    Hi, I have a MBP 13 "i5, and I would like to upgrade the ram memory, I saw that there are people who can do the work with 8Gb 1600Mhz.

    But, I saw also, that there are choices of 16GB, and also the 1600Mhz and 1866Mhz.
    I wonder if these kits (16Gb 1600Mhz~1866Mhz) work in my MBP i5 and which would be indicated.

    Thank you!

    Post Script: Is a i5 MBP, I know there are people who gets it with the i7, is not my case... Thank you very much.

    Getting 1600mhz or 1866mhz RAM wouldn't do you any good as the bus speed on this model is 1333mhz and there is no way to overclock the bus to utilize faster RAM.

    If you got 1600mhz or 1866mhz rated RAM and put it in your MBP it would just run at 1333mhz regardless.

    If you can afford 16gb go for it, you can't really have too much RAM. Only reason I could see buying 1600 or 1866 rated RAM is if you found a deal making it cheaper than 1333mhz RAM.

    I also thought that, but I saw people who could make it work:

    I wonder if it would work also with kits and 16GB 1600Mhz or 1866Mhz... :(

    Thanks for opening this topic, i have the same doubt about it :)

    I saw here some macbook pro 13" i5, working with the 1600mhz memory, but i think that is running on the motherboard who has 2 sata 6gbps ports. (hd+dvd)

    i'll follow this topic because i'm interested in put 16gb of ram in my macbook pro, but i want the 1600mhz or 1866mhz,

    And how do I know if my motherboard is one of that who has two SATA 6Gbps ports (hd+dvd)?

    1866mhz works perfect in my 2.3ghz i7, but there is no 16gb for 1866mhz though. I would love to see it soon!

    I was unaware at the time of my post that some newer models support higher frequencies, I since found an older thread on here confirming it and that is excellent news. I'll have to revise my answer to: If you have the cash burning a hole in your pocket get the fastest speed your laptop will accept. :) What is the model number on your laptop, that should help us determine if it can accept the higher speed RAM.

    I found that my MBP is:

    Intel 6 Series Chipset
    Vendor: Intel
    Product: 6 Series Chipset
    Link Speed: 6 Gigabit
    Negotiated Link Speed: 3 Gigabit
    Description: AHCI Version 1.30 Supported

    It should accept the 8GB or 16Gb 1600(1866)Mhz?

    What p4madeus initially said is nonsense there exists no bus except the ring interconnect which is by orders of magnitude faster than any RAM could be.
    Sandy Bridge Memory Controller officially supports 1600MHz, inofficially you can run pretty much anything till 2133 as long as the Voltage is low enough.

    Still faster RAM on a notebook is really not a brilliant idea. It needs a little bit more power and gets you an indistinguishable speed advantage. There is just no difference in speed the CPU doesn't need the faster RAM and doesn't benefit from it in any meaningful way. It is a waste of money. It costs more than double for nothing. Speed difference between 1600 and 1866 is 0% in most cases and 1% in some very few.
    That is like paying twice as much for a car that goes 202km/h instead of 200 everything else the same. Don't look at synthetic memory benchmark those have nothing to do with real world applications.

    Have you done any tests? It actually gives a decent boost to the Intel HD 3000, kinda of like over clocking one's video card memory speed.

    My advice to you is to read this article from Anandtech. After reading the article you'll conclude that it's not worth it to buy expensive RAM.

    1333MHz DDR3 RAM is not a bottleneck for your CPU.

    Will DDR3 8GB 1866 work in an early 2011 Macbook Pro i7 2.2GHz? Whats the bus speed on that? I saw a youtube vid where someone has 1866 and playing Skyrim and BF3.

    The Anandtech article actually states 1600MHz is the sweet spot.

    I agree, whats better, 8Gb 1600Mhz, or 16Gb 1333Mhz?

    I saw the anandtech article, and i didnt notice any bottleneck from 1333Mhz...

    And prices?!

    I'm getting really curious as well now.
    I just got my 13" MacBook Pro yesterday (it's the late 2011 base model) and I'd want to upgrade my RAM to at least 8 GB.

    A few posts back there was said that faster RAM would give a "boost" to the Intel HD 3000, does that mean that my MBP's graphics would perform better, e.g. while gaming?

    Now that'd be awesome!

    I always forget that some people do gaming on a HD 3000.
    Yes it does add bandwidth that a CPU will happily take. Very much depends on the game but some high streaming games like CoD should benefit a lot, high shader games like Crysis probably much less.
    There is a lot of Apples to Oranges comparisons but you still can expect some 10%+ increase in fps with 1866 over 1333. Synthetic benchmarks are the only show some 6% increase, but games like bandwidth usually more than syn. benches. If that is worth the money opposed to the price of 1600 is your decision. In a 15"/17" I think 1866 is a poor idea in a 13" there is some point to it.

    AMD fusion GPUs are very fond of high bandwidth but they are faster GPUs than a hd 3000. It also depends a lot on the game. Shader bound games like BF3, don't get your hopes up.

    Oh no, I'm not that much of a gamer. I'd be pleased if I could play The Sims 3 on it every now and then :D

    So I guess it'd be a good idea to put 1866 MHz DDR3 in my MacBook Pro?

    Sims 3 lol. That game has sys. req. you can almost run it on an abacus ;)
    1866Mhz RAM is a waste of money for it.
    1600Mhz ist much cheaper and not really a whole lot slower.
    I would get 1866 if money is no issues and or you intend to play stuff like HawX, CoD, Starcraft 2 and are happy for every additional frame.
    Otherwise just get 1600Mhz. At least in Europe you get it for about half the money.

    Well, my previous iMac didn't really like it with ± 1.000 downloads in it, haha.
    Guess I'll go for the 1600 MHz then, haha :D

    That's not actually how it works and faster RAM will indeed run at the faster speed and will give you a small performance boost that can be verified via a benchmarking tool like geekbench. However, that performance boost in the real world is basically negligible.

    Get the 1600mhz RAM. You could re-use down the road. There is no sense in buying slower RAM now since price wise, they're all about the same.

    OK, here are my options by prices higher to lower:


    Corsair CMSA16GX3M2A1333C9 - 16Gb (2x8Gb) - 1333Mhz - CL9 - 125 €
    http://www.amazon.es/Corsair-CMSA16...5KZC/ref=sr_1_1?ie=UTF8&qid=1334523529&sr=8-1


    Corsair Vengeance Performance CMSX8GX3M2A1866C10 - 8Gb (2x4Gb) - 1866Mhz - CL9 - 79,90 €
    http://www.pixmania.com/es/es/11485566/art/corsair/memoria-para-portatil-ven.html


    Corsair Vengeance Performance CMSX8GX3M2A1600C9 - 8Gb (2x4Gb) - 1600Mhz - CL9 - 45,90 €
    http://www.pixmania.com/es/es/11485567/art/corsair/memoria-para-portatil-ven.html

    So, whats better? 16Gb 1333Mhz, or 8Gb 1600Mhz or 1866Mhz?! Whats should i do?!
    I play Starcraft 2, World of Warcraft and wanna play Diablo 3 when it comes out... =) By the way.. =)

    Oh god, 8GB 1600 is down to 45USD now!?
    When I bought it last year it was 49USD for 1333 haha
    The 16GB also dropped dramatically.

    I would say go for the 16 since you do some gaming.
    If you open web browsers and emails alot, get 16GB.

    It changes your world from 4GB XD

    I'd skip the 1866MHz one for sure if I were you... Would probably go with 8GB 1600MHz, but that's just me :)
