Windows 10 Home not registering (or using?) all RAM

I am having a problem with Windows 10 and my RAM. If I go into my control panel and look at my system specs, it shows me having 8.00 GB of Installed Memory (RAM). I have 24 GB installed -- two sticks of 4, and two sticks of 8. I used to run 12 GB, two sticks of 4 and two of 2, and this correctly displayed me running at 12GB -- those were leftover sticks from my old computer.

If I go into the Task Manager, and click on the performance tab, the Memory block says I'm currently running 2.1/7.9 GB of RAM. I have one tab of Chrome open, task manager, and Norton idling in the background. It also tells me I'm using only 2 of my 4 slots, and two of my slots add up to 8GB

So here's where it gets complicated for me: In my BIOS (I have a MSI mobo) I can do a thing where it shows my "virtual motherboard" -- I can mouse over the ram slots and it registers them being filled, it correctly registers the brand, and the quantity. I can open the Speccy program, and it shows 24 GB of RAM, and it shows the 4 memory slots being used. I'll attach a screenshot. It says that I have Memory usage of 27%... which is what the Task Manager says, but it says I have 8 GB. Speccy says more about physical and virtual Memory -- The physical and virtual values add up to 24, but I don't understand what this is or what it means for me.

Even furthermore, if I run CPU-Z, it correctly shows me running 24576 Mbytes of DDR3 RAM which is correct.

Why do Task Manager and System Specs report me only having 8 GB of RAM, but analyzing programs and my bios correctly show I have 24? Is Windows not detecting (and therefore not using) that RAM? Is this a W10 glitch?

I've seen other things about disabling automatic paging file managing and things through advanced system properties, but I know nothing about this or what it means for me. Im just worried the 24 GB of RAM I bought isn't all being used.

One final note, I don't seem to ever like, run out of RAM... I'm able to play games while streaming via OBS and having discord open.

Any help is greatly appreciated!

Solution
First check for a BIOS update for the motherboard. Check the motherboard specs to make sure the RAM type you are using can be used, as well as the max RAM amount for the motherboard.
