Hey,

iam building a libreboot workstation and would like to check if the gtx 750 ti works with linux-libre and bouveau.

Has anyone experience with this card and can confirm that it works good?

Some models have displayport 1.2 connections and it would be awesome if i could use this with a 4k display on 60hz with nouveau but i dont know if this works or how good the displayport connection from nouveau is.

I have GTX 750 ti with hdmi, dvi and vga outputs and it works fine with Trisquel 10 and Nouveau. I'm not running it currently though. If I remember correctly it wasn't quite fast (with Tuxcart no max settings). I had two monitors on and desktop was smoooth. Hope this helps.

This was probably because the card was running at a low frequency. The card will not change frequency based on demand. It is possible to change the frequency though. To do so run the following:

sudo cat /sys/kernel/debug/dri/0/pstate

You should see something like the below:

07: core 405 MHz memory 810 MHz
0f: core 270-1241 MHz memory 5400 MHz
AC: core 405 MHz memory 810 MHz

For playing games, change the clock with the following command:

echo 0f | sudo tee /sys/kernel/debug/dri/0/pstate

The screen will likely flicker. You can confirm the setting was changed by running the "cat" command again. The following will be the output:

07: core 405 MHz memory 810 MHz
0f: core 270-1241 MHz memory 5400 MHz AC DC *
AC: core 1012 MHz memory 5400 MHz

The "*" indicates which state is selected. Also, notice that the frequency listed for "AC" has changed.

Then, when finished playing, change it back with the following command:

echo 07 | sudo tee /sys/kernel/debug/dri/0/pstate

I don't have a 750 Ti but I do have a GTX 760 and a GTX 780 Ti and both work on Trisquel 10 through Displayport for me so I would expect a 750 Ti to as well. I use them on a 1080P 144Hz screen.

Of course GTX 760 and 780 would work - they're both Kepler. But 750 is Maxwell architecture. Maxwell might have some trouble with Nouveau, if I remember correctly.

Yes as far as i know has the maxwell gen 2 architecture no good support but gtx 750 (ti) is gen 1.
Tomorrow i will get my gtx 750 ti and then we will know some more :)
