees RAM GUY Posted December 12, 2007 Corsair Employees Share Posted December 12, 2007 Sounds like its not getting enough power, what did you set the timings to? I would try Cas 5-5-5-15. Link to comment Share on other sites More sharing options...
