@hancor
Thank you very much for the BIOS you provided. I have been following this post from last year, but I haven't been successful. I have tried so many ways, but sitll failed. In the end, I suspected that it was a problem with my adapter card, so I replaced it with a new one to solve the problem. In addition, I'd like to know whether the GA-Z87X-UD3H motherboard supports DDR3 3000 memory sticks? I'm using 1600 for now.

@Gmey

You'll find exactly three types of modules validated at 3000Mhz for this board; try the link below:

My son has been using this bios since the first iteration for about 5 years now; his memory is 2133.

You may have to do some searching on the memory...


Cheers

Hans

Edit April 30, 2020 updated network ROM/EFI and CPU microcode to version 28, further to this: corrected the double NVMe entry, now with single AMI NVMe EFI module


Okay went back a looked at the the original F11c bios posted by @Tigerfox and reworked the BIOS/UEFI and caught my error!

The re-edited version contains all the same modules, but now with only the AMI NVMe EFI module.

Try the reworked F11c

Minor network EFI update in the *.rar file. Last edit: May 7, 2020

Currently the official versions run from F7, F8, F9 and F10b

See here:

https://www.gigabyte.com/Motherboard/GA-...support-dl-bios

The latest beta bios F11c is found here:

https://www.tweaktownforum.com/forum/tec...atest-beta-bios

The modded F11c is based on the one found at Tweaktown's official Gigabyte BIOS collection which you will find in this thread.

I see no version F3, check your motherboard version and VERIFY it is for the same motherboard.

If it is the same motherboard I'd flash with F10b first and then follow up with the modded F11C as F3 seems rather dated...

Remove the CMOS battery from the motherboard, wait 60 seconds to let all the capacitors fully drain.
Reinstall the CMOS battery.
Restart the computer and check to load SETUP DEFAULTS

Edit: given the age, I'd also check if your CMOS battery needs replacing if necessary.

You can also use the CMOS jumper on your motherboard to CLEAR the CMOS see page 7 of your manual.

If the above works you can then load your custom/personal settings.

This is also a DUAL BIOS board so even if you mess up you can force it to use the back up chip.

The DUAL BIOS switch is located in the upper right hand of the motherboard, see page 7 of your manual.

BIOS Switch and BIOS LED Indicators is found on page 21 of your manual.

Support for DualBIOS™ as per the specifications page: https://www.gigabyte.com/Motherboard/GA-...3H-rev-1x/sp#sp

Motherboards that support DualBIOS have two BIOS onboard, a main BIOS and a backup BIOS. Normally, the
system works on the main BIOS. However, if the main BIOS is corrupted or damaged, the backup BIOS will
take over on the next system boot and copy the BIOS file to the main BIOS to ensure normal system operation.
For the sake of system safety, users cannot update the backup BIOS manually.

see page 89-91 of your manual

Hopefully that works, if not the very last stop is here:

[Guide] Using CH341A-based programmer to flash SPI EEPROM

Alternately, you can order a new bios chip via the interwebs fairly cheaply.

Guys...

I just try to update to F11C bios using @BIOS but system hang in windows10........ I have to reboot the PC...... of course BIOS corrupted.
it have dual bios supported but my CPU is 4790K.... I believe B Bios is NOT F9 +
so it cannot recover from B Bios...

so I have no choice to find a old processor to recover the main BIOS???

Please help :)

Thanks!!

Dear @MeatWar

Thanks for your reply!

I understand that I can recover from BIOS B
Actually Z87X-UD3H have a button to force it boot from Backup BIOS
The biggest problem is that I am using 4790K, It started to support on F9 only

Backup BIOS should be F6 only right??

Thanks :)

If all past updates, even before the failed F11, were made with the terrible option @Bios, the most likely the backup bios never was also updated.
The most reliable methods is primary Q-Flash (EFIFLASH as alternative), at certain point they also update backup bios version... now wots the version in there we dont know...but if ur
saying that the 4790K doesnt boot then ur probably rigth and its a lower version.
ALT + F10 should enable/force the flash of the backup bios.

Okay minor network updated as follows:



Microcode remains the same:

@hancor: It seems this Forum will be closing at the end of the year. Do you have any plans to continue your work, which is very much appreciated?

Thank you.
