Check when all cores are working please, for example on CB20 multi-core test.

Indeed it works better performance wise if you can keep lower temperatures, but I think the voltages used are too high for all-core boost and the negative offset doesn't seem to work.

I tried to put 110 on thermal limit setting but didn't do any difference compared with 0.
It's on auto

PBO still pushes up to 1.416v but my cooler keeps temps under 62c. I didn't see any dropouts under full load. Now it even works better, pushing several cores to 4.3+.
Still don't know what to do with that thermal limit setting and left it at 0. Maybe feature for next gen ? Maybe all will work better ?

Without negative offset, PBO is unusable for me, there's no point going to 1.38 for 4050-4075 on CB20. Boost starts from 4150 (+200 over 3950 when PBO is disabled) but with so high voltage, it immediately drops down to 4075 or 4050 due to temps going 70+.

I also still have a screen with a cursor in top-left corner for 1-2 seconds when booting (before the ASUS logo is displayed). This appeared on 4804, I never had it before. I went from 4204 to 4804 and now to 5007.

That's setting I'm keeping mine on, no problems encountered.

Tnx, that looks like it will be pretty universal BIOS,
What do you know about settings for "Platform thermal throttle limit" I don't hit 70c, it's mostly hovering around 62 - 65c at most but is sometimes feeling like slight throttle down,
