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.

On my x670E Hero there is no such option. And with all nvme enabled on 1905, PCIE_1 is @16, and it;s not limited to @8 like on your screenshot.

bro what is the change between ComboAM5PI and FireRangePi ? just a name or micro code changing like a OpenSIL ?

can i ask for 2613 version ? asus prime b650m-k 



Level 10

Just flashed to 2004 bios and guess what guys......... YES - still infinity boot/reset with integrated gpu disabled.

GRATS ASUS - good job.

Sorry bro
long holiday here We will check the issue next week.

Look also into this nvme issue. It's regression, very annoying regression.

Level 10

I'm on X670E-I and 2610 also has infinty boot/reset if iGPU is disabled on this MB.

Level 8

I installed BIOS 2004 on my ROG CROSSHAIR X670E HERO today. Now only 3 out of 4 NVME's are recognized. Slot M.2_2 is no longer recognized. But the NVME is definitely not broken.

I had to enable M2_2 in BIOS on my Extreme. I think it's under the Additional Devices, one of the options. I'm on the streetcar going to work, can't find it right now. It might be under the PCI-e lanes settings.

Level 9


any chance we see 8200+ multipliers unlocked?
