Kingston 2x2GB + Corsair 2x2GB?

I have two Kingston DDR3 memory modules installed (link here), so can I use these Corsair memory modules (here) for expanding my system memory?

Are there any issues with compatibility or efficiency with using two different manufacturers' memory combs?

  1. Most of the time different ones work together, the most important thing is that they are similar in voltage requirement. It is though recommended to use matching modules.
  2. Technically, only 1 voltage can be set for memory, but you can configure timings separately for each channel. The Corsair specs are DDR3 Timing: 8-8-8-24 1.65v. Is the Kingston also 1.65v?

    Why take a chance, just to save $20? I would get the same memory just to be safe.
  3. Clearly, there certainly can be compatibility issues in any mixing. In general, I suggest using the same 'series' with identical Frequency, CAS Timings, Voltage and Type {incl same Mfg}. This is especially important if you have an OEM MOBO like Dell, Gateway, HP, etc where you cannot modify attributes like DRAM Voltage, CAS Timings, etc.

    If either the 'SPD' or Rated attributes perfectly match then yes you can mix-match, but it should be done with caution. Though mixing wouldn't be my choice, and I would prefer one less potential problem even if it meant some additional cost with no aggravation.
