RAM 1x4GB, 2x2GB?

I'm planning on getting G.SKILL 1x4GB DDR3 1333, as my motherboard supports up to 16GB, and that would be the cheapest option in the long run, rather than buying 2x2GB, and replacing it later. I'm not sure, however, about running single channel. I've heard the difference between single and dual channel in negligible, but I wanted to know if there are any possible issues. Should I stick with 1 stick of 4GB RAM, or 2 of 2GB?

Also, what generally is the best brand for RAM?

  1. Welcome to Tom's Forums! :)

    It would be very helpful if you post the exact MOBO in question, and what exact RAM you have currently. I prefer links!

    In general and for most 4-DIMM MOBOs you need to purchase Matched-Sets -> Matching exactly what is already installed, and NOT to mix-match Speed, CAS timings, Voltages, Types {incl brands/IC/chips per side/etc}.

    If you have NO RAM then Dual Channel is the most efficient over Quad Channel; therefore if the Goal is 4GB then get 2X2GB.

    I prefer Corsair and I strongly encourage you to input your MOBO info into the Configuration tools {see @ bottom} -> http://www.corsair.com/
  2. To clarify, I don't actually own a computer yet, this is for a new (my first, actually, so i'm a bit of a noob when it comes to computer parts) build.

    My motherboard's an ASRock 870 EXTREME3 (http://www.newegg.com/Product/Product.aspx?Item=N82E16813157198&cm_re=asrock-_-13-157-198-_-Product)

    Here's the RAM I was looking at
    G.SKILL Ripjaws Series 4GB 240-Pin DDR3 SDRAM DDR3 1333

    And yeah, I realize the sticks must match. I was planning on buying one now, and another of the same at some point in the future.
  3. The ASRock 870 Extreme3 is a Dual/Quad DDR3 MOBO, and I would suggest that you install RAM is sets of 2. I would not recommend one now and one later; the 'Kits' are hand matched sets and it's not the 'way' you think of randomness but okay since they're the 'same.' - There're not, and you might end-up with nothing. Next, refer to page 15 -

    BTW - ALL day I have the after-the-fact -> Please Help Me I bought RAM one before...one now... Heck, I've seen 2 Tri-Channel kits get scrambled and didn't work together until I told the OP to look at variations & S/Ns. Trust me now, and be relieved later.

    My recommendations for 1600 MHz DDR3 that are Certified to work with your MOBO:
    G.SKILL 4GB (2 x 2GB) DDR3 1600 (PC3 12800) Dual Channel Kit F3-12800CL9D-4GBNQ http://www.newegg.com/Product/Product.aspx?Item=N82E16820231193

    G.SKILL ECO Series 4GB (2 x 2GB) DDR3 1600 (PC3 12800) Dual Channel Kit F3-12800CL9D-4GBECO http://www.newegg.com/Product/Product.aspx?Item=N82E16820231319

    1333 Mhz:
    G.SKILL Ripjaws Series 4GB (2 x 2GB) DDR3 1333 (PC3 10666) F3-10666CL8D-4GBRM http://www.newegg.com/Product/Product.aspx?Item=N82E16820231310

    G.SKILL ECO Series 4GB (2 x 2GB) DDR3 1333 (PC3 10666) F3-10666CL8D-4GBECO http://www.newegg.com/Product/Product.aspx?Item=N82E16820231317
  4. I would probably go for the
    G.SKILL ECO Series 4GB (2 x 2GB) DDR3 1600 (PC3 12800) Dual Channel Kit F3-12800CL9D-4GBECO
    looks the best with 9-9-9-24-2n timing
  5. I would agree with the F3-12800CL9D-4GBECO - I prefered to give you options -> $.

    Good luck and I hope I answered all your questions!
  6. Thanks for the help! I've decided to just shell out a few extra bucks and go for G.SKILL Ripjaws 2x4GB 1333
