Upgrading my new 7820

Recently purchased a Dell Precision 7820.  It's a dual processor set up, with silver 4110's and I am using a 2080ti

I wanted to upgrade the processors and got a good deal on a pair of 8252c processors.  They are supposed to be compatible, but I must be missing something.  

When the machine starts, I just get a couple of orange blinks and the machine restarts.  It does this over and over.

What I have done so far is:

Update the bios to latest

I removed the ram, down to two sticks (correct speed ram installed)

Removed the second processor.

Same issue.

I have left the machine with one processor and reinstalled the 4110 and the machine is running with the one.

Anyone have an idea?
