I noticed this oddity while investigating why my undervolt in XTU (22.214.171.124) is not sticking after rebooting. So, there is a "default" profile in XTU which is meant to bring the settings back to normal. But my default profile is weird. These are its settings, which I find questionable: Turbo Boost Power Max: 30.000 W Turbo Boost Short Power Max: 67.000 W Turbo Boost Power Time Window: 16 seconds Processor Core/Cache IccMax: 245.000 A Before I could notice that there might be something wrong with these values, I applied them, but I noticed that these settings too, just like my undervolt, don't stick after rebooting (EXCEPT for Processor Core/Cache IccMax, these two stick). The system reverts to these following values instead, which maybe are the REAL default settings? Turbo Boost Power Max: 125.000 W Turbo Boost Short Power Max: 160.000 W Turbo Boost Power Time Window: 56 seconds Processor Core/Cache IccMax: 210.000 A The default XTU profile cannot be overwritten, so it's not possible that I accidentally messed it up and created a wrong default profile. So which settings should I have? The first set, or the second set? Or something else entirely? And who made that default profile? XTU itself, detecting things automatically? Or...? And while we're at it, any clue why my undervolt (-0.120 V at Core/Cache Voltage Offset) doesn't stick after reboot? The (yet another) strange thing is that, after rebooting, this value of -0.120 V doesn't show up in the Active column (in the top right of XTU), which shows the default value of 0.000 V instead, BUT it does show up in both the Default and At Boot columns in XTU (the attached picture doesn't show this). Like, the undervolt setting is being remembered as a default/at boot value incorrectly (because it should be 0.000, right?), but it's not being implemented as an active value?
