Hmm, do you mean that setting on the Management Access Settings page?

I do have these in my X9DRi-F. They build a cache pool: 2x Lycom DT-120 PCIe x4 M.2 Adapter 2x Samsung 970 EVO 250GB M.2

Thanks a lot.

Stupid question: Some motherboards do have slots declared as "x8 (in x16). What happens if I put a 1-slot x16 graphics card into these. Will this work for e.g. Plex transcoding? Thanks.

Sorry, what is a myth? Must be my bad english, sorry. Here's a screenshot of a E-2288G for example. The same is true for 9900K - just to mention two:

I'm currently in the same boat - actually I came here to ask a similar question. Thanks for your detailed answer ramblinreck47. I'm screwing my head thru the details since two days and all I got was that current Intel CPU/GPU combinations seem to limit PCI lanes to 16. Is this correct? And if this is correct, are there different Intel APUs with more lanes? Consider 3x PCI-E x8 PLUS 2x M.2 x4. I can't build that with Intel APUs? I really would like to move from "Unraid NVIDIA" to plain "Unraid" but the current Intel APUs seem to be limited IMHO.

No. All USB devices are plugged into the Mainboard (Supermicro X9DRi-F). As I said, it worked until last week. The Server is running 365/24/7.

Thanks for looking into it. These two USB devices are passed through to two Unraid VMs. These devices didn't show up on dashboard and they didn't show up on Main page. It works that way since a year. Since some days (under a week) they are shown on dashboard. They only thing that has been changed in that week are the Plugins UD, Wireguard and CA. It's no big deal and I thought that new Passthrough Switch might be the reason. Hence I didn't use that switch til now.

I see. Diagnostics attached. tower-diagnostics-20200201-2035.zip

Sorry, my fault (sda was a typo). sdb and sdc are shown as Unassigned devices on dashboard but not on Main page. Both are USB-Devices passed through to two VMs. Uploaded diagnostics still applies.

Did it exactly by the word. Looks exactly like before. sda/sdb are shown on Dashboard but not on Main page. There's no way to mark these two devices as passed-through.

Diagnostics attached. sda and sdb are two USB sticks that are passed thru to two Unraid VMs. Since the latest UD update today these are shown on the dashboard while correctly missing on the main page IMHO. Thanks for looking into it. tower-diagnostics-20200131-1420.zip

Never seen that before - think it came with the UA update today. The Main page shows no Unassigned Devices, the Dashboard shows two Unassigned Devices - at the same time. These two devices are passed through to two VMs. Bug or feature? Thanks.

Here's a picture of that powerboard in a Supermicro SC846E16 JBOD case connected to a BPN-SAS2-EL1 backplane. It's the last picture: https://forums.unraid.net/topic/78165-how-many-tbs-is-your-unraid-server/?do=findComment&comment=797795

The name of a powerboard is "CSE-PTJBOD-CB2". It works perfect with "BPN-SAS2-846EL" backplanes. There's a newer powerboard "CB3" but I don't have any experience with it.
