Reinstalling Windows will not fix it. It's usually around 3. Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. This is unusual, but I must disagree with Ken. I suspect this is a rather elderly system. I've done this literally hundreds of times and it always results in an amazing improvement.

Assuming the system is otherwise in good condition, it will perform as well as and likely better than when it was new.

Windows Update is the messiest part of the re-install. Follow my process used hundreds of times and I can virtually guarantee very good results:. Keep in mind that a 32 bit system is not a huge performer and can never be.

Don't expect good performance if trying to use more than about 2 different programs at one time. That includes only 2 tabs in Chrome. First, undo everything you did on the boot tab of msconfig. Msconfig is a diagnostic tool, not a "fix it" tool. Even if a hardware device has its own built-in memory e. That amount is subtracted from the available system memory and is said to be "hardware reserved" and unavailable even though the physical memory is there.

Windows releases. If the memory is remapped, X64 Windows can use this memory. Any X64 Windows or X86 Server release can. The limit that these versions impose is the highest permitted physical RAM address, not the size of the IO space. For example, drivers could map the "lost" memory regions located above 4 GB and expose this memory as a RAM disk.

That is correct. Check whether you have bad memory modules To check whether you are experiencing this issue, turn off the computer, unplug the computer, and 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 determine in what order the memory modules should be inserted into the memory slots. The system may require you to use specific slots when you are not using all the available slots.

For example, the computer has four slots available. But you may have to use slot 1 and slot 3 if you want to use only two memory modules. Check whether memory standoff cards are used If you use a memory standoff card to hold multiple memory modules on the computer, the system may require specific configurations for this scenario. Therefore, the usable memory may be less than expected.

The following sections offer additional information about memory allocation as reported in the Resource Monitor, describe the terminology used, and offer additional information on Memory reporting and memory limitations in Windows 7. The following table shows how the Resource Monitor categorizes the memory currently installed on a Windows 7-based computer.

Memory that does not contain any valuable data and that will be used first when processes, drivers, or the operating system need more memory. Note To view how the installed memory 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 list.

Click the Memory tab, and then view the Physical Memory section at the bottom of the page. The following table defines the Resource Monitors current reported status of the installed memory on a Windows 7-based computer. Amount of memory including standby and free memory that is immediately available for use by processes, drivers, and the operating system.

Amount of memory including standby and modified memory that contains cached data and code for rapid access by processes, drivers, and the operating system. Amount of physical memory that is available to the operating system, device drivers, and processes.

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 memory is available to the operating system. The available memory reported in these earlier versions of Windows does not include hardware reserved memory.

This is a reporting change only. You will see this reporting change in Windows Vista SP1 and later versions of Windows in the following locations:. Additionally, the System Information tool Msinfo 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 system is always less than the physical RAM that is installed.

For example, consider a computer that has an Intel X chipset that supports 8 GB of address space. In this example, PCI configuration requirements reduce the memory that is available to the operating system by an amount that is between approximately MB and approximately 1 GB.

The reduction depends on the configuration. The following table specifies the limits on physical memory for the different versions of Windows 7.

Enabling this technology reduces the overall size of the system virtual address space and therefore system resource maximums. For more information, see What is 4GT. Limits on physical memory for bit platforms also depend on the Physical Address Extension PAE , which allows bit Windows systems to use more than 4 GB of physical memory.

The following table specifies the limits on memory and address space for supported releases of Windows. Unless otherwise noted, the limits in this table apply to all supported releases.

The following table specifies the limits on physical memory for Windows Server Windows Server is available only in X64 editions. The following table specifies the limits on physical memory for Windows Server R2.
