Upgrade from 1070 to 4070 TI Super

[Kulisch]

Hello everyone,

 

despite the expensive prices from nvidia I decided to upgrade to a new gpu to open up more possibilities with AI.

 

I have therefore decided to say goodbye to my 1070 from Zotac and bought a ASUS TUF 4070 TI Super OC from Asus.

 

No other gpus are installed or iGPUs that I can use. (Ryzen 3800XT)

 

So that I could use Docker containers with my new GPU, I wanted to install the latest nvidia drivers. For some reason, however, there were problems downloading them and it kept giving me errors, despite rebooting the host system. So I removed the nvidia plugin, reinstalled it again, restarted unraid and successfully downloaded the latest drivers. Then I rebooted the system again and the Docker containers were able to work with the graphics card (if Docker Settings are correctly configured).

 

I also had difficulties with the VMs at the beginning.

 

In my setup where the 1070 was active I needed two things. Once a vbios file which I got from the TechPowerUp website and a user script that was executed when the array was started.

 

#!/bin/bash
echo 0 > /sys/class/vtconsole/vtcon0/bind
echo 0 > /sys/class/vtconsole/vtcon1/bind
echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbind

 

my vbios file: Zotac.GTX1070.8192.161103.rom

 

Both are apparently no longer necessary. 

 

The vbios file is no longer needed in the 4000 series, as I have read several times, because nvidia has apparently made some changes to make it easier for the user. 

 

If I understand correctly, the script has disconnected the GPU from the host system to make it "available" for the VMs. This was necessary with the 1070 so that I could use it there.

 

Even if both are no longer necessary, I still had a black screen when booting up. While browsing the forum I read that it is also possible to use the VNC interface as a graphics card in addition to the nvidia card.

 

Do not forget to configure the corresponding sound card from the nvidia graphics card.

 

 

I therefore created a Windows 10 VM and carried out the installation via the web interface.

 

I also installed the virtio drivers for the network interface (NetKVM) and the storage (viostor) from the virtio ISO.

 

 

 

 

And here the storage drivers:

 

 

 

After installing the OS, I created the offline account and finished the setup.

 

Then downloaded and installed the latest nvidia drivers. Normally it is possible to get graphics card drivers from Windows Updates but in my case none were offered for download.

 

The physical display output appeared after the installation process.

 

 

 

Just to make sure that this is not only temporary, I restarted the system via the OS. Then shut it down and booted it up again... and it stayed that way.

 

However, I noticed that the BIOS is only visible in the VNC. On the physical screen, the display output only appears when the OS and the corresponding graphics drivers are loaded.

 

 

 

After making sure that this works for the most part, I removed the VNC graphics card. The nvidia card remains in the configuration.

 

 

Started again and after a few seconds the Windows desktop appeared in the physical monitor when the OS is fully booted.

 

How exactly I solve the problem to get a permanent display output to see the BIOS or when updates are running or a hard disk check is performed,.. I can not say at the moment.

 

If anyone has similar experiences or even a solution to this problem, I would be very grateful if you could let me know.

 

I hope I could help some of you with this information.
