Just tried what Willhelm said and no luck whatsoever. Out of all the 360s I've fixed, this one is just refusing to work. Maybe I'm just not putting enough pressure on the other RAM chips, I dunno, I've screwed everything down with two pennies. Nothing. Tried it with three pennies. Nothing. Three pennies stand about 1cm, so I've a feeling if I had another penny I'm going to do some damage.
Something interesting that I noticed which may or may not be helping this error is a slight chip taken out of the second RAM chip, which I will demonstrate with this funny looking MSPaint image.

I'm at an end... any more ideas? =/
