Introduzione

L'aumento della memoria RAM garantisce un notevole aumento della velocità.

    • Rimuovi le dieci viti seguenti:

    • Tre viti con testa a croce Phillips #00 da 14,4 mm

    • Tre viti con testa a croce Phillips #00 da 3,5 mm

    • Quattro viti con testa a croce Phillips #00 da 3,5 mm con spallamento

    • Quando sostituisci le viti più piccole, allineale perpendicolarmente alla lieve curvatura del case (non vanno giù verticalmente).

    How much weight can I save by removing the optical drive?

    gunes314 - Replica

    You can save a lot of weight if lets say your installing a solid state drive or putting in a second hard drive but if you know that you use the CD/DVD disc drive a lot then you might just want to leave the drive alone.

    Tip: Use one of those weekday pill holders to have a cheep way to store screws you remove and each day of the week can be for different sizes or parts. It has been handy to have (much less expensive than the magnetic mat.

    Hello, where can I buy the screws I need in case I lose one of them?

    taylornya - Replica

    I have one stripped screw... How opening without drill it?! Any suggestions please?

    rodrigosady - Replica

    I also stripped a couple screws. I wasn’t able to open it up without drilling. After drilling the heads and removing the cover it was easy to hacksaw the tip and unscrew with a standard driver.

    Michael Wilkens -

    My top tip - make sure you buy good quality Phillips screwdrivers and a magnetic holder. Cheap screwdrivers won’t get the screws undone safely. Without a magnetic holder you have no chance of getting the tiny crews in and out safely.

    jeremyyoung - Replica

    A good Phillips 00 is your friend here. Also, when reinserting the screws, gently start anticlockwise and you wil feel a click at the start of the thread. This tells you you’re in the right place and less likely to cross-thread through force in the wrong place.

    Is this step of removing the battery connector required?

    manodh - Replica

    yes - as with disassembly of any electronic component you have to remove any power source. You don't want to accidentally turn the Mac on

    khull -

    Prying the battery connector off does not take much force. I did exactly what the guide suggested (walked it off back and forth) with the spudger without any problems. Just be very gentle, much like with anything inside laptops, they are very fragile and need to be worked with carefully. A+ instructions, battery replacement was a success.

    aekinaka - Replica

    Be patient on disconnecting this one. It worked for me step by step, little by little.

    That's a good tip

    Anrothan -

    Great tip, I did that too

    Ahmed Mahran -

    One other note: The screw heads fit flush with the curvature of the case -- which means that they aren't exactly horizontal. In other words, they aren't perpendicular to the table that the computer is resting on. Don't try to force them straight in vertically, because you'll risk cross-threading them. (nearly ruined one screw hole myself!)

    lelandjordon - Replica

    On my MacBook Pro, the connector seems to be an integral part of the battery.

    After replacing the RAM my macbook did not start anymore. Only if I take out one Ram it works. Does anyone knows why.

    joelcroese - Replica

    Hello Joelcroese, have you a issue about your problem, because i have actually this problem ? ... Thanks for your feed back.

    Remy Duprat -

    Make sure both your RAM chips are running at the same speed - don't know about the Macbook but it will cause other machines to not recognize the RAM at all or only pick up one stick -

    melindaruth -

    Is the channel configuration of your ram sticks correct? Mac needs 9-9-9-24 channel configuration. Something like Corsair Mac Memory or the kit that iFixit provides are in the correct channel configuration.

    Seji the veggie - Replica

    Just to point out:

    1. Do not press again the locker.

    2. Changed the bottom RAM first.

    3. Put nicely, gently to the slot. Cue for you. You must see the label of the manufacture.

    4. Close everything.

    5. Switch the Mac and check "Finder>About my Mac" show the correct RAM.

    Thank you, Phillip! I have now (just recently) used FOUR of your guides—1) HARD-DRIVE replacement, 2) hard-drive CABLE replacement, 3) BATTERY replacement, and 4) RAM upgrade installation—to successfully refurbish my daughter’s late-2011, 13.3-inch MacBook Pro and, thereby, hopefully, add a few more years to its useful life. Thanks, again!

    Sincerely,

What kind of ram should I buy? DDR2 or DDR3?

Jason Moon - Replica

It takes only DDR-3 RAM.

oakdragon12 -

Is a 8gb early 2011 macbook pro maxed out, or can I upgrade to 16?

I'm asking because I read in http://www.crucial.com/store/mpartspecs.... that it can actually take 16gb. Thanks!

C Eyzag - Replica

Yup! I upgraded to a 16 GB DDR3 Corsair mac memory kit from Newegg and it works like a charm. I got this kit: https://www.newegg.com/Product/Product.a...

Question - my MBP currently has 4GB RAM. Is there a 2nd RAM slot that will allow me to increase my RAM by adding 4GB or 8GB. Or do I need to replace the current 4GB with a new 8GB module?

Steve K - Replica

Your MBP will have two chip slots that are stacked on top of each other. When you remove the top chip, you'll see the second chip sitting below it. It is best practice to replace both chips with the same amount of memory. So your current computer should have 2 - 2gb chips, so if you want 8gb total, you would install 2 - 4gb chips. Or for 16gb total, 2 - 8 gb chips.

Drew Davis -

Thanks for the straightforward and excellent guide!

Melissa Smith - Replica

I followed instructions & pushed power button. My screen is dark & computer is beeping at me. Suggestions on what I did wrong?

mjsinkc - Replica

if its a black screen and 3 beeps it sounds like your RAM did not get seated all the way. I would take them out and reinstall them.

Matthew -

Officially, the memory speed of a early 2011 MBP is 1333MHz (cas latency 9) because the that’s the CPU:s highest supported memory speed. Memory voltage is 1.5V.

And, officially, the max memory is 8GB (2x4GB).

So, if you would follow that, the best you could do would be 2x4GB 1333MHz.

It will however work perfectly fine with 16GB (2x8GB).

It is also possible to run 1600MHz (a.k.a. PC3-12800) memory, even though that’s not officially supported.

The thing is, most 1600MHz modules run at CL11, which will mostly negate any gains from the higher frequency. So, what do you do?

You go for 2x8GB 1600MHz CL9. Nowadays, these can be found, even the DDR3L type, at decent prices.

Suggestions? Kingston HX316LS9IBK2/16 or G.Skill F3-1600C9D-16GRSL, which is just that: 2x8GB 1600MHz CL9 DDR3L. Works perfect in a early 2011 MBP.

This will have a performance gain: My benchmarks showed a +25% increase in memory bandwidth with 2x8GB 1600MHz CL9 over the stock 2x2GB 1333MHz CL9. Kinda cool :)
