The only thing I can think of is that the 520's have a problem getting
rid of the extra heat, which might effect the CPU. (The only other effect
would be on the power supply, which can *definitely* handle the
extra memory.

I modified my 520 myself to 2 Meg over 3 years ago, without an add on board.
(There weren't any back then.) I use my ST a *lot* and I have never
had a problem with it...no mechanical or electronic defects at all.

I dunno if that helps or not...but I haven't heard of an epidemic
of blown CPU's due to memory board upgrades before...
