How do I fix 16gb RAM only 7.95 usable?
In msconfig go to the Boot tab and then click the Advanced Options button on the middle left. A small window will come up called Boot Advanced Options. Make sure that Maximum Memory is unchecked and then click ok to close and reboot if you had to uncheck it.
Why is my 8gb RAM 4GB usable?
If you only see 4GB in your BIOS then Windows actually has nothing to do with your issue. You tested the RAM and it works. Next most likely cause is the RAM slot needs to be cleaned out. You can blow it out with canned air, or use high purity (90%+) isoprobyl alcohol and something that won't leave residue!
