    Exclamation Bug in B660 bios cpu voltage offset

    Hi. I made several tickets on Asus support but there is no way to make them understand the problem.

    There is a bug on b660 bios, on all b660 boards. And all 600 series. On z690 is less visible cause there is adaptive voltage, which most people use. On b660 there is only offset.

    Problem is, setting a CPU voltage offset of -0.005 will cause ramdon freeze at idle. As you increase the offset, the random freeze ratio will increase.

    Also setting + offset will do the same.

    This is because applying any offset will cause more than -0.200mv drop at idle.

    This was happening on msi boards too and was fixed with a bios update.

    Please someone from Asus explain why cpu voltage drops to 0.300 or less when using default bios settings. Lowest per spec value is 0.700 for alder lake.
