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.

1802 fixed my continues annoying issue with USB so ill stick with 1802 till newer version.

SSD was missing once in the last weeks. USB was every boot.....

After AMD finally fixed the memory overclocking, I got a chance to play with a really nice board from ASUS. Really fun to overclock, has nice profiles for DDR5 8000MHz but of course you can take things further 😁
The result after a couple of hours is a nice and tight DDR5 8400MHz 36-45-43-38 at VDD 1.55v, vSOC 1.25v and MC 1.4v. Great comeback from AMD with the new AGESA, let's hope they also fix the 1:41, 1:42 and 1:43 dividers...

You are talking about the infinity fabric right? Can you explain that in as much detail as possible here or provide a link?

@matose nice work with your memory OC.
I just run mine at 8000 MHz at the moment:



Level 7

I'm referring to the memory frequency, you can check it in the above screenshot. 8000MHz and above are enabled with the new AGESA versions introduced since June / July 2023.

Sorry the first part got lost i meant the comment about the dividers

Level 7

Don't worry about it! Considering that the BCLK is default at 100MHz, the dividers mentioned will give you the memory frequency and so far only 8000MHz (1:40) and 8800MHz (1:44) work. The second one is very hard to achieve unless IMC is very good and / or cooled subzero.

Level 7

Ah, that's a name I haven't seen in a long time 🙂

8000 and 8800 work and I think 9000 works as well, but my chiller was not enough to successfully post. 8800 was completely unstable, perhaps would be usable with LN2.

Level 10

Guys, maybe some have 1801 bios for ProArt X670E? Someone on says that it supports 2200 fclk with 3300 mclk properly, because 1802 supports, but with errors. Or maybe something new, or maybe when will be stable new bios?

Level 9

@SAFEDISK  Is 1802 coming off Beta, or are we waiting for another official to fix the NVME issues we're seeing?
