Question Gigabyte X570S Aorus Master showing POST code FE ?

Mar 5, 2023
I built a new computer two days ago.

gigabyte X570S aorus master
amd ryzen 7 5800X
team vulcan z 3600 cl14 14-15-15-35
phanteks amp 750
xfx merc319 6750 xt black

yesterday i got the POST code "FE" and I see in the manual it states "reserved for future AMI errors ", though i see everywhere online others with FE code that it's a memory seating/heatsink or pump seating issue. reseated both, actually RAM i reseated three times, cleared CMOS, checked all cables, ran memtest86, no errors, FE code still shows up. anyone else have this problem, or know how to fix it?
