    Hey guys, I just looked at CPU-Z through wPrime, and it says that my RAM is only clocked in at 327.9 mhz. Is this because I'm running dual-channel?

    Heres A Screenshot

    Thanks,

    DDR = double data rate. CPU-Z is only showing the actual clock speed, not the effective clock speed.

    It can more correctly be described as 333MHz speed, 667MT/s (megatransfers per second).

    Yeah, with DDR ram you take the actual clock speed and double it, so its your 327mhz x 2 = around 667.

    So I guess this is normal? I've never heard of it before.

    Yep thats how DDR works... It transfers data on both the rising and falling edges of the clock without increasing the bus frequency....
