Mac Pro 4,1 (single CPU) -> Ventura == success! Mac Pro 4.1 (dual CPU) -> Ventura == bootloop!

Systems : two CMP 4,1s - one is a single processor, the other dual.
16/32GB of RAM. Fusion drives. RX580 GPUs. Both have been successfully flashed with 5,1 firmware and were running 10.11.6 without a hitch.

I was able to upgrade the single CPU machine to Ventura using OCLP 1.4.3. I was not able to to get Ventura to boot off of the Fusion drive so I installed onto a 2TB SATA SSD.

Tried to upgrade the dual CPU machine. Same procedure, similar setup, using a 4TB SSD. The initial installation goes OK as does the first restart but the installation never progresses past the third reboot - it gets about 35% of the way then reboots. I went back into OCLP and enabled verbose mode but still cannot tell the fault which is causing the install to fail.

Guidance?
