Problems getting Intel ARC A310 working on HL-8 for transcoding

Hey guys! Hoping someone could give me some advice with my HL-8 and getting the intel arc a310 working for transcoding. I got the fully burned in option with the Aorus b550i pro ax mobo and the AMD 5500gt CPU. My problem is that when i have the gpu installed, my system will not make it past the mobo logo screen while booting, or if it does i cant tell as it is stuck on a blank black screen/no video output. I have updated the mobo firmware to the latest Ff revision, enabled above 4g decoding, set resizeable bar to auto, enabled IOMMU and set it to force the onboard apu graphics card for output in the bios as i am only wanting to use the arc card for transcoding. I am running proxmox right now but tried to boot to rocky 8, ubuntu 24.04 desktop and server, and debian 12. None of them booted to shell/desktop successfully which leads me to think im missing something with the bios settings. Any help is appreciated.

Note: Rocky 8 would make it to the user login screen but would freeze as soon as the image loaded onto the screen. I tried installing intels drivers but that did not help.

Not necessarily. Those are all various flavors of Linux.

If it were me, I’d try to narrow down if the system is getting stuck in the POST process or OS boot process, and do so with a general observation that there are lots of reports of freezing and crashing of the Intel cards attributed to many hardware and software reasons. I don’t see an exact match for your situation, but in general there appear to be … issues. I think Craft Computing uses an A310 in an HL-8 chassis, but does so with a different mobo.

When you talk about Rocky, Ubuntu, Debian .. I assume you mean you installed those as the bare-metal OS. Did you do the OS installs with the A310 installed? Or did you install the OS, then put the A310 in? You could take a look in boot.log, syslog, and dmesg to see if there are any messages that might help researching what is causing the hang.

I assume from your description that the motherboard appears to be working fine (although there could be a PCIe-slot specific issue). Do you have any way of testing the A310 in another system to see if it works with some different hardware? What specific brand/model, the Sparkle?

One thing I might do, just to confirm the hang is occurring loading the Linux drivers, is boot a non-Linux OS. For example, FreeDOS or a Windows trial. Not to use it, with or without the card, just “will that other OS boot successfully without hanging with the A310 sitting idly in the slot?” If it will, then we’re looking at something Linux specific (not sure how mature Intel’s Linux GPU drivers are in general). If it won’t, then we’re probably looking at something hardware related; a defective A310, BIOS support, or system conflict.
