DesktopsAll the memory is in the slots, there is none permanently on the motherboard. You remove what is in the slots and you have Zero, then add two 8GB devices and you have 16GB.
Apple will not help you if you run into problems, so be sure to do business with a Vendor who can provide support.

Jun 8, 2014 10:26 PM in response to Mark Andrawesby estton,Well Mark, your MBP comes with only two modules (or ram spaces), so if you have a 4GB ram Mac, that means that you have 2 memory cards, each one with a 2GB capacity, or in tech words, 4GB Kit (2GB x 2). That said, you can replace each module with the ram of your convenience, in this case the upgrade you want is an 16GB Kit (8GB x 2). So in each module you must put an 8GB memory ram. Is better when your two memory spaces are fill with the same GB capacity, example; 2GB x 2, 4GB x 2, 8GB x 2, 16GB x 2 and goes on.
Hope my answer will help you.

Mac OS Xidstein3004,
Although the 2011 models are spec'ed for 1333MHz RAM, many people, it seems, have purchased the 1600MHz with no problems. While a few people have had problems. As for myself, I stick with what Apple has specified so when I purchased my Crucial RAM, I bought the 1333MHz.

Aug 4, 2014 8:33 AM in response to OGELTHORPEby ZenStardust,Legend thank you, and I'm guessing I don't need to by Corsair ram to make it work? (meaning I can buy another mac compatible brand)
And will 1600Mhz work even the Macbookpro standard is 1333 Mhz?
Thanks again !

It might. If I were installing 1600 MHz RAM in my 2011 MBP, I would purchase it from OWC. They are the only vendor that I know that has tested it, so RAM from them will be compatible.
Ciao.

Sep 8, 2014 11:55 PM in response to clintonfrombirminghamby alenyc,Hi Clinton,
So I've been reading through this thread and there are two items that spark my interest:
- Crucial SSD 512GB
- Crucial 16gb (2x8gb) ram
I'm wondering if I need both, or if just a ram upgrade will be enough for me? I don't game but I do deal with large data sets and a plethora of files open at one time which does slow down my macbook pro 13'' (late 2011) with SATA III.
What do you recommend?
Alessandro
P.S. I don't mind spending the $370 but I just want to make sure that it's a smart choice!
P.P.S Do you recommend the MX100 or M550 if I do get the SSD?

Sep 9, 2014 12:10 AM in response to alenycby clintonfrombirmingham,I highly recommend Crucial RAM and SSDs - I've four Crucial SSDs and have had 16GB of RAM in my machine since shortly after I purchased the computer,
You don't say which machine you have, but you can go to the Crucial website and click on the Crucial System Scanner tab and download a small app which, once unzipped and run, will report your specific model back to Crucial and you'll be offered the choices of upgrades that are right for your model.
I would recommend the 512GB M550 model - I jumped the gun and purchased a M500 960GB model only two weeks before the M550's were introduced and I hate that I 'lost' that 60GB of storage with the M550 1 terabyte model!
Call back with any questions,

Sep 9, 2014 9:26 AM in response to clintonfrombirminghamby alenyc,I have a Late 2011 Macbook pro 13. I think I will buy both then.
I have one more question, I've been hearing that the Crucial is safer than the Samsung SSD and has some sort of power loss protection. Does this mean that SSDs are less safe to save your data than HDDs? Are there any risks in using them?
Thanks!
A

Sep 9, 2014 9:51 AM in response to alenycby clintonfrombirmingham,Samsung SSDs are just fine - at least the 840 and EVO models. I just prefer Crucial, personally. They are very, very Mac-friendly.

Sep 9, 2014 12:04 PM in response to clintonfrombirminghamby alenyc,I can tell that and I will get the Crucial SSD. Can you confirm that there are no risks using SSDs?
