More than 128 mB on a CSPPC?

There might not be a limit if you patch exec or other functions like they had to do with the Vampire 2 on the A600 (and A500 I believe).

It was stated on http://www.apollo-core.com/knowledge.php?b=5¬e=2047&x=1&z=L4DAbc that there is no physical limit.  What exactly that means is not clear.  Software or electrical is still possible.

Interesting thread over there. With the speed of that bus and really fast memory I would be very surprised if you could fill .5Gig.
