简介

升级内存并且瞬间加速电脑。

  1. 松开固定iMac底部的三个十字螺丝。
    • 松开固定iMac底部的三个十字螺丝。

    • 这些螺丝将保留在检修门上。

    • 从你的iMac拿开检修门

    • 重新组装时,将检修门松开,并将其与iMac外壳上的检修门口对齐,然后再拧紧螺钉。

    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.

    • 把黑色的塑料拿出iMac以便于把内存芯片从内部拿出。

      • 内存模组会牢固的放置在里面, 可能需要使用一些力气才能移除。

    • 使用你的手指来把内存芯片从内部拿出。

    • 如果需要的话,在其他的内存模组上重复这个步骤。

    How many 4MB cards can I install?

    nowsc - 回复

    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 - 回复

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

Interestingly, the mid 2011 iMac 27 inch also goes to 12GB!

I originally thought I'd be upgrading to 8GB today but found 4 slots instead of 2 :-)

As long as the two front (close to the screen) slots are paired with the exact same RAM config.

For example:

Two front slots Apple 2GB chips = 4GB.

Two rear slots, Crucial Lexar 4GB chips = 8GB

Total 12GB

Hoorah no waste and more RAM, come on Lion... I'm Ready!

Be sure to really push the RAM all the way into the socket. I had a "no RAM" error beep when I first booted up my iMac after doing this. Just an extra two millimetres was all it needed to be properly installed. It can be quite tough to get in.

Hi,

I've got a 2309 and just received my two additional 4GB RAM Cards. Put them in and I can say that the speed improved (now with 16GB). Not dramatically, however, some applications did always show the little rainbow disc when my Mac was "thinking". This is now gone.

I am on OS X 10.9.5 still and the whole Mac feels as if it can "breathe" more lightly with the additional RAM.

Thanks!
