sTR5 socket vs SP6 socket

I recently purchased an Asus Pro WS WRX90E-SAGE SE mb. This board arrived with a CPU socket marked "SP6" and not the "sTR5" designation I was expecting based on the text description on the Asus website. The markings on the mb package clearly state "sTR5" in several places, yet there is a photo on the package which shows a mb with an "SP6" marking on the socket. I have looked at mbs from other manufacturers stating "sTR5" socket and all of these show a socket marked "SP6" in the photos of the mb. It is my understanding that the SP6 socket is not compatible with the sTR5 socket, having the same number of pins, but with a different pin-out. I'd like to clarify what is going on here before risking a high dollar CPU on this mb. Guidance appreciated.

Yeah this one confuses a lot of people.

The “SP6” marking on the socket usually doesn’t mean the motherboard is actually SP6. On a bunch of WRX90 / Threadripper Pro boards, the metal retention frame is stamped “SP6” because the hardware/loader design is similar, but the board itself is still sTR5.

What I’d do before dropping a CPU in:

1. Confirm the exact board model printed on the PCB (not just the box). If it says Pro WS WRX90E-SAGE SE, you’re fine.
   
   
2. Check ASUS CPU Support List for that board. If it lists Threadripper Pro 7000 WX chips, then it’s definitely sTR5.
   
   
3. Make sure the CPU you’re using is Threadripper Pro (WX), not an EPYC SP6 chip.
   

If you tell me the exact CPU model you’re planning to install (example: 7975WX / 7995WX), I can confirm for sure before you risk anything.
