    • The lower case is constructed of rubber-coated aluminum. Do not excessively bend the aluminum during removal, as any permanent deformation will cause tolerance issues after reassembly.

    • Slightly lift the lower case near the vent opening.

    • Continue running your fingers between the lower and upper cases until the upper case pops off its retaining clips.

    • The location of these three clips is shown in the third picture.

    • For precautionary purposes, we advise that you disconnect the battery connector from the logic board to avoid any electrical discharge. This step is optional and is not required.

    • Use the flat end of a spudger to lift the battery connector up out of its socket on the logic board.

    • It may be easier to use your fingernails to lift up on both sides of the connector.

    • Release the tabs on each side of the chip by simultaneously pushing each tab away from the RAM.

    • These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

    • After the RAM module has popped up, pull it straight out of its socket.

    • Repeat this process if a second RAM module is installed.


To reassemble your device, follow these instructions in reverse order.

I have been running 2 x 4gb chips for the last two months in my unibody white late 2009 macbook with no probs. The only difference from the standard ram chips is a massive speed boost!

Hi I'm currently installing 16gbs of ram, that is supported by my Macbook 2010 White unibody, however the mac is not reading the full amount installed. i have gotten 10gbs working, by installing one of the new 8gbs sticks, and the old 2gb. Both of the new sticks of Ram have been tested, by simply swopping them out with each other, but when combine the full 16gb sends a error code, 3 beeps with a 5 sec in between. Both ram slots work, all four sticks of ram work, the two 8gb and the old two sticks of 2gb, and computer runs right now at 10gb, so there is proof that it is supported. please help me, i am stuck.

You have two different types of ram there... One cannot be read by the Mac book for some reason because of the speed or type.

Hey Skyler, I'm having the same issue. It appears that if you have at least one DIMM of 1066MHz RAM, the machine will be able to boot and clock-down faster RAM so that both DIMMs are running at this MacBook's maximum 1066MHz speed. I suspect that because both of my upgraded DIMMs are faster than 1066MHz (1300MHz), it is preventing the machine from being able to boot, and it's subsequently unable to remedy the RAM speed discrepancy. In my case, I get a single beep every 5 seconds when trying to boot which means "No RAM Installed"

The solution would be to return the faster memory and buy 1066MHz speed RAM, although now-a-days that's more expensive than buying 1300MHz or 1600MHz RAM when you're looking for 16GB. I guess you can also leave the mismatch DIMMs (10GB) if you need to, but it's definitely not optimal.
