ill use this thread to collect some new test bioses for the boards, maybe also to explain some less understood options

to disable cores ccd go here and choose ccd xx bit map down core.
each ones stand for an enabled core
best to disable from the back, ie:
instead of 0011000
after selection press downcore apply changes or discard if made mistake

octool port to linux

7950x not boosting pass 5.5G -> check that CStates is not disabled
Detailed Explanation on CState Boot Limiter

Test BIOSes:

X3D OC Preset for those MB with asynch BCLK Support: (for simple slight perf boost for X3D)

DOCP/EXPO Tweaked: (for simple timings tightening)

explanation of segment2 Loadline:


customize a heterogenous loadline for a dual segment workload range.

example above shows loadline=L6 when current is in range of 0~40A, and Level4 when current is above 40A.




Adds for x3d

dynamic ccd priority switch with core flex, os / driver agnostic so win10 win11 ok



Algo as follows:
If condition reached and ccd0 specified, then check current mem/cache activity > threshold and hysteresis reached, if fulfilled then switch
If condition reached and ccd1 specified, then check current mem/cache activity <=threshold and hysteresis reached,, if fulfilled then switch
Default hysteresis =4

Can combine multiple algos for ccd priority so combinations are wide

works on non x3d too but of course senseless on it. detailed explanation here.

Near cpu socket: On X670E proart I have one there- though no silkscreen text near mine, it looked like potentially a header for flashing the winbond chip right next to it (assuming uefi). If you’re wondering if it will interfere with thermal grizzly offset adapter, it will. Could be removed, but at this point probably best to keep your warranty intact.

Also on x670e proart all stock photos show an additional two pins in the row with a jumper cap on them, but have not seen that populated on a board in consumer hands. 

Near the bottom of the board, looks like lpc debug possibly? I have one that looks the same labeled as such near there - but also have at least one more that looks identical with no label..

Side note- does anyone know if the Asus LPC debug card is compatible with am5 boards, and if so, how to get a hold of one? Been revisiting its dead end product page since my x570 board

It's a header for spiflash, if there's a jumper it's a dual bios board, it's mainly meant for in house testing and for service/repair

I think this whole brohaha with the disappearing legal notices is much ado about nothing. 

We are forgetting a very useful maxim here, "Never ascribe malice to what is easily explained by simple incompetence."

Installed BIOS 1415 yesterday - x670 extreme, 7900x, 32 GBG.Skill 6000 C36 QVL,win11 with all latest updates, latest chipsetdrivers installed,

This is the first BIOS where i have 0 Errors in Karhu, and Aida Stresstest with MCR and PD enabled! Very good Boottime is around 35 sek -which was before 1:20Min from PowerButton to Win login

GPU is now (so far) initialised correct with PCI 4.0x16 Speed and all Sensor data (before sometimes GPU was not found after startup


SoC is not going above 1.3 V now!
I set ABCLK to 101, FCLK to 2033

when USB 4.0 enabled - mouse stuttering still exists. I still have to disable USB 4.0 / Thunderbolt in the BIOS

The mouse stutter is a Windows issue. Go to device manager > system devices > Thunderbolt. 

go to it’s power management tab and disable it altogether 🙂 all stutter will go away immediately and all apps that cause stutter will behave normally.  

Keep TB/USB4 enabled and at full speed in bios.

Bit the bullet and upgraded to 1415 this morning, after skipping the last few BIOS updates due to the huge number of problems reported. I am quite uncomfortable with anything but the most basic changes right now, but I figure that getting onto the 1415 BIOS revision that is less likely to fry my motherboard or CPU is preferable, especially now that Asus seem to have come to their senses about liability for using it in the first place.

Very simple config:

  • AI Overclock Tuner - DOCP 1
  • CPB - Enabled
  • MCR - Enabled (in both locations)
  • Power Down Enable - Enabled
  • Armoury Crate - Disabled
  • Integrated GPU - Disabled

I was blue screening without Power Down Enable being switched to Enabled. This didn't used to happen in older BIOS revisions (I think 0905 ?) but seems to be absolutely necessary for MCR to work at the moment.

Right now I can boot to desktop in 25 secs and I can run Cinebench, OCCT and AIDA64 stability tests without failing. I am sure there is a lot of safe changes I can make to improve overall performance, but I think I would like to just wait for a few weeks and see if games, software and productivity tools run without issue.

X670E Extreme, Bios 1415.
All Settings to default. Not possible to boot in EXPO or EXPO II.

Ram Kit: Corsair CMT32GX5M2D6000Z36 32 GB

Not on QVL I presume? 
And even if it is on a list, it’s an exact same issue I had aside from having 3x32G dominators. Zero reliability with Expo. 

it’s a shame because visually RAM is striking and customizability is amazing (aside from iCue). 
For piece of mind I have with 2x32G G.Skill (only approved kit) and been working fantastically. 

Just checked it. This Domionator was removed from QVL. My original Kit was a Vengenance one and I bought the actual one because of Asus Support and QVL List. Talked to them afterward, and they confirmed my actual Kit is (now was) on the list. I'm pissed!!!!!
