Currently 3 of my 4 ram slots are in use (I split a set of two with a friend). My friend is upgrading, and so I bought back the other stick of RAM from him. I just tried installing it, and no matter what I tried the RAM wouldn't click in to this one slot. I tried the same RAM in other slots, and other RAM sticks in the faulty slot, and it seems that the issue was just the slot. Both clips were undone, and the ram was the right way up, but even with more force than required it wouldn't click in. Is there anything at all I can do about this, or just keep the RAM until I decide to upgrade my motherboard?
