Help please, i have installed 4x4gb ram dimms but only 7,9 GB avaible



have you tried swapping the ram? i mean just get 1 or 2 out and see if it works
 


i mean it boots fine, but when i get task manager out, it says 7.9/8 thats cool, if it didnt say 7.9/16 when i put all 4 in ... im getting annoyed... :C
