Memory benchmark — test your PC memory speed
The Advanced Memory Test is part of the PerformanceTest application, and it is designed to test several factors which affect the speed of which data is accessed in PC memory.
You can think of computer memory as a long continuous strip. The strip is composed of millions (sometimes billions) of slots. Each slot has a unique identifying value called its address. On 32 bit Windows platforms the size of each slot is 32 bits or 4 bytes ( 1 byte = 8 bits ). Windows moves data onto and off of this strip as required. For instance, running an executable file from a disk causes Windows to copy the file from the disk to memory and then run the executable from there.
One principle of memory design is known as Spatial Locality. It says that memory addresses which are near each other tend to be referenced close together in time. Memory is designed with this principle in mind and so, we should expect to see a decline in memory access time if we continually request addresses that are far apart from each other.
Users can choose between two types of test — Memory Speed Per Access Step Size and Memory Speed Per Block Size
Memory Speed Per Access Step Size
The first test type, ‘Memory Speed Per Access Step Size’ accesses a
large block, of memory in various sized steps. First, it runs through the
block of memory sequentially, accessing every value. Next it runs through
the same block again, except this time it accesses every second value. On
this occasion, it runs through the block twice in order to access the same
amount of data as the initial step. Next it runs through the same block
again, except this time it accesses every fourth value and so makes four
passes. And so on, until a certain maximum step size is reached.
The size of the block of memory used for this test is one quarter the
amount of system RAM or 512MB, whichever is smaller. The size of the steps
vary from 1 (continuous sequential access), to 1/65536th of the size of the
block of memory.
Memory Speed Per Block Size
When a computer program wants to use a section of memory to store
data, it makes a request to Windows for the amount of memory it requires.
Windows allocates the memory to the program ( unless system resources are
very low ) and returns to the requesting program the address of the first
memory slot in the allocated block. It is possible that some programs may
request very large amounts of memory. The ‘Memory Speed Per Block Size’ test
like the ‘Memory Speed Per Access Step Size’ test, is composed of many
steps. During each step of the test, PerformanceTest requests a block of
memory and runs through the block measuring the access speed. However on
each subsequent step the size of the requested memory is increased, until
finally a block close to the size of the system RAM is requested. In this
way it is possible to observe the different access speeds for the different
sizes of blocks.
Typically it is possible to see a drop in speed when the block no longer
fits in level 1 cache, then again when it no longer fits in level 2 cache
and goes back to main memory. In the case where system resources are low,
swapping to the disk may even be required for very large blocks.
NUMA Settings
Non-uniform memory access (NUMA) is a computer memory design used on motherboards with multiple CPUs, where the memory access time depends on the memory location relative to the processor. Each CPU can have its own low latency local memory, but can still access the remote memory of other CPUs. To make good
use of NUMA, software applications need to be NUMA aware and coded in a way to prefer the use of local memory over remote memory.
The settings in PerformanceTest allow the user to force the RAM test to run on a particular CPU while accessing the RAM connected to another CPU.
RAM type compatibility
The PerformanceTest memory test works will different types of PC RAM, including SDRAM, EDO, RDRAM, DDR, DDR2, DDR3 & DDR4 at all bus speeds.

How to check Windows 7 RAM — 3 test options
PC freezes? Perhaps the problem is with the RAM. The instructions will help you figure out if this is the case.
Why do we need a RAM test
It helps to find faults and fix them. This, in turn, allows you to restore the stable functioning and performance level of your computer.
It is necessary to control the functionality of all assembly components. This reduces the likelihood of failure of components at the most inopportune moment.

Signs of malfunction of RAM
The following moments may indicate that something is wrong with RAM:
- BSOD — screen of death.
This does not always mean that the problem is with the RAM. The symptom can also indicate driver failures, but it’s still worth checking the memory sticks. - Crashes of programs or the system with noticeable loads on RAM. For example, when running resource-intensive software or heavy games.
- Image distortion. Most often, when such a malfunction occurs, users blame the video card for all the sins. But it happens that this is a failure of the operative.
- PC won’t boot and BIOS emits one of these beeps: 1 long or 1 long and 1 short.
Life hacks: How to quickly clear RAM on Windows 10: 7 easy ways
Built-in memory test tools
Windows 7 is equipped with an integrated testing program. It’s called the Windows Memory Diagnostics Tool. The results are presented to the user in the form of a report that is displayed on the screen at the end of the test.
Important! If several memory sticks are installed, it is necessary to test all of them one by one.
To do this, you need to pull out the modules. It is not difficult to do this. It is necessary to turn off the power to the PC and put on an electrostatic bracelet so as not to damage the components. Then find the strips on the motherboard and remove one. The procedure must be repeated until all modules have passed the test.
Modes can be accessed via F1 at the start of the diagnosis. Use the tab key and arrow keys to navigate through the menu. F10 is needed to activate diagnostics, save settings.
In most cases, the usual test that the system performs by itself is sufficient — by default.
Starting the Windows 7 Memory Tester
How to:
- You need to type mdsched in the Start search box, confirm the action.
- Double click on «Memory Checker».
- The software prompts you to restart your computer to start working. Let him do it.
Tip : Before testing modules, you should exit all running programs and close documents.
Memory test results
If the system finds no errors, it will notify the monitor accordingly. Message not received? You can see how the diagnostics went by yourself:
- Log in to the «System» through the «Windows Logs».
- Find MemoryDiagnostics-Results. The result of the test will be displayed at the bottom of the window. It happens that the diagnostic result is shown if you double-click on the name.
If the utility finds problems, or the tests fail at all, some bar is damaged. But you still need to check the rest of the modules.

Important! Only download the software from official websites. Unverified resources often contain viruses.
Memtest86+
Free software.
If you google, you can find the same name, but “Passmark” will stand in front. This is the same thing, but in the second case, you can also find a paid version.
The downloaded ZIP needs to be unpacked. ISO image too. Then it needs to be transferred to the media. You can create a boot disk with this program automatically using the set available on the site.
The test is started with one click, and you can interrupt it at any time using Esc.
Using a bootable flash drive
You can create one using the classic tools built into Windows. Everything is done in a couple of steps:
- Right-click on the ISO file;
- A menu will open where you need to check «Burn Image».
Note : There are also third-party programs for this purpose. For example, Alcohol120% or DAEMON Tools.
After the user has made a boot drive, you must:
- plug in a flash drive,
- in the BIOS specify downloading from the «bootloader»,
- save the settings.
The software will then be downloaded.
AIDA64
One of the most popular programs for checking components, including RAM.
How to test RAM:
- Run software. Its window displays a list of components.
- You need to go to the «Service» tab.
- Select «Test cache and memory».
- In the window that opens, click on «Start Benchmark».
Optionally, you can also perform a general stress test on the computer assembly. It is also launched through the «Service», only you need to select «System stability test».

What to do if the tests found problems In this case, it is worth slowly reducing the timings changed by the user or returning the parameters to the factory settings. After that, you will need to check the modules again.
If the memory has not been overclocked, the following steps can be taken.
