I'm flying.

I have 8 GB of RAM installed on my laptop, but I’m afraid that the system has less than 3.25 GB (about the dispatcher’s resolution it simply says “Reserved by hardware”).

Can I show you why the system doesn’t drain all my RAM and how to properly adjust everything?

Anastasia, Minsk.

Good day!

1. The motherboard or CPU does not support the required memory capacity
2. Each motherboard and CPU have “their own” differences, both according to the system and the type of memory they can deal with.
3. Obviously, there is no way around this exchange. Find out what kind of exchange you can: from the documentation that came with the kit before your entry;

at quiet

characteristics, which you can look at on the manufacturer’s website and in online stores;

at special

utilities, for example, in - tab

"System board/chipset"

. The butt has max. Memory capacity 16 GB, types supported: DDR3-1066, DDR3-1333, DDR3-1600 (SDRAM).

Additions on the topic are floating around... Some computers will supply power, so they cost, for example, 8 GB of RAM, but the system will only have 4 GB, or maybe less..

The power supply is even simpler - it only works on 32-bit systems.

It is likely that devices for configuring a computer take up some of the memory, but not much.

It’s not good for him to complain about this drive.

Another option is to reconvert, which is supported by the system board. However, there is more concern about old technologies. You also need to enable the function before BIOS Memory Remap Feature, (also called:і Memory Hole Remapping H/W Mem Remap

H/W memory hole Remapping

).

After this we install a 64-bit system.

Some of these parameters are already turned on automatically on current boards, so you may not need to switch.

If you actually have less than 4 GB of RAM on a 64-bit system, then the Memory Remap Feature parameter must be enabled at any time.

Not only is the available service possible even less, but the operation of the device also depends, which is especially important when modeling and playing the game process.

It turns out that the BIOS does not load the necessary RAM, so you have to update it.

1. On the right, there is a risk and approach carefully.
2. Instructions for updating can be found on the official website of the system board.
3. More materials:
4. If the installed modules are shown in the BIOS, but Windows is not installed, you may need to check the settings on the motherboard.
5. It says there about connecting specific RAM modules, for example, which mode is better: single-channel or dual-channel.
6. On the official website you can find out about the models that may suit you and the connection option.

If the system does not release RAM, this may result from an incorrectly set life value, as well as through faulty modules.

Moreover, if one of the strips fails, the system may not start at all, so it will need to be woken up. Let's summarize the pouches

Well, we figured out why the computer doesn’t have enough RAM, and also the song.

I’ll write down point by point what needs to be done, as it happens:

Otherwise, not all memory is available to the system:

Also, the BIOS may not show all of its information (usually only half).

Cause

1. Part of the memory is taken by the video card.
2. Edition limit and operating system capacity.
3. Programme interchange.
4. Memory backup by the system.
5. RAM malfunction.
6. Edged from the side of the processor.
7. Update BIOS or need to update.
8. The maximum capacity limit that the motherboard supports.
9. The motherboard does not support one of the memory modules.

Decision

1. Vikoristana of the inserted video card

This problem is characterized by minor problems with the memory of the video adapter.

In this case, we expect small changes in available memory, for example:

Regardless of whether the video card is integrated into the motherboard, it uses the system memory, while it does not consume its resources. To understand which video card is being victorious, you can go to the device manager (command devmgmt.msc ) and open the section:

Video adapters

As a rule, NVIDIA and AMD adapters are discrete (not built-in), and Intel adapters are integrated.

• If we want the installed video card to require less memory, go to BIOS/UEFI and select one of the parameters:
• Share Memory Size
• Onboard VGA Frame Buffer
• Display Cache Window Size
• On-Chip Video Window Size
• Onboard Video Memory Size
• Internal Graphic Mode Select

Integrated Graphics Share Memory

*In different BIOS versions, stinks may have different names.

It is also possible that other parameters can be changed - in this case you will need to read the documentation on the motherboard or use the sound system.

Following this, we change the procedure for reserving memory for the required video system: The butt has max. 2. Programming

The limits can be displayed in the system. To remove it, open the command line and enter the command:

- The “System Configuration” window will open (you can also quickly search for the name of the window in Windows). In the window that has opened, go to the tab and click on Additional parameters

We verify that the checkbox is not checked

Maximum memory

because it doesn’t matter, it’s less important.

Otherwise, just uncheck the box:

b) Windows editions may also be subject to limitations.

For example, Windows 10 Home 64 bit allows you to use 128 GB, and Windows 10 Pro x64 - 512 GB.

Windows 7 Enterprise

Windows 7 Ultimate

If the problem is related to the edition limit, it is necessary to update the system or reinstall it.

4. Adjustment of the basic input and output system

In order for the computer to use all its memory, in some cases you may need to adjust the BIOS/UEFI:

5. Checking the fastening of modules or rearranging memory strips

The memory stick may not be connected to the slot on the motherboard sufficiently, so it will not be used by the computer.

In this case, we are aware of the marriage of a large amount of memory (per module).

Let's try to insert more into the socket.

If the module is installed correctly, it may cause a clicking sound. Sometimes it helps to swap memory modules around. We simply disassemble the computer, assemble the module and change them in place.

In some cases, the slot on the motherboard may be faulty.

If there are a lot of roses, you can try them.

It is necessary to select slots of the same color.

6. Maximum service that the motherboard supports

In case of a memory failure, the system and BIOS do not display all of it (usually only half).

For example, if 16 GB are inserted into the computer (2 sticks of 8 GB each), the maximum capacity is 8.

In this case, you can try pulling out and inserting the memory strips back (you can blow a little bit through the saw).

In addition, the slats can be replaced with bridges.

You can also try cleaning the contacts (use a cleaning cloth first).

Some laptops and all-in-one computers have a cover on the edge that allows you to remove the memory modules, otherwise you will need to open the computer from the outside.

• If this did not help, we will cancel the memory test.
• Finally, if the test also shows part of the memory, you can pull out the offending sticks and insert them one by one - if the computer does not turn on with one of them, the faulty stick will need to be replaced if the computer starts with using planks, perhaps, We are dealing with the Bios problem (click below).

9. Discrete video card

It has already been stated that the installed video card takes part of the memory for its work.

A discrete card, in some cases, can also take away system memory, as it is called “swap memory”.

This occurs when the memory is not exhausted (usually after overclocking or launching powerful games/add-ons).

For the most serious problem, let's try it first:

If the card is disturbed, we restore the old parameters.

Install the video card driver.

If the problem manifests itself, you can try removing the memory modules from the motherboard and cleaning their contacts with a foam pad.

After this we go through the connectors on the motherboard and insert the memory on the spot.

13. Installing drivers for the chipset

Updating or installing the driver may also help with the current problem.

For which motherboard model is indicated, go to the manufacturer’s website, find the page of the specific model and download the driver for the chipset.

We install the backup driver and restart the computer.

The driver can also be installed in automatic mode using the additional DriverHub program.

14. Adjusting timings

If sticks with different timings are installed on the computer, the memory controller automatically adjusts the required parameters, usually focusing on the indicators of the most efficient of them.

It turns out that the controller cannot select the optimal settings. This can lead to the fact that one of the modules does not work correctly and its memory is not corrupted. To adjust timings, go to BIOS/UEFI and select the option for adjusting memory. It is important to know the type of firmware, its version and the driver, which may vary greatly. It is necessary to know the instructions for the previous BIOS/UEFI version to change the timing parameters and set those that correspond to the most advanced memory module. 15. Enable virtualization In some cases, virtualization technology is enabled and can be used to maintain maximum memory capacity.

• To check this option, we try to turn it on. Enablement of virtualization support is required in the BIOS for a section with a name similar to CPU or else CPU Configuration ..
• This section is usually found in the child's Advanced. ..

Depending on the rooted processor, the virtualization support option has different names:

RAM memory is one of the most important, let's say, functional parts on our computer... The amount of memory that is being tested is responsible for the reliability of our computer, and is a sign of the ease of spending an hour at the computer (and not only for those who like to use a computer like a gaming machine)).

This article will look at the nuances of the current problem, if Windows does not waste RAM - what to do with it, as you can get more RAM without costs, or with small financial expenses.

The simplest solution is to install an additional (new) RAM card on the computer's motherboard... but hurry up - there may be a problem with the computer's settings.

But let's take a look at this in order if Windows 7 or Windows 8 does not waste all the RAM.

Text by paragraphs:

Part for: 32 bit versions of Windows 7 or Windows 8

Let us first say that such problems, if the computer does not store RAM memory, are usually caused by either hardware (mechanical) or software problems (adjustments).

Otje: 32 bits Windows versions Vykorist for the whole 4 GB of RAM: if you have a large amount of RAM (more than 4 GB /div. documentation/), to increase the speed of the computer - and at the same time increase the amount of RAM memory, with Whatever the system will be running, you will need to install the 64-bit version.

You can find out the version of Windows that is installed on your computer like this: go to the “System” section on the Windows panel, or click “My Computer” and then click on “Power” with the right mouse button.

In the picture you can see information about “Discharge capacity” and the use of RAM.

The image shows that the system's RAM is 6 GB.

The 64-bit version is installed.

So you understand, in this case, the system of vikorystovuvatimy memory for renewed effort!

And if there was a 32-bit version, it would have been more than 4GB.

Bachita just like that!

If you have a 32-bit version installed, and the RAM is greater than 4, then in order to increase the memory that is used for system work, you will need to change the Windows capacity.

Screenshot for Windows 7: “System power”

As was said above, read the documentation of your system, the very version of Windows installed on your computer.

For example: we are using Windows 7 for free.

The maximum available RAM is 2GB, or 4.

If Windows 7 Home Basic is installed, you will need 8 GB of RAM. Windows 8, one of them remaining versions

, also there may be a limitation.

Windows 8 - maximum amount of available RAM

Windows 7 - maximum amount of available RAM

Note: the RAM memory frame is visible for optimal computer operation.

For example, video cards.

Let's take a look at that situation, if:

computer motherboard may be interchanged

If we, for example, as was said above, bought an additional RAM board, inserted it into the primary slot of the motherboard, but the visible memory is lost to too many values, which means that in the settings of the motherboard There is a sense of exchange.

To ensure that power supply is applied to the memory system, you need to open the BIOS.

How to open the system bios

Quickly use the “restart the computer” button... click... as soon as the system closes and proceeds to a new restoration (indicate the black screen) at this moment, before starting the system restoration itself, you need to press the F2 button or Delete - this is a classic option for most people Iant to enter the BIOS.

Whenever you want to go out, check out the documents on your PC. Once you enter the BIOS, the screen will display parameters, including information about the memory that is being tested. Miracle!

Now write down (or remember the data) the BIOS and compare it with those that can be seen in the “System” data.

As soon as these data are divided, then let’s begin to search for the boundaries of the

Windows system

Or let's look at the possibility of mechanical failures.

It is possible that the type of memory data is not visible in the BIOS: then, it is not trivial, you need to take a closer look at the system data installed on the motherboard on the computer.

1 - you can, for accuracy of reinstallation, clean the contacts of the memory board... if you want, if the board has just arrived (it’s new), then the contacts in the motherboard slot may have oxidized (try changing another slot, just like the original one) no slots - clean the contacts of the exposed slot using a hard cloth.

2 - check to make sure the board fits into the slots correctly!

And I will repeat again: please read the documentation for your motherboard - it is possible that to add an additional memory card you will need to select a specific slot!

Once everyone has checked the mechanical part of their “hatch”, we again update the BIOS and “System” data.

To test the RAM, you can quickly install it Windows system a utility for diagnosing memory, or a third-party program like memtest86.

If you have any questions or have lost your food, please share them in the comments...

This problem can be blamed on whatever Windows.

Let's figure out why all the memory on a computer is not available.

The number of bits/bits and editions of Windows may be affected. Through Windows capacity There may be problems with the assigned RAM. All Windows running 32-bit (x86) cannot support more than 3.2GB of RAM.

If you have, for example, 8GB of RAM installed, Windows 32bit can only use 3.2GB of memory through interchange.

The same goes for the editorial team

operating systems

maybe mothers are oblivious.

For example, Windows 7 home basic can only use up to 4GB of RAM!

• Onboard VGA Frame Buffer
• Uncheck the Maximum Memory option in MSCONFIG
• It’s all simple here: if you wanted to increase the productivity of your PC, you could turn on the “Maximum Memory” setting.
• Onboard Video Memory Size
• It’s easy to turn it on, go to the Server Panel --> Administration --> System Configuration --> Data tab --> Additional parameters --> uncheck the Maximum memory box!
• Video memory on the integrated video card
• Display Cache Window Size
• Share Memory Size
• If we want the installed video card to require less memory, go to BIOS/UEFI and select one of the parameters:
• For those who have an integrated video card, RAM can be backed up under it.
• To enable memory reservation for the integrated video card, you need to go to and enable this setting.
• Look for the following values ​​in Bios:
• On-Chip Video Window Size

Frame Buffer SizeIf you don’t know these values, you’ll have to quickly google and find the setup data for your Bios/UEFI.

Memory reservation for system needs in BIOS / UEFI

The configured BIOS has different amounts of RAM, and Windows often uses them to drain all the RAM.

• Look in BIOS / UEFI for the following settings and change them:
  
• HPET Mode (as such a function) may have a 64-bit value;
  
• Memory Hole may be in memory Disabled;
  
• Memory Remapping;
  
• DRAM Over 4G Remapping;
  
• H/W DRAM over 4GB Remapping;
  
• H/W Memory Hole Remapping;
  
• Hardware Memory Hole;
  
• Memory Hole Remapping;

Memory Remap Feature - all these values ​​are in the Enabled setting.If you don’t know these values, then you’ll have to quickly google and find the setup data for your Bios/UEFI.

Even more often than not However, this value cannot be determined if the Bios is outdated and you would not bother to update it..

How did I earn money by showing one

what is BIOS and how to update it video What other problems could there be with the allocated RAM? motherboard.

But the RAM itself, even though you can access the same inheritances, Windows will not use all the RAM.
