I've flashed the latest BIOS and re-configured my overclocked settings. All works fine so far.
Do we know what Gigabyte has changed in the last 4 years of the BIOS?
f2g > f2n are many letters in between we don't know what they tried/changed :)

Thanks again @Lost_N_BIOS for the pit-stop like edit and upload :D
Cheers!

@vagdesign - You're welcome, and thanks for report back all is working OK! I didn't dig too deep, so not sure what all they've changed.
I did notice they updated two of the CPU microcodes since last mod I did for you (Last time I had to update x4, this BIOS I only updated x2 microcodes)

Was unable to test anything over the weekend. Now everything seems to be working well. Overclocks are stable too. Thanks a ton @Lost_N_BIOS

@vagdesign I wondered about the same because they jumped from g to n. Well every known issue in F1,F2e and F2g seems to have been fixed for sure. Played around a lot with the bios settings and ran tests all day. The only unusual thing i observed is a tiny performance hit (~ 0.5%) in Cinebench when using the bios with all enabled microcodes compared with the official F2n version. Not really a big deal. There's another tiny hit (~ 0.5%) between F2g and F2n so maybe it's two microcodes affecting Cinebench results each time lol

@animeanie - good everything is working well! And you're welcome

Hi!
What about Gigabyte GA-970A-UD3P rev. 2.0? Exist modded bios for this mobo, or work ok on rev. 1.0 update?

Hello @marcopolo7,
You can try and mod it yourself, it's easy if you read the steps and takes about 20mins total.
If you can't, ask from the forum members to help you out or maybe someone to have done it already!

I did it cause I know the motherboard is old enough and there won't be any "enthusiast" or modder to do it, so I decide to try myself.
You will feel better afterwards ;) Of course if @Lost_N_BIOS have time, can help out with unlocking "secrets" of your revision.

Good luck and when you do it, post it here and I will edit the title to include both revisions of our motherboard.

PS: If you're adventurous enough, try to flash my BIOS and in case it doesn't work, revert to the original (Motherboard have dual BIOS chip for safety).
Cheers.

VAG

This is not the motherboard model, the one we got it the GA-970A-UD3P and not the DS3P...
All manufacturers should try and name their products with a better way.

Hi, for my motherboard Gigabyte GA-970A-DS3 will work with this modified bios ? 970A-UD3P-F2g-Mod.zip or I should modify my bios with nvme module from this bios or I must to search compatible module. Thanks for help

Sorry @vagadesign - so I need to do mod for GA-970A-UD3P rev. 2.0 for @marcopolo7 then, correct?

@osiphos - no you cannot use any BIOS here, only one for your board. If your board is Rev 1.0 or 1.1 then your BIOS is not UEFI, so you can't insert NVME Module. If you have Rev. 3.0 board you have UEFI BIOS, and mod is below
@jayce - same as mentioned above

Here @All-Of-You
970A-UD3P Rev. 2.x NVME Mod - http://s000.tinyupload.com/index.php?fil...615991845137949
970A-DS3 Rev 3.0 NVME Mod - http://s000.tinyupload.com/index.php?fil...865774309917566

Flash using EFIFlash from DOS or Qflash
Once done, you need to do a clean operating system install, follow all steps exactly as mentioned in step #4 of this guide - [Guide] How to get full NVMe support for all Systems with an AMI UEFI BIOS

@vagdesign Hey I just realized why your nvme drive is running at reduced speeds. Check your inbox.

Do tell, if it works @animeanie @vagdesign - in case others run into similar issues

Hello @animeanie and thanks for the message :)
You mentioned the x16 and x4 speeds of PCIe lanes. This isn't the issue here. I've already placed it to the second GPU slot too.
The thing is that our motherboards have PCIe 2.0 technology and not 3.0.

Here is a list of differences borrowed from here: https://www.quora.com/What-is-difference...ess-3-0-and-2-0 and info provided by Mathew

- PCIE 3.0 supports a max speed of 8.0 GT/s (Giga Transfers per second) where as PCIE 2.0 supports a max speed of 5.0 GT/s
- The encoding used in PHY layer of PCIE 3.0 is 128B/130B encoding. But 8B/10B encoding is used in PCIE 2.0.
- PCIE 3.0 involves co-efficient based Dynamic Link Equalization phase during Link training process. But it is absent in PCIE 2.0.
- Compliance patterns are different for PCIE 3.0 and PCIE 2.0.
- PCIe 3.0 requires two tests for the Tx. The first is an electrical test that is similar to PCIe 2.0. Next is a preset test that verifies that the Tx de-emphasis and pre-shoot are within the limits for all Tx equalization settings or presets.
- There is an additional package loss test and couple for more Jitter tests(DDJ etc) for PCIE 3.0 compared to PCIE 2.0 during TX compliance testing.
- Receiver Jitter tolerance test is comparatively complicated for PCIE 3.0 compared to PCIE 2.0
- More Bandwidth Oscilloscopes are required for sampling PCIE 3.0 signals compared to PCIE 2.0.

So the drive I got performs around 60-70% of it's optimal performance.
I hope this helps ;)

EDIT: Here are the products I use on my build
Samsung MZ-V7E500BW 970 EVO https://www.amazon.de/gp/product/B07CGGP...0?ie=UTF8&psc=1
Aqua Computer Kryom. 2 EVO PCIe 3.0 x4 Adapter for M.2 NGFF PCIe Solid state https://www.amazon.de/gp/product/B0742LW...0?ie=UTF8&psc=1

There you go @Lost_N_BIOS, I think we can't do anything for this, cause it's hardware limitation and not a BIOS tweak :)
Cheers and thanks again!

Ah ok. I wrongly assumed you placed it in the smaller PCIe x1 slot judging from the shape of your adapter (original message), hence the reduced speeds.
And yes, the secondary GPU slot gives us the max transfer speed we can manage, even though it still limits your particular nvme drive. However I got the budget Intel 660p whose speeds are like half that of the Samsung (<=1800) and I think that's why I'm not seeing any bottlenecks
