You have a new device like iMac, but after a couple of years of use, you suddenly faced with a lack 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 plates of 4 gigabytes of DDR4, which give 8 GB in total.
Replacement Issues
Once there was enough 4 gigabytes of RAM, but now it is difficult to comfortably use a computer with such a RAM capacity. And if it comes to difficult tasks, such as editing and creating videos, working with graphics and sound?
The problem of lack of memory for programs is acute. There remains one option: replace or add another bar to the slot. Unfortunately, Apple made it almost impossible to replace the RAM, as it was soldered into the motherboard. Previously, it was enough to take a set of screwdrivers and gain access to all the compartments and connectors that are needed for the modernization.
iMac 5K RAM: RAM Requirements
RAM is the memory in which program data is stored. The program, while in RAM, can run without any expectations from the user, and not open from a slow disk. But this is provided that the RAM strip has high performance characteristics such as frequency and volume.
This is a specific example of RAM requirements for the iMac 5K.
In order for the memory bar to fit, it must meet the following characteristics:
- PC4-2400;
- no buffering;
- no parity;
- 204 contacts;
- DDR4 SDRAM, 2400 MHz.
Benefit of replacement
Almost any iMac model supports bar replacement, so both the RAM for the iMac 27 and other Apple All-in-One devices can be improved.
- The increase in RAM has a positive effect on application performance.
- The overall speed will increase.
- Multitasking is increasing.
- Self-replacement is cheaper, especially if you take a third-party RAM.
Preparation and replacement process
First, we need a new RAM for the iMac. You can buy it in any store, online store or with hands.
Let's look at the example of the iMac 5K:
- Turn off the device.
- Lay the screen down so as not to scratch it.
- Press the button located above the power connector - this will open the memory module compartment.
- Remove the compartment cover.
- Press the DIMM lock levers to open the RAM slots.
- Put everything back in place.
- Turn on the appliance.
- View PC information in the Memory section.
You can go to a service center and ask for a memory module to be replaced, but the cost of a replacement may alert you.
The iMac 27 5K RAM changes in the same way as the iMac 5K. Remember that these are replacement methods for 2012-2015 devices.
Replacement on models 2007-2009 and 2009-2011 is carried out differently:
- Look at the RAM requirements.
- Repeat step iMac 5K example from point 1 to 3.
- Use a Phillips screwdriver to remove the access door to the memory module at the bottom of the laptop.
- Bend the latch in the memory module compartment. Be careful.
- Insert the new SO-DIMM into the empty slot.
- Pin it up.
- Put everything back in place.
The 2006 model upgrade is carried out as follows:
- Item 1-2 (2009-2011).
- Push the DIMM latches to the open position.
- Attach the SO-DIMM to the bottom slot at the key position.
- Having pressed the module with two fingers, fix it in the slot. Be careful! With the right actions, you will hear a soft click.
- Put everything back in place.
Depending on the model, the location of the slot may be above or below.
Features of models when installing new modules
Models manufactured before 2017 can emit sound signals:
- One signal - memory is not installed.
- Three consecutive signals - error while checking data integrity.
Conclusion
RAM for iMac 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 the date of its production, the location of the compartments and the model.
After replacing RAM, you can safely use especially voracious programs along with others. The performance of the device affects all the work, especially if you are a freelancer who develops designs, creates video or music, and is engaged in programming.
