I am using 2 kits of F3-12800CL9D-8GBXL on an ASROCK Z68 Extreme3 Gen3 motherboard. CPU is an Intel Core i-5 2500K at default speed of 3.3GHz. Wasn't aware that using two kits would cause issues when I made my purchase but now my lot is cast. I've had nothing but problems from the beginning (random crashes and now BSODs). Stumbled across this forum last night and learned that the memory was the issue. Originally I didn't pay attention to the matched pairs when I installed the memory (each pair have sequential serial numbers), but now they are matched in proper banks.
I now understand that I cant use XMP for timing.
I was able to get the system usable with the following settings:
Freq: 1333
tCL: 8
tRCD: 8
tRP: 8
tRAS: 24
CR: 2N
tWR: 10
tRFC: 107
tRRD: 4
tWTR: 5
tRTP: 5
Adjusted DRAM Voltage to 1.552 and VTT voltage to 1.075.
I am curious to find recommending settings that might allow me to get back up to 1600 with these 4 sticks.
Leaving the configuration set to Auto for XMP and just upping the voltage to the levels listed above didn't result in a stable system. But after using the settings above I can get through a memtest86 session running off a boot cd.
Would very much appreciate any assistance available.
Thanks!
