Accessing the RAM in this computer is straightforward and requires minimal disassembly.

The Mid 2009 2.13 GHz model is the only A1181 MacBook that uses PC2-6400 RAM.

  1. MacBook Core 2 Duo RAM Replacement, Battery: step 1, image 1 of 1
    • Use a coin or spudger to rotate the battery-locking screw 90 degrees clockwise.

  2. MacBook Core 2 Duo RAM Replacement: step 2, image 1 of 1
    • Lift the battery out of the computer.

  3. MacBook Core 2 Duo RAM Replacement, Memory Cover: step 3, image 1 of 1
    • Unscrew the three evenly-spaced Phillips screws from along the rear wall of the battery compartment.

    • The screws are captive to the metal memory cover so you cannot lose them.

    • Using The Flexible Extension sold by iFixit will help with this step.

  4. MacBook Core 2 Duo RAM Replacement: step 4, image 1 of 1
    • Grasp the right end of the L-shaped memory cover, then pull it towards you so it clears the battery compartment opening.

    • Lift the memory cover up and out of the computer.

  5. MacBook Core 2 Duo RAM Replacement, Pull the RAM out: step 5, image 1 of 1
    • Pull back on the metal lever and slide the RAM chip out from its compartment.

    • Unlike the iBook line, the MacBook has two SO-DIMM RAM slots.

    • When installing RAM, be sure to push the chips in firmly or else the computer will not register them.

another great tutorial ~ this was very easy, took maybe 10 minutes max, and now i have a noticeably faster computer. i agree with the previous comment that you need to push the new ram in rather firmly.

Success! Fifth time was the charm! I tried to move up from the original 2x1Gb RAM configuration in my MacBook 6.4 Ghz Core 2 Duo to 6 Gb RAM (1x4 Gb + 1x2 Gb, all from iFixit). Followed instructions exactly after grounding myself several times etc, put the 4Gb module on the left and 2 Gb on the right but got the dreaded "three beep." Tried re-installing w/ the 4Gb module on the right--no joy. Tried re-installing old 1+1; no problem, so obviously I was seating the modules correctly. Fourth time: Just installed the new 2 GB and left on of the old 1 Gb--success! The 4 Gb module seemed to be the problem. Tried one more time--attempt number FIVE. Put the 4 Gb back in for the third time (in place of one of the old 1 Gb of course--SUCCESS. I heard a different click this time too. Anyway--I now have six times the RAM I originally had installed--Yea! Thanks, iFixit! Now, I'll work in my iMac!

Ok - I took your lead and started trying all the different combinations I could create and finally one just worked. So don't give up people - just use process of elimination and you will find the right combo! I did try one new, one old 3 different ways before it took.

Nellie -

I am trying to replace the original RAM (1GB on each side) with two new 2GB chips on each side (the PC2-5300). I keep getting the 3 beep response with both or just one new chip. When I put the old ones back in everything is fine. Any suggestions?

someone told me that the macbook 2,1 could take 4 gb ram but only make use of 3 gb.... ?

can someone verify if this is true ?? and is it then posible to combine 1gb and 2gb of 2ddr pc5300 ?
