Ive been wondering why mines been running at pc3 8500. How do i change this to 12800, and i guess by this i mean how do i change the timings. Will there be a perf increase if i change the timings to 8-8-8-24? For full system specs check my member config, and now some pictures:
Just to add to what's currently visible, you're currently running at 1333 according to your post. The clock is doubled from the readings in Cpu-z, where it says pc2 8500 is just the default startup settings for compatibility. On the previous page (memory) that displays the current settings of 666.7, double that you have 1333. To achieve the higher setting of 1600 voltage must be set to 1.65 which is the manufacturers specification. The 1.5 v setting currently used is standard voltage for ddr3 chips. In your bios prior to the ddrii timings sheet you should see a ram setting for EPP which refers to enhanced performance profile on gigabyte boards. Enable Epp mode for clock speed, right beneath that should be Epp voltage enable this also. You must enable the EPP voltage setting or you probobly won't be able to post on next boot after setting. Run Cpu-z again and click memory, you should see 800mhz, which doubled is 1600. You may need to type in ctrl F1 to reach enhanced bios screen settings once you come up into the initial bios screen. Good luck
to rand_79: I did tweak to get to 8-8-8-24 on all chips, but im not sure if its 100% stable, i will have to memtest it. Also will these timings at 1600Mhz give any performance increase over what i had before?
