@iJoshh - What operating system are you using, and what drivers? That kind of info may help someone like @Fernando offer some advice on this issue.
You also may be better off with the now more commonly used NvmExpressDxe_4.ffs file instead of v3

Also, just my personal opinion, I hate BIOS 4801 variant on any Asus X79 board, it always caused instabilities for me (Unrelated to your mentioned issues, but that could be causing some of what you're experiencing too)
If you want, I can update 4701 for you with latest microcodes and NvmExpressDxe_4.ffs for you to try out? And you also may need to use a better driver for best performance, but I can't comment on that as to which is better.

Hi,
After unsuccessful trials of booting with clover with usb and booting with my new nvme disk, I found this thread and it worked out smoothly.
Anyone having Asus sabertooth X79 mainboard can use it without doubt.
Thanks a lot.

I picked up a Samsung 970 Pro with a m.2 to pci-e 4x card. Flashed the modded bios, used the Samsung Transfer tool to transfer my data and was able to boot off the nvme SSD with no problem.

I'm able to get full read and write speeds as if it was connected directly to a m.2 port on the motherboard.

Thanks for letting me breath some new life into this PC!

I have issues with 4801 as well... As already stated on another forum, the power consumption of my X79 is lower after a cold boot and I'm having all sorts of micro-stutters (GPU + LAN). It all went away after I reverted back to 4701 ;). So if you could update 4701 with the latest microcodes and MVMe, I'd give it a try... THX

cheers, chi

Agreed @chi - all X79 boards with 4801 BIOS (or whatever # adds the new 128MB memory thing), it's a bad BIOS update series I've found, I tested several different X79 models with 4801, all I didn't like how the board ran and went back to next BIOS down.
Which exact board model do you want update microcodes and NVME into 4701 on? Please link, thanks! I would assume Sabertooth, but you know how assumptions go...

Yes, I have an ASUS Sabertooth X79. Thanks in advance

@chi - Original BIOS has 4 microcode volumes with 2x in first two and 5x in second two (14 total), update I made all same (5x in each = 20)
Flash via USB Flashback and do not rename the file, in case you didn't already know this for mod BIOS.

@Lost_N_BIOS I just flashed my board with your updated BIOS, but unfortunately it didn't work... After a flash (when I press the power button) it usually starts and immediately (2-3 sec) shuts down again, followed by a restart where I can go into the BIOS menu. But with your BIOS mod it just hangs after the power button was pressed... Any ideas why?

@chi - sorry about that, there could be a few reasons causing that, lets try this method instead. If this fails in a similar way, then I know we need to leave those old 2x entries alone with their two old microcodes.
I thought it was odd to have 4 microcode modules in there with two only containing two old codes and then other two updated, but first lets see if this works, then if not I will leave those in there.

@Lost_N_BIOS Apparently this update works as expected... This time it didn't hang after the flash and I was able to go into the BIOS menu after the self-initiated restart.

Thank you very much for your efforts! Much appreciated

Does this contain the NvmExpressDxe_4.ffs driver?

Thanks

@chi - great that one worked, happy to not stress you out again

@mafiaboy01 - yes, that contains updated all CPU microcodes to latest version and NVME 4 mod

Awesome! Running great here with my 970 Pro getting full speeds.

@iJoshh This might be unstable configuration... is SMART reading of ALL disks connected to your PC "OK" ?

Works here, ok.
