I've got a SP3 socket Epyc 7351P CPU and the availability of motherboards is kinda limited. I was hoping to find something that is small form factor. In doing some of reading, I found that Socket TR4, is physically identical to a normal SP3 socket, but a TR4 socket will prevent the use of CPUs designed for Socket SP3 with an ID pin. Socket sTRX4, is also physically identical to the normal SP3 socket, but I can't find any information if a SP3 socket CPU like the 7351P I have will work in a sTRX4. Does anyone happen to know?

Hello diarmuid‌, the AMD EPYC processor will only operate in the SP3 socket.  Likewise, processors intended for TR4 or TRX4 sockets will not operate in SP3 sockets.  So you will have to purchase an SP3 motherboard.

Thanks for the confirmation, appreciate the help!

The answer is no.

Pro overclocker, der8auer, actually tested this config in TR4 with an EPYC CPU and found that it doesn't POST.
