Thanks for these updates! Unfortunately I don't have a Z370 Classified, but I have a EVGA Z370 Micro.

I've found out that it current limit throttles with my 9900k (XTU shows Current Limit Throttling and TS shows EDP other). There is no configuration for current limit settings in BIOS, and using XTU or Throttlestop does not prevent current limit throttling.

Would it be possible to unlock current limits with a custom Z370 Micro BIOS?

EDIT: I was able to remove Current/EDP throttling by using Throttlestop and changing Power Limit 4 max value to 0. No custom BIOS needed anymore!

Same request as Ceevee. Would love for someone to remove the current throttling on the evga z370 micro board. Or does anyone know the steps involved?

I have a post up on request to mod evga z370 micro
[REQUEST] How do i mod EVGA Z370 Micro/help me mod this?

Do as ceevee, use Throttlestop.

A note for those with the Z370 Classified K and a P0 revision CPU with CPUID 906EC (e.g. i5-9400 P0, i5-9400F P0, i5-9600K P0 & i7-9700K P0 & i9-9900K P0) the 84 microcode lowers the voltage table when using adaptive voltage with offset (see images below).

How long have you used this mobo and the Gigabyte one already with those Overclocks?

@lime I have been tuning my overclock since May 2019 for the EVGA Z370 and since July 2019 for the Z390.

@Oneshot The 9900KS I have now is much better silicon than my 9900K P0 or my 9700K R0, see the images below for my BIOS settings at 5.0 GHz all core with RAM @ 4133 MHz;

[Edit] Note that this BIOS has earliest Coffee Lake microcodes to avoid performance penalties, if you want the latest microcodes for added security you can use UBU to update all of them at the same time.
