I have installed 6GB DDR3 1600hz Kingston ram in my Windows 10 Pro 64-bit computer. But the system does not recognize all my RAM after installed version 1803. It just only says that 4GB RAM. I run the CPU-Z tool and it reports the device supports up to 16GB. I could not run apps and games with multitask smoothly. How can I resolve it?
If the Windows 10 only use a part of the total amount of RAM, try any of the tips to troubleshoot that.
By default the RAM is reserved to use for booting procedure. You could modify large amount of RAM.
* Press Win + R from your keyboard, type msconfig in Run dialog box, and click OK button.
* In System Configuration window, click on Boot tab, highlight your current operating system, and click on Advanced Options button.
* Uncheck the “Maximum memory” box. click OK > Restart button.
The usual solution
* Making a boot can get it working without issue. However, sometimes it requires powering down fully and doing a cold boot.
Setup BIOS Settings
* Restart your PC and boot into its BIOS/UEFI setup screen by pressing F1, F2, F12 or the Esc key.
* Locate the iGPU, Internal Graphics or Onboard Graphics option, and disable them completely.
* Then search for Memory Map Feature, and turn it on. Finally save your changes and restart to normal mode.
The culprit may be the motherboard or the physical RAMs.
* If you have installed more than 1 stick of RAM on your machine, remove any one, check the slots and power on the PC. If it fails to load system, that stick of RAM causes the problem and you have to buy new hardware.
