Adding dual channel to dual channel?

Hey guys
i want to add another dual channel memory kit to my existence Corsair Vengeance 1600mhz 2x4gb ddr3 dual channel kit 9 9 9 27 1.5v

iam wndering whats the type of memory that will run ok with the ones i already have
i want to buy a
2x8gb kit
so now i have a couple of questions

Is it ok to install a kit with 1.65v? Or with faster speeds? Or diffrent timings? Or diffrent cas?
And if its ok do i have to change something when its istalled?

  1. Do you need more ram ? make sure that you need it...
    I don't recommend going with a kit with 1.65v, the maximum voltage for ivybridge is 1.5v, so if you want to add ram, get it with no more than 1.5v, and yes, you can do it with 2x8GB or 2x4GB as long as it's in the same channel(color dimm slots).
    You don't need faster speeds or different timings, it will not increase the performance.

    ok thanks but i meant if its ok to add the 2x8 kit with timing that is diffrent than the one i have
  3. Yes.

    Yes.

    so the ram with 9-9-9-27 timing will run at its own speed and it wont get its speed changed if the other kit timing is diffrent?
    btw may that cause problems if i had a kit thats speed is diffrent than the other kit?
  5. Yes, it will run at dual channel, it will run at the slower timing speeds.
