Z690 Steel Legend Reporting WRONG CPU

I would immediately return that CPU. It's a fairly common return scam, people buy
both a high end and a budget CPU of the same socket type then delid them both and
return the cheap one with the heat-spreader (and all the screen printed info) of
the expensive one. It isn't as easy to trick boards into thinking one CPU is a
different one these days, not since the CPU's themselves began shipping with thier
own locked firmware identifiers.

Odds are, if it's reporting as a Celeron, it's a Celeron disguised as an i9.

Good luck.

Turns out that the cpu was incorrect - somebody did a return product scam and swapped the CPU and repackaged. I did not verify when I popped it into the board (my error). Lesson learned.

All is good now I9-12900 performing as expected. Thank you.
