hello!
I have a macbook pro 15" early 2011 has 4GB of RAM 1333ghz (if not mistaken).
I would like to buy two 4GB RAM, what brand do you recommend? the ghz must be 1333 or even higher?
thx!
MacBook Pro (15-inch Early 2011), Mac OS X (10.7.3)
Your RAM specs are listed below.
Maximum Memory 16 GB (Actual) 8 GB (Apple)
Memory Slots 2 - 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM
The link below is highly recommended for RAM on the forum
It has to be 1333, not more and not less.
And you can go to 2x8Gb that is 16Gb.
I have bought from Crucial, but others are good too.
If you wish you can use this utility http://www.crucial.com/systemscanner/MacOS.aspx
ok i undestand that the RAM must be 1333ghz. but now i have 4GB RAM (two RAM of 2GB), i know that the maximum for my model is 8GB (two RAM of 4GB), is it right?
@Walter con te posso anche parlare italiano?
Di corsa ! Of course.
Ti scrivo esattamente da un MBP early 2011 e come vedi va con 16gb.
E' uno schermo HD opaco ma non credo che cambi qualcosa.
Per sicurezza fai girare il check che ti ho segnalato da Crucial.
La questione 8 - 16 GB mi ha fatto perdere non poco tempo. Molti spiegano che Apple è prudente a indicare 8 mentre invece va a 16. Io ti confermo 16 e ho anche una interpretazione:
Qui ci sono le specifiche

C'è una riga che recita:
4GB (due SO-DIMM da 2GB) di memoria DDR3 a 1333MHz; due slot SO-DIMM supportano fino a 8GB
che secondo me si puo interpretare ..... fino a 8GB ciascuno.
Ciao

ok! constatato che monti 2 ram da 8GB 1333ghz la domanda è: dove le hai comprate, che marca e prezzo?
poi leggevo qui: http://www.macitynet.it/articolo/Memorie-da-1.600-MHz-la-prova-di-Macitynet-su-M acBook-Pro-2011/aA60595
questi addirittura consigliano di usare le 1.600ghz...che ne dici?
Io non mi fiderei a cambiare la frequenza. Non ne capisco abbastanza. Se il "sistema" va ad una frequenza non credo che mettere un componente più veloce possa dare risultati. Magari va tutto nello stesso modo ma se si blocca ? Le RAM credo siano Kingston, sinceramente non ricordo. Le ho prese in Germania in un Media Markt o Media World per circa € 120 entrambe (erano confezionate assieme). Le ho trovate per caso in uno dei miei viaggio. Purtroppo (per noi 😢) da loro si trova tutto.
I say that the correct RAM specifications for a 2011 MBP are: 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM. It would be foolish to deviate from these specifications. Even if faster RAM were to work in the MBP, it would be downward clocked because the 2011 MBP cannot support faster RAM. Thus it is pointless to consider any thing else than what Apple calls for.
Ciao.
OWC and Crucial are the two best sources for Mac compatible RAM.

ok! i'm agrre for have the same ghz (1333ghz) but @OGELTHORPE what do you think about 2 RAM of 8GB (16GB total) on my macbook pro 15" i7 early 2011?
@Walter credimi non so cosa fare... avevo pensato di prendere queste: - what do you think about this?:
An early 2011 MBP will support 16 GB RAM and since it is relatively inexpensive, I suggest you do it. I have installed it in my late 2011 MBP for less than $100.
Remember that it will only be useful if the given situation requires more than 8GB RAM. RAM not being utilized, is useless.
The Kingston RAM looks like it has the correct specifications. I still have a preference for Crucial RAM, which came in my MBP and that I replaced with two Crucial 8GB chips. I found my Crucial RAM on Amazon. Macs have a reputation for being very selective about RAM.
Ciao.
which ram do u prefer: kingoston, corsair or crucial?
Crucial.
Ciao.
Crucial mi piace.
so are you agree if i buy 2 ram of 8gb (16total) 1333ghz?
-but on amazon i don't find nothing with this characteristics...-
Amazon (US) has Corsair "Mac Memory" that meets the 204-pin PC-10600 (1333 MHz) DDR3 SO-DIMM specifications - and Amazon has Crucial, too, it seems.
You might be able to purchase from Crucial's UK website, as well.
Good luck,
Clinton
