RAM imac 27. IMac increase RAM. Memory is never too much
Fusion Drive is a type of hybrid drive developed by Apple. Physically, these are two different devices: a regular large-capacity disk and a separate solid-state media, combined into one logical volume. Fusion Drive combines the advantages of a conventional mechanical hard drive and a solid state drive: high speed with a large amount of available space and a relatively low price.
To build a Fusion Drive, your iMac must have an additional PCIe connector. Unfortunately, if you chose the option without Fusion Drive or SSD when purchasing, this connector may not be available. For example, it is not available on all 21.5 ”iMacs that come with a default mechanical drive. But models with a 27 ”screen have such a connector, and they are waiting for you to put something there!
If your iMac doesn't have one, don't despair. Instead of a single HDD, you can install a SATA SSD and achieve similar read / write speeds.
Can i install a second hard drive in a slim iMac?
If the iMac has an SSD slot, then after installation, you can not combine the two media into one, but use it separately by installing the system on a fast SSD. In this case, the system gains a little in performance, but you will have to regularly clean up and transfer large files to a mechanical disk.
Is it possible to increase the amount of RAM in "thin" iMacs?
Aimak 27 ″: even a child can increase memory. On the back there is a cover, and under it there are 4 slots for expanding RAM. Two of them are occupied by modules, usually 4 GB each. The maximum volume depends on the modification, but 32 GB, that is, 4 modules of 8 GB each, can be delivered exactly. For iMac generations from Late 2012 to Mid 2015, PC3-12800 DDR3 SO-DIMM is suitable, and the newer PC3-14900 DDR3 (Late 2015) or PC4-19200 DDR4 (from Mid 2017).
Aimak 21.5 ″: it's not that simple, but not hopeless. Firstly, not all of these iMacs generally have RAM expansion slots (they are not available in the iMac 21.5 ”Mid 2014 and Late 2015). And in other modifications there are connectors, but it is difficult to get to them: you have to "cut" and re-glue the display, it is not easy to do this work on your own.
The new 5K all-in-one iMac is considered one of the better solutions for their money. However, he has one a big problem - 8 GB of RAM in the minimum configuration, which is clearly not enough for full work... Fortunately, adding RAM to your iMac is pretty easy.
The iMac 5K has four DIMM slots for a total of 64GB. In the minimum configuration, the user gets two 4 GB DDR4 platters, which gives a total of 8 GB. 64 GB is quite a lot, so it is advisable to buy a couple more 16 GB slats, resulting in 40 GB of RAM. This is more than enough to work with Final Cut Pro X and other professional software.
RAM requirements:
SO-DIMMs must meet the following criteria:
- PC4-2400.
- No buffering.
- No parity.
- 204 connections.
- DDR4 SDRAM, 2400 MHz.
How to upgrade the RAM in the iMac 5K 2017
It should be borne in mind that the instructions are only relevant for the 2017 iMac 5K. Although the 21.5-inch model has modules not soldered to the board, it is not so easy to remove the plates and it is better not to do it yourself.
Step 1: Turn off your iMac and unplug all cables including the power cable.
Step 2. Place your iMac face down on a flat surface such as a table. You can use a towel to prevent scratching the display.
Step 3. Press the button above the power connector to open the memory module compartment.
Step 4. Remove the compartment cover.
Step 5. Press down on the DIMM release levers to open the RAM slots.
Step 6. If you bought four modules, you will have to get out the already installed plates. If you only have two new modules, you can leave the existing ones missing. Place the new RAM platters in the appropriate slots. Note that the notch in the module should be closer to the right edge.
Step 7. Return the locking levers to initial position.
Step 8. Replace the compartment cover.
Step 9. Turn your iMac over.
Step 10. Connect all required cables and turn on your iMac.
Step 11. Once booted, go to Apple menu -\u003e About This Mac -\u003e Memory and make sure the system correctly detects all memory modules.
Total
Apple offers an upgrade to 16, 32 or 64 GB of RAM in the iMac for 14,000, 42,000 and 98,000 rubles, respectively. If you order a third-party RAM, you can save about 50,000 rubles.
It's no secret that no matter how powerful your iMac is, after a while, even the most powerful hardware becomes outdated and requires an upgrade.
If a few years ago you were comfortable enough to use this candy bar with 4 gigabytes of RAM, today you can hardly talk about the comfortable use of a computer with such a volume of RAM, because it is barely enough to surf the Internet in a browser with several open tabs.
What can we say about more difficult tasks, such as video rendering. Given the high cost of any Apple technology, not everyone has the opportunity to buy a new iMac.
In this situation, there is only one way out - it is to upgrade the RAM in the iMac.
Which iMac models support RAM expansion?
Apple has often been criticized for lacking the ability to increase RAM for Mac users.
Since the RAM of many Mac models has been soldered to the motherboard. The reason for the dissatisfaction of people was understandable, you are not buying a cheap computer that cannot be accelerated, which means that it will not be possible to fully use it in the future.
RAM frequency and maximum capacity of your iMac
First of all, before you start upgrading your iMac's RAM, you need to find out the maximum supported memory size for your model and the frequency of your RAM.
In our case, we will be upgrading the iMac (Retina 5K 27-inch Late 2015).
Checking the information on the page above, we see that we need a RAM module with a frequency of 1867 MHz, taking into account that the maximum volume is 32 GB.
Which RAM module should you choose for your iMac?
On the official Apple website, you can find the RAM I need, the cost of which will at least surprise most of you.
28,000 rubles for 16 GB, which means for the maximum upgrade of RAM with memory modules from apple you need to pay 56,000 rubles. In such a situation, we recommend that you buy RAM from third-party manufacturers, the cost of which is several times less and will work on your iMac without any problems.
Installing RAM in your iMac
1. The first step is to turn off your iMac and disconnect all cables from it.
2. To avoid scratching or damaging the screen, lay a soft cloth on a flat surface.
3. Gently place your iMac face down on the fabric.
4. Above the power connector, find the gray button that opens access to the memory modules.
5. Place the top cover of the RAM module aside, and to remove the old RAM, press outward on the levers that should release the modules.
6. Pull up on the memory modules to remove them.
7. After all slots are empty, we can start installing new RAM modules. When installing RAM, press the module until it clicks.
8. After all new RAM modules have been installed, fix the RAM compartment inside, also until it clicks.
9. Close the RAM compartment with the lid.
10. Connect all cables and turn on your iMac.
RAM health check
After the iMac turns on, you need to check the new amount of RAM.
We go: About this Mac - Memory.
Make sure that all slots are installed correctly and the system recognizes the correct amount of RAM.

Memory is never too much
I am sure that any Windows PC user knows such a postulate as "there is never enough RAM". Yes, the operating system from Microsoft is a notable "devourer" of RAM, but machines based on Mac OS are no less notable consumers. Of course, the lack of this resource in Apple computers is not so pronounced - there are usually no wild brakes, but the overall slowdown in the OS is not difficult to notice. Applications start up slower, and a rotating icon often appears to indicate that the system is "thinking", etc.
Accordingly, the more RAM a PC has, the better. If the computer was purchased in those primeval times when RAM strips were worth their weight in gold, then now is the time to change them to something more capacious, the price of memory has long been within reasonable limits, although this cannot be said about the original components offered Apple. I don’t know what the “magic” is, but often ordering additional hardware modules from Apple or creating an individual configuration can cost many times more than upgrading the standard model yourself. In addition, custom-assembled Apple machines in Russia, Ukraine and other post-Soviet countries cost truly insane money. This means that we will deal with the upgrade ourselves, especially since this is done very easily, although you should adhere to certain rules, which we will talk about below.
Do you follow safety rules?
These rules are universal for any modification of RAM (and other expansion cards too), whether on a PC, Mac or laptop, regardless of the manufacturer.
Rule # 1 - no static electricity... Static "kills" RAM in the blink of an eye - one spark and the module can be hung on the wall as a sign of a sad reminder of personal carelessness when working with delicate computer hardware. It is necessary not only to remove static voltage, but also, if possible, not “recharge” in the short period of time that is needed to approach the computer. It is worth touching the unpainted metal with your finger, the water tap, or you can lower it under the stream of water. It is advisable to take off woolen socks, sweater, synthetic clothes that are well electrified All this, perhaps, is a kind of paranoia, but it did not let me down personally, and usually any modifications took place without incidents on my part, and there were dozens, if not hundreds of them (not only did I update my hardware for many years of working with a PC). Another precautionary measure is to try not to take the memory bar for microcircuits, but rather take it for printed circuit board around the edges. It is also not recommended to pass the bar from hand to hand holding the microcircuits.
Rule # 2 - no significant effort is required to remove and install memory modules. It is clear that, if you wish, you can insert anything and anywhere, but after that the device may refuse to work (I have met cases when people somehow managed to "clog" the memory module with the wrong side, or insert an AGP card into the slot PCIe).
Now you can start modifying your iMac. In general, installing memory in most of Apple's thin all-in-ones with Intel processors is the same. There are only minor differences in the design of the slat compartment. 2006 (Early, Mid, Late) iMacs have one bay with two SO-DIMM slots stacked one above the other. All-in-one monoblocks from mid-2007 and later have two bays with four RAM slots. In both cases, the compartments are located on the lower edge of the device, covered with a special plug, which is fixed with two or three screws, respectively. To unscrew them, you need to use a square screwdriver with Philips profile size # 2. By the way, the screws are fixed on the plug and you shouldn't be afraid that they will fall out of it and get lost.
We start modernization
Before proceeding with the RAM upgrade process, you need to prepare workplace... A clean table covered with a soft cloth to prevent scratches on the display will do this. Or, instead of cloth, you can use the porous packing material that the iMac was wrapped in when it was still in the beautiful cardboard box. I worked with him. Place your iMac face down on cloth or packing material. You can take it by the side edges and put it neatly, or by the stand, and the latter option seems to me more convenient and simpler. After that, you need to lift the stand up to gain access to the RAM compartment cover.
By unscrewing the two screws, in the case of older iMac models, we gain access to the RAM modules held in place by two plastic latches.
Even if you only plan to add an additional module without removing what is already installed, the plastic latches still need to be bent to the sides. After that, you can add one more module or install two new ones. It is necessary to insert the strips until they click, they should enter easily (a little effort is applied at the end to click). Note the connector on the memory module - it has two parts. The smaller one should be on the left. After the modules are installed - return the latches to their original position - this is done with a little effort, which is normal. But it is better to see once than read many times, respectively, watch the video:
On iMacs from mid 2007 and later, including the latest aluminum ones, removing memory sticks is slightly different. The photos below (and the first two above) show the 21.5-inch device. Unscrewing three screws and opening the RAM compartment reveals a pair of modules covered with a pair of flexible tabs made of film-like material.
They are easily removed (just pry with a screwdriver or nails, if any, and pull towards you), providing access to the memory strips, but that's not all.
You need to firmly take the tongue with your fingers and pull it towards you. I don’t know how in other copies, but in what I had the good fortune to disassemble, I had to make significant efforts. There were even fears that the tongue would simply come off, but this did not happen. With a light click, the memory bar slid out a couple of millimeters from its slot.
Then it can be easily removed with your fingers. As you can see, this is a regular DDR3 PC8500 module manufactured by Samsung. There is no magic and not even an apple logo.
And here is the empty footprint freed from the burden of RAM:
For greater clarity, watch the video:
In terms of compatibility, for the latest iMac models, any standard 1066 MHz DDR3 (PC3-8500, unbuffered, parity and ECC) modules up to 4 GB (that is, the total RAM can be up to 16 GB) are suitable. It is advisable to take something branded from Samsung, Kingston, Hynix and other well-known manufacturers.
You can read more about compatibility with memory modules in 2007 and 2008 models on the Apple website. Official compatibility information for earlier models can be found at this address.
Happy modernization!
