Just wanted to say thank you for the guide and for figuring out how shady Intel was with this sh!tty move of them.

This is a breeze for MSI motherboards. Was able to scavenge an i7-9700k, took me maybe 10 minutes, flashed via UEFI M-Flash option, no faults whatsoever, put it on my MSI Z270M Mortar, profit!

-edit-
progress has been made apparently i updated the files wrong.
now i am stuck on "error 4001: fv size too small
the required FV image size 0x3b1008 exceeds the set FV image size 0x3b0000"
when it tries to rebuild the image after the acpi table fix.

using msi b250m bios

not trying to complain or rush anybody or anything, just reporting my findings

@paranoidandroid
Fixed in latest version.

Do you know what’s the best processor that I can run on an Asus Z170 Deluxe with this mod? 9900k?

@gpvecchi
with 2xxx version bios, it should work.
PS: recommend use fixed voltage and disable SVID support.

help me

Hello, I have a Asrock z170 pro4s and I can’t boot with a intel 9400f after the bios update. Absolutely nothing happens then I try to boot. I’ve chosen the correct S-spec: SRF6M and the BIOS was flashed. I have also made the connection on the CPU pin. My original I3-6100 is still working fine. What can I do futher?

@mega_nix

The 9400F has 3 revisions - are you sure you inserted the correct microcode?

9400F U0 906EA
9400F P0 906EC
9400F R0 906ED

Have you checked the ME firmware version on the motherboard is correct? (11.6.x.xxxx or 11.7.0.1xxx)

Thanks for quick answer! Yes the S-spec is another way of seeing steeping.s-spec SRF6M = u0

How do I check my Me firmware version?

edit: Yes my firmware is version 11.6.xxx damn

@mega_nix

Try this BIOS based on 7.50;

z17p4s_mod_7.zip (7.6 MB)

I successfully flashed your BIOS, but it still doesn’t work.

Did you connect the SKTOCC pins so that the motherboard detects the CPU?

the 2 pins? Yes I used Electric paint for it

https://ibb.co/XSpTGrW like this.

The sticky mess on the other pins are tape for isolating.

@mega_nix Thanks for the image, you’re over to the left by 1 pad.

That should fix it.

haha… I’m sure I counted several times… smh

I will try, thanks I owe you!

edit: And it works!

@mega_nix Sweet, enjoy your new CPU!

BTW that BIOS has 5 micrcocodes with support for;

506E3 Skylake (6th Series)
906E9 Kaby Lake (7th Series)
906EA Coffee Lake (8 & 9 Series)
906EC Coffee Lake (8 & 9 Series)
906ED Coffee Lake (8 & 9 Series)

@revlaay I used the tool and must say I’m impressed with the result. The tool did NOT update the ME version (was 11.0) but that’s not a problem.

there is one thing you shoud change, though: currently the microcodes inserted are the ones you have chosen (the latest, although they are currently outdated).
I think it is a better option to give the user the option of different microcodes as the latest provide a performance drop up to 10/15% compared to pre meltdown/spectre mitigation.

Hello Guys,
I’m using ASRock Z270 Taichi, but Can’t boot after updating to mod bios.
I have i7 9700T (R0 stepping) and want to use it.

I have also made a pin mod on the 9700T.
And microcode 906ED is embedded in mod bios, and my original i5 7600K is working fine.
ME firmware version tried “11.7.0.1229” and “11.6.0.1126”, but neither will boot.

This motherboard has two BIOS chips, is this the cause?
Are there other ways I can improve?
