1 out of 4 of my Corsair XMS3 DDR3 1600 4GB RAM failed. I ordered 1 stick. Do I need to order 2 at a time, or is just 1 ok?

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). I bought the computer via cyberpowerpc a while back.

  1. I always thought you send back the memory in pairs. Meaning that if 1 stick of a pair failed, you RMA the entire pair. Although it never made sense to me to do it like this. I remember G. Skill telling ppl to do it this way a few years ago, but this is Corsair memory.

    I am not 100% certain on that. Maybe someone else could chime in on this one? Or better yet, contact Corsair about it. Their customer support is second to none, I do know that from experience.

    I took out the one that isn't working and it's running fine on 3 sticks now, but someone on a game forum that I'm on said I need to install 2 at a time. I ordered one, but now I'm wondering if I need to order 2 new ones or what.

    He's probably referring to running dual channel mode witch requires 2 sticks. Otherwise some of your memory would run in single channel mode since it's missing a stick out of its pair.

    Dual Channel modes offers more performance out of your memory.
  4. A single stick replacement will work just fine, as long as the speed/voltage/timings are the same.
