[Skunkworks] RAM Upgrade Issue

Hi Skunks, I just upgraded my win 7 PC ram from 4gb (3.37 usable) to 16gb but the usable is still stuck at 3.37. I have gone thru all relevant forums but none has helped yet. I.e -Win memory diagnostic -Advanced boot options (unchecking max memory) Attached snapshots. Anyone ever had simillar issue & managed to resolve? Please share. Bravo 0726506461
