Should Corsair Memory [CMS016GX3M2A1333C9] compatible for macbookpro 2011?

Looks good. This is what the specs. should be: 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM and that looks to be the same.

Ciao.

Yes. Unless the RAM is faulty from the start, you shoud be fine. OWC and Crucial, perhaps the two most reputable vendors of RAM, sell 16 Gb upgrades.

Whether one needs 16 Gb of RAM in a MBP is a different question. If the fiscal expenditure does not frighten you, it certainly will not do any harm. Understand that there will be benefit in a few situations when you run power/RAM hungry applications. Normal 'light duty' applications, ie. web browsing, text editing, email and the like , there will be no change. In those cases 4 Gb or less is ample.

Ciao.

Oh, yes. Just beware that as soon as you are thru installing them and you eagerly push the power button, disk space, quite a bit of disk space will mysteriously vanish. The room taken by both the sleepimage and the swap areas (even if these won't be used much) will have to expand accordingly. You have been warned!

Not sure about that part number. I just searched corsair's website for that and came up with no hits.

I just added:

Corsair Mac Memory — 16GB Dual Channel DDR3 SODIMM Memory Kit (CMSA16GX3M2A1333C9) was $199 US a month ago.

to my Late 2011 MBP. Works good. And yes, for now overkill, but experience over the years teaches me to max it out if you can, because down the road as memory specs change it can get harder to aquire the correct additional memory. And we all know that the operating system and apps only get larger and larger, requireing more resources to run.

Courcoul, greeting friend: Are you suggesting that there will be negative impacts on performance, ie. such as response time or just available storage?

Ciao.

I'm suggesting that if his HDD is as many, chockful of stuff, when the Mac gets wind of its new and vast expanse of RAM, the disk is gonna overflow and then you may even have a crash or two. Take that as a performance hit! So he better plan ahead and make sure there's plenty room BEFORE touching the screwdriver.

Once that is safely sorted out, there will most certainly be joy and dance when paging drops to zero and the Mac seems like it were brand new. ESPECIALLY if the move is from a piddly 4GB world. Just had that overwhelming experience, and I only moved from 4 to 8!

Courcoul, greetings friend; So you are saying that adequate space be provided in the internal HDD prior to the installation og the RAM. Presumably this could be done by reducing or eliminating data such medical/scientific files pertaining to anatomical subject matter or other items.

Ciao.

Yeah, or move the pron stash elsewhere. Calculate how much more RAM is in there, multiply by al least 3 and make sure there is at least that much available.

For example, a 4 to 16 upgrade: 12GB added => 12GB extra for the sleeparea + 2*12GB for the swap areas that the system will add even if not used = 3 * 12 = 36GB free to be on the safe side.

TANSTAAFL rules!

Courcoul, greetings friend; I appreciate the education. More information to clutter my mind.

Best regards.

Ciao.

PS. To be grammatically correct, should it not be TINSTAAFL?

djousma, greetings: Let me bring up a minor point. The RAM upgrade that quote at $199 was at one time about $1500 and I would not be surprised if in a year it may be $100 or less. Buying for the future is a valid but I would say an uneconomic strategy. I still can get RAM for my 2006 MBP and it costs about $22. I made the upgrade immediately when I got it in 2006 and paid $150!

Ciao.

Problem is you can't "control" either the sleepimage or the swap areas. Those spaces are automatically managed by the OS and are invisible to the user. Only in the server version of an OS do you get some configuration control, but not in desktop versions.

It seems to follow an inverse bell curve. In the beginning, when the part is just going into mass production, prices are high. As time goes by and everyone begins making them, price drops. Then, as the computers that use it go out of style, or of order, fewer makers cling on and price starts to go up again. For instance, try to get any type if SIMM module, that were the kind used by computers in the late 90's. If you manage to find, say, a 512MB stick, it will cost more than your 4GB set of DIMMs.

BTW, mailman just dropped off my Corsair 8GB upgrade and I couldn't be happier. Lion is definitely meant to live with this config. Have loaded the entire MS Office suite, VirtualBox running Win7, about 4 browsers, iTunes and played a movie, without managing to get the OS to swap at all! All for $45, plus $12 shipping.
