I have the same motherboard and have just purchased a nvme and a PCI card. I delighted to have stumbled upon this post! I will attempt this tonight and let you know how I get on! Is there any tricks to updating the bios? This will be the first time I have done it.
Thanks!
@Jamtil - Put BIOS on FAT32 formatted USB Stick, boot to BIOS and hit F8 to enter Qflash, navigate to BIOS and flash it 
Then see step #4 of the “This is what you should do” section for how to do a clean install to NVME - [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS
@Lost_N_BIOS Thanks! I’m getting an error that my qflash is outdated. I can’t even get the oldest gigabyte one to flash. What’s the best work around for this?
Update… managed to install with dos on a mem stick, amazing how much faster this is! Thanks to your 1.0 bios!!
@Jamtil - This happens when you are on old BIOS and the new one contains a newer Qflash module.
Sorry, I didn’t expect you were on that old of a BIOS, or I would have told you that you need to update to latest BIOS with DOS first (or @BIOS), then Qflash the BIOS I made.
Glad you figured it out, and thank for posting back in case it helps someone later Also, great to hear new BIOS is working much better for you 
@ Lost _N_Bios, None of the links are valid.
Could you upload it again & give us the new link.
thank you in advance

@Lost_N_Bios: I’ve already succeed in downloading it via tinyurl.
thank you.
@Zhuge_Liang - Who browses the internet without ad-blockers enabled these days? Tinyupload does not have any ads when I am there, it’s best free file host I know, easy to up/down from, no waits, and keeps files alive the longest.
If you know of another similar free site, please let me know.
BIOS link at post #9 is valid, tinyupload link.
@ ALL >> Rev 1.0 & 1.1 use exact same BIOS, I just compared F20 via hex = 100% hex match, despite the different zip package download names.
Hey,
I´m Kinda Love to your Idea and Awesome that there Guys who build an Custom Bios for that
did you also run your OS on that PCI NVME ?
or is it "just" an additional Drive?
Best regards
Nerdbeere
@Nerdbeere - Users here want NVME mod so they can boot their OS from NVME. If you just want to use NVME as spare/secondary non-OS drive, you do not need NVME mod
thank you to Lost_N_BIOS, I’ve succesfully updated BIOS and my Samsung 970EVO has recognized as PATA.
But unfortunately when I installed windows 10 Pro:
although Win10Pro recognize the NVME, but Windows stated that windows couldn’t be installed on that drive.
Hi @Lost_N_BIOS , tried the link in post #9 but it seeems to be dead. Would you be so kind in reupping the file? Thanks!
@Zhuge_Liang - You need to follow step #4 in the “This is what you should do” section of this guide
[Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS
USB w/ install media on it should be initialized as GPT, best to use Microsoft USB/DVD tool to make your install USB
And NVME should be RAW (best) or Initialized as GPT. Here’s how to make RAW - You can use diskpart in windows from OS (Direct from any CMD Prompt), or from installer ISO (press Shift + F10 on the first setup screen where you pick language)
Or from repair/troubleshoot options in the installer/setup. Remove all other drives, so you have only USB and target win10 drive. Then from CMD prompt do the following
1. Diskpart
2. List Disk << Here, identify what your target disk is by size/name etc, and make note of it’s #, you will use it’s # next - (If in windows, these #'s will match what you see the drives shown as in Disk Management) - Be sure you do not select your USB or main OS drive if in OS
3. select disk # << Here, instead of #, put target disk #, example >> select disk 0
4. clean
5. Exit
Reboot and run the installer again, then point it at the raw/blank drive, do not load any drivers or create any partitions etc, just select drive and click next
@Crinson - Thanks! Yes, sadly, it looks like Tinyupload may be dead (down for nearly two weeks now 
)

Thanks @Lost_N_BIOS you saved my rig, It’s working flawlessly. Booting from NVME is at least 40% faster than with my previous 8 year old SSD 
Great to here all is working smoothly @Lost_n_bios: thank you for guidance. when you haven’t replied yet, I’ve succeed in installing windows to SSD (non NVME) by setting the boot sequence to UEFI DVD-ROM Drive, not legacy DVD-ROM Drive as before. Then I cloned the non-NVME SSD to NVME
After set boot sequence to NVME, the NVME could do UEFI booting.
BTW next time I’ll try your suggestion.
thank you
@Zhuge_Liang - I replied above Thanks for your posted info though, I assume most use USB to install, so had not considered if you used DVD that you need to choose UEFI DVD not legacy, thanks for pointing that out it may help others who use DVD
Hi @StormRaider
I am new here and I do not know much about modding.
Can you tell me do you use asus hyper m.2 V2 card on your gigabyte x79-ud3 motherboard? I would like to know if it works. Because in my case when the hyper m.2 V2 is with/without nvme ssd on it is installed on motherboard, I turn on pc but before post it crash and never boots only crashing. I put asus hyper card in different pci express slots but it do the same. Pci lanes should be enough. I try with this modded bios but no different. I have no idea what to do. Is it possible that need to be added bifurication in bios?
The asus hyper m.2 V2 is working, I test it on other pc.
Lost_N_BIOS is been away since the beginning of the year, do the mod yourself, address it to a specific user in this thread still active that can share it.
U can use MMTool method and Q-Flash.

I installed the mod bios (from Gantrithor) to my GA-X79-UD3. I also got the boot failure detected as my board is Ver 1.0. I already had my EVO970 plus installed and working just not booting. I disconnected all my drives and successfully installed win 10 on the EVO but IMEI would not install properly in windows showing a yellow warning on PCI communications device. it did not boot that fast (my ssd was faster) even though aida64 showed read speeds at 2,500 +
I plugged in my previous drives and booted back into my intel UEFI RAID GPT dual boot 2 partition SSD with Win 10 and Win 7, along with 4 more drives, 2 on intel raid 1 and 2 on marvell raid 0. All raids working properly but in win 10 it has a error with IMEI cannot start. Win 7 has the same error. Both booted up slowly.
I put the old bios, F20, back in and tried it again one more time making sure there was no presence of my raids. Boot failure detected once again and same problem booting to the Win 10 NVME, IME interface was the issue again. I did not try booting into or hooking up my old SSD.
I reinstalled the F20 bios once again, hooked up my SSD and my raid drives, setting the bios accordingly and booted into Win 7 with no issues, I even have a NVME driver for win 7 and runs at 2500 + and left it installed. I rebooted the computer and tried booting into win 10 and got a BSOD (kmode exception not handled) rebooted and tried a startup repair recovery and BSOD. Rebooted again and tried all other repairs including booting into safe mode (BSOD) and no go. It will not even boot up on a UEFI USB without the same BSOD. Boots into WIN 7 no problem except for some chkdsk’s had to run first.
It seems that the UEFI boot to any win 10 device will not work but no problem into UEFI Win 7 on same SSD. I also tried a legacy boot to a win 10 USB and it will let me go froward right to the advanced setup screen but will not allow me to install to the old win 10 install as it is a GPT disk.
I did a memtest86 and it had several errors. Reinserted it and same thing. Took it out and installed other memory and no errors, so I thought the memory was the problem. Put the “bad” memory in another machine and ran memtest86 and no problems found. Board with new memory still has the BSOD going into any UEFI Win 10 including trying a win 10 install from a UEFI DVD player.
After all BSOD’s it usually has to run a chkdsk when going into Win 7, other then that Win 7 works perfect other then a IRST verify on my Intel raid1 once.
I have been going nuts trying to figure this out, I even did a dual bios recovery (went to F16) and still no luck. Win 7 is my main operating system and has been for ages as Win 10 will not run a PC anywhere host. I need win 7. As far as I can tell there must be a problem with the Roms in the bios (UEFI RAID, UEFI AHCI, IRST, IME??) but I just don’t know how to fix it. it would have been great to boot with my NVME, I even had a boot USB made up with Win 7 NVME drivers that I almost had working when the mod bios was in. I could not find lost_n_bios 1.0 mod version.
If there is anybody that can help with my issue it would be great, I have built at least 10 computers in my life and troubleshooted many more but Im in a little over my head with the bios mods.
