Hi, recently I bought new ram, it is corsair vengeance pro ddr3 memory. I installed it and everything booted fine, but when I used excel, it would say not enough memory even though I have 16gb which supposedly is plenty for excel. Also, many other programs complain about not enough memory too. I looked in task manager and there was 3.6gb "in use", 12gb available, 4.9/18.3 commited, 6.5gb cached, but those numbers constantly change. My max amount of ram is 32 gb so I could buy another 16, I do video editing, and it is a pain when it constantly says not enough memory.
