Ok, on my Alltech Sirius RAM card, I used 8MB without a problem.
I had a ROM 3 and here is the strange part: I had to populate the
card with 8MB.  If I populated the card with 7MB, which should have
resulted in 8MB total on a ROM 3, GS/OS would see 8MB but
there would be problems.  Almost like there was a 1MB hole in
the memory.  So try maxing out the card and see what happens.

The other thing I had to do was turn off DMA on my Apple High
Speed SCSI card.  Many csa2 users got on my case for trading
DMA on this SCSI card for 8MB but 8MB let me do what I
wanted to do (like record big sound samples and load up the
IIGS with system sounds that actually sounded good) and the
loss of DMA, at least on this SCSI card, made little difference.
The card was fast even without it.  I was more impressed with
the Apple HS card with DMA off than I was with the RamFAST
card with DMA on.

With 8MB on my Sirius (rather then 7) and DMA off on my
SCSI, my 8MB ROM 3 ran everything I threw at it and did so
rock stable.  That was with an accelerated accelerator card
too.

Note:  The ROM 3 is not like the ROM 01.  You could have
5MB, not just 4MB, total with DMA on.  The 1MB on the
motherboard is not affected by memory slot addressing
problems so go ahead and add one more megabyte to the
card.
