- Random Access Memory is a temporary storage medium that your Mac’s CPU uses for fast access to data it’s processing. The CPU can access data contained in RAM much faster than it can data held.
- But running a search for 'RAM' on the Mac App Store will bring up a number of options. Remember to check the reviews to find something reputable. Read next: How to find the best apps on the Mac.
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 apps or software require RAM in order to run and to use them without any lag you will require a sufficient amount of RAM. There are various types of RAMs with different frequency. Higher the frequency of the RAM, the faster its performance. You can simply say the frequency is the speed of the RAM stated in MHz.
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+
https://okpayo.weebly.com/blog/mail-app-doesnt-work-mac. 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.
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.)
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
ReplyRember
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.
ReplyHope this works well, thanks!

Do you need to upgrade your RAM to speed up your computer? Do you want to know how to find your RAM speed and other information on your Mac or PC? Finding out your RAM speed, type and size is important, especially when you need to replace or upgrade your computer’s memory.
What IsRAM?
Random Access Memory (RAM) is the physical hardware within a computer that temporarily stores data. It is one of the most important components of desktop computers, laptops, smartphones, tablets, and gaming consoles. RAM serves as the “brain” of the computer; without it, any system would be so much slower or won’t even run at all.
The computer’s RAM is where your computer stores all the information it thinks you’ll need to access soon, so that your device can read it fast when you need it. It is different from your hard drive, where the data is stored long-term .
Types of RAM
RAM is a catch-all term for all things related to the computer’s memory. However, there are different kinds of RAM designed for different systems. Most of the time, RAM technically refers to Dynamic Random Access Memory (DRAM) or Synchronous Dynamic Random Access Memory (SDRAM ) for modern systems.
The most common type of RAM available today is DDR4, but older systems use DDR, DDR2 or DDR3. Each type denotes a different generation of RAM with different speed, bandwidth and physical design. These types are not interchangeable, so a system that uses a DDR3 or DDR2 can’t be upgraded to DDR4, and vice-versa. This article will show you how to find what type of RAM your system uses and how to find your RAM speed.
How to Detect the Type of RAM in Your Computer
The quickest way to find out the type of RAM you are using in your machine is by looking at your internal system using Windows’ built-in diagnostic tool. You can view and manage all the details of your system using the Control Panel.
Follow these steps to check your RAM type, speed and size on a Windows PC:
- Open Control Panel and go to System and Security.
- Under System, click View amount of RAM and processor speed.
- Here you’ll be able to see all the basic information about your computer.
- To check your RAM type, look at the description beside Processor. You will see your RAM size, model and speed.
Note, however, that this won’t give you information about the type of RAM you are using. You need to dig a little deeper to find out what your RAM type is.
There are two ways to find out what type of RAM is installed on your Windows PC without tearing it apart: via Task Manager and Command Prompt.
To find your RAM type via Task Manager, follow these instructions:
Apple Mac Ram Test
- Click Start and type Task Manager in the search box. Open Task Manager.
- Click on the Performance tab, then Memory.
- You will see the size and type of your RAM at the top right corner of the window.
- In the example above, the RAM size is 2.0 GB and RAM type is DDR3.
To use Command Prompt to determine memory size, type and speed, follow these steps:
- Click Start and type Command Prompt in the search box.
- Click the top result to launch Command Prompt.
- Type in the following command:
wmic MemoryChip get BankLabel, Capacity, MemoryType, Speed, Tag
- You can also use this command to get the full details:
mic MemoryChip get/format:list
BankLabel is where the memory is located, Capacity is the size of the memory, MemoryType is the RAM type , and Tag refers to the unique socket identifier.
The MemoryType is labeled using a number and you can check with the table below to see its corresponding meaning:
MemoryType | Type of Physical Memory |
---|---|
0 | Unknown |
1 | Other |
2 | DRAM |
3 | Synchronous DRAM |
4 | Cache DRAM |
5 | EDO |
6 | EDRAM |
7 | VRAM |
8 | SRAM |
9 | RAM |
10 | ROM |
11 | Flash |
12 | EEPROM |
13 | FEPROM |
14 | EPROM |
15 | CDRAM |
16 | 3DRAM |
17 | SDRAM |
18 | SGRAM |
19 | RDRAM |
20 | DDR |
21 | DDR2 |
22 | DDR2 FB_DIMM |
24 | DDR3 |
25 | FBD2 |
In this example, the MemoryType is labeled as 24, so it is a DDR3 RAM.
