1 out of 4 of my Corsair XMS3 DDR3 1600 4GB RAM sticks failed. I ordered 1 stick to replace the bad one. Do I need to order 2 at a time and replace one of the good ones as well, or is just 1 ok?

I have an Intel(R) Core(TM) I7-2600K @ 3.40 GHZ computer with 16GB of ram (normally).

  1. It's always best to replace dual channel memory in matched pairs. But if you got the same make, voltage, timings, speed, etc as the other one, it will probably be OK.
  2. Did it fail under Memtest by itself, with mixed sets (packages of DRAM, it may be fine, if so can try voltage iming adjustments to get them all to play together
  3. CMX16GX3M4A1600C9 is a kit of 4 x 4GB.

    If one fails, Corsair will replace the whole kit. You should run Memtest for Corsair and get a RMA number from them.

    Good point. I wasn't aware of that being in the warranty. I guess 'cause I've never had to make use of it.
    I've got 2 pairs of Ballistix by Crucial. I wonder if they have the same policy.
