Dual 5060Ti P2P failure: PCIe topology bottleneck
chocofoxy · reddit · 2026-09-02
Attempted to enable P2P on dual RTX 5060Ti cards to speed up Qwen 3.8 27B long context inference. Although the driver hack listed P2P as available, the service hung during init due to a PCIe topology mismatch (one card on CPU, one on chipset). The fix requires a PCIe splitter riser or a new motherboard.
