I've been told on the Homelab Discord server that the R730XD is too old to have Resizable BAR.
I'm interested in getting an Intel ARC GPU for transcoding but apparently it works best with Resizable BAR enabled. I looked though my copy of the R730XD manual but couldn't find anything about the setting, but that may be because it's a obscure setting?
Does the R730XD support Resizable BAR?
