X670 resource


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


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.

Hi SafeDisk

Loaded 0044 on Extreme board. Why in bios it’s still identified as 1007b?

Its identified as 1007b in bios but when you open it up with hex editor you get 1007C


AGESA 1007C is correct
Since this is a test version, did not change the version name

Nice ! Waiting for Strix-E bios 👍

Nice, just waiting for prime x670e pro wifi

Currently on my ROG Crosshair X670E Hero, I have BIOS 1516 installed and still my Kingston FURY Beast DDR5 RGB 32GB (2x16GB) 6000MT/s DDR5 CL36 (KF560C36BBEAK2-32) RAMs, listed in Asus's QVL as compatible, turn out to send my PC into freeze as soon as I enable EXPO mode.
Until BIOS version 805 everything was working properly without any problem.
I have opened a ticket to Asus and the only thing they ask is to "wait" that they will fix it in an upcoming update.
Too bad that 12 BIOS versions have come out and still the problem is not fixed.
To make my system work the only way is to leave the mode in AUTO and manually set the RAMs to 6000Mhz.

А что за процессор у тебя стоит?


У меня такая же плата и такая же память, процессор 7950x3d... Есть 1 фриз при старте windows , а дальше все хорошо... Как правило проблемы появляются из-за программ от Asus в windows , armory create итд итп

Just a small heads up. It's been almost a year since AM5 CPUs hit the market and now it's time to hinder the performance to mitigate a security issue 😕

The fix will be in the BIOS revision with AMD AGESA and it will for sure have to have a negative impact on performance. Hopefully AMD and ASUS work together and put an option into BIOS to disable this mitigation. Otherwise I'll personally just stick to AGESA

Sorry if this has been asked, I'm trying to get the data from the "Get Boost Curve" button in the tool but it's not returning anything for me.  Running a 7950x3d on a B650E-I (1637) and Windows 11.  Any help would be greatly appreciated.
