yeah. i checked. mine is a UV405 and the coverage ends at UV342. i guess apple must have completely fixed the problem with the poorly manufactured logic boards by that time... NOT!!!

Guess what?
The problem was that the video chips fell off. It had nothing to do with the RAM. Calm down there partner. Unless your video chip is falling off, you wouldn't be covered anyway.

c'mon people put your heads together. there must be a simple hack for this...

Sure, it's simple. Take the logic board out and using a solder pump, desolder all of the connections and remove the chip. It's just incredibly time consuming and unless you are skilled you will probably destroy your logic board.

How do you know that the problem is a dead DIMM?
It seems highly unlikely.
