    Looking at 4GB (2x2) of DDR3 memory to run in Dual-Channel on an AM3 board (955BE CPU).

    The CPU memory controller supports 1333Mhz but the MoBo says that it allows 1666MHz as Overclock.

    1 - Does this mean that I can use 1600MHz RAM even the CPU controller only supports 1333?

    2 - Assuming I can, what would be best 1333 at CL6 or 1600 at CL8?

    3 - Assuming the 1333 at CL6 is better would I be better off just buying 1333 RAM or buying 1600 RAM (in the hope that when I slow it down I can reduce the CL).

    Cheers,

    Nigel

    You can use 1600 memory using a higher multiplier :)
