Imac 27 Memory Slots How Many Digits
Hello all,
I just upgraded the memory on my Mac Mini to 16Gb and I now have two 2Gb memory cards with nothing to do. I'm wondering if I can use them in my wife's iMac. Her iMac currently tells me it has 4Gb for Memory. I don't know if that is two 2Gb cards or one or four! Before I open up her computer to look, can anyone tell me how many memory card slots there are in the iMac? If it already says it has 4Gb, will there be room to add my 4Gb to give her computer 8Gb?
btw, it's a late 2009 iMac 21.5 inch with 3.06 GHz Intel Core 2 Duo running OSX 10.8.5
Thanks in advance for any help.

Apple is charging excessive prices for memory. With the iMac, these prices are about three times higher than the market’s standard storage prices. Ultimately, however, Apple uses standard RAM memory bars that are freely available on the market. So what could be more obvious than simply upgrading the RAM in the iMac Retina yourself?
Fortunately, the memory of the Apple iMac Retina (5K) 27 inch can be upgraded with a few simple steps. That’s why I recommend buying the 27-inch iMac Retina with the smallest amount of memory, and then upgrading the memory myself. With the smaller brother with 21.5 inches, however, the main memory remains firmly soldered – retrofitting is therefore not possible. As a buyer, you have to consider exactly how much memory you will need in the coming years when buying the 21.5 inch model.

Frequently asked questions
Which iMac Retina models have memory upgrade capability?
| Apple model | Size | max. RAM | Upgradeable |
|---|---|---|---|
| iMac Retina 5K (2017) | 27 Zoll | 64 GB | |
| iMac Retina 5K (End 2015) | 27 Zoll | 64 GB | |
| iMac Retina 5K (Mid 2015) | 27 Zoll | 32 GB | |
| iMac Retina 5K (End 2014) | 27 Zoll | 32 GB |
Will Apple’s warranty be maintained?
The memory of the iMac Retina 27″ can be upgraded by yourself and the Apple manufacturer’s warranty is maintained. Apple even offers its own illustrated tutorial online.
Can different memory sizes be mixed?
Memory modules with 4GB, 8GB and 16GB can be used in each slot and from the end of 2015 also 16GB. As a result, different sizes can be mixed in pairs (e. g. 2x 4GB + 2x 8GB) in principle. Then, however, the dual channel is dropped. However, the impact on iMac performance is not noticeable during operation. When upgrading, it is important that the memory specifications are exactly the same.
Possible memory combinations with the iMac Retina 27″
Hinweis:The memory banks 1 + 3 and 2 + 4 belong together and are color-coded accordingly in the table. Same memory modules should be used in related memory banks. Examples of possible configurations:

Preparation
The iMac Retina must be shut down before installation. We also remove the power plug and other cables before starting the upgrade. Then place the iMac Retina carefully, with the display facing down, on a soft surface (e. g. towel) on the table. This means that the display is not scratched and we can easily reach the memory cover for installing the new memory modules. Special tools are not required for installation.

Installation instructions
Imac 2019 Memory Slots
| Step 1:Directly above the power cable socket is the release button for the upper memory cover (see photo marking). As this is very narrow, it can be pressed in with a flat plastic object (e. g. SD memory card or bank card). |
| Step 2:After the release button has been pressed, the memory cover opens and can be removed. On the inside of the cover there is a drawing showing how to swing out the slot block. |
| Step 3:Now unlock the slot block first with the two levers (left and right). To do this, press the levers slightly outwards and swing out the slot block. |
| Step 4:Now the RAM modules can be easily exchanged. When inserting the new memory ledgers, pay attention to the indentation between the contacts. The memory banks 1 + 3 and 2 + 4 belong together. For this reason, the same memory modules should be used in related memory banks. |
| Step 5:After the new memory ledgers have been inserted, the slot block is swung back into the housing and the cover is clipped in. |
