4 UAD1 in OS9 crash system

4 UAD1 in OS9 crash system

I installed Magma with MDD computers, three systems: 10.4, 10.5, and OS9. With 4 cards, OSX works perfectly, but it crashes in OS9. With three cards, it works perfectly, but 4 doesn't. I tried swapping the cards, but nothing changes. Software version 3.9 should handle them. Extension conflict? I have no idea. Can anyone give me some suggestions? Does anyone have 4 UAD cards in OS9 and they work? Let me know.

I only did a max of 2 (UAD-1 Mackie version) and a single Power Core or 2 Power Cores. 

I think you might be either

1) Maxing out what the software was designed for
2) Hitting a PCI bus mastering ceiling or DMA conflict, since I believe those cards are bus mastering

I don't think it's the master bus otherwise it would give me problems even OSX. In OSX I tried to make some test songs overloaded with both UAD and Powercore plugins (I have 2) and they didn't give me any problems. I tried the Makie software in OS9 but it works with a maximum of two. In OS9 with software 3.9 in "configuration" it gives me 4 slots to use so the software allows for a maximum of 4 cards..uhm..a mystery. Yes, you could say "use 3 which is enough" but I'd like to understand where the problem is..let me know

it could be a difference caused by the OS which affect the PCI bandwith.

does it happen with the current project? or did you also try it with only 1 plug-in yet.

Interesting theory that the system has PCI bandwidth limitations... in fact it must be the system because with 4 cards it just won't boot! Perhaps some extension is causing a conflict? I'm attaching photos (sorry if they're ugly) with the three cards in the OS9 control panel (it also provides a fourth). In OSX with 4 cards it works perfectly, and the photo of the system that with 4 won't boot in OS9, gives me this strange screen right away.
