The Nvidia Settings utility shows PCIe link data - width and speed. Is there any way to get control over the way the PCIe link is (dynamically) configured?
nvidia-smi --query has even more output (see below) and on there, I’d really love to try setting
- PCIe Generation = 4
- Link Width = 16x
(I do not know whether GPU memory clock and PCIe configuration are tightly coupled; basically, I simply want to have the “pipeline” == PCIe open as much as possible, because I can afford this, on this notebook)
