“Does it have 2 x (4gb) memory sticks or 1 x (8gb) ram attached to the board? I want to upgrade the memory. I found one person saying that both slots were full with two 4gb cards, and another person said only 1 slot was used with an 8gb card leaving an open slot. I hope it has just one 8gb card, because I'm just buying one additional 8gb stick and I'd have 16 total gb. If it has 2 x 4gb sticks, I'd have to throw one of the 4gb sticks away and only end up with 12 total gb (4gb + 8gb)”
