F3-12800CL8T-6GBRM running at 1066 on GA-X58A-UD3R Tags: Homebuilt Systems Last response: July 8, 2010 4:13 PM in Systems Share intrepid1701 July 7, 2010 4:58:20 PM I did my first system build using 6 x 2 MB Ripjaws F3-12800CL8T-6GBRM on a Gigabyte GA-X58A-UD3R motherboard and an Intel i7-960. For some reason, the memory is running at 1066 MHz. I'm wondering if anyone has a suggestion? My settings are factory default.

Memory speed is determined by multiplier and blck speeds, which you'd also have to set manually. Factory default's will not give you proper settings. Can't find your answer ? Ask !
