computer can play h.265 and equivalent without troubles, provided video file is no higher than 1080 p.
Computer can play av1 files no higher than 1080 p only if I shut every other application down. If for example I run a browser and an av1 file with either mpv or vlc, system shuts down.
Can I put all that memory to use and avoid overloading the cpu?
Saying RAM can help because you can reencode the video to h.264 or h.265 to make use of hardware decoding is more than a bit of a stretch. You can just reencode it to the normal disk instead. Unless it’s the speed of the local block device that’s the bottleneck here (and there’s no indication that it is, and it would be extremely unlikely), using a ramdisk/tmpfs for any part of that is just pointless.
Yes, but that was in the OP. Maybe normal disk is not feasible for some reason
