按照这个指南来移除、替换或升级在你的27英寸 5K iMac上的内存

  1. 在保持显示器稳定的同时,使用一个东西来压住位于电源端口上方的内存门释放按钮。 你可能不得不用力地按压它,直到它的底部从iMac的后面弹出大约0.25英寸(0.635厘米)。

  4. RAM托盘被锁定在固定的位置,有两个灰色的标签。 用你的拇指或食指来解锁托盘,把标签向外推,远离内存。 把内存托盘拉出来,然后把它拉到一个接近水平的位置。

  5. 用两只手抓住一条内存,然后直接从内存托盘中取出。 内存模块是有方向的的,因此它们只能安装在正确的方向上。请注意,在移除和重新安装内存时,金手指较短部分的方向。 要安装一个新模块,请将模块插入到托盘中所需的槽内,并将其紧紧地按在适当的位置。把托盘往后推,直到它锁好。

    Mine is flipped so the shorter section of the RAM module is on the right.

    Mine is flipped too… not a mistake, is it?

    Kristi Mathias - 回复

    What do think about extending step4 with the following:

    Please remember direction of shorter section for later installing of upgrade RAM.

    or so ...

    To add:

    The RAM door is not symmetrical. When putting back the RAM door, it should flush with the back. In STEP 1 photo of the RAM door it seems the RAM door is not fully flushed and aligned.

    Hi, how many RAM slots are available. In the system overview there are 4 slots and only 2 of them are used with the current setup.

    big blue - 回复

    Does replacement RAM have to made in “matched pairs”? For example, if I add an additional 32G (2x16G) to the base 8G (2x4G) can the new 16G DIMMS go in any slots or do they need to be placed into specific “matched” slots - (slots 1 & 3 and slots 2 &4)?

    Can I “mix and match” different capacity and manufacturer RAM DIMMS or do they all need to be the same ?.

    richardkpallo - 回复

    From the Apple website for replacing ram in an iMac: https://support.apple.com/en-us/HT201191...

    For iMac’s released 2012 onwards there is no note about the position of ram or matching pairs.

    For iMac’s released 2009-2011 there is this note:

    i5 and i7 Quad Core iMac computers come with both top memory slots populated. These computers will not start up if only a single DIMM is installed in any bottom slot; these computers should operate normally with a single DIMM installed in any top slot.

    Core Duo iMac computers should operate normally with a single DIMM installed in any slot, top or bottom. ("Top" and "bottom" slots refer to the orientation of the slots in the pictures below. "Top" refers to the slots closest to the display; "bottom" refers to the slots closest to the stand.)

    There is a number of comments to say you should stagger the ram and make sure i=identical ram modules share the same DIMM number, not the same BANK number. How to couple RAM Modules in iMac 27?

    Does ram from iMac 27 late 2013 suit these imac or do i need to buy others?

At the end: "To reassemble your device, follow these instructions in reverse and use our adhesive strip replacement guide to reattach the display glass."

This does not make sense for a memory replacement guide.

I made a few changes to the guide to make it more readable. Thanks for the tip!

Miroslav Djuric -

I am thinking about getting me an iMac 5K but not really interested in overpaying for my RAM - can I access all 4 slots in the newest iMac 5K so I could buy the entry level with 8GB and then upgrade it to 32GB myself?

sdjensen - 回复

Yes, but make sure they are the same frequency so there won't be any issues. (1867)

vsomme -

Is it possible for 4GB x 2 model to add 8GB x 2 and having 24GB RAM

christmas - 回复

yes, just make sure they are the higher 1867 frequency ram and you will have the original 4x2 plus your new 8x2 for total of 24gb.

vsomme -

Hey.... when i add new Ram... does it matter go it goes in? what i mean is I have 4 slots.

2gb, 2gb, 2gb, 2gb

Can i put in

2gb, 8gb, 8gb, 4bg ?

thomas - 回复

Mixing and matching is usually not recommended ... even if the clock speed and voltage are the same, it's best if the timings are also the same, and even then, it's not guaranteed that two different sticks will work together. Most of the time they will, but you don't want to be one of the 20% or so where it doesn't.

Kindly advise if this model of RAM will fit in the iMac 5k Retina?

Kingston HyperX FURY 8GB 1866MHz DDR3 CL10 DIMM - Blue (HX318C10F/8)

yahyujee - 回复

no, yahujee, that particular RAM is for desktops (DIMM). iMacs use RAM that is the same size as laptop RAM (SODIMM)

David Farwell -

Hi, How can I tell the frequency of the RAM? The label says OWC1600DDR3S8GB and a serial #. Bill

Bill Tivol - 回复

Hi is - HyperX 32GB (4x8gb) 1866MHz DDR3L CL11 SODIMM - supported by iMac 5k retina 27" i7 4Ghz? thnx

tommy - 回复

Hi the latest imac 5k retina does it use the same method to upgrade ram?

Dinesh Chandrathasan - 回复

Same followup… does this guide apply to the recently released iMac update?

Lee Fuhr - 回复

I see that replacement Ram for 2017 27' iMac from Crucial & OWC are CL17. The iMac comes with CL11. Where can I find the faster CL11 Ram To upgrade?

ron123 - 回复

Please Tell Me:

Can I install only ONE (1) 8GB stick, besides to the original two (2) 4 RAM sticks that came with my iMac 5K Retina 27”? That will turn the RAM to 16GB; the other slot will remain empty for future expansion; is that OK??
