NVIDIA 바이너리 드라이버에서는 GPU가 사용할 수 있는 시스템 RAM의 양을 지정할 수 없습니다. 나도 nouveau
이것이 허용된다는 말을 들어본 적이 없다 .
NVIDIA 드라이버의 최신 안정 버전에 대한 옵션은 다음과 같습니다.

NVreg_MemoryPoolSize는 흥미로워 보이지만 필요한 것은 아닙니다.
* Option: MemoryPoolSize
*
* Description:
*
* When set to a non-zero value, this option specifies the size of the
* memory pool, given as a multiple of 1 GB, created on VMware ESXi to
* satisfy any system memory allocations requested by the NVIDIA kernel
* module.
그냥 재미로 다음과 같이 시도해 보겠습니다.
/etc/modprobe.d/nvidia.conf
options nvidia NVreg_MemoryPoolSize=4
