Everything worked OK, there was an XMP profile at 3200, turned off the computer, rearranged the coolers, then refused to start , when starting 3 short beeps of the speaker, and after several restarts, the bios is reset to the default 2400 frequency, xmp does not turn on, refuses to boot.
I reset the bios to default, rolled it back to early firmware, then back, nothing helps, the two-channel works. I repeat, I didn't break anything, everything was ok for a long time, and the percentage in the gilded frequency worked stably and perfectly for several months.
