What is mobo OC?

[phthanh85]

I have a mobo with RAM frequency is 1066(OC)/800/667. What is "OC"? Should I use a 1066 CPU and a 1066 RAM with that mobo? Would that cause any damages to the mobo?

The OC means over clocked as it is not a stock speed/standard for DDR2 RAM. s for the CPU any that are supported by the mobo will be fine.
