Does Galax B760M D4 Wi-Fi cause USB interference?
While hunting machines in the wild, I noticed a tiny hitch every few seconds that totally messed up my timing. It turned out the Wi-Fi module on the Galax B760M D4 Wi-Fi was creating electromagnetic interference with the adjacent USB 3.0 ports, pushing input lag up to 20-30ms. I tried swapping USB ports, but the stutters stayed—a cautious attempt that got me nowhere. I went into the wireless adapter's advanced settings, switched from 802.11ax to ac mode, and locked it to the 5GHz band. In RTSS, the jagged frame time graph smoothed out into a flat 7-12ms range. My ping actually jumped by 10ms at first, but reconfiguring my DNS servers fixed the speed. The board core is at 48-53℃ and the wireless module is around 60-65℃. Input lag tests confirm the interference is gone, though RAM temps still hover around 58-63℃.
