I was looking at newegg and I saw "Integrated Memory Controller Speed: Dual Channel PC3-10667U (DDR3-1333) for 2 Module, Dual Channel PC3-8500U (DDR3-1066), Dual Channel PC2-8500U (DDR2-1066) What does this mean? Does this mean that this CPU can only handle 1333Mhz RAM? Also when I looked at the memory some mobos support it said "1600 O.C." can I still put regular 1600Mhz RAM in it?
Your first question: simply means the cpu works with the ram. Am2 cpus don't work with ddr3, but am3 runs with either ddr2 or ddr3, depending on the motherboard chipset. 1600 oc means the board has a lower speed limit for the ram unless you overclock the cpu. My h55 board only runs at 1333 for the ram, unless I adjust the cpu fsb from 133 default up to 160 (overclock). Then the ram will run at 1600.
