14900k & ROG MAXIMUS Z790 HERO using BIOS 2602 core multiplier downclocking

[avihay_1989]

Hi,

I notice since the last BIOS upgrade to 2602 that the P-Cores & E-Cores ratio \ Multiplier keep downclocking even while I set the settings in the Bios to "sync all cores" for  P-cores: x55 and for E-Cores X44.

I used all the intel recommendation setting for PL1 & PL2 = 253W, and time

AI Overclock tuner: XMP1

Intel adaptive Boost technology - I tried all options: auto, disabled, enabled

Asus multicore Enhancement - disabled - enforce all limits.

SVID behavior : I tried Intel fail safe \ typical scenario  

Performance Core Ratio: sync all cores x55

Efficient Core Ratio: sync all cores x44

CPU Load Line Calibration Level 4

Internal CPU Core Managment:

Unlimited ICCMAX: Disabled

CPU Core /Cashe current LImit Max: 400A

Long Duration package power Limit: 253

Package Power time window: 56

Short Duration package power Limit: 253

Dual Tau boost: disabled

IA AC Load Line: enabled

IA DC Load Line: enabled

Thermal Velocity boost: I tried all auto, disabled, +2bin 

Ring Down bin: I tired auto\ disabled.

Min CPU cache ratio: 50

MAX CPU cache ratio:50

Global core SVID Voltage- manual -> 1.365V

Using the CPU-Z & HWINFO I can see that all P-cores & E-cores ratios downclocking to very low values!

example

P Core0 - Pcore 7 > reaching 3000MHZ and sometimes the raio being x8 = 800mhz.

Ecores- reaching 800Mhz as well

the ratio is not reflecting the UEFI settings,

I tried reset the CMOS , load optimized defaults, the issue reproduced.

what AM I missing here?

I'd like to update using those settings as I shared in the pictures below the boost is working as should be at 5.7 for P cores and 4.3 for E cores consistent without drops with minor rare drops from some E cores during heavy game such as Wukong.

I'd like to understand what changed that I can't have the same performance as before using the settings from the before as I shared in previous message in this post.

Hi @avihay_1989 it is my understanding that the most recent BIOS with Microcode 12B from ASUS has lower C1 States enabled in the BIOS which cannot be disabled via any of the standard BIOS settings. So High Performance and Ultimate Performance profiles in Windows work exactly the same like Balance Profile when it comes to CPU Usage. This is mentioned in the BIOS update and most people are not happy about ASUS forcing this change. The official message from ASUS is that this change is done as per latest Intel Guidelines that came from Intel with 12B Microcode.

If you download to 1 version back with Microcode 129, it is best to CLEAR CMOS and then load F5 defaults. Then you can slowly begin to make the changes you like to make.

I hope this information helps you out.
