Phil2010 Posted October 13, 2010 Share Posted October 13, 2010 I have the Gigabyte GA-X58A-UD3R and Corsair XMS3 6GB (3x2GB) DDR3 12800C9 (1600MHz) When I set it to 1600 with the right timings and near enough right volts 1.648v, crysis crashes but if the mem is running at 1333, crysis runs fine? Ive tried setting the ram volt manually at 1.65, but there isn't a 1.65, it just jumps from 1.640 to 1.660, also tried upping the mem volt to 1.70, but crysis still crashes.

trackrat Posted October 13, 2010 Share Posted October 13, 2010 The RAM has been tested and confirmed to function properly at 1600 MHz. 9-9-9-24 2T @ 1.65V but your CPU is only guaranteed to run the RAM stable at 1066/1333 MHz. XMP profiles don't seem to be 100% supported by Intel/AMD even though they suggest that your CPU will run with these memory specifications. Your RAM voltage can be 1.64V or 1.66V without problems. 1.65V is the nominal voltage for the speed rating of the RAM. You may need to change a variety of BIOS settings in an effort to make your PC run the RAM overclocked at 1600 MHz. - or it may never run stable overclocked if your hardware is unwilling to do so. See my signature for details. http://www.techreaction.net/2010/09/07/3-step-overclocking-guide-bloomfield-and-gulftown/ Link to comment Share on other sites More sharing options...

Also, can you add your system specifications to your dropdown menu as requested at registration please. ::pirate:: Link to comment Share on other sites More sharing options...
Phil2010 Posted October 13, 2010 Author Share Posted October 13, 2010 Well its not my system, Im building it for someone.. Here are some screenies, as you can see its set to 666mhz, but the motherboard sets the memory a tad faster then 666. http://img87.imageshack.us/img87/3853/26624067.jpg Link to comment Share on other sites More sharing options...
trackrat Posted October 13, 2010 Share Posted October 13, 2010 The i7-930 is only guaranteed by Intel to run memory at 800/1066 MHz. If it runs 1333 MHz. stable you should be very happy. http://ark.intel.com/Product.aspx?id=41447 Link to comment Share on other sites More sharing options...
Wired Posted October 13, 2010 Share Posted October 13, 2010 Have you tried resetting the BIOS and enabling XMP? Should work just fine. Link to comment Share on other sites More sharing options...

trackrat Posted October 13, 2010 Share Posted October 13, 2010 One could argue that the higher frequency places more thermal load on the CPU but if it runs stable I doubt it will cause you any issues. Many people have been running OC'd CPUs/memory/Vid cards for decades without issues. Link to comment Share on other sites More sharing options...
