    Quick question...hopefully...

    Which is better to get?

    1) 16GB - DDR3 1600MHz Dual Channel Memory (4 SODIMMS)

    OR

    2) 8GB - DDR3 1866MHz Dual Channel Memory (2 SODIMMS)

    I am a 3D artist and am purchasing a new laptop to function as my primary workstation. I will need to render (for several hours at a time) and run particle and fluid simulations. I'm customizing a new laptop, but when I got to the RAM choices I wasn't sure if the higher Mhz (1866) would be equivalent to more RAM (16) at a lower Mhz (1600.)

    Any info is much appreciated!

    If your work involves low memory usage, the 1866MHz RAM will be a little faster. However, if your work could use more than 8 GB of RAM then the excess will be handled by a pagefile, which is much slower than any DDR3 RAM, whereas 16 GB of slightly slower RAM would not have to resort to that and thus offer faster overall performance.

    I don't know much about 3D rendering and particle simulations, but my guess is that they would take advantage of more than 8GB.

    You might also consider getting the minimum RAM option factory-installed and buying 16 GB of 1600/1866 DDR3 and installing it yourself. A lot of the time that will save you tens or even hundreds of dollars.

    Oh, and depending on what CPU you're getting, it may or may not be able to use RAM at speeds over 1600MHz, so that's worth asking about as well.

    3D modelling and simulations can definitely benefit from more than 8 GB of RAM. Also, in most cases, more RAM is better than faster RAM; the latter will only make a difference in synthetic benchmarks.

    I'd definitely recommend getting 16 GB of RAM. Or better yet, as the above poster mentioned, get the minimum amount of factory RAM, buy 16 GB of RAM from a quality brand (Crucial, Corsair, Kingston, Mushkin, etc.) and install it yourself.

    I add that you can buy Corsair 1600 RAM and OC it to 1866. But even without OCing Corsair iss the fastest 1600 ram. 44 bucks on Amazon for 8gb now. grab till you can.

    Depending on the extent of your usage, 3D modeling and rendering can take advantage of more than 8Gb.

    Higher frequency RAM sticks can even hardly make a difference in benchmarks(usually 1-5%) compared to lower frequency sticks, in real world scenario, the difference will be a lot smaller than that, there is no way you can perceive such a miniscule difference. 16Gb RAM will give you far more benefit if your 8GB RAM ever runs low.

    If you going to do lots of 3d modeling/rendering, fluid/particle simulation, make sure you get a i7 quad core(model number ends with QM, like i7-2630qm, i7-2670qm), they will significantly hasten the rendering process, as well as helping the simulation.

    16 GB 1600MHz for shure.

    You won`t have any performance increase at all with going from 1600 to 1866MHz RAM. 3D software take a huge toll on RAM which means that more RAM is always better.

    I vote for 16GB as well, even if your modeling software isn't that much of a RAM hog (it'll be a RAM hog, but how much will vary), you won't have to close your other apps just for the software to run properly.

    Particle and fluid simulations are definitely RAM hogs, depending on the software you use and precision you need/want you can easily use up most of 16GB. I mean i went over 12GB just by simulating a rectangular duct once because i had an insanely fine mesh. That's a bit extreme, but should you ever find yourself in a similar case, you'll appreciate the extra RAM or you'll have to go through the trouble of finding a lighter solver algorithm.

    Corsair or Kingston XMP 1600 and flash to 1866MHz :p

    Thank you everyone for the information. One of the things I love about this board is that I can always find quick, reliable information.

    I do have three other questions. I did plan on buying the min RAM set and then purchasing the RAM I want and installing it myself. One of the other options for RAM is to bump it up to 32GB of 1600Mhz with 4 sodimms. I figured that if I had the option to buy 32GB of RAM then the CPU I chose should be able to run it. So for my question...

    Would you go with:
    Mushkin Enhanced Essentials 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1333

    OR

    CORSAIR 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1333

    btw...is laptop memory 204 pin and desktop RAM 240pin?


    Last question:

    I was wondering about which one to get and haven't followed notebook CPU's since I bought my last notebook 4 years ago. I want to obviously get the best value, but don't want to overspend hundreds of dollars if I will only see a small fraction of improvement.

    I had decided to get this one until I read lidowxx's post:
    2nd Generation Intel® Core™ i7-2670QM, 2.2-3.1GHz, (32nm, 6MB L3 cache)

    But I'd like to know if getting this one is really worth $160 more?

    2nd Generation Intel® Core™ i7-2760QM, 2.4-3.5GHz, (32nm, 6MB L3 cache)

    I was thinking all along that more RAM would be the answer instead of faster and less RAM so I'm glad that I was on the right path.

    As always...thanks again for any info you can provide.

    Unless you need the extra features provided by the 2760qm or the few minutes per hour of rendering that you'd save are enough to justify the cost, then yes. Otherwise, stick to the 2670qm.
