    Mixing RAM modules

    Asrock Z87M extreme4 mobo with i7 4790k cpu

    I have four slots, two are filled with 8Gb DDR3 800Mhz modules, two are empty.

    Can I put two 4Gb PC3-12800 in the other two slots please?

    If I can is it important what slots which goes in?

    I think quantity is more important than speed for my image processing.

    Will I have a problem if I simply try it?

    Thank you.

      You should check the manufacturer of the computer (if off the shelf) or the motherboard (if you built it) before attempting. Some motherboards allow you to mix and match memory modules and others require identical memory modules. Personally, I would not mix RAM but I would choose identical modules (even if from different manufacturers) with the same specifications.

      What you have are 2 sets of ram that are the same speed.

      The best way to set that up is to put the matched pairs in the proper slots to get dual channel.

      Even if set up proper that does not mean the mobo will accept the new ram.

      Before you install the new ram run this and post a link.
