Fix ‘Windows 10 Won’t Use Full RAM’ – Guide
We as a whole have noticed that when the system consumes a ton of RAM, it influences the PC’s presentation. However, sooner or later we noticed that Windows 11 was not utilizing all the accessible RAM. Memory is used to briefly store the documents the customer is currently dealing with. Assuming there is a problem with the memory, it will really affect the PC’s capacity. Today, we will explain to you why Windows 11 is not using all accessible RAM and how to get Windows 11 to utilize all of your system’s RAM.
Fix ‘Windows 10 will not use full RAM’
Modify the RAM used at startup
This option in Windows is used to reserve the RAM that is used during the boot procedure when the system is turned on. By default, it can permanently and unnecessarily reserve a significantly large amount of RAM for it.
BIOS Settings
There are some settings in the BIOS that can limit Windows from using the full amount of RAM installed. First, if you have a separate dedicated graphics card installed, make sure the internal graphics processing unit (iGPU) is turned off, which is used if you don’t have an external one. If it is On, Windows may be reserving memory for it. To make sure it’s off, restart your computer and enter BIOS/UEFI Setup. You will have to tap a specific key to enter the BIOS and it differs depending on your system model. It can be F1, F2, F12 or the Esc key. You can easily Google your system model to see which key to use to enter BIOS setup.
In BIOS Setup, look for iGPU, Internal Graphics, or Onboard Graphics. The name and location of this setting may again vary depending on your system manufacturer, so you’ll have to look it up. Once you find it, check if it is turned off or off. Also in the BIOS there is a Memory Map Feature which can give Windows full access to the installed RAM. Look for it and make sure it is Enabled or Enabled. In addition to feature mentioned above if you can find the below features, make sure they are in their respective states as mentioned next to them. Save the changes and restart your computer. Check if you can now use all the RAM. If there is still an unusable amount of RAM, move on to the next solution.
Inspect Physical RAMs
In some cases, the reason Windows 10 showed less amount of usable RAM was due to a physical defect. Therefore, we will check the RAMs physically and we will also rule out the possibility that the slots in which the RAMs are installed are defective. Only proceed if you feel comfortable opening your CPU. Disconnect all wires and remove the cover from your computer. Here, you will be able to see the rectangular sticks (RAMs) installed on your motherboard. They will be next to a large heatsink with a fan. There will be 2 or 4 slots where RAMs can be installed.
There will be clips on the sides of the slots. Toggle them and unplug all installed RAMs and make sure the contacts are clean. Also, remove any dust that may be inside the slots. If you have more than 1 stick of RAM installed, it is possible that one is faulty, so remove any of them and start up your computer. Do the same with the other stick of RAM. If the system does not work with any of the RAM installed, that RAM stick is faulty.
Likewise, check the slots in use by inserting a known stick of RAM memory into it and running your computer. If it doesn’t work in any slot, the slot in question is faulty, making the RAM inserted into it unusable by Windows. If all the slots and the RAM stick are working, insert them back in, but in different slots as they were originally before. This is also known to work for some users. Make sure they are properly seated and locked.
update BIOS
In some cases, an outdated version of the BIOS is known to cause this memory bug to appear in Windows 10. The procedure for updating the BIOS varies by system manufacturers and models. Go to your system manufacturer’s website to download and install the latest BIOS version on your system. Before going ahead with the solutions to make your RAM fully usable in Windows 10, make sure that booting the system to a minimum (make sure to empty the PCI slots, e.g. removing a PCI network card) solves the problem. Also, make sure your system supports the RAM you are trying to use, i.e. there is no hardware limit, e.g. Intel 945 chipset motherboard has a hardware limit of 4GB RAM, and more than that cannot be used with it.
Update Windows and your PC drivers to the latest version
Windows, like any operating system, is prone to bugs and the RAM issue in question could also be a result of a bug. Microsoft is trying its best to eliminate Windows bugs and for that it uses the Windows update channel to fill in the latest patches of reported bugs. Before diving into more technical solutions, it will be a good idea to update your system’s Windows to the latest version that may resolve the issue.
Reset your PC’s BIOS to defaults
You may encounter the issue in question if your system’s BIOS is configured incorrectly. In this case, resetting the BIOS to factory defaults may resolve the issue. For illustration, we will discuss the process for a Dell system, you can follow the instructions according to your PC make and model.
