--- Comment #6 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Does this card seriously have 6GB of dedicated GDDR5 VRAM? Or is it
misdetected? (Hm, looks like indeed one of the options on the marketing
page...)

I would not be surprised if we had some bugs for cards with > 4GB.
Unfortunately we don't have a vram_limit parameter.

Could you edit drivers/gpu/drm/nouveau/core/subdev/fb/ramnvc0.c -- take a look
at nvc0_ram_create_, and after the for loop that does ram->size += xyz, just do

ram->size /= 2;

which will bring it down to 3GB... No clue if it'll help, but worth a shot.
