SK10H Posted January 9, 2011 Share Posted January 9, 2011 Hi, I am using CMZ4GX3M1A1600C9 x 2 on the blue slots A2 and B2 on Asus P8P67 using beta BIOS 1053 build on Jan04,2011. I am having trouble running the memory at DDR3-1600, not the memory fault. http://img228.imageshack.us/img228/4981/memspeed.jpg As the screenshot shows, memory speed is at 667. I tried to adjust the AI Overclock Tuner to Auto/Manual/XMP, tried them all while setting the Memory Frequency to DDR3-1600, but cpu-z report 667 only. I confirm it using AIDA64 benchmark comparing other 1600 results. I am able to adjust the command rate to 1T within the Dram timing section, but apparently not the speed. I am stuck at DDR3-1333 while processor is flying at 4.8GHz. :p: I am stuck... :sigh!: When I choose DDR3-1866 with VDimm at 1.65v and loosen the timings, it won't post at all. I think there might be some incompatibility here that need to be resolved with newer motherboard BIOS. Link to comment Share on other sites More sharing options...
