To free up RAM on your Mac, firstly, you should find out what app uses so much of your memory. The memory-heavy programs are listed in Activity Monitor, Memory tab. If there is an app you aren’t using at the moment, click it and press the “X” sign to quit it. On Linux, I often use the free command to see the current amount of free and used memory in the system. For example: $ free total used free shared buffers cached Mem: 729 0 388 -/+ buffers/cache: 4284 Swap: 81264428 It does not seem to exist when I enter free in Mac OS X's Terminal.

If your computer crashes after installing a new set of RAMs, there are few possibilities. The first possibility is likely faulty RAM, the second possibility is hardware compatibility. More often than not if it is compatible due to overspec or underspec, your system will not boot up and will make a beeping sound.

Faulty RAMs are pretty rare, almost unlikely if you bought a branded RAM such as Kingston, Samsung, Corsair, Apache and etc, this is because they performed many tests before distributing them to dealers. Based on my experience, here are some possibilities:
- Defective RAM ( Use both Windows Memory Diagnostics and Memtest86 to perform a deep scan, run twice to confirm, if both tests show the RAM is in good condition, then it is most definitely another issue. )
- Outdated Motherboard BIOS ( Update your Motherboard BIOS if it is outdated )
- Outdated drivers and chip-sets ( Update your drivers and chipsets )
- Overheating of RAM ( Use a table fan to test this )
- Faulty RAM slot ( Swap RAM between slots to see if problem continues )
- Incompatibility with your other hardware such as Asus NVidia GTX 970 Graphic Card. ( I’ve upgraded my RAM to 32GB from 16GB for my Dell XPS 8700, unfortunately, the solution to limit the RAM in Windows as shown in Reddit doesn’t work for me.

After much trial and error, swapping graphic cards and RAMs. I’ve discovered that my Asus Strix GTX 970 is unstable when my Dell XPS 8700 has a 32GB Kingston HyperX Fury or 24GB Kingston + Samsung RAM. It runs without problem when my system has both my old (4x4GB Samsung) and new (2x8GB Kingston) 16GB RAM installed, and with no problem when it is 32GB with my older GTX 745 graphic card. This is a very old issue, Nvidia appears to be dragging their feet or this is exclusively an Asus GTX970 problem.

↓ 03 – Rember | Unknown Tests | Mac
Rember is a front-end GUI to the ‘memtest’ command line memory testing program. This application will allow the user to select the number of test loops, as well as the amount of memory to test. There is a ‘Log’ tab that will allow the user to monitor memory testing. The user can toggle a ‘verbose’ switch to limit the amount of output, and can also choose to quit Finder and other applications.
Defective memory can cause computers to malfunction, crash, and behave in a variety of ways which can sometimes baffle end users and computer technicians alike. Apple provides hardware test CDs with most of their products, and there are some third-party utilities for macOS which perform memory testing.
In my experience, these tools have not always been able to quickly and efficiently diagnose memory problems. Rember has been designed to simplify the testing, and diagnosis of these problems.
