MP 7,1 Mac Pro 2019 CPU Upgrade, RAM even after PRAM Reset still at 2666 MHz despite using 2933 DIMMs

[Dt990]

Previous with my 8-Core CPU I had bought all 2933 R-DIMMs for when it came time to upgrade, and here I am, with a w3245m.

Is there a trick I'm missing for getting a Mac Pro 2019 to re-register it's RAM after a CPU upgrade to 16-Core? With the old cMPs 5,1, when upgrading, you could bump the 1066 to 1333 if you had the correct DIMMs.

Remove all DIMMS. Put highest capacity DIMM in Slot 1 of any channel. Boot. Is the DIMM registering as 2933MHz? If so, add DIMMS back in the proper channel configuration.
