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. m 0 l Can't find your answer ? Ask !
