GS RAM on ROM 3 machine

[rsjoyce@eos.ncsu.edu (ROGER STEPHEN JOYCE)]

Got a little problem.  I recently upgraded (new motherboard) from
ROM 1 to ROM 3.  In the old ROM 1 machine I had a GS RAM from Applied
Engineering (it was in it when I bought the computer second-
handed).  Anyways, the GS RAM doesn't like the new motherboard.
The ROM 3 machine has 1Mb onboard plus a full ram card (1.5Mb) should
be 2.5Mb, but the control panel swears it has 3!  The machine runs fine
until I have had several applications open one right after the other,
when it will unexpectedly crash.  I suspect that it is trying to
address nonexistent memory.  I tried the GS RAM on another ROM 3 machine
and it does the same thing, but on another ROM 1 it behaves beautifully!
Is it a problem in the II gs or the GS RAM??  Does AE offer a cheap or
free fix or upgrade?  Has anyone else had this problem??

BTW:  I've already narrowed it down to the memory card.  All other
cards (accelerator, SCSI card, modem, 5.25" controller etc. didn't
contribute)

Thanks.
