Tried v1.70 a12 Dev to mod µC for ASUS Z370 with CPUID=906EA
Used Options 5 -> C -> U -> Enter -> 5 again.
I do observe 12 cpuid detected before modding and only 8 detected after modded done.
Is it normal ?
Here are the screenshots (from left to right: Choice_5 > Choice_C > Choice_U > Choice_ENTER > Choice_5 after modded done):

Some of the microcodes are Engineering Samples. If you need them, then you can add them by editing MCUpdate.txt.
In fact, the procedure for updating the microcircuits is the same as in previous versions of UBU. Only now the necessary microcodes are written by the user independently.

From your screenshots I do not understand one thing, I do not see the restoration of the FIT dump.

@SoniX
I must try a different version of Microcode???
Is there another for Skylake-X???

Hi again, @SoniX

Did what u said and this is the result:


Is it correct or is there a problem with fit mismatch???
Thanks again.

EDIT by Fernando: Inserted image resized and re-attached (to save space)

At you on a preview, that is before updating one, and after updating absolutely another.
The result should coincide with the preview.

I just included all the microcodes present in original bios.
If i didn´t edit the mcupdate.txt, the option c would only update the 50654 microcode.
This is the file with microcodes updated, can u check it to see if is correct???

Thanks.

Does your processor belong to Engineering Samples?

If your processor has CPUID 50654, then it was sufficient to specify another file with a microcode version, for example 3C with the same CPUID.

My processor is retail, it should work with 43 microcode, if this includes 7980xe's.
I also thought like u, 43 should be enough, but there is some kind of problem and cpu remains at 700MHz.
Could the modded efiflash have something to do with it??? It is 3.62 version, and original bios's for Gigabyte x299 come with 3.65.
In regards to 3C version, there is a original bios from Gigabyte, F3b, which includes it. I am trying to use the new 43, as other mates are doing.

As far as I understand, 43 microcode is a beta version.
In general, everything is tested by testing, that is, comparing the work on different versions of microcodes.

Intel ordered to retire the 3A and 3C versions, so 43 should be better than those. That's why I want to use it.
Could u mod the efiflash 3.65 to let flash modded bios's???

No problem for me with microcode 43 (with UBU) and Asus bios

I know, tistou77, I saw u modded the Rampage bios. But Gigabyte is not working with 43 and my 7980xe, it gets fixed at 700MHz and don't know why.
I am pointing to Efiflash, was using the modded 3.62 version from this forum, when the new bios's for x299 come with 3.65.
I wish Gigabyte had an utility like Asus Flashback, it would be easier...

@Sonix

On screenshot "Choice_U" you can observe the message "Dump _FIT_ restored".
It should be ended with an exclamation mark character (!) to be visible like for the "Dump _FIT_ created!" message.
Is it normal to get only twice "Update Microcode Patch ...OK" message ?

If I understand this UBU Tool version does allow to automatically update the µC for "non engineering samples CPUID" without effort ?
This is an excellent choice, my BIOS does not need to support Engineering sample because I am a 'user' and not a 'beta mboard manufacturer tester' !
I don't understand why ASUS does deliver official BIOS which does support beta sampling CPUs. It should be supported by "beta BIOS" not by "official BIOS".

So, in my example can you confirm the original BIOS is now correctly modded and does support up to 8 standard CPUIDs in place of the 12 original CPUIDs ?

@ vmanuelgm
Try it on a stable version of BIOS.

@SoniX
u mean the microcode 43???

I tried it both in F2 (stable) and in F3b (beta), and 7980xe got fixed at 700MHz.
Then I reflashed F2 with 3.65 efiflash and all ok again.

EDIT: sorry, efiflash 0.62 and 0.65, not 3.62 and 3.65
