The white sticker on board reads: 630T3984/630-4256

Ouch, I was hoping it wouldn't be one of those.
I think it has to be the same. My info comes from an Apple document discussing CPU upgrades.

Before Replacing the Processor
Important:
Apple has determined a compatibility issue between the processor and certain
fabrication levels of the logic board on some Power Mac Server G4 (Mirrored Drive Doors)
and Power Mac G4 (Mirrored Drive Doors) products. Before ordering a replacement
processor for those models, follow these steps:
1. Open the computer and check the fabrication number that is printed on the logic
board. The fabrication number is easily visible at the edge of the board near PCI card
slot 5.
2. If the logic board fabrication number is 820-1308, 820-1440, or 820-1445, do
not
order the processor module. Instead, you must replace both the logic board and the
processor by ordering the combined module: Module Set, Logic and Processor (Apple
part number 661-3654).
Replacement Warning:
When ordering this combined module set, a returned logic
board must match one of the three fabrication numbers (820-1308, 820-1440, or 820-
1445). If the logic board does not match one of these fabrication numbers, it will be
rejected.
3. If the logic board fabrication number is any other number (
not
820-1308, 820-1440, or
820-1445), order only the multiprocessor module (Apple part number 661-2730).
So make of it what you will. If your email address is in your profile, I'll email the whole document - it's a bible for MDD owners - shows you how to remove and replace everything, with photos. It's only 3.3MB.
