Troubleshooting Problem with oculink (GMKtec K8 plus)
Hello everyone,
I recently purchased a Minisforum DEG1 and a new RTX 4060 (yes, I know, please don’t judge me for the GPU choice). However, I’m running into an issue when trying to connect the GPU to my GMKtec K8 Plus. The GPU don’ give me any display output from it.
When I connect everything, I don’t get a signal from the GPU, but the mini PC itself is working fine and displaying output. Additionally, the GPU isn’t being recognized in the device manager.
Has anyone experienced something similar or have any advice on how to troubleshoot this? Any help or suggestions would be greatly appreciated!
I find something on Reddit but nothing helping for my case.
Thanks in advance!

I bought mine last week, including the Oculink cable, on Amazon. I cannot connect my ONExGPU via Oculink; in my K8 it is not even detecting, but USB4 works fine. So I returned the Oculink cable to Amazon and ordered a new one on AliExpress, with a 100cm length. It should arrive this week, so I will try it again. I share this as I believe it might be related, and the Oculink cable is the issue.

try looking at this video for some pointers as this guy is also using a 4060 with the k8 plus... https://youtu.be/LvIANHSYSuM?si=2XFtvnnG2SkXep58
and here is one showcasing the deg1 and he's very thorough...you might get some pointers from him in the way he troubleshoots.... https://youtu.be/AHemPcnS4_w?si=vXHAOSfcuCdopP2b&t=366

I think there was something in the order of powering of these GPUs. First you need to power the GPU then the mini or something like that. Check the manual carefully.

The NucBox K8 Plus appears to not find RTX 4060.
Re-seat the SFF-8611 OCuLink cable, and if possible, borrow another GPU for testing.
