No it won't, you are better off making your own modified BIOS using Revlaay's tool or CoffeeTime.

Hey, you think it can be done this way (Q-Flash method) on all gigabyte mobos? In my case Z170X-DESIGNARE

Yes it is possible, however it is much easier to just use the modified version of EFIFlash.

Hi chinobino, thank you for posting the Bioses and info. But I'm confused if my I3-9100F, ist supported by your F20 or F21f.
Your quote of shixinyuan lists the 9100F twice, once as 906EB,B0, and once as 906EA,U0. So now I'm confused which one is correct, or if there are 2 different revisions.
I already isolated my cpu pads according to your graphic with nail-polish, but with both, F20 and F21f I couldn't successfully boot with the CPU.
Now I'm wondering if it's because of the not supported i3-9100f or because my CPU-pad isolation wasn't perfect.
Also I asked myself, when I compare your graphic for the CPU-Pads, it differs from from some images of coffee time mod i found on the web, but since you already had them working I trusted your instruction.
But now I just came across an Info which states, "for revision B0 processors, a pinmod is not required" Is that true and is i3-9100f one of these B0 CPUs?
If I already did the mod, does it work with and without the pinmod, or should I undo the mod?
I hope you can help me out, of nicest of all in case if a different biosupdate, would it be possible to provide it for me? If not, I of course understand, but I'd be happy if you could answer my other questions if possible.
Thanks!

@feilsch_hering Hi, as you noticed there are two 9100F CPUs.

The first (906EB) B0 revision has an S-spec of SRF7W (check your CPU box stickers or CPU heatsink) and is a true quad core die, which means it doesn't need pin isolation or the SKTOCC mod.

The second (906EA) U0 revision has an S-spec of SRF6N and is a hexacore die that failed validation and so 2 cores were disabled, if you have one of these you need to do the pin isolation and possibly the SKTOCC mod, depending on which motherboard you have (many Gigabyte and MSI motherboards do not require it).

Neither of the BIOS I uploaded have support for 906EB, which might be the reason you can't get the CPU to post.

Svarmod made a BIOS with 906EB support which I will link to below, you will need to flash with EFIFlash;

Motherboard: Gigabyte Z170-HD3-DDR3
Based on: F21f
ME: 11.6.0.1126
Microcodes: 506E3, 906E9, 906EA, 906EB
Tested with: G3900, i5-8600k by @svarmod
Note: For 6-core CPU need isolate/remove RSVD pins in socket, like image below, to prevent damage mb.
OC from bios for unlocked 6-core cpus works correct.

Thank you for clearing up the 9100f confusion for me, I do have the SRF7W version (906EB) B0 of the i3 9100f.
I just had some trouble flashing with efiflash until I found your modded version, then flashing worked fine.
The CFL_MOD_Z170HD33 Bios works for me, thank you for providing it!
I might remove the insulation, but it seems to work like that as well, if there is no downside leaving it on I might leave it.

Do you know if Bios feature special overclocking abilities, like unlocking, or raising the FSB is the way to go?

@feilsch_hering Overclocking non-k Coffee Lake CPUs is limited to ~102 MHz base clock or slightly higher so you *might* be able to gain ~100 MHz at best.

Absolutely fantastic job. I have a request, could you please mod Gigabyte GA-Z170X-Ultra Gaming bios mod for Coffe lake ?

@ticed If you don't feel confident doing it yourself you should start a new thread requesting the BIOS mod for that motherboard so that others with that board can benefit. No-one will find it here ;)

Will it work with engineering sample cpu ?

@xshg1 Which ES CPU specifically?

i7 QN8G "8700k"

#28 RE: [OFFER] Gigabyte Z170-HD3-DDR3 BIOS with Coffee Lake support (BIOS F20 906EC) (BIOS F21F 906EA, 906EC, 906ED) by chinobino 28.05.2020 07:02

@xshg @xshg1 Yes, that CPU requires the microcode for CPUID 906EA, so you can either use my BIOS in the third post OR Svarmod's BIOS linked above.

Note that you can flash mine with Q-flash but Svarmod's requires you to use EFIFlash with DOS on a bootable USB.

ok thanks for the info

@chinobino hay im relatively new to this mods concept i have gigabyte z170 hd3p motherborad on i7 6700 cpu and the latest official bios update ...soo.
1.can i9 9900k work on my motherboard without any failure's like the pci express and exc.?
2.should i mod the processor like you did with the red nails colors (can you send my a video link )
3.should i need only to run bios update 21 & 22 ?am i missing other thing
4.could i overclock it on the end?
