    No it doesn't, and yes i can.

    The 4x4GB dual-channel performance increase will completely nullify any performance gains by getting 1600MHZ instead (not to mention most laptops only support up to 1333MHz) and then there's that whole extra 4GB of RAM.

    And you're not? Ironic considering you're arguing a noticeable difference between 1333MHz & 1600MHz.

    Plus, asynchronous dual channel applies to different capacities, you still need the 4 sticks of RAM for it to work. 3x 1600MHz still isn't going to help you there.

    Keep in mind the OP is specifically asking about 3x4GB dimms, not 2x4GB & 2x2GB.

    In a new Ivy Bridge based notebook, I had the chance to try 2x4GB 1600MHz RAM vs. 2x8GB 1333MHz RAM and I noticed a huge and immediate performance drop when the (16GB) lower spec'd but higher capacity SoDimms were installed.

    The whole system felt sluggish; IE would take a few seconds to display new webpages and basically the i7 3610QM system responded like something from 2007.

    Putting the 1600MHz (8GB total) RAM back, the system felt once again like the 2012 high performance system it is (even with the ancient 5400RPM HDD the system shipped with).

    My advice: keep saving until you can afford the proper rated RAM for your system (I'm assuming this will be going into an Ivy Bridge system, of course). If we're talking about a Sandy Bridge based system, then I'll agree with most here that the 1333MHz SoDimms (16GB total) will be the superior configuration - unless it's installed in a very highend i7 (XM) SB based system).

    Good luck.

    Why would you be assuming this is for an Ivy Bridge system? What has been said where which would give you that indication?

    Also you're comparing 8GB of 1600MHz with 16GB of 1333MHz, it's documented that systems can run slugish if too much memory is installed but unused and I've observed this myself. Not to mention not every chipset or board supports 8GB dimms.

    Where have you seen that 'too much memory makes systems run sluggish'? ROTHFLMAO

    By stating my assumptions, I don't have to care what system is being considered: (especially since none are mentioned by the OP at all) - and my observations stand on their own.

    No you don't. Asynchronous works with any number of sticks. Since there's only two memory controllers having 8GB (2x4GB) in one channel and 4GB (1x4GB) in the other will still be asynchronous. Asynchronous works with single + dual channel and optimizes for use with RAM amount that is dual channel. So in my example 8GB would be dual channel and the other 4GB single. In Intel systems it's called "Flex Memory". In any case it really doesn't matter much.

    Some older controllers run slower when using 8GB dimms, most don't have native support for them. Also from memory the only 1st gen i-series chip which supports 8GB dimms is the i7. 8GB in dimms in general have some compatibility issues and can not simply be used in every system.

    My vote for OP: get whatever is on sale. Seriously. Assuming that your laptop has a dGPU (in iGPU case, 1600MHz might be better).

    Ignoring iGPU, you won't notice **any** difference between the two choices, other than a 4GB difference. Even then, you probably won't max out 12GB (I've tried everything other than some scientific computing and 4+ VMs, which will max that out). 1333MHz and 1600MHz won't matter to you unless you're benchmarking (basically: "I got bigger numbers than you!! So mine's better!!" in my book).

    8GB is MORE than adequate unless you run lots of VM's or have specialized software that needs tons of RAM. 1333 vs 1600 MHz is minor difference.

    I'll repeat again that on an Ivy Bridge based system 1333MHz SoDimms made a new system basically unusable.

    You've been warned...
