You probably got your wires on the bottom of u15 in the wrong places.
The instructions are a bit wrong in that the chip counts clockwise from the 
bottom(wirng side).  You probably haven't fried anything.  You should,
however, install the other three 68 ohm resistors in series with
the RAS and CAS lines for the original memory chips.  I  just did  3
units this weekend and all work well.  The symptom you describe can
be duplicated by moving the wires on  u15.  Also, if you don't put
the filter capacitors back in, the exact same symptom will occur, with
 NO damage if not left on for too long.
