The 1gb nic on this board works fine. Never tried to pass it through.

i dont  have the included Aquantia Pcie board so I couldn’t tell you.

using 6.7.

Im embarrassed to say that a large chunk of problems disappeared with a cmos clear, probably had bad ram training. Freezes and crashes have cleared up. Also , strangely , turning memory interleaving back to auto DOUBLED my applixation Performance (remember I’ve got my vms pinned to one ccx each).

System works very  nicely now. Would still like to figure out how to pas through the 3.1 usb controller (VM won’t boot , “not a passthrough device ”) and the. Asmedia usb controller (perpetually needs a reboot to enable passthrough).
