I’m interested in your findings with Plex if you have time! Thanks!
vt-d should only be needed with VMs and you don’t need a VM to use plex. Just an app or docker container.

I’ve just today gotten an F8 SSD Plus up and running on UNRAID. As a couple of people mentioned above, I had to disable secure boot and VT-d to get it to work. I’ve loaded up Plex and a few other containers. GPU doesn’t show up on the dashboard at all (even after adding GPU Statistics). Plex dashboard isn’t showing (hw) on transcodes. I’m getting periods bursts to 70%+ on N305 CPU, so I’m fairly sure CPU is handling all the transcode.
Thank you for writing this. I also purchased this EXACT same RAM and I suffered stability issues as well. If anyone knows of a quality 32 or 48 GB memory sticks that work well for this platform, please let me know!
Hello,
I have seen this :
48GB RAM in F8 SSD Plus works great! - TerraMaster Official Forum.
And also TerraMaster themselves selling memory, but crazy expensive.
For everyone wondering about Plex, I figured I would come back and give my experience with it - it seems to be working flawlessly!
I was able to enable the passthrough to the GPU, and it says its transcoding using hw - so, I am assuming that is working via the GPU.
Hmm, I installed a ‘Crucial RAM 48GB DDR5 5600MHz’ (I cant post links, apparently?) and it seems to be working fine (uptime 5 days, plaed about 15 movies from my Plex server so far). Maybe it is just that specific RAM?

Hi, has anyone of you contacted Terramaster about this VT-d issue?
I tried about 15 linux distributions and they all seem to face the same issue. Only Truenas Core (BSD), Windows 11 and TOS6 seem to work with VT-d enabled.
Does anyone have any idea what can be done?
I would really need VT-d to work, otherwise this device is unfortunately useless for me.

I received my order for CMSX48GX5M1A4800C40 (48gb stick) and that isn’t booting at all. I saw on a reddit thread that it takes some additional time to boot for the first time with a new stick, so, i’ll let it run for a bit, but I fear that I’m the first to not have success with it either.
@TeslaOwner So… did it boot in the end on your system?
I just received a replacement 48gb stick and it worked! It took an additional minute to boot, but it booted.

Glad to hear that a replacement stick did the trick for you. My F8 SSD Plus just isn’t booting at all with that Corsair 48GB stick, but is with the 16GB stock one. I’ll ask for a replacement stick.
I’ve been considering getting one of these, but I’ve been really struggling to find out whether it supports In-Band ECC (IBECC). The N305 and N100 SoCs both support IBECC, but they need to have a switch exposed in their BIOS to turn it on. Has anyone here poked through the BIOS settings of their unit and seen a setting for it at all?
It’d be sweet to have a portable all-flash TrueNAS device with ECC.
Check the Odroid-H4+ / H4 Ultra, they have an N97 SoC (better than N100) that supports IBECC and they recently added the option to enable it on the BIOS.
this is actually the device that caught my attention to start with, but the F8 as a package was more appealing for my use case and given it had the same family of SoCs in it that other manufacturers have enabled IBECC on, I was hoping that TerraMaster would’ve done the same. Unfortunately after a lengthy discussion with TerraMaster via email, it seems they aren’t going to issue a BIOS with the ability to turn on IBECC. 
Do you have a list of other boards with IBECC available on the BIOS / enabled? Thanks in advance.
Sure thing, there are a few that I’ve come across, most notably the ASUS N305S-IM-AA (it also has other variants like the N97 based N97S-IM-AA), the LattePanda Mu and LattePanda Sigma. These all have officially supported and documented IBECC implementations across a variety of Intel processors. There are a few N305 based “NAS” boards available on AliExpress that support IBECC, but it seems to be very much a gamble as to whether you’d get one with the appropriate BIOS switch available.
I’ve not been able to try any of these myself as my main aim is having a large amount of M.2 NVMe slots (even if they’re relatively slow), which none of these boards are currently capable of. It’s why I was hoping TerraMaster would just update the BIOS of their F8 and F8 Plus to have the IBECC switch available.
Thanks. Note that you can expand the single NVMe slot on the Odroid H4+ to 4 NVMe slots using this accessory (google for “hardkernel m2 4x1 card”).
Another third party option can be to use a NVMe->PCIe slot adapter and connect to it a PCI card that provides multiple NVMe slots. Google for “nvm to pcie adapter” and “sonnet pci to 8 nvm slots”.

It looks like some people had success installing TrueNAS Scale with vt-d enabled, by using nVME slots that are not behind the ASM2806 chip. See How to install TrueNAS or other system using an F8 SSD/F8 SSD Plus/424/424 Pro/424 Max? - TerraMaster Official Forum
Yep, if you have 4 SSDs or less, put them on the CPU side of the motherboard. VT-d will work.
