Should I use one 8 GB stick of RAM or 2x4GB?

I meant to buy a 2x4GB kit of RAM but accidentally bought a single 8GB stick of RAM. Should I send it back and get the 2x4GB kit or just go ahead and use the 8GB stick.

HyperX Fury 8GB 1866

If it matters I'm using an AMD FX-8350 CPU and Gigabyte GA-990FXA-UD3 motherboard with a MSI R9 280 GPU.

  1. Use 2x4 so it runs in Dual channel mode for better performance. :D
  2. Yeah AMD needs all the memory performance you can spare.

    Realistically the worst case scenario is probably 20% difference with almost NO difference in most games.

    I don't know what the above comment about AMD means though perhaps he's referring to APU's which have a GPU that shares the System RAM and thus that memory needs to be fast. Not what's going on here.

    So, overall the difference is probably minor. Personally, I'd probably go with 2x4GB.
  4. Stick with 2 x 4GB configuration as it gives you better performance plus it will reduce the stress on Memory Host Controller.

    When we use two sticks, it creates Dual Channel which operates at 128 bits interface likewise with quad channel which operates at 256 bits.

    Hence you'll gain performance gain.
