Sandy Bridge Memory

16Gb set or 2-8Gb sets.
I want to put 16 Gb of corsair memory in a Asus sandy bridge set up. the 16Gb set is never on sale, but the 8Gb set often is. Is buying two 8Gb sets any different than a 16Gb set. Both are 4Gb sticks. thanks for any help

    On occasion, you might get a kit that isn't compatible or that has one defective stick. The vast majority of the time however, two 8GB kits will work together with no muss and no fuss. Make sure you get 1.5v spec RAM like Corsair's Vengeance kits.

    Out of curiosity, is there a reason why the RAM voltage needs to 1.5 :??:
    I ask because im trying to get myself clued up on RAM as much as possible :)
  3. The Sandy Bridge IMC works best with lower powered RAM e.g. 1.50v, but can run the 1.65v sets. Longterm 'I' would recommend lower 1.50v + SB.

    16GB Sets -> CORSAIR Vengeance 16GB (4 x 4GB) DDR3 1600 9-9-9-24-2N @ 150v:
    Model CMZ16GX3M4A1600C9B http://www.newegg.com/Product/Product.aspx?Item=N82E16820145347
    Model CMZ16GX3M4A1600C9 http://www.newegg.com/Product/Product.aspx?Item=N82E16820145347

    Difference is color, the blue has a $15 rebate.

    Okay, thanks for clearing that up :) .
    Quick question, if i wanted 12GB in dual channel (x2 4GB sticks and x2 2GB sticks all with same speed, latency, volts etc.) would there be any implications in this setup, or would it be okay?
  5. Mixing Size is not the worry, Mixing ANYTHING ELSE is the problem. If both SETS have identical CAS Timings e.g. 9-9-9-24-2T then you'll in theory be okay; edit yeah duh too the Frequency, CAS, voltage, brand, IC's...

    The P67 seems to be REALLY PICKY when mixing even the SAME sets which is why I linked what I did above, I know they work ;)
  6. As jaquith says, just make sure they're the same brand, speed, timings, etc. I have 12GB of G.Skill Ripjaws X 1600 CL9 1.5v in my Sandy Bridge system ... works like a charm.

    Thanks for your advice. I installed 12GB of RAM all with the same specs on my P67 mobo and everythings fine :D
