On the Voodoos I have the big silver ones that have the pushpins through the heatsink are the V3-3000@166MHz and the ones with the smaller black heatsink glued to the chip are 143MHz. If you're in doubt you might consider underclocking it down to 143MHz in the Devs:Monitors/Voodoo tooltype.

Interesting reading regarding Deneb DMA incompatibilities with mediator 4000Di. I wonder if those issues had been addressed by the time the final firmware was released for the Deneb? I ask this because in all other instances the Deneb appears to work fine in DMA mode - I've copied several GB of stuff from ide to Deneb USB stick with no issues, and I can run mp3s off a USB stick on the Deneb to the prisma megamix with no issue. The only lockup occurs when trying to execute Sonnet stuff from a USB stick when the Deneb is in DMA mode.

Zorro III address setup and hold time is increased to ensure operation with that bus board.
Ask Michael Bohemer? He's a very amenable guy who usually responds.

I don't know how the Sonnet works. Or how it interacts with AmigaOS. The USB stack, Poseidon, together with the Deneb driver determine how and where the data gets from USB into RAM. Perhaps these USB read data buffers are in a particular RAM location not accessible via Sonnet? Can the Sonnet access all RAM in the system? CHIP RAM, motherboard FAST RAM, Zorro III FAST RAM etc.?
