User attempts P2P GPU setup for LLMs, faces motherboard limitations

By PulseAugur Editorial · [1 sources] ·

A user on Reddit's r/LocalLLaMA subreddit attempted to enable peer-to-peer (P2P) communication between two NVIDIA 5060 Ti GPUs to improve performance with large context models like Qwen 3.8 27b. The user followed a guide for open GPU kernel modules but encountered issues where the server hung during initialization and the GPUs reached 100% utilization. The user identified a potential motherboard limitation as the cause, suggesting that a different motherboard or a specific riser setup might be necessary for successful P2P implementation. AI

IMPACT This technical exploration highlights potential hardware bottlenecks for running large context models locally, suggesting that P2P GPU communication could be a future optimization path.
