DaGooN Posted January 25, 2010 Share Posted January 25, 2010 hi, got a lil problem here with my memory i think ok the thing is, if i choose XMP, my ram reads as 1600 - 1600 but will crash after a while. even with 1.66v QPI/VTT 1.3 Vcore 1.2 8-8-8-24 but if i set it on Manual SPD and choose x12. it reads as only 1066 - 1600? and works with 9-9-9-24-1 my memory is this.. - New XMS3 Heat Spreader - Matched Triple Kit - 1600MHz - 8-8-8-24 - 1.65V - Lifetime Warrant http://www.overclockers.co.uk/showproduct.php?prodid=MY-180-CS&groupid=701&catid=8&subcat=1389 ive Ran Memtest86 4.0 and 5 passes = no errors ran Prime95 8hrs = no errors. if i use XMP i dont last in prime95 more then 1hr.

Corsair Employees RAM GUY Posted January 25, 2010 Corsair Employees Share Posted January 25, 2010 Please go ahead and update to the latest bios and than load optimized defaults in bios. Then go ahead and set the timings to 8-8-8-24 (CAS-tRCD-tRP-tRAS) and the memory voltage to 1.65v. Then go ahead and set the memory frequency to 1600MHz make sure not to change any of the bclock settings. Let us know the results. Link to comment Share on other sites More sharing options...
DaGooN Posted January 25, 2010 Author Share Posted January 25, 2010 first things first, im running the latest bios F9M for Gigabyte GA EX58-UD5. all drivers are up to date along with windows updates. i was told this about the motherboard. "one number will show the default speed 1066 thats what the bios sets it at,and next to it will be the current speed that youve set it too 1600mhz" ive also done test on stock with 1.64 and 1.66 (as i dont have 1.65v setting) and it looks like this. Performance Enhance [standard] Extreme Memory Profile (X.M.P.) [Disabled] System Memory Multiplier (SPD) [x12] 1066 - 1600 DRAM Timing Selectable (SPD) [Manual] then i add. 8-8-8-24-Auto (not sure if its 1 or 2T, but ive done both and it still crashes) with 1.5v & 1.64 & 1.66 still will crash within 20mins, in windows 7 64bit. :Note it works fine like this. Performance Enhance [standard] Extreme Memory Profile (X.M.P.) [Disabled] System Memory Multiplier (SPD) [x10] 1066 - 1333 9-9-9-24-1 1.66v and passes 8hr of prime95 & 5 passes with Memtest86 4.0 = no errors no crashes.

Corsair Employees RAM GUY Posted January 25, 2010 Corsair Employees Share Posted January 25, 2010 Try testing each module one at a time in the slot furthest away from the CPU with memtest from memtest.org at 1600MHz to see if one particular module is causing the lockup. If all of them show no errors after several passes try each slot individually to see if one slot may be causing the problem. Please let us know the results Link to comment Share on other sites More sharing options...
DaGooN Posted January 25, 2010 Author Share Posted January 25, 2010 thats a hell of alot of testing lol.. but will do. :roll: Link to comment Share on other sites More sharing options...
MJinZ Posted January 25, 2010 Share Posted January 25, 2010 Before you do that, try setting XMP and increase your VTT to 1.35V. I know my Dominator's XMP profile sets it to +150 (1.2 + 0.15 = 1.35V), even though I run mine at 1.25 VTT just fine @ 1600 speeds. Your CPU's memory controller may need more juice for some reason though. Link to comment Share on other sites More sharing options...
DaGooN Posted January 25, 2010 Author Share Posted January 25, 2010 my QPI/VTT is already @ 1.35v and yet it still fails in windows. i just want to rule out the memory, mobo , CPU ect. i think it might be windows 7 64bit or PSU? since what i get is the same as these folks who's win7 64bit Freezes.. Random. http://www.sevenforums.com/browsers-mail/2909-7-freezes-while-browsing-internet.html there is no BSOD! No Error msg. just Computer will Restart.. there is something in event Viewer though.
