Does it matter which channel RAM is placed in?

I'm currently building a computer for a friend, and I'm finding that the CoolerMaster Hyper 212 heatsink and fan is being obstructed by the ram somewhat on the Gigabyte board. I was wondering if it matters what channel is used for a dual-channel DDR3 set up. as in, instead of using 1st slot and 3rd for the two sticks, could I use the 2nd and 4th?

Thanks in advance!

  1. Yes, you could move them, and yes you'd still have the dual channel operation.
  2. Thank you T_T. :)
  3. Read the manual. I think you will find it certainly does matters....if you had given us the model, wuda looked it up for you.

    For example, the p55a-ud3p manual shows two possibilities (pg 16):

    2 modules, one in DDR3_1 and DDR3_3
    4 modules in all 4 slots


    DDR3_2 is the 1st one you come to going left to right from the CPU
    DDR3_1 is the 2nd one you come to going left to right from the CPU
    DDR3_4 is the 3rd one you come to going left to right from the CPU
    DDR3_3 is the 4th one you come to going left to right from the CPU
