Added a 1660Ti to my server (Plex transcoding/Folding@Home). Working a treat.

My cpaine riser arrived today, I'm using a PCIe extension cable from ADT-Link, all working well! :)
(E3C246D2I in a Node 804 case)
One card installed so far, x4 connection!

If it's like my Asrock Rack E3C246D2I then there's a jumper to select whether the OCuLINK port is PCIe x4 or SATA. Maybe they could do it in software on the X570D4I-2T
Again my Intel board is the same - they provide a 24-pin to 4-pin adapter, it's basically to provide the soft power function -...
On further investigation that is the root port the M.2 slot is connected to. dmidecode indicates PCIE7 is PCIe bus 01:00.0 which isn't listed in lspci , possibly because the slot is empty?
Eagerly awaiting my x8x4x4 riser, but it looks like my Asrock board isn't showing multiple root ports, even thoughit's been set in the BIOS... :( Should they still show up even if no cards are installed?
