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)

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.

LAN disconnect - is it the one that is fixed by disabling energy efficient ethernet in the driver or something else?

Not sure, I've just seen a few mentions about this issue but I have not experienced it myself

7950X3D here too, 64GB Z5 Neo EXPO I @6000 with buildzoid timings and voltages, PBO enabled, CPU boost @200, medium boostit enabled, no async eCLK on my E-A, almost anything else like MCR and so on left untouched
Back from LLC1 to auto LLC so had idle crashes, globally decreased 1303 stable CO by 6 ticks for being stable with 1415 and still refining per core values.
Due to overnight idle validation it will takes a few weeks to get perfect CO.

can you send me the link with the buildzoid timmings?

I think my 7900x is the worst binning ever.

I can't even set -5 in the CO, I tried the Buildzoid video and my system crashes inside the BIOS.

Was anyone able to up the thermal ceiling for X3D processors on 1415? I am unable to post if I choose thermal limit in bios at 90 degrees - get QCode A9. 

Boots fine with limit of 80 degrees.

I think the burning 12VHPWR Cables, "exploding" Ryzen 7000 CPUS are not always the manufacturers fault.  I think there is a lot Error 30 involved like in your case 🙂

I was just looking for the 1415 bios for my mobo and there isn't one for it, there is 1416 for the x670e - egaming. Does anyone know if that is equivalent to 1415?
