I upgraded from Debian Bookworm (Stable), which has kernel 6.1, to Debian Trixie (Testing), which has kernel 6.4. Until then, I couldn’t overclock my GPU’s VRAM beyond 1750 MHz. With kernel 6.4, I can overclock it as far as AMD will allow - 1860 MHz. If my 5600 XT hadn’t been locked down by AMD, I’d be able to go further than 1820 MHZ on the GPU and 1860 on the VRAM.

    I used a program called CoreCtrl. I don’t think it’s in any distribution repositories, but you can install it from source, which doesn’t take too long. Though, you will need to add a special boot parameter to your GRUB file.

        So far, I’ve really only tested my VRAM overclock in the Nova: Covert Ops, but I’ve noticed that the cutscenes run a lot smoother. Before, there were a few that were a bit choppy, but now, they’re buttery-smooth!

        That’s interesting; kernel 6.4 enabled VRAM overclocking on my 5600 XT while disabling it on the 6900 XT.

        No problem! It’s kinda funny that you mention that it’s in Debian Sid. I was running Debian Bookworm when I installed CoreCtrl and I actually installed from source.
