Ubook CWI509 Problem 2: Usable Ram

Having solved my previous problem of the black screen on bootup, I noticed I’m now stuck with another problem. When I first got the tablet, I made sure to give it a quick once over to make sure everything was correct and working. The said installed 8gig of ram showed up and all is well.

Now, windows is showing 8gigs of ram with only 7.82 usable, and this was after resisting the bios back to default. So my question is, has anyone else experienced this and is there a fix for it?
