Epyc vendor lock

[metebalci]

Is there a way to check if an Epyc processor is vendor locked ?

Yes, you try to boot a system without psb enabled (like supermicro or others) and if it fails with a specific error the epyc cpu is locked

I mean without moving it to another system.

There's an exact BIOS option for psb in some of the Dell and Lenovo machine and options are opened by default.
So if any EPYC processer is originally from dell or lenovo systems, or has been used in those machine, they would definitely get locked

What about HP ? I read they are not locking but also saw some opposite posts.

HPE didn't have psb, at least not on the gen10 series. I have a DL325G10 and 385G10 , they're both free for EPYC's.
Maybe some of the machines are manufactured with psb in some special cases.
