Thanks for testing for us, I’m waiting to pull the trigger on the 7,1 until I know if the cpu can be upgraded, and if we can use standard GOP pc video cards.To anyone that says this can't be done :

Good news is I figured out how to do the install .
Xeon Gold 6212U 2.4 GHz 24 Core in a real Mac Pro 7,1 . She booted up right away first time .
For what its worth , I disabled SIP , Secure Boot and permitted boot from external drive before I began .
She's stable , ran a benchmark and let her idle for three hours .
Bad news is I made the mistake of PRAMing the System and now she won't boot :-(
I suspect its SIP related or is some sort of white list involved ?
And ... I can't figure out how to remove the PRAM battery . Hoping maybe it'll help reset something .
