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

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

hi,
it seems working now.
Thank you

Are these your findings? anyway why they don't put it in the default setting? with auto in each setting it is completely unstable, often doesn't boot in linux (with strange errors in the logs when eventually boots) and in windows it's even worse

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

You're right but i think that once they added some bucks to the prices to add an X they should have tested that it works at least with auto settings.
I think is more up to ASRock to adjust they settings.

That said I put -0,1 according to the firs bioses.
Now I'm at -0,0875.
That allow up to 1,442v.
It's true that is for seconds, but if you execute an intensive task it can lasts minutes.
I think isn't so safe.

Any way that's our bad luck
