I saw in the settings that only 5.95 GB of RAM can be used out of 8 GB of RAM, why is that and what can I do so that my laptop can use the 8 GB of RAM

Processor AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx 2.10 GHz

Installed RAM 8.00 GB (5.95 GB usable)

System type 64-bit operating system, x64-based processor

Because the operating system and system-relevant apps also use RAM.

But I currently only have Windows 10 and the settings open

Yes, but also the graphics card, etc. Also consume memory.
