Finished building a new rig with the aforementioned mobo and ram. upon bootup, BIOS shows the RAM(2 2Gb sticks) operating at 573 Hz. it's in dual channel mode so I suppose it's really running at 1146. However, the mobo supports 1333 with OC to 1600 and 1800, so the ram should be running at at least 1333/2 in BIOS. When in BIOS, the memory speed, etc is grayed out, I can't change it. I can go into the OC tab and OC it, but based on multipliers of the 573. How do I get the BIOs to recognize it to 1333, and then how do I OC it to 1600/1800?
