Regardless of how much memory your computer has, it will only read a maximum of 3. But there are some cases in which the difference between installed and usable RAM is unusually large. This is a tall-tale sign of an underlying problem, and failing to address it could mean significantly lower performance. You can enable the memory remapping feature in the BIOS by booting to the system setup.
See the User's Guide for your computer for instructions on how to boot to system setup on your computer. The name for the memory remapping feature may be different for different hardware vendors. This can be listed as memory remapping, memory extension, or something similar. Be aware that your computer may not support the memory remapping feature. This is the memory that the system is sharing with the video card that is used for texture mapping and rendering.
This memory would not be used by the system, because it is locked by the video card. You can test each setting to see which offers the best results. 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:.

Could the issue be due to mismatched memory or because I am using 3 sticks. Trusted Advisor. Joined May 12, Messages 84, Both of these boxes should remain unchecked.
If "Maximum memory" in yours is checked, how much RAM is listed in it? We don't know anything about your computer and its hardware, so it's unknown at this point why 5. If it has an integrated graphic device, it may be using a large amount for shared memory. If I leave the box checked close the tab and come back it reads 0 when I return to the tab. What Can I do to further show you my specs so that we could resolve the issue? Joined Mar 25, Messages 1. Maybe the issue could be better resolved with a dxdiag report?
Both boxes are suppose to be greyed out and with the numbers that you see in my image. After it's been downloaded and saved, double-click it to run it. Information about your computer will appear. DxDiag file attached here thanks for taking a look. What's the exact serial number and SNID number on yours?
