Some time ago 4 gigabytes of RAM were enough to work comfortably on a Mac computer. But not today. When it comes to even simple tasks, such as surfing the Internet with a browser with just a few tabs open, the minimum RAM capacity will be too slow for your Mac.
Due to the high cost of any Apple technology, not everyone has the opportunity to buy a new Mac. In this case, the only solution is a RAM update on your Mac. In this article, we will show how to add RAM to your iMac.
Requirements for the iMac memory upgrade
Before buying and installing RAM to your iMac, first, learn about the list of specifications for compatible memory modules on the Apple website. You should clarify the characteristics of your computer, and only then start the Apple memory upgrade:
- Number of memory slots
- Base memory
- Maximum memory
In our case, we will install RAM on iMac 2011. This iMac has 4 slots for a maximum of 8 GB each. So the maximum memory is 32 GB for this model. Our Mac has 2 sticks of 2 GB and 2 free slots. Also, it has 2 free sticks for 8 GB each. So, we have 20 GB RAM in total.
We checked the information on the Apple website for our computer and saw that we need a RAM module with the following specs:
- Standard: PC3-10600
- No buffering or parity
- Number of contacts: 204-pin
- Frequency: 1333MHz
- Memory Type: DDR3 SDRAM
Ideally, you should try to pick up a memory where all the modules have the same volume, and preferably the same manufacturer and series. But, if for any reason, you can’t find the same memory modules – don’t worry, it is not critical.
Preparation before adding memory to iMac
So you’ve checked your iMac memory, bought additional RAM, and now it’s time to prepare your working place for the iMac RAM replacement.
- Make room on the table. Make sure that there are no extra objects, like pens, keys and anything else on the table that can cause damage to the display.
- Place some soft fabric on the table to prevent the screen being scratched as we are going to lay the iMac face down.
- Prepare a simple crosshead screwdriver for opening the RAM location.
- And, finally, don’t be nervous. Everything is really simple.
How to install new RAM on iMac
- Turn off your iMac and unplug absolutely all cables from it.
- Place your iMac face down on the table.
- Find 3 small bolts at the bottom. Unscrew them with the crosshead screwdriver.
- Gently pull the plug. Do not be afraid to lose any screws; they are attached to a special washer.
- Use a screwdriver so as not to damage contact points.
- You will see a small space with two tenons of a material resembling a tape. The tenons are bent simply by swiping with your finger.
- Once you bend the tenons, you will be able to pull out the memory module. Drag it quietly, gradually adding force until you see that the memory is out of the slot. After that, carefully remove the memory manually. The same can be done on the other side.
- Now you can install the new memory to the iMac. The connectors for RAM on the Mac are divided into 2 blocks by two planks. Each tenon is responsible for its unit. To insert a memory, take it in your hand and insert the module into the vacant slot.
- Then gently fold the tenon on the spot.
- Screw the cap in place, put the iMac in its normal position and power it on. The screen may be black for some time until the new memory is initialized.
- Once macOS is booted, enjoy its fast performance.
