Question 6 GB RAM (2x4) but only 1.95 GB usable

[furello]

I have 6 GB RAM (2x4) connected but only 1.95 GB RAM is read, I watched tutorials on Youtube but none of them worked. I run a Windows 10 64bit.

2 x 4gb = 8gb, btw, not 6gb.

Try running memtesst86 on each of your ram sticks, one stick at a time, up to 8 passes. Only error count you want is 0, any higher could be cause of the BSOD. Remove/replace ram sticks with errors.

Win 10 more sensitive to errors with ram so it might have found problems with 1 stick.. now that other total, where is it showing that?

can you search for "System Information" in cortana
choose the desktop app
in file menu, choose export
this lets you save a file with all the info on that screen as a text file.
Upload the file to a file sharing site and share a link here

what shows on the memory tab of task manager/Performance
How much is hardware reserved?

Memory is guaranteed in the form sold. Other combinations you decide to make have no guarantee to be compatible together.

It seems you have an oddball combination. Try listing memory part numbers.
