Introduzione

Questa guida illustra come sostituire la memoria RAM.

  1. Allentare le tre viti con testa a croce che fissano lo sportello di accesso al bordo inferiore dell'iMac.
    • Allentare le tre viti con testa a croce che fissano lo sportello di accesso al bordo inferiore dell'iMac.

    • Le viti resteranno all'interno dello sportello di accesso.

    • Rimuovere lo sportello di accesso dall'iMac.

    • Durante il riassemblaggio, avvitare lo sportello di accesso senza stringere a fondo e allinearlo all'intaglio a taschino nel case esterno dell'iMac prima di serrare le viti a fondo.

    I am going to put a very important comment here. Before you start this process listen to the fans on your iMac do any of them sound obviously loud (think about how quiet your iMac used to sound as a reference) If you notice one or more of them sounding substantially loud compared to the others consider locating a replacement fan prior starting this process. After all if you are already “in the neighborhood” it is a shame to do all this work only to have to disassemble your imac a couple weeks later because you realize the fan is failing. I speak from my own personal learning experience of having to disassembly my iMac 3 weeks later because the HDD was failing and apparently the moving the fan around was just enough to push it to start really under performing.

    I’m not sure why it is necessary to remove the RAM. As far as I can tell, it can remain in place during this procedure.

    • Tirare la linguetta di plastica nera dall'iMac per estrarre il modulo RAM dal suo alloggiamento.

      • The RAM modules are firmly seated and may require a fair amount of force to remove.Nuova riga.

    • Mediante le dita, far scorrere il modulo RAM fuori dall'alloggiamento.

    • Se occorre, ripetere la procedura per gli altri moduli RAM.

    How many 4MB cards can I install?

    None. 4mb ram is too old to fit into any computer manufactured after like 1998.

    @Brett

    I suggest that you learn your unit symbols before you try to appear clever:

    4mb == 4 milli bits

    4MB == 4 mega bytes

    nowsc was obviously meaning 4GB not 4MB, try not to be a dick.

    Take care to note which way out the RAM comes - there is a notch in each RAM and it is not centered, therefore either the notch will be on the left or to the right (depending on which way up you have your iMac). This will make it easier to replace the RAM without damaging anything.

    Mike Haines - Replica

    If damaged the notch inside one pair of RAM slots, is it fixable ?

My iMac 21.5-inch Mid 2011 has EMC 2428, but still directions turned out to be the same.

I replaced the memory in my MacBook Pro, and used the old cards (2x2GB) to fill out the 2 empty slots that apple left empty, doubled the memory of 2 machines for the price of one ^_^

Thanks ifixit team, I did it. It is really piece of cake! Thanks again!

What's the real max capacity for the RAM?

Angel Pimienta - Replica

16 Gb (4 x 4 Gb) DDR3 1333 MHz

Aleksei Marinichev -

16gb according to Apple but 32gb is no problem I would recommend using all identical sticks ie. same manufacturer/speed etc etc.

I have run 32gb for years in that machine With no issues.

Richard Reichle -

Hi, can I add one Ram of 4MB and one of 8Mb?

Cristian Catanescu - Replica

You can but it’s not an ideal configuration

Richard Reichle -

Hi, according to Mactracker the iMac 27 inch mid 2011 can have up to 32GB of RAM. Anyone tested this?

Bård Arve Evjen - Replica

Absolutely I have 32gb and I have used that config since it was new
