x470 taichi bios 3.43 PBO gone mad

hi
it seems to me that with v.3.43 pbo has gone.
I can freeze the system simply moving quicly the mouse in firefox, or move a rendered room in sweethome3d, or launching quicly gimp, firefox, darktable...

cannot even disable it, or, more precisely, it's disabled in bios but my cpu monitor frequency is still showing spikes above 3.7 GHz and even above 4 GHz

now I disabled xmp ram, put cpu offset voltage to -0,1v, the two LLP to 1 to solve, but is quite sad

2700X do boost to 4ghz naturally its over 4ghz where its using xfr/pbo

increase the offset to see if it works

-0.1v makes it unstable
you need -0.09 to -0.07v

that only means you and me drew the worst in the lottery

this is nothing new to me unstable = more volts simple as that

and its been like this for me since pbo got enabled i always have to adjust the offset i forgot which bios that defaults it to -0.1v but that made me not able to boot up the system
