A user on r/LocalLLaMA reported that adding a second RTX 3060 prevented the loading of large Mixture-of-Experts (MoE) models like Qwen3.5-122B, which previously worked with CPU offload on a single card.

The issue was resolved by reducing the number of layers loaded into VRAM to 12 for the 122B model and adjusting GPU priority settings after a PC restart.

This workaround allows dual RTX 3060 configurations to successfully load large MoE models that were previously inaccessible.
