I recently built a new system using the following:
Gigabyte GA-MA790GPT-UD3H mainboard (BIOS v. F3, which is the latest non-beta version)
AMD Phenom II X3 720BE CPU
4 GB (2x2GB) G.Skill F3-12800CL9D-4GBNQ DDR3 RAM
Enermax Infiniti 720W PSU
I set the RAM to run at 1600 in the BIOS by following the settings posted in this forum posting (tCL 9 - tRCD 9 - tRP 9 - tRAS 24 - CMD 2. Memory voltage should be set to 1.7V). The PC seemed to run fine, but after a little while I noticed intermittent crashes, sometimes from resume from Sleep and sometimes when running a game. After some troubleshooting, I ran Memtest86+ and it gave me a test result of several thousand errors after only 7-8 minutes.
I then tried adjusting the timings and voltages slightly a few times. This did not solve the issue as Memtest86+ still reported many errors when testing the RAM. However, when I returned the BIOS to run at AUTO settings (i.e. 1333MHZ) Memtest86+ found zero errors. after about 2 hours of testing.
From this testing, it appears that my RAM modules are not capable of being stable at 1600 for some reason.
Could someone please help me find a solution to this problem? I bought this RAM because it was registered as compatible/tested with my motherboard, and I'd like to run it at 1600MHz.
thanks,
Anthony
