YouTuber and extreme overclocker De8auer has gotten an Epyc CPU working on an X399 Threadripper motherboard.. sort of. In his testing Der8auer has found that there is a single ID pin on Epyc that when covered, will allow you to partially boot an Epyc CPU. The BIOS stopped loading at memory checks, so a BIOS that is compatible with Epyc is required, but this proves that the sockets and pinouts are the same.





Quite amazing stuff. I have my doubts if a partner will ever release a BIOS that allows Epyc in an X399 motherboard, but it opens up possibilities for sure.
