Windows Won't Use Full RAM? Try these Fixes

Windows Troubleshooting
41

Another thing that can be tried, that I di, was up the voltage for your RAM.

My Mobo (MSI 970Gaming, AMD Vishera) was using an auto setting, sitting at 1.3 volts for the RAM. Before upping, I was at 20 installed, 12 usable. From the way I’m understanding it, the 1.3V it was given by the auto setting was enough to power one 8GB and one 4GB stick, hence the twelve before the change, Now I’m running 2.5Volts to RAM and running flawless 20

Hope this helps.

I have installed 64 GB of RAM in two RAM slots.
The RAM is compatible with the motherboard and it is installed properly; But, Windows is showing only 1.88 GB usable out of 64 GB; I have tried all four options; Can somebody help me out?

  1. Are you on a 32-bit Windows or 64?
  2. Go to msconfig -> boot -> advanced options, is there a value specified in maximum memory?

I can’t update my laptop to latest Windows 10 version because not enough memory. I was advised to use 32 GB SD card but it would not accept it. I tried using a 16GB USB but it did not work. I can’t do any of the suggestions I have found because they all say I don’t have enough memory (max is 4GB on my laptop). Can you help please?

Very good tips! :slight_smile:

none worked, option 5: check all your memory. and after that, check your dimms.

64bit. Thanks for the reply. It was the motherboard. I had to return it and purchase a MSI instead. The motherboard had an issue where it would only read half of the install memory. For example, when I installed 16gb, it only recognized 8 and when I installed 32gb, it only recognized 16gb.

Is it 32bit windows 10 or 64bit?

None of this worked for me. Even though it reads me have 16gb of RAM, it says that only 8 of it is usable. I guess I may have to just replace the RAM.
