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

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)

strix 670 itx



for crosshair and strix e-e:

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.

My processor is 7950x3D. Since Bios 1004, my processor temperature has been rising and falling up to 90 C°. Is this normal?

Yes, tends to be hot, but you can set a temp limit for throttling in bios like 85C and also control temps by lowering different voltages as much as possible without causing instability.

You can also limit TDP if you like, to control temps.

Needless to say, such a CPU has to have good cooling.

1410 applies ~ 0.6V additional VDD/Q when High Voltage Mode is enabled for Richtek PMIC (as in Teamgroup UD5-7800 or UD5-7200). seen on crosshair and strix..

New bios with AGESA (For x670e-extreme from 1401 to new 1410) and remember that's BETA BIOS

Newer versions usually appearing pretty quickly here.

However I am quite reluctant to just download and install a BIOS from any other source than board manufacturer. Specifically MSI warned recently as due to a data breach authentication keys were stolen and unauthorized with BIOS with potentially unwanted extensions or malware might appear. You certainly don't want that. It's sufficient already having to disable Armoury Crate bloatware in stock BIOS.

So unless you feel very adventurous I would recommend to wait until this BIOS appearing on official download pages.

@Shamino when will we get a new BIOS with official support for high-density RAM modules. I am still running 1003…

Level 9

Which bios for 48go modules on X670E-I ? Looking to pull the trigger for my little server build ?

I recommend you new agesa and wait

Level 7

one question if i have a kit ram XMP/EXPO what profile i see in the bios?

I hope the 1410 BIOS revision wasn't done only to add a hilarious new disclaimer / warning when you enable EXPO now - "this counts as overclocking and we won't cover it if it blows up your cpu" -
