The original Qube 2700 uses 5V 72 pin PS/2 SIMMs. I believe it's EDO
and not FPM, but I'm not certain about that.
Raq2, Qube2 etc use the rare 3.3V 72 pin EDO SIMMs.
DIMMs are something completely different, significantly wider than
PS/2 SIMMs, and won't fit in the sockets, much less work. You
may have dual sided SIMMs with chips soldered on both sides, but
this is unlikely to be a problem. I'd think it's more likely that
your Qube doesn't like the organization, i.e. it doesn't support
the number of CAS lines required and leaves one unused.
