hardware reserved might be related to a bios setting for an AMD APU. if that was the case your computer would only show 6gb total even though you know you have 8 installed (given you set gpu allocation to the 2gb max)

could be a ramdisk. I'm sure you would know if you had one of these setup.

end of the day as long as its not impacting your performance it dosent matter.

load up chrome and do 20 tabs. if it dosent lag out and crash then your good anyway

I had the exact same problem with 2x4gb RAM. I couldn't find a solution and ended up replacing the RAM (for 2x8gb). It worked just fine after that.

Have you tried inserting each individual RAM stick by itself to check if the problem is with the RAM?

Well yeah both ram sticks work fine. Everything seems to be fine ram slots ar working, ram is working everything but still from 8gb only 3.96 usable and 4gb are in hardware reserved. is there any fix for it. i dont really want to but new 8gb stick bcs i need the money for somethign else.
 


But have you tried to power down and reseat the RAM? Does it have 4 slots? Move them to the other two slots.
