I bought this workstation for a specific purpose, to install 3 RTX 4060ti cards and train a small model for AI. I installed the 3 GPUs using 3 PCIe to external occulink cards. After installing Ubuntu 22.04, and getting the NVIDIA drivers installed, The GPUs all showed up perfectly. Reducing the PCIe speed in the BIOS seems to be keeping things stable. The model training has been going for about 6 days now, without a hiccup. I'm so impressed with this Workstation, I may just make it my daily driver when this AI model is trained.
