How To Fix Usable Ram Windows 10 64 Bit

Windows 7 Service Pack ane Windows 7 Habitation Premium Windows seven Professional Windows 7 Ultimate Windows vii Dwelling house Basic Windows seven Starter More than...Less

Symptoms

On a computer that is running Windows 7, the usable memory (RAM) may be less than the installed retentivity.

For example, a 32-scrap version of Windows 7 may written report that there is only 3.5 GB of usable organization retentiveness on a calculator that has 4 GB of memory installed.

Or, a 64-scrap version of Windows 7 may report that at that place is only 7.one GB of usable system retentiveness on a computer that has viii GB of memory installed.

Note The amount of usable memory in the examples are not exact amounts. Usable memory is a calculated corporeality of the total concrete memory minus "hardware reserved" memory.

To view the installed retentivity and the usable memory in Windows 7, follow these steps:

Click Kickoff , right-click Computer, and and so click Backdrop.
View the Installed memory (RAM) value under System. For case, if it displays iv.00 GB (iii.5 GB usable), this means that you have iii.5 GB of usable retentivity out of four GB of installed retentiveness.

Crusade

This is expected behavior on computers that are running Windows 7. The reduction in available system memory depends on the configuration of the following:

The devices that are installed in the computer and the memory that is reserved by those devices
The ability of the motherboard to handle retentivity
The System BIOS version and settings
The version of Windows 7 that is installed (For example, Windows 7 Starter Edition only supports 2 GB of installed retention.)
Other system settings

For case, if you accept a video card that has 256 MB of on-board memory, that retentivity must be mapped within the first 4 GB of accost space. If iv GB of system retention is already installed, office of that accost space must be reserved by the graphics retentivity mapping. Graphics memory mapping overwrites a part of the system retentiveness. These weather condition reduce the total corporeality of system retentivity that is available to the operating arrangement.

For more data nearly how to determine how memory is used on your computer, run across the "Physical Retentiveness Resource allotment in Windows vii" topic in the "More Information" section.

What To Try

There are several boosted situations that could crusade the usable RAM to be less than expected. These issues and possible solutions are listed here:

Check the system configuration settings

This problem may occur because the Maximum memory option is selected incorrectly. To set this, follow these steps:

Click Start , blazon msconfig in the Search programs and files box, then click msconfig in the Programs list.
In the System Configuration window, click Advanced options on the Boot tab.
Click to articulate the Maximum retentiveness cheque box, and and then click OK.
Restart the reckoner.

Update the system BIOS

The problem may occur because the system BIOS is outdated. If you have an older reckoner, the system may be unable to access all the installed RAM. In this example, you take to update the system BIOS to the latest version.

To update the BIOS on your computer, visit the Web site of your computer manufacturer to download the BIOS update. Or, contact your computer manufacturer for assistance.

Check BIOS settings

The trouble may occur because some BIOS settings are wrong.

Enable the memory remapping feature

Bank check the BIOS settings to see whether the memory remapping feature is enabled. Retention remapping gives Windows access to more than memory. Y'all can enable the memory remapping characteristic in the BIOS by booting to the system setup. See the User'due south Guide for your computer for instructions on how to boot to system setup on your computer. The name for the memory remapping feature may exist different for different hardware vendors. This can exist listed equally memory remapping, memory extension, or something similar. Exist aware that your computer may non support the memory remapping feature.
Alter the AGP video aperture size in the BIOS settings

Check the BIOS settings to see how much memory that you have allocated to AGP video aperture. This is the memory that the organisation is sharing with the video bill of fare that is used for texture mapping and rendering. This memory would not be used by the arrangement, because it is locked by the video card. You can adjust the AGP video discontinuity size in the BIOS. Standard settings are "32MB,""64MB,""128MB,"and "Auto." Subsequently you alter this setting in the BIOS, restart your computer, and then check the usable memory. Y'all can test each setting to run into which offers the best results.

Check possible problems with the physical RAM

The problem may occur because there are issues with the concrete RAM installed.

Check whether yous have bad retentivity modules

To check whether yous are experiencing this result, turn off the figurer, unplug the calculator, then swap the order of the memory.
Make sure that the memory arrangement is correct

Refer to the User's Guide of the computer to make up one's mind in what guild the retention modules should exist inserted into the retentivity slots. The system may require you to employ specific slots when you lot are not using all the bachelor slots. For example, the computer has 4 slots bachelor. But you lot may have to utilise slot 1 and slot three if you desire to use only two retention modules.
Cheque whether retention standoff cards are used

If you utilise a retentivity standoff bill of fare to concur multiple memory modules on the computer, the system may require specific configurations for this scenario. Therefore, the usable memory may exist less than expected.

More Information

The following sections offer additional information well-nigh retention allocation as reported in the Resources Monitor, describe the terminology used, and offer additional information on Retentiveness reporting and memory limitations in Windows seven.

Physical retention allotment in Windows vii

The following tabular array shows how the Resources Monitor categorizes the memory currently installed on a Windows vii-based computer.

Retentiveness resource allotment	Description
Hardware Reserved	Memory that is reserved for employ by the BIOS and some drivers for other peripherals
In Use	Memory that is used by process, drivers, or the operating organisation
Modified	Memory whose contents must go to disk before information technology can be used for another purpose
Standby	Retentivity that contains cached information and code that is not actively in utilise
Free	Memory that does not contain any valuable data and that will exist used first when processes, drivers, or the operating system need more retention

Notation To view how the installed retentiveness is allocated in Windows 7, follow these steps:

Click Start , type resource monitor in the Search programs and files box, and then click Resource Monitor in the Programs listing.
Click the Memory tab, and then view the Physical Memory section at the lesser of the page.

Retentiveness condition in Windows 7

The following table defines the Resources Monitors current reported condition of the installed retention on a Windows 7-based reckoner.

Retention allocation	Clarification
Available	Amount of retention (including standby and free memory) that is immediately available for use by processes, drivers, and the operating system
Cached	Amount of memory (including standby and modified memory) that contains cached data and code for rapid access by processes, drivers, and the operating system
Total	Corporeality of physical retentivity that is available to the operating arrangement, device drivers, and processes
Installed	Amount of physical memory installed in the computer

Windows vii retention reporting

Windows 7 reports how much physical memory is currently installed on your computer. Windows NT-based operating systems before Windows Vista Service P1 report how much retentiveness is available to the operating system. The bachelor memory reported in these earlier versions of Windows does non include hardware reserved memory. This is a reporting modify only.

You volition see this reporting change in Windows Vista SP1 and later versions of Windows in the following locations:

The RAM value in Welcome Eye
The Memory value at the bottom of the My Computer windows
The Memory value in the System Properties windows
The Total amount of system memory value of the View and Print Details page of the Performance Data and Tools item in Control Panel

Additionally, the Arrangement Information tool (Msinfo32.exe) displays the post-obit entries on the System Summary folio:

Installed Concrete Memory (RAM)
Total Concrete Memory
Available Physical Memory

The reporting in the following diagnostic tool has non changed:

The Performance tab in Task Manager

When the physical RAM that is installed on a computer equals the address space that is supported by the chipset, the total system memory that is available to the operating arrangement is ever less than the physical RAM that is installed.

For example, consider a computer that has an Intel 975X chipset that supports 8 GB of address space. If you install eight GB of RAM, the system retentivity that is bachelor to the operating system volition be reduced by the PCI configuration requirements. In this example, PCI configuration requirements reduce the memory that is available to the operating system by an corporeality that is between approximately 200 MB and approximately ane GB. The reduction depends on the configuration.

Physical retentivity limits in Windows 7

The following table specifies the limits on physical retention for the different versions of Windows vii.

Version	Limit in 32-bit Windows	Limit in 64-bit Windows
Windows seven Ultimate	four GB	192 GB
Windows 7 Enterprise	4 GB	192 GB
Windows 7 Professional	4 GB	192 GB
Windows 7 Home Premium	4 GB	16 GB
Windows 7 Home Basic	iv GB	8 GB
Windows 7 Starter	2 GB	2 GB
