    VCCIO and System agent high voltage or not for Auto?

    Is it ok for 11700k ,Z590-f and overclocked ram to 3733mhz leave VCCIO and System agent in Auto and get VCCIO around 1.43 V and 1.38 V ?

    Hi rolani4

    Those voltages are a bit high, would set VCCIO and System Agent voltage manually to 1.25v and see how it goes.

    The VID tables are too high to leave anything in auto since 10 series came out.

    Thing is 1.25v may not work for Gear 1 @ 3733Mhz. More likely it will work for 11 gen i9 CPUs but not i7 11700K coz its memory controller requires more voltage (same applies to vcore voltage for 11700K) because of worse silicon. i7 just need more juice for stable run. 1.25v SA\Mem OC it's more Gear 1 @ 3600Mhz voltage. (system may boot Gear 1 @ 3733Mhz but 90% it will be unstable under stress load with this voltage).
    Meanwhile 1.25v SA\Mem OC can be sufficent for Gear 2 @ somewhere around 4533Mhz.

    it's an Asus thing, this is how they know to do things, they increase the IO/SA voltages a lot as the frequency goes high
    for 4000MHz, these are 1.40V/1.50V - it's... normal... it's an Asus...
    you might tune them or leave them alone... 10thd and 11th processors can handle Asus settings in the end
