You've got a new device like iMac, but after a couple of years of use you suddenly run out of RAM. For example, the same iMac 5K (2017) has only 8 gigabytes of RAM in the minimum configuration. But do not forget that it has four DIMM slots for a total of 64 gigabytes. In the minimum configuration, you have two 4 GB DDR4 platters, which give 8 GB in total.
Problems when replacing
Once upon a time, 4 gigabytes of RAM was enough, but now it is difficult to comfortably use a computer with this amount of RAM. What about difficult tasks like editing and creating videos, working with graphics and sound?
The problem of lack of memory for running programs is acute. There is only one option left: replace or add another bar to the slot. Unfortunately, Apple has made it almost impossible to replace RAM because itsoldered to the motherboard. Previously, it was enough to take a set of screwdrivers and get access to all the compartments and connectors that are needed for the upgrade.
iMac 5K RAM RAM Requirements
RAM is the memory that stores program data. The program, while in RAM, can run without any expectation from the user, and not open from a slow disk. But this is provided that the bar with RAM has high performance characteristics such as frequency and volume.
This is a specific example of the RAM requirements for the iMac 5K model.
In order for a memory bar to fit, it must meet the following specifications:
- PC4-2400;
- no buffering;
- no parity;
- 204 contacts;
- DDR4 SDRAM, 2400 MHz.
Benefits of substitution
Almost every model of iMac supports replacement sticks, so the RAM for the iMac 27 and other Apple all-in-ones can be upgraded.
- Increasing RAM has a positive effect on application performance.
- Overall speed will increase.
- Multitasking is on the rise.
- Do-it-yourself replacement is cheaper, especially if you use third-party RAM.
Preparation and replacement process
First we need new RAM for iMac. You can buy it in anystore, online store or handmade.
We will look at the iMac 5K as an example:
- Turn off the device.
- Lay screen down so you don't scratch it.
- Press the button above the power connector - this will open the memory module compartment.
- Remove the compartment cover.
- Push the DIMM release levers to open the RAM slots.
- Put everything back.
- Turn on the appliance.
- View PC information under "Memory".
You can go to a service center and ask for a memory module replacement, but the cost of the replacement might put you off.
The iMac 27 5K's RAM changes in the same way as the iMac 5K. Please note that these are replacement methods for 2012-2015 devices.
Replacement on 2007-2009 and 2009-2011 models is different:
- Look at the RAM requirements.
- Repeat iMac 5K example step 1 to 3.
- Use a Phillips screwdriver to remove the memory module access door on the bottom of the notebook.
- Pry out the tab in the memory module compartment. Proceed with caution.
- Insert a new SO-DIMM into an available slot.
- Secure it.
- Put everything back.
2006 models are upgraded as follows:
- Item 1-2 (2009-2011).
- Push the DIMM latches to the open position.
- Attach the SO-DIMM to the bottom slot by positionkey.
- Press the module with two fingers to secure it in the slot. Be careful! If the actions are performed correctly, a soft click will be heard.
- Put everything back.
Depending on the model, the location of the slot may be on the top or bottom.
Features of models when installing new modules
Models manufactured prior to 2017 may beep:
- One beep - no memory installed.
- Three consecutive beeps - data integrity check error.
Conclusion
iMac RAM is easy to change, but you need to follow a certain sequence of actions, take into account the requirements of each individual device, look at its date of manufacture, location of compartments and model.
After replacing the RAM, you can safely use especially voracious programs along with others. Device performance affects all work, especially if you are a freelancer who designs, creates videos or music, does programming.
