Only half my RAM is usable, when I got my PC I didnt have this problem?

Hi, first of all, I got my PC in 2018 december, and right near the start I ran a test with userbenchmark and these were the results

Update:

UserBenchmarks: Game 70%, Desk 80%, Work 75%

CPU: AMD Ryzen 5 2600 - 80.4%

GPU: AMD RX 580 - 72.4%

SSD: Adata SU800NS38 128GB - 84.1%

HDD: Seagate Barracuda 2TB (2016) - 94.2%

RAM: G.SKILL Ripjaws V DDR4 3200 C16 2x8GB - 79.7%

MBD: Asus ROG STRIX B350-F GAMING

Update 2:

Only now did I do another test and difference seems to be half my RAM

UserBenchmarks: Game 71%, Desk 76%, Work 64%

CPU: AMD Ryzen 5 2600 - 77.9%

GPU: AMD RX 580 - 73.7%

SSD: Adata SU800NS38 128GB - 89.2%

HDD: Seagate Barracuda 2TB (2016) - 97.4%

RAM: G.SKILL Ripjaws V DDR4 3200 C16 2x8GB - 41.7%

MBD: Asus ROG STRIX B350-F GAMING

Update 3:

As you can see my RAM is "performing way below expectations" and when I check my system it says RAM 16GB (7.95 usable). The results are similar in task manager - Memory 16GB (usage 7.9GB)

In use 3.8GB Compressed 46mb

Committed 6.8/9.8GB Cached 3.6GB

Paged pool 467mb Non-paged pool 161mb

Speed 1067mhz

Slots used 2/4

Form factor DIMM

Hardware reserved 8.1GB

Update 4:

Yes I tried msconfig and unchecked the full memory box, it wasnt checked to begin with, restarted my PC and the results are the same. But when I do check the box it does say 16000mb memory, but that doesnt explain why only half is usable now when it was fully usable months ago.

I also checked several forums where people had the "only half my RAM is usable" problem, but none of them had the problem where first it was fully usable and then only half.

    This is the way a modern computer uses it's RAM! Keeping RAM empty is inefficient. It's far more efficient to use it as a read-cache for thing's you've just used and are likely to use again very shortly. So various things are kept in short term storage, if they are needed they can be quickly accessed, but as it's a "read" cache, if they are not needed, they can be over-written with minimal preparation!

      I cant really agree since I just took my 2 RAMs out, switched their places and put them back in. Now the problem seems to be gone, 16GB (15.4 usable). Theres a good reason I wanted 16GB of RAM, if I wanted 8GB I wouldve bought 8GB. But thanks for the answer.

    So what? RAM is never fully used, the RAM has grown far beyond the computers usage speeds.
