I understand reclocking on Nouveau is very experimental still, but I figured I might as well send in this bug report anyway.
On my NVCE (GTX 560 from EVGA), the standard (boot) clock speeds are 50 MHz core, 100 MHz shader, and 135 MHz memory. Naturally because of this, OpenGL performance is terrible (possibly worse than older Intel chips like the 4500HD), about 15-20 FPS in Red Eclipse and about 5 FPS in Xonotic.
I am able to reclock the card, however, upon doing so, it comes up with this error in dmesg:
[11245.600378] nouveau E[ DRM] cannot reclock unsupported memtype
So, I'm able to get the GPU core and shader to run at their highest speeds (850 MHz and 1701 MHz respectively), but the memory speed stays at 135 MHz (when it should be at 2052 MHz). Even though I can change the clock speeds, after a while, the card will crash, forcing me to have to reboot.
I'm also uploading things such as my lspci_output, nvce_strap_peek, nvce_timing_peek, nvce_bios.rom, and nvce_vbios_parsed, so it'll hopefully help you guys out on getting things working.
