I've just finished building my new computer and I'm running into issues with my memory. In the BIOS I've got the frequency set on 1866mhz, which it even auto detects. However, whenever I'm running Gigabyte EasyTune (which I've since removed) or running a 3d Mark test, it says my ram is only running at 800mhz. I'm out of ideas since everything looks fine in the BIOS. My only thought is that there's a compatibility issue, but I wouldn't think it would even work if that was the case.
Here's my setup:
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) F3-14900CL9D-8GBXL
MSI R6950 Twin Frozr III PE/OC Radeon HD 6950 2GB
Intel Core i5-2500K Sandy Bridge 3.3GHz
