imac 266 Mhz - memory problem - shows double the memory

[gagix]

hi everyone
i just got a old iMac 266 Mhz..one of the 5 color
versions..mine is purple...
well. it had 32 Mb ram in it, so i thot to upgrade and
i purchased 128 Mb ram.
I installed it in the top slot and when i turned on
the mac booting OS9 it showed that i had 256 Mb ram
chip in the top slot instead of 128 Mb.
I switched the slots and it showed the same.
I tried installing Mac OSX but it would freeze after
booting up during the first install screen.
When i removed the 128 Mb ram chip, things worked fine
and Mac os x installed fine.

So my question is, do i have a bum 128 Mb chip ? or is
there any other setting i am overlooking..
I checked that the 128Mb ram is meant for the top slot
of the iMac (since this iMac has diff physical memory
chip sizes for top/bottom slots).
If anyone can figure out what i just explained and can
point me to some info i would be extremely grateful !!
Thanks a lot !

What kind of ram is it? It looks like the ram you have may not be compatible with your iMac. I'd try getting another stick of ram and putting it. You probably have a partially dead stick of ram or an incompatibility with that type of ram.
