Everything is showing up correctly in Hwinfo64 for my Z170 SOC Force board after downgrading the bios.
I have a RealTek 8168 NIC do you or anyone know if the mac address is overwritten with FPT flash tool? Because there is not a BIOS procedure for for RealTek NIC.

Because the hex editor for the MAC inserted into the bios file you want to downgrade to will NOT work with network chips of ANY other brand, i.e. Marvell, Atheros, Realtek, Via, Broadcom! Check your mainboard's specifications before trying the following: https://forums.tweaktown.com/gigabyte/53618-x79-intel-gbit-lan-gbe-firmware-update-howto-socket-1155-1150-a.html

No it will not overwrite your mac address as you do not have an Intel NIC, so you do not have to worry about manually editing your mac address.
Just run the FPT tool and downgrade your bios.

It's in your owners manual. On my board, which has two switches - one for main/backup (BIOS-SW), and one for dual/single (SB), you switch the BIOS-SW switch from position 1 (main BIOS) to position 2 (backup BIOS).

I would highly suggest maintaining the MAC address the board came with, especially if you're running online activated software such as Windows or Adobe Photoshop since a different MAC address could affect activated software, if not now, perhaps down the line. I'd also advise double checking Windows is still activated after "downgrading"; especially if you did overwrite the MAC address.

Just something to think about and be aware of.

My two cents.

Are you sure FPT flash tool wont overwrite the MAC or motherboard S/N? I did this before with a Z68 and I had to reactivate my OEM windows, I did not know what happened.

Do you have the Retail copy of windows or OEM?


From what I have been reading the FPT tool flashes the hole Bios, the Gigabyte's BIOS flashers don't overwrite the entire flash ROM.

I think my Z170 HD3 is overclocking OK with F21 just that CPU-Z and HWmonitor take a long time to load. What problems have you found?

Windows 10 Activation does not work off the NIC Mac Address, nor the serial number of the board. It works off the actual board chipsets, because I have moved my Win 10 drive from an Asus Z170, to a Gigabyte Z170, to an Asrock Z170 board and all of them had the same chipset and same Intel I219-V NIC and my Windows 10 remained activated at all times and did not need reactivating whatsoever.

I am running a retail copy of Windows 10 Pro.

Yes the Gigabyte Bios updates do not overwrite the NIC Mac Address, but the FPT tool does when you are running an Intel Gbit NIC. It does not effect activation, nor does it effect the operation of the NIC. Everything networks properly, except you just have a non conforming MAC Address format.

The F20d bios for the SOC Force, has a few issues both at stock AUTO settings and also when overclocking memory. At AUTO settings it runs a lot higher vcore voltage by default, which can be overriden by manually using a Fixed voltage. However, when overclocking memory, especially at tight timings such as C12, it will not run above 3200mhz, regardless if you manually set the frequency higher in the bios. When training the memory it overrides what you have set and sets it at 3200mhz. There was no way around this and as I use the board for overclocking/benching this was unacceptable and I downgraded.

The above was with my 6700K cpu. When I downgraded back to the older style bios, everything returned to normal and overclocking memory at 3866 or higher at C12 was not a problem and passed training everytime.

With a retail copy of Windows 10 Pro you can transfer to any PC and don't have to activate it is automatic. The Chipset has nothing to do with information in the BIOS chip. Windows uses the BIOS for verification, I have OEM windows 10 that has to have the same board S/N in BIOS.

The Chip set is the South Bridge, the is no information passing from it. The chip set is a integrated circuit that manages the data flow between the processor, and peripherals. .

How do you know that FPT tool does not overwrite the RealTek MAC? I can't find information on that only Intel overwrite.

Because the readme file that comes with the FPT Tool, clearly states that if you have an Intel NIC then it will change the mac address and you have to edit the bios with a hex editior to adjust it to your mac address. Since it does not mention any other brand NIC's then it will not overwrite the Realtek NIC's mac address.

It stands to reason that if other brand NIC's were affected, then they would also be listed in the FPT Tool readme file.

As for Windows activation, it is linked to the board, which includes the board's chipset, and if the chipset is completely different such as going from Z170 to X99 for example, then it would require to be reactivated, regardless of whether it is a retail Windows version or not.

If it were tied to the board's bios, then I would not have been able to change from one brand Z170 board to another, without requiring activation, as every Z170 brand board I have has a completely different bios. This was definitely not the case, as I moved my Windows OS drive to different Z170 boards and no reactivation was required whatsoever.

Windows creates an activation identifier key based on the boards hardware, including chipset, nic, cpu type etc and if the hardware changes from those specs, then Windows thinks it has been moved to another system and requires reactivation. But if all the boards features are identical, so same chipset, same model nic, etc, then Windows thinks its the same hardware and does not reactivate.

Changing your NIC's mac address has no bearing on Windows activation at all.

6700k | GA-Z170N-Gaming 5 | Samsung 950 Pro | Windows 7 Home Premium

With those specs in mind here's what I've done. Upgraded from F4 to F22. Biggest mistake ever. I tried downgrading with the ftp tool and have followed the exact instructions posted on multiple forums (same as in the ftp .txt file) to no avail. When I boot from the USB it doesn't automatically downgrade me, it jumps to the default bios screen and does nothing. If I enter q-flash, I can point to the renamed BIOS file (bios.bin) but If i try to upgrade from there I get the error that I need to upgrade to the latest BIOS file.

Also as a side note, everything is so fubar that i can't register any drives in the windows environment (I'm amazed I could even get into windows). But that means I can't utilize any tools from within windows because i can't pass anything via USB i.e a utility or my wireless driver.

I posted a number of other areas including on TweakTown Forums Gigabyte Latest Beta BIOS page as well, I hope someone out there can help me, so far no responses, so no solution.

I too am having many issues with the F22 bios on my Gaming 6. I was on the F3 that is shipped with and should of never upgraded. My auto voltage does not get me to 4.4 stable, seems to be not pulling as high with a max of 1.265. I know I can manual OC, but I like the auto to down-clock. I have not tried off-set voltage yet. I also am not able to get some OC settings to save. Took me forever to get the ram to run at 3200 mhz. Also, when I up the multiplier to x 44 to oc, I am suck at 43.

I know on the support site it says that you can not downgrade past F20, however I would like to see if just normal flash will take me back to F3?

You have not gone to the link in the readme file, it clearly states OP Bios edit won't work on RealTek.

Windows OEM is tied to the same motherboard even if you change the motherboard with the exact same one you will have to call into Microsoft. You have Retail copy of windows, activation with Microsot does not apply when switching motherboards.

Where do you think the information is kept for the Chipset and everything on the motherboard?
