Hi FBS,
I remember researching these details and I'm sure somewhere it said it can take 2GHz on like some OC mode or something unless it was fake and unconfirmed info, but the official site says this.
Triple-Channel DDR3 1866/1800/1600/1333/1066 support
The motherboard supports DDR3 memory that features data transfer rates of 1866/1800/1600/1333/1066 MHz to meet the higher bandwidth requirements of the latest 3D graphics, multimedia, and Internet applications. The triple-channel DDR3 architecture enlarges the bandwidth of your system memory to boost system performance.
So now looks like that it can only go up to 1866 ?. Should I set it to that in BIOS?
