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.

Just flashed from 2001 to this 2003 and........

YES - it is still CRAP - restart loop after disabling integrated gpu. Great work - just great.

Level 11

And another downside is if you have nvidia primary GPU and AMD iGPU is that you have to have both nvidia and AMD gpu drivers installed. Not sure if that can cause any issues to primary gpu but for sure it's not something I like

Level 9

You'd think that a new BIOS that is based on the old BIOS wouldn't introduce new bugs to settings that literally aren't changed between the BIOSes. Oh well...

Level 10

I have a Pulse 7900XTX and keeping iGPU auto is ok. Can boot, same settings in BIOS as before (EXPOII, memory context and UCLK=1).

iGPU disabled is bootloop...

2003 works ok with my system 

Level 8

2003 seems to be working fairly well for me SO FAR.

I had time to run the Cyberpunk 2077 benchmark a few times in Windows, and the RDR2 benchmark once in Linux. No crashes. It will take some time extended time to determine how stable my box truly is.

Under FreeBSD, I still get lockups with a IO load under the SATA drive I'm running it off of, but for the first time 1709 broke things, the onboard Intel nic actually works!

Level 9

It took them two months to bungle 1905. What a mess.

Level 7

X670EE updated to 2003 and one of NVME SSD on  ROG GEN-Z.2 doesn't show up. it's a WD SN850 2TB SSD.

Level 8

After spending more time with 2003... Seeing the same random lockups as with 1905.

How much are these issues specific to Asus compare to the x670 et al chipsets? Is this a platform or a vendor issue? Some of both?

Level 9


any chance we see 8200+ unlocked for zen4?
