Precision 5820 motherboard two chipsets
Chino alerted us of the nuances of this Dell pc model
Dell essentially made two distinct lines of pc
one called 5820 tower
the other called 5820 tower X-series
Both have LGA2066 socket
one for Core X cpu (X299 chipset)
one for Xeon cpu (C422 chipset)
The X299 chipset mobo only supports Core X cpu
The C422 chipset mobo only supports Xeon cpu
I ran down a half deep rabbit hole
C422 chipset mobo
for Xeon cpu

I think you are missing at least one, 472R4! That's the motherboard I have. It came with a w-2123 originally, but I wanted to upgrade so I got a w-2255, and the bios is up to date but it just power cycles. I ordered a w-2155 because it boos fine when I put the w-2123 back in so I am going to do some investigation.
