Fully populating an OctoRAM card (Q)

[EWING@CTRVAX.VANDERBILT.EDU (Rick Ewing)]

I have just received 4 megs of DRAM from a Quadra 950 which will no longer
be needing them.  I have attempted to put them into the last 4 rows of
my OctoRAM card (R.I.P MDIdeas) and have the set proper jumpers for 8
meg operation.  Yet my GS refuses to boot properly anymore (it just starts
and then dumps to the monitor early on) even though it thinks it
has 8 megs o' RAM in the RAM disk CDA.  The built in memory test
seems to think everything is okay, but I have no way of knowing that
its going after the upper RAM in the test.  I know people have put 8 megs
into GS's before, but I can't!  The memory is the 1 Meg x 2 style which
means that only 2 chips are on the SIMM boards, unlike the existing
ones that are 1 x 8's.  TYpically, I wouldn't expect this to be a problem,
but who knows?  Does anyone out there have an idea on what could be
wrong here?  I have reseated the memory three times with no success.
