Matey, don't replace the 2 1Gb sticks for a single 2Gb stick... That board takes dual channel memory, so any RAM you put in, you should buy in pairs. Either Remove the two 1Gb sticks and stay with 4Gb :/ Buy another matched pair of the RAM you already have - this would probably work Sell the other 2 sticks of RAM and buy 4…
Can you circle the issue, or explain it better? I'm not sure what we're looking for, and nothing sticks out, aside from the noisy liquids in the flasks.
HP sticking through the LP is fine (actually it's normal, the HP and LP should match as close as possible so they should be sticking through each other everywhere), HP sticking through the cage is bad. The program will only bake whats in the cage, there will always be errors anywhere the HP sticks through, the whole point…
3 sticks of 4gb.. However with 3 sticks it would shift into single channel mode, since it's a dual channel board. Your better off doing 2 or 4 sticks of ram at a different capacity. 2x4gb + 2x2gb/ 3x4gb + 1x2gb/ 4x 4gb/ 4x2gb
