First of all you have to check if the RAM sticks have the right specs for
the QS: PC-133 3.3v, unbuffered, 8-byte, non-parity 168-pin SDRAM
To check, goto:
<http://www.chipmunk.nl/DRAM/ChipManufacturers.htm>
(yes, again Chipmunk.nl !) and follow the instructions.

Now: Carefully clean the 168 pins of the stick using a pencil-eraser.
Mount and unmount the stick (one from a working slot!!) a few times and see
what happens. Let us know.

You are welcome.
For me the most effective way, in combination with the link to apple-history
and Mactracker (free at <http://www.mactracker.ca>), to find out what Mac I
have on hands!
