November 28, 2025Nov 28 Hello,I recently changed over motherboards from a DDR4 setup to a DDR5 setup. The Unraid system came from my main gaming rig that just got an upgrade and since doing that, my system cannot get more than 3 hours uptime.CPU, MOBO, RAM got an upgrade from DDR4 to DDR5. Same USB.I've tried playing with the docker network settings around iplan/maclan to no success.I managed to type diagnostics 5 minutes after it happened. Please see logs attached.Any help would be greatly appreciated. Edited November 30, 2025Nov 30 by The Fragile One

The default clock profile is 4800.The link you have provided says Unraid can handle 2x max 5200.I am going to change the clock of the RAM to be default at 4800.

December 2, 2025Dec 2 Author Since turning off EXPO ram and leaving the speed at 4800m/s(default), my crashes have gone from 3 hours to nearly 2 days.The system still responds fine through physical KB/mouse (just no internet access) and the unraid is not contactable by any other machine.I was actively on the server when it disconnected this time and managed to get the diagnostics. (attached).Would you be able to see what is going on through the diagnostics? kooori-diagnostics-20251202-1506.zip

December 2, 2025Dec 2 Author Thanks JorgeB, I appreciate you looking into this.Looks to be an Intel driver issue with Linux. I'm running the exact hardware as this other Unraid post which has a solution in it. I'll give it a try and if it doesn't work, I'll get a new NIC.6.11.5 - igc 0000:09:00.0 eth0: PCIe link lost [Ryzen 9 7950X] [SOLVED] - General Support - UnraidThanks for your time
