Generally USB Flashback is not like "playing game", if you don't know how to do it.
First of all which bios you were trying to flash via flashback? from which post? number?
Your bios needs .CAP bios files as you already have 4701 version.
Or maybe .ROM if you didnt change it.
You will have to answer us if your bios takes .ROM or .CAP files, but i believe it takes .CAP files.
The bellow is for .CAP only.
If you have .ROM just swap .CAP with .ROM.
To flash bios (.CAP) file you need USB 2.0 formated as fat32 and not above 2gb.
So lets take it from the beginning:
1)Take the bios you want from the post you are interesting in.
2)Rename that bios to "SABERX79.CAP", and NOT "SABERX79.CAP.CAP", Please select in windows to show file extensions.
3)Clean everything from usb pendrive.
4)Copy SABERX79.CAP file into your's usb2.0 pendrive.
5)Turn OFF your pc.
6)Take this usb from any port you had it and insert it in white usb port(down from the flashback button).
7)Just press the flashback button for 5 sec and wait the proccess to start.
8)Wait until it stop blinking and thats it.

If that doesnt work then disconnect your cpu, ram, gpu from motherboard and repeat the above steps (only steps 7 and 8).
(Please if you dont know how to disconnect the above dont do it alone, unless you will harm your pc).
Let me know if your problem solved.

0) Are you sure you updated the BIOS (only BIOS Flashback works, but remember - it will start with slow blinking, and will keep getting faster until it's done). If it starts, but never does faster part - you failed at updating. Also, did you used FAT32 USB storage for updated file ?
1) Is NVMe it formatted as GPT ?
2) Are you installing Windows in UEFI mode (CSM must be set to UEFI first on USB/Boot devices)
3) Did you cloned AHCI/SATA drive ?

Unplug ALL other hard drives and SSDs (other than that NVMe), and then install Windows on NVMe (remember to boot it in "(U)EFI"mode). When that's done, you should get standard options in Windows installer (along with GPT and booting partition (assuming you didn't partition the driver earlier).

If I format that drive in windows before installation (clean install from a USB installation drive) I get this error:
"Windows cannot be installed to this disk. The selected disk is of the GPT partition style.

Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu."

If I delete the partition I get this error:

"Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu"

So I'm unsure if A) I missed some important settings in BIOS B) I didn't flash the BIOS properly.
Is the BIOS info I provided correct?

Make your USB GPT then put install media on it. Then install to RAW disk and let windows set it up

I'll try that, but would you be able to confirm that those numbers I provided (BIOS build data, versions ) are correct? I've been trying to figure this out for the last two days by my self and I'm starting to think I must be missing something really simple here.

Well ... I'll be damned ... this worked!! I would have never thought that I need to set a different format for the install USB drive. Thanks!

@kindalost - None of that matters, if you are using some NVME Mod BIOS from here, only linking to that post or giving the post # will help us to tell you if BIOS is OK to use or not. I think I removed all buggy ones for 4701
Here is latest with bifrucation mod and all updates tested and all good now #173 - [OFFER] ASUS Sabertooth X79 4801 beta BIOS (compl. updated incl. NVMe support [v4]) (12)
And here is one with microcode and NVME mod only #147 - [OFFER] ASUS Sabertooth X79 4801 beta BIOS (compl. updated incl. NVMe support [v4]) (10)

* Ahh, you got it, nice! You were replying while I gathered the above reply/info for you
Yes, you have to install from GPT >> To >> GPT or RAW

@Lost_N_BIOS - Downloaded the BIOS from #173 a few days ago but wasn't able to update until now... Everything seems fine now, no performance penalties ;). Once again a big THANK YOU to you and all involved.

@chi - great to hear it, and thank you for the quick testing report You're welcome!!

hey Guys, got some trouble with using my new Samsung Pro970. PCIe Adapter: https://www.amazon.de/dp/B07RZZ3TJG?ref_..._302_E_DDE_dt_1
sticks like in every other case in second PCIe x16 slot. Installed today nearly every Bios version that has been posted in this thread and
Configured bios in CSM/SATA and everything that has been promoted.

It's still not shown as bootable option or something and i dont know what i can do else. The leds on M2-ssd blink up once if bios gets loaded up. Thats the only sign i get to realize it gets somehow electrical signal.
Otherwise i removed external Sound-card and disconnected every normal SATA-port to refuse that any ports are parallel wired and disconnecting each other while engine.
Bios updated worked also, Bios Versions changed, (tried those A/B/C bios-setups (D is open, since not released yet)) the only point that did not show up was under "advanced options" -> Guess that there should be created NvmE Options/support or something, thought i have seen an image of someone but didn't find now as prove.


I hope that i just forgot any point. Thanks for reading.
#edit i think i just bought false adapter, going for new one..

NVMe will be shown IF you have bootable files on it.
I suggest trying Windows installation under (U)EFI mode to see if NVMe is detected.

Alternatively, you can use current Windows installation to check if NVMe drive is visible (it should be if adapter works, and that's regardless of used BIOS be it moded or official one).

@Daserste1 - Have you setup and used NVME Before? If not, you need to do things in certain way before you will see it in BIOS. Please follow all steps at #4 in the "This is what you should do section" here - [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS
On your USB install, make that GPT and then create your partition and put install media on there. You have to install from GPT to GPT or RAW disk (or let windows do it for you)

Adapter is probably fine! Unless you bought one of those dual ones with SATA cable attachment, if you have one of those make sure you have it on the slot that does not connect to SATA cable (because that one will not send data though PCIE Slot)
This is one I use, cheapest I could find - https://www.amazon.com/gp/product/B07GPBBCGS

@Daserste1 Which Windows are you trying to install on it ?
(10 / 8[.1] / 7, x86/x64, etc.)

Hello all,

Well I did as much hunting as i could for a USB 2.0 stick. I went to my local junkie computer store (sells older stuff) and they had a kodak 16gb USB 2.0 pen drive (EKMMD16GK7602) it was the only one they had and well, no dice. The same old blinkie blinkie, solid blue.
At that point I gave up, wasn't going to keep hunting and spending money on more USB 2.0 sticks so I bit the bullet and did a platform upgrade, 9600k :)

To be honest, I was riding on sheer luck since my sabertooth x79 has been through so much. Sustaining high OC of 4.8ghz on my 3930k on water, mining, tons of gaming and 2 years ago my 980Ti caught on fire at the PCIE BUS! the motherboard survived! But for how long? well..2 days ago haha.
I was having trouble getting into the BIOS a few times, hitting DEL at post, hearing the beep, seeing the splash screen but then as it tried to enter the BIOS, black screen. It took several battery pulls and full power drains plus cmos clear pin to get into the BIOS sometimes...so perhaps the flashback with the 3.0 stick was only a small contributor to my brick.

I want to thank all of you for responding so quick to my posts and offering all of your support. This is a great community with very supportive tech nerds :)

Take care.
