After banishing 2 2gig ram chips to the depths, which is a cross between the garbage compactor from starwars and a rubbermaid container, the system has ran without a hitch all morning under various stressful loads. I.E Mass Effect 3 and other entertaining testing platforms.
I also ran the SFC - SCANNOW dealy a few times (3 with a restart between each) each of which came back negative with no abnormalities found I think it is a safe bet to declare this one solved. Will give it a day of testing before I mark it as solved and then from there routienely sacrifice some sort of maiden to some sort of demi-god that the last remaining chip remains stable.
Or failing that i'll smash a game boy color open and see what I can cobble together from it's guts. Once again you people were miracle workers, so my deep personal thanks to James7679 and Writhziden which is officially the second hardest name to type correctly without looking at a reference higher up in the thread.
