RAM test. Programs for checking RAM Online RAM test windows 7

The cause of many critical errors (BSOD) and subsequent reboots, freezes, and malfunctions is faulty RAM.

The easiest way to identify a faulty module is to use the standard utility from Windows 7 - "" (Windows Memory Diagnostic Tool). This verification tool appeared back in Windows Vista, but many never used it, and in earlier OSes it was not included at all with Windows, although it could be downloaded separately. When using the "Windows Memory Checker" you do not have to create additional boot disks to burn the utility, but you only need to restart your computer or boot from an existing Windows 7 installation disk.

Since the time when Windows Memory Diagnostic lived a life separate from Windows, a lot of time has passed, and the utility has undergone some changes, the set of tests used has expanded, constant monitoring has appeared, the interface has been simplified as much as possible for use by the end user.

As a rule, the system can automatically detect obvious problems with the computer's memory and prompt you to run the diagnostic tool, but this is only if the OS is installed and bootable.

It is necessary to identify and replace faulty memory in a timely manner, until "blue screens" and other symptoms become constant companions of your work.

If changes were made to the BIOS (overclocking, voltage changes, etc., etc.), you need to return everything to its original state and check the operation in this mode.

Running from a running OS

Follow: Start ---> Control Panel ---> Administration ---> Windows Memory Checker.

Or: Start---> in the search bar, type " mdsched" without quotes and click " Enter".

Or: Start---> in the search bar, type " memory" without quotes and select this item:

The following window will appear:

Start at computer boot

When loading, press the key F8 on the keyboard, the "More Boot Options" selection menu will appear:

Click " Esc" to go to the Windows Boot Manager menu, then " Tab", then " Enter".

Starting from a Windows 7 installation disc or from a system recovery disc

You must press any key while this prompt is on the screen.

If you are using installation disk, in the first window press " Further":

Choose " System Restore":

The next 3 steps are identical.

Select the first option and click again Further":

Press " Windows Memory Diagnostics":

We choose the first option:

Working with the utility

After starting, the test will immediately begin (with standard parameters):

To change the settings - click " F1":

You can select different "Test Sets":

"Basic set" includes only 3 tests, use it for a quick check:

The "regular set" is used to perform standard tests:

To select the next parameter, press the " Tab".

Enabling/disabling the cache for various tests serves to identify different types of errors.

When the cache is disabled, the utility accesses the RAM directly, this provides the most accurate testing of the modules themselves.

Set the number of passes, the more passes, the greater the probability of detecting defects.

We start testing with the given parameters by pressing the " F10".

When the test is completed, the computer will automatically restart.

Information about testing and found / not found problems is always on the screen, in addition, in case of errors, information about them will be shown after Windows boots (if the test was launched from the OS).

Scheduled launch

It is very convenient to schedule the launch of the utility on a schedule, for example, once a week. To do this, set the parameters by analogy with the screenshots below:

Start the task scheduler Start ---> All programs ---> Standard ---> Service ---> Task Scheduler), press " Create a task":

Go to the "Triggers" tab, click " Create":

Go to the "Actions" tab, click " Create", in the "Program or script" field, write:

In the "Add Arguments" field, type:

/bootsequence (memdiag) /addlast

Go to the "Parameters" tab:

Now once a week, the utility will be automatically added to the Windows bootloader and run on the next reboot after the addition. Reboot, however, can also be scheduled.

Eliminate possible problems associated with the operation of the utility

If you encounter the fact that the utility starts every time you start Windows 7 (or the check "loops" and does not stop in the usual way), fixing the situation is very simple. It is necessary to manually remove the utility launch entry from the Windows bootloader.

Conclusion

In this article, I told you how to check the RAM with a standard utility from Windows 7 - " Windows Memory Checker".

If a failed memory module is found, you must replace it with a new one; do not forget to check the new module immediately, because. often low-quality memory "slats" get on sale.

Hello, dear readers, Denis Trishkin is in touch.
The computer consists of several key boards and elements. One of them is working memory. In case of problems with the PC, this element is not the source in most cases. However, there are still times when you first need to check the RAM in Windows 7, and only then try other tools.

Random access memory (RAM or random access memory) is a part of a computer system that stores executable code and intermediate data that is currently being processed by the processor. She is energy dependent. This element is considered one of the key ones, and therefore the computer cannot work without it.

If there are problems with this component, this usually manifests itself in two processes: a constant reboot of Windows or the appearance of a blue screen of death.

What to do?( )

First you need to find out if the instabilities that appear are related to this particular component or to others. This will help you understand what to do next.

In the event of a RAM failure, there are only two options:

1 Component burnt out. In this option, when turned on, all coolers start to rotate, but nothing else happens.

2 The element works partially. Failures could occur in one or more chips. Here the situation is not so obvious. The operating system can run for a period of time loading RAM. In this case, during the launch of a resource-intensive program, Windows will reboot, freeze or show the screen of death.

In the first case, everything is clear - you need to replace the component. In the second - first you need to fully test the memory for errors. This can be done using a standard system application or a special program.

Embedded Solution in Windows( )

If you manage to boot the OS, then this element has not burned down. To find out the specific causes of failures, you need to run the appropriate health check program.

For this:

1 Go to " Start" and type "" in the search bar. We launch.

2 A new window appears. It must indicate exactly when you want to check the device. You can do this immediately or already during the next power-up.

3 Before choosing the first option, you need to save all open documents and close the programs. Then "".

4 The system will restart and diagnostics will begin.

5 If a problem is identified, a corresponding record will appear on the monitor.

6 To select additional scan options, click " F1". Most often, if errors are present, they will be found using the standard settings.

increase

In addition, you can run the diagnostic wizard the next time you start Windows. To do this, in the OS boot manager, click " Tab» and select « Diagnostics

increase

What to do if errors are found?( )

You need to understand right away that it will not work to correct the error and return everything as it was before. If defective components are found, contact the place of purchase. Well, if the device is under warranty. Otherwise, the chance of replacing a damaged module is minimal.

Interesting to know! In Windows, in the event that a RAM problem is identified, it is recommended that you contact the component manufacturer itself directly in order to obtain all the necessary information to resolve the error.

Extra options( )

If there is a suspicion that there are some problems with the RAM memory, it is recommended to run diagnostics with standard parameters. But at the same time, you can fine-tune the process. As already mentioned, for this you need to click " F1».

In the window that appears, set:

To proceed to the next parameter setting, press " Tab". To return - Esc". After specifying everything that is needed, click " F10 and testing will begin.

Memtest tester( )

This product is considered the best for testing RAM. It is compatible with the latest versions of Windows starting from Vista. This application runs eight different tests in turn to detect problems with RAM. Each of them is designed to test its own area, including the frequency of operation. For the correct functioning of the program, you need to make a bootable disk or USB flash drive.

To do this, we find a program that is already offered in the * .iso image. After that, it must be written to a disk or portable storage device - by running the downloaded imageUSB program file.

increase

Then we insert the disk or USB flash drive into the computer and reboot. We need to set the BIOS to boot from a USB flash drive or use the boot menu - for a more detailed explanation of how to do this, use. After that, we save, reboot and throws us into the testing window.

increase

Important! Diagnostics should be carried out only in this way. If you decide to try to check the RAM from under Windows, this may lead to a premature reboot. As a result, you will not achieve the desired results.

If errors are found, red lines appear on the monitor, which contain all the necessary information.

increase

It is also necessary to clarify that in the case of using several memory sticks, you need to check them one by one. Otherwise, it is simply impossible to determine which module has failed.

It must be remembered that although the RAM is not considered the "heart" of the computer, it is nevertheless an important node, which is also supplied with voltage for operation. Therefore, any overvoltage in the system negatively affects, as well as on other elements.

In the case of constant use of the computer under heavy loads, many experts recommend installing an additional number of coolers on the case - as many as fit on the rear panel. This will help to cool not only the memory bars, but also the rest of the elements.

In addition, on the technology market today you can find additional components for cooling RAM. They are:

It should be noted that in addition to problems associated with production or operation, RAM can also stop working due to one more common ailment - dust. In this case, the computer sometimes does not start at all and even gives out sounds, the designations of which are simply impossible to find in any user manual.

Computer builders often install RAM boards in the first slots that are closest to the processor when building a new machine. If you notice this in yourself, it is advisable to move them away. To enable dual-channel mode, you can install them in slots of the same color. This should speed things up.

Dust is actually the enemy of all electronics. You can use a brush or a soft brush to clean it. It is necessary to clean the recesses in the connectors and the contacts themselves on the board well. You can also use a soft eraser for this procedure. After its impact on metal parts, you can immediately notice that they will become lighter.

Virus damage( )

Separately, it should be said that there are some viruses, the action of which can lead to the failure of RAM-memory. Fortunately for many users, this program is not common on the World Wide Web, and it is extremely rare to find it. In addition, antiviruses try to look for such software not only on individual devices, but also on the Internet, cleaning it out. This only proves once again that it is better to have a security program on your PC.

For any of the users, perhaps, it will not be a discovery of the century that most of the error messages that appear when working with Windows 7 arise from all sorts of problems with the computer's RAM. At the same time, it is not so difficult to detect them, as it seems at first glance, and even without resorting to the help of third-party programs. The point, in fact, is that Windows 7 itself already has a built-in utility for checking RAM, which is not much inferior to similar programs in terms of efficiency. Do you want to check it out? Then get to work!

Option #1: Microsoft System Method

It is worth noting that testing RAM using the tools of Windows 7 itself can be performed in different ways, depending on whether the computer is in working condition or not. In particular, for a normal check of the health of the RAM on a PC, you can use this method:

In addition, it is also possible to check the operation of the RAM when Windows 7 starts. In this case, when starting the computer, you will first need to press F8 in order to get to the menu of additional boot options, and then select Esc on the keyboard one by one (to access the Windows boot manager), Tab ( to select a memory test tool) and finally Enter (to start diagnostics):

At the same time, you can also arrange a RAM test using the Windows 7 distribution disk. In this case, after running it on a computer in Windows installation mode, we only need to open the system recovery options and select the memory diagnostic program among them. The whole process looks like this:

In any case, regardless of the method chosen, after starting the system diagnostics of the RAM, a blue window will appear in which the entire test progress will be displayed:

True, you need to consider that by default in Windows 7, the usual set of several standard RAM tests is selected. It provides, of course, a check that is quite quick in time, but of average efficiency:

In this case, for a more thorough analysis of the RAM after running the utility, it is preferable to reconfigure the test scheme by choosing a wide set instead of the usual set. How to do it? Just press F1 first and then Tab to select the appropriate option and F10 to save the setting. Similarly, disable cache validation and increase the number of passes to at least 20 in order to increase the efficiency of passing the test.

One way or another, after the analysis of the RAM is completed, the testing tool built into Windows will notify you of all the errors found in the report or in the system message after restarting the PC (depending on the selected diagnostic method).

Option #2: RAM Tester Programs

At the same time, RAM on a computer with Windows 7 can also be checked for errors using special RAM tester programs. They are presented today quite widely, but free software tools such as SuperRam, MemTest86 and SiSoftware Sandra deserve special attention among all of them.

The easiest to use among them is undoubtedly the Russian-language utility SuperRam. At the same time, in terms of the effectiveness of RAM tests, it is not much different from the well-known software “monster” MemTest86. This utility, in particular, allows you not only to test the RAM on your computer in different modes, but also automatically increases the productivity of its use. In addition, the program is compatible with absolutely all RAM modules and Windows versions, which turns it into a truly indispensable tester for a PC.

Meanwhile, at the first sign of the impending demise of the RAM, appearing along with the blue screen of death, the MemTest86 program can bring the computer back to life. Its peculiarity is that, unlike many other similar utilities, it is launched in a “clean” form using its own bootloader, which provides it with a more thorough test of operating memory for bugs.

True, MemTest86 also has two small drawbacks. Firstly, in order to check the RAM with it, you will first have to work on writing a resuscitation flash drive with an iso image of the utility; and, secondly, the process of analysis using this testing software usually takes a lot of time - from 1 hour or more, as practice shows.

As for SiSoftware Sandra, this program can hardly be called a full-fledged RAM tester, given that it has both a general Windows stability test and separate modules for analyzing the state of the motherboard, CPU, video card and other equipment connected to the PC. Meanwhile, its performance indicators are quite good, which, however, distinguishes it from a dozen other analogue programs.

Software for testing computer RAM ( RAM) are programs that perform detailed tests of a computer's memory.

The memory installed in your computer is very sensitive. It is recommended to check the new, just purchased, RAM for errors. And, of course, testing is essential if you suspect you might have a problem with your existing RAM.

For example, if your computer does not boot or restarts unexpectedly on its own, then this may indicate certain memory problems. It is also useful to check the memory in these cases:

programs used on the computer periodically give an error and close;
during the restart of the computer, it emits various beeps;
is displayed.

All memory test programs mentioned in the article run outside the operating system, so each of them will work regardless of the operating system you use: Windows (10, 8, 7, Vista, Windows XP, etc.), Linux or any other. Also, remember that the term "memory" in this context means random access memory (RAM).

Important: if the test results found problems in the memory, it is necessary to replace it, because. it is beyond repair.

- absolutely free, does not require installation and very easy to use program for testing RAM. If you don't have time to try and compare different programs, use Memtest86 - this is the best program to test the RAM on your computer.

Simply download the ISO image from the MemTest86 website and burn it to disc or . After that, simply boot your computer from the disc or USB stick that contains the program.

Despite the fact that this program is distributed free of charge, it also has a Pro version, however, if you are not a professional computer hardware specialist, then the free version with basic support will be enough.

To run MemTest86, you do not need to boot the operating system, it is only necessary to write to a bootable device (disk or USB flash drive). This can be done using any version of Windows, as well as Mac or Linux.

is a free memory testing program from Microsoft. It is very similar to other RAM testing programs and runs a series of tests to identify problems.

Just download the installation file and create an ISO image to burn to a disc or flash drive.

After booting from a disk or flash drive, Windows Memory Diagnostic will automatically start testing the memory and will repeat the test until you stop it.

If the first group of tests doesn't find any errors, your device most likely has good random access memory (RAM).

Important: Windows Memory Diagnostic does not require Windows (or any other operating system) to be installed, you only need the system to burn an ISO image to a disk or USB device.

is a modified version of the Memtest86 program that was listed first in this article. Memtest86+, like the original program, is completely free.

We recommend that you test your memory with Memtest86+ if you have any problems using Memtest86 or if it reports errors and you want to check the test results in another program (double check).

Memtest86+ is available in ISO format for burning to disk or flash drive.

It may seem a little strange that Memtest86+ is only listed in 3rd place in this list, however, since the program is very similar to Memtest86, it would be better to try the original version of Memtest86, and then Windows Memory Diagnostic, which works differently, as a result which you get a fairly balanced algorithm for checking RAM.

As with Memtest86, to create a bootable disk or flash drive, you will need a Windows, Mac or Linux operating system, which can be run on a different computer than the one that needs to be tested.

Another RAM testing program that works very similar to those already listed earlier.

One of the major disadvantages of DocMemory is the need to create a boot floppy. Most computers today no longer have disk drives. Therefore, the best memory testing programs (see above) use boot disks or USB sticks.

We recommend that you use DocMemory Memory Diagnostic only if the test programs listed above do not work or if you want to find confirmation that something is wrong with your memory (after checking with other programs).

On the other hand, if your device can't use discs or USB sticks, then DocMemory might be exactly what you're looking for.

The need to check the RAM (RAM) is dictated by the frequent occurrence of the following situations in Windows 7:

The appearance of the "blue screen of death" (BSOD).
Computer freeze.
Unstable or incorrect operation of the computer.
Critical errors when running applications.

In all such cases, RAM is the most likely culprit and needs to be checked. There are several ways to test RAM in Windows 7.

Windows 7 built-in test

Unlike previous versions of the OS, which required the use of third-party applications to analyze the health of this computer node, the seven provides a built-in tool for this. It can be launched in two ways:

From the command line.
From the control panel.

To run this tool from the command line, you need to click "Start", type mdsched in the search bar, press the Enter key. The following window will appear:

This window shows two options for performing the built-in RAM test:

Delayed start of the test the next time you turn on the computer and start Windows.

Which option to choose depends on the user's intentions. Needless to say, when choosing the first option, you need to save your work and close running applications, which is what the message in the window reminds you of.

To run this tool from the control panel, select "Administrative Tools" in it, and in the list that appears on the right side of the window, select "Windows Memory Checker":

Further actions of the user and the computer are the same as when starting the test from the command line.

Built-in memory checker settings

It is recommended that you run this tool with the default settings first. If no problems with RAM were found, then a more detailed analysis can be carried out. To do this, run the built-in test again and press the F1 key while it is running, after which a settings menu is displayed, which can be navigated with the arrow keys and Tab. This tool provides three analysis modes that differ in the set of tests and the completeness and time of passage:

Basic (Basic) - duration of several minutes.
Standard (Standard) - takes about an hour.
Extended - up to several hours.

At default settings, all tests are run in two passes. This value can be changed from 0 to 99. If set to 0, then testing will be performed indefinitely until it is stopped by the user, which can be done by pressing the Esc key.

The successful completion of the RAM test is indicated by the appearance of a window like this:

Boot Memory Check

This is another option for running a built-in test, which is used when, due to problems with RAM, it is not even possible to boot Windows. To launch it after turning on the power of the computer, use the F8 key to achieve the appearance of a menu with additional boot options, then press the Esc, Tab and Enter keys in sequence:

The built-in diagnostic tool will start:

Upon completion of the check, Windows 7 will automatically restart and its normal operation will begin.

Checking RAM using the Memtest86 utility

Many third-party utilities have been developed for RAM tests, but Memtest86 is deservedly considered the “king” among them. It differs from many similar programs in that it has its own bootloader and runs from bootable media (for example, from a USB flash drive or CD). This allows it to more thoroughly diagnose the performance of RAM. Unfortunately, this utility has two drawbacks:

The need to obtain bootable media from the distribution iso file. It is hardly necessary to attribute this to shortcomings - that is why the program does not require any OS, and does not depend on it.
Quite a long test execution time (more than 1 hour).

When should it be used:

Of course, the first and most frequent case is that the OS does not boot up, or a BSOD appears.
When the PC is unstable.
Diagnostics of purchased and non-working RAM modules.
For fine-tuning timings when overclocking system components.

What to do if tests reveal problems

If errors were detected during testing in any way, or the tests could not even complete, then this is a clear sign that one or more RAM sticks are faulty. What to do in such cases:

Don't be in a rush to get new boards. First, remove all the strips from the slots and reinsert. Just remember to turn off the computer before doing this and discharge static electricity by touching the computer case.
If a lot of effort is required when removing and installing the slats, then either you forgot about the latches of the slats, or you insert them incorrectly.
Gently wipe the contacts of the bars with an eraser to remove the plaque formed as a result of contact with air and subsequent oxidation.
Install the brackets in the motherboard slots, turn on the computer and repeat the test. It is possible that the test will end successfully.
