3x8gb 1600 mhz cl9 vs 2x8gb 2133mhz cl10

So I'm upgrading my old i7 920 build. It's still going strong, OC'd to 4.2 ghz.

Now I only have 6gb of ram (3x2gb) running at 1700 mhz, 9-9-9-24.

Problem is bf4 is raping it.. Ram usage tops out around 97%. I haven't had a crash because of it yet but I assume that's because I have a large pagefile it uses.. This obviously is slowing down my fps though.

I want to upgrade but have a dilemma, triple channel kits are almost non-existent anymore.

I've narrowed my choice down to this:

3x8gb 1600 mhz cl9 Corsair Vengeance = $190

Or

2 x 8gb 2400 mhz cl10 corsair dominator platinum $250

Now my confusion is, if there is going to be any real world difference in gaming if I OC my ram up to 2133 mhz with the dominator platinum? And if there is would it then be held back by the fact I would be running them double channel?

I can't figure out if 2133 mhz cl10 in double channel is worth it against 1600 mhz cl9 in triple channel.

Unfortunately I can't get the dominator platinum as a single dimm to run it in triple channel so I'm limited to buying 2x or 4x. The vengeance is available as single channel so I can buy 3 sticks.

Price difference is $60 between the two options.

  1. You can't switch between triple and dual channel, the motherboard is either single channel, dual, triple or quad.

    Right off the bat, stick with 2x8GB, but you don't need 2400MHz RAM, that is pointless and won't see any gains noticeably. Just get a good brand of 1600 2x8GB.

    What motherboard do you have? We want to make sure we get you the correct RAM if you're dual or triple. Running 3 sticks in dual channel isn't a good idea.

    Thanks for the response.. mobo is an asus p6t deluxe.

    It's the i7 920 cpu and the motherboard is triple channel ddr3.

    It can run as triple channel or double channel.

    As you said the performance gains are negligible with 2130mz/2400MHz so I assume the 5% performance increase running in triple channel is the most beneficial.

    Upon looking at the ram again I now have two options,

    The 24gb (3x8gb) 1600mhz is actually cl10 and costs $190.

    Theres also 12gb of the same type (3x4gb) 1600mhz that is cl9 and costs $85.

    The reason I'm wary, I mean I know I don't need 24gb for gaming but 6 years ago when I upgraded to 6gb i was told that was overkill.. Now it's not.

    I'm would like to think games will never use more than 8gb so surely the 12gb at cl9 is the most logical choice? Saves me $105, runs a tighter timing at cl9..

    What do you think?

    Well it's like you said, 5-6 years ago we didn't think games would use more than 3-4 tops, now we have BF4 pushing up there lol I would think 12GB would be fine, but it depends on how long you plan on keeping this amount of RAM, and if the extra money is worth it to you.

    You always go with the 24GB now, and do a RAMDisk or something. But again, it's up to you and your money. If the money isn't a problem then why not, and get you a fast, good size RAMDisk goin lol but if not, 12GB would give you double the RAM and you would be twice as well off as you are now.
