Gigabyte GTX 1080 Turbo OC Memory stuck at 405 Mhz after vbios update from official site!

Okay I updated my new graphic card with this:

https://www.gigabyte.com/Graphics-Card/GV-N1080TTOC-8GD#support-dl-bios

Result?

In Gpu-Z memory type is now unknown and memory clock is stuck at 405 Mhz. what can I do, tried all the vbios available on the internet for this card and nvflash keeps saying PCI mismatched!

Why would you upgrade the VBIOS in the first place? The issue seems to be an incorrect VBIOS flashed

You're right! Kinda a noob sorry, I thought it was the right thing to do with a new card

Updating a VBIOS is entirely unnecessary, there is no real reason to do so. Before trying what I prescribe next, try and delete/reinstall drivers with DDU. Next, I would try to make sure you have the right VBIOS, boot a USB with DOS and nvflash, and force flash it back.

Tried already with DDU, unsuccesfully, there's only one vbios available on GIgabyte site for my card, I'll try now with DOS

Should have saved the original BIOS.

Totally true, I'm such an idiot

Tried with DOS, nothing

So, I finally fixed my issue, I'll explain everything I did:

1) After flashing the VBios on gigabyte support page (link below)

https://www.gigabyte.com/Graphics-Card/GV-N1080TTOC-8GD#support-dl-bios

Using the utility integrated into the downloaded zip, the memory clock was stuck at 405 MHz, everything else was fine.

2) I searched for hours for a compatible VBios, nothing was working, the VBios that I flashed initally overwritten the PCI Subsystem ID, so nothing was working, nvflash was only giving me errors (PCI mismatch error)

Found only these VBios

https://www.techpowerup.com/vgabios/202799/202799 (I think this one is newer)

https://www.techpowerup.com/vgabios/203217/203217

The first one is the one from the official Gigabyte page (he broke my card essentially)

The others worked force flashing them using this command on cmd

cmd(as admin): nvflash64 -6 biosfile.rom

3) We skipped the PCI check and overwritten the existing one, and it worked! The card runs great and at its full potential!

Thanks everyone for the support, hopefully someone will find useful my experience!

Neh we knew all this before but we thought you knew it too.

I didn't, so probably other people out there don't know
