    adding more ram to 12GB 6 slot setup

    TL2121 Community Member

      hey guys

       

      on my motherboard I have 6 ram slots (3 pairs- a blue slot and black slot in each pair) only 4 of the slots are filled-- from some preliminary research I see that it is better to have all slots filled-

       

      my question is right now there are 2-- 4GB sticks and 2-- 2GB sticks installed equalling 12 GB of ram- when I go out and buy should I buy 1-- 4 GB and 1--2GB and make sure all 3--4GB are in the blue slots and the 3--2GB in the black slots-does that matter at all or can the different slots/channels be populated with any combo of size as long as they are all filled up? (so I could just buy 2 extra 4GB sticks)

       

       

      just in case here are my system specs

       

      hp hpe 190t

      i7 980x

      12gb ram

      GTX260

      newly installed (by me!) 600 w corsair power supply (the 460 watt psu the system came with died after a year and a half- surprised it lasted that long))

      3 1TB drives (1 for programs, 1 for scratch disks, 1 for projects/exports)

       

       

      any help would be appreciated

       

      Thanks

      Tony

          In order of preference:

           

          • One Hex pack of 4 GB sticks
          • Two Tri-packs of 4 GB sticks
          • Two Tri-packs, one 4 GB and the other 2 GB sticks
          • ...
          • ...
          • ...
          • Mix some sticks

           

          Basically only option 1 is feasible, all the rest are compromises and can lead to mysterious hangs, BSOD's, freezes and data corruption.

            Mr Harm

             

            so let me summarize what you are saying- 6-- 4GB sticks is really the only way to go?

             

            If I decided to be cheap and had the 3 sticks of 4 and 3 sticks of 2 is the optimal setup in that config to put all the 4 in the blue slots and all the 2 in the black? (just curious)

             

            Thank you for your time and expertise

             

            ps-- looks like from what you wrote I'll be buying a 16GB kit of 4 sticks 4GB RAM

              Don't do that. I'm sorry if I was not clear, but you have two banks of three slots (blue and black) that are electrically distinct. Each bank need to be filled completely with the same sticks to optimize memory performance and preferably with identical sticks in both banks. Identical means a hex kit, tested and packaged to be used on a six slot mobo. If you buy a quad kit, you have one left-over stick. Seems like a waste of money to me. A tri-kit is cheaper. But two tri-kits do not guarantee you that they will work perfectly in the two banks. It may work, and it may not. Chances of two banks working happily together will increase if they are the same brand (G.Skill or Corsair), the same speed (DDR3-1600), the same type (Vengeance or Dominator) and the same production date from the same manufacturing plant.

                I was only saying to get 4--4gb sticks to add to the 2 I already have-- but you're telling me to go the hardcore route and buy the whole 24 gig pack at once--OK--question the ram that came with was 1066-- when I install the new 24GB 1600 speed-- would I have to go into bios to unlock the higher speed or will the cpu automatically detect the 1600 speed and the ram will run at that speed by default?

                  No, you need to go into the BIOS for that.
