TechPowerUp Memtest64 is a free lightweight, standalone utility that lets you check your system memory for problems at the hardware-level. It has a graphical interface, and can be run from within Windows.
Memory hardware errors can cause major application crashes, blue-screens of death (BSODs), and data corruption. It is caused due to either faulty hardware, or bad memory timings/frequency. Memtest64 lets you test your memory without having to pull out an MS-DOS boot disk. The utility loads your physical memory with test-patterns, and can push other applications into the pagefile to free up memory for testing.
It can also be useful to overclockers who are looking to maximize memory performance by playing with timings and DRAM speeds.

- How can I run memtest86 in a macbook? I've created a Memtest86 bootable usb flashdrive with Windows 8.1. I've tried to start an iMac with it by holding C while it starts and it doesn't work, does nothing. I also tried holding Alt, doesn't work either. According to memtest, creating the flashdrive from windows should boot a mac as well.

Downloads
The latest version is available in the downloads section.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.
RemberRember 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.

‘Closing all apps’ is an option which can be set or disabled in the Rember preferences.
ReplyI’m trying to test DRAM one bank at a time in mid-2010 Mac mini with 2 banks of 4GB Kingston DRAM each.
Download Memtest For Mac Windows 7
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.
Download Memtest For Mac 10.10
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.)
ReplyI 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?
ReplyRember doesn’t shut down existing programs… you do that yerself
ReplyRember 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
ReplyBest Memtest Software
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.

Hope this works well, thanks!
