Mac can be conveniently purchased from the Apple store and most of configuration allows you to upgrade the memory so that you don’t need to open the case and take the risk in using an incompatible memory which would cause system lockups.

The only thing is the upgrade from Apple store cost a lot more money if compared to the one that it purchased from a computer store. For example, an additional 2GB of memory cost $50 at Apple Store while it only cost less than $10 if you search in Pricewatch. If you’re willing to take the risk in adding extra memory in your Mac either to save money or perhaps you have a few lying around, it is best to run a memory test to make sure that the RAM is fully compatible and won’t make your Mac unstable.

Here we suggest 3 different methods to easily run a memory test on your Mac OS X including the latest Mountain Lion 10.8.

1. Rember

Rember is actually a GUI for the popular command line memory testing tool called Memtest OS X. Instead of typing commands in terminal, you can run the test by clicking a button. You are able to test a selected amount or all of the memory, specify the number of times the tests should run and also viewing of the log. Rember includes Memtest OS X in the package so there is no need to manually download and install the memtest. Running Rember will show a table displaying the detected memory on your Mac. Select the amount of memory to test, number of loops and click the Test button to start checking the memory. When the tests is finished, Rember will show the test results.

Rember runs in Mac OS X which means that not all of the ram can be tested due to a portion of RAM being reserved for housekeeping.

2. Memtest86+

If your Mac has a SuperDrive, you can burn the pre-compiled bootable ISO image of the Memtest86+ and boot up the Mac with the disc. Just press and hold the C key when starting up Mac to boot from the disc.

The good thing about Memtest86+ is it runs by itself without relying on the operating system, giving you a more accurate memory test result.

3. Apple Hardware Test

This is the recommended way by Apple to test your memory using their diagnostic tool. If you have an installation disc, insert the disc, restart your Mac, press and hold the C key. Select the language for the Apple Hardware Test and click the Test button to start testing. You can also tick the “Perform extended testing” option which would perform a more thorough test that takes considerably more time to complete. On the latest Mac OS X Mountain Lion, the Apple Hardware Test is already pre-installed and it doesn’t come with an installation disc. Simply boot up, press and hold the D key to start the Apple Hardware Test.

You can also see the amount of memory installed on your Mac at the Hardware Profile tab to confirm that the memory is correctly installed and detected. There are some Apple Hardware Test images that can be downloaded for older models. Do note that the Apple Hardware Test images are machine specific meaning that you cannot use the iBook version on a Mac Mini.

Test Ram Mac Online

I’m trying to test DRAM one bank at a time in mid-2010 Mac mini with 2 banks of 4GB Kingston DRAM each.

Rember run overnight on max cycles (255) showed when both banks were full (8GB total), there was a DRAM failure. But run overnight on max cycles (255), Rember is so slow it’s completed less than 30 cycles. I tried this twice.

Is it not possible to check one 4GB stick at a time? (Mid-2010 Mac mini standard RAM is 1GB module in each bank for total 2GB.)

I have several DDR3 DIMMs I want to install, but the memory timing is not printed on them. Is there an app for Macs that can tell you what the timing is on installed DIMMs?

Rember doesn’t shut down existing programs… you do that yerself

Rember is an amazing app! In regards to the comment above:

it closes all windows because to free-up whole RAM memory for tests.
It’s understandable that you must save your work before you open any diagnostic app.

Works great on latest 2019 iMac where Memtest failed and Apple Diagnostic Tool is a JOKE

Rember

I ran this app and it closed all open windows and running apps without asking or warning me. That is bad software. Who knows what data I lost as a result, let alone time in reopening what I can remember was running. memtest does not do this.

How to monitor your Mac’s performance? How to tell that your computer works at its full? How to compare it to other machines with similar specifications? The answer: Mac benchmark tools.

Benchmarking can help you understand the performance of your Mac’s software and hardware, including the disk speed, memory, and graphics card performance. This information is very useful as you can see the weak spots in your system that can be enhanced.

Luckily, there are many apps that can help you measure how various components of your Mac work. And in this article, we’ll look at five tools that can help you test your Mac performance.

You’ll know how they work and what they can measure. Plus, we’ll tell you about a utility that cannot only help you monitor your Mac’s performance but also improve its work and take it to a whole new level. So let’s roll!

1. Blackmagic Disk Speed Test

As you have already understood from its name, the Blackmagic Disk Speed Test measures your hard drive performance, in particular, its reads/writes speeds. It was designed to help video editors to determine if their hard drives can handle various video files.

Blackmagic Disk Speed Test is extremely easy to use. It consists of a single window and a big Speed Test Start button. If you have a single hard drive, simply click the Start button and Blackmagic will test your hard drive and show the results.

If you have multiple hard drives, you need to choose which one you want to test. To do that, go the Blackmagic’s settings by opening the File or Stress menus from its toolbar. Once you’ve chosen the hard drive, you may click Start to run a test.

If you are looking for a good hard drive speed test on Mac, feel free to use Blackmagic Disk Speed Test. It is free to download from the App Store, so take advantage of this tool whenever you need.

MAXON software has been used in different popular movies, including Iron Man 3, Prometheus, and Oblivion.

You can use Cinebench to test:

  • Main processor performance. Cinebench uses all your system’s processing power to test how quickly your processor can render a complex 3D scene that contains more than 2,000 objects, a great number of shadows, sharp reflections, and more. And the higher number you get, the faster your processor.

  • Graphics card performance. This test uses a 3D car scene that shows the car chase. And to test the capabilities of your graphics hardware, Cinebench uses a great variety of different effects and textures. The higher the numbers, the faster your graphics card is.

Cinebench is free to use, so if you need to run a CPU speed test on Mac or measure your graphics card performance, try it out.

4. Novabench

Novabench is a free tool that provides Mac benchmark test for your whole system, including CPU, RAM and graphics performance.
