SOLVED: My odyssey with a new server with Intel A40 Pro.

[Itow]

Hello, I would like to share my experience building a new server for Jellyfin.

Server specifications:

• W680D4ID-2T/G5/X550
  
• Intel® Core™ i5 Prozessor 14500T
  
• 2x 32GB Kingston DDR5-4800
  
• Kingston Furry 1Tb M.2
  
• Intel A40 Pro
  

OS:

• Debian Bookworm (DietPi)
  

Kernel:

• 6.11.3-x64v3-xanmod1
  

Jellyfin:

• Docker Linuxserver.io latest with OpenCL-Intel
  

Power consumption (measured at the UPS) :

• Idle ~50 Watt
  
• Transcoding of multiple streams 4k>1080p ~80Watt
  

First problem: temperatures 

The X550 chip easily reaches temperatures above 100°C and the chipset above 70°C, while the CPU reaches 55°C in idle mode and 80°C under load.

After modifying the chassis and adding fans:



Second problem: server crashes after a few minutes of transcoding 

This was really a problem and I could not find the culprit. I ran stress test on cpu and memtest86 for hours without any problem.
For gpu I was not able to find an easy to use stresstest.

I found that the HuC and GuC firmware were not compatible with the GPU, so I installed the Intel firmware from backports, which solved the problem.
I was only able to solve the crashes that occurred after a few minutes of transcoding when I disabled ASPM for the GPU in the BIOS.

The only thing that still doesn't work is AV1 encoding.

At the moment I'm happy that the server is lightning fast and stable, but AV1 would be the cherry on top.
