How to stop Wi-Fi interference from killing FPS on Galax B760M D4?
The Wi-Fi module on this board is basically an EMI nightmare; whenever network traffic spiked, my FPS looked like an EKG monitor. The Galax B760M D4 Wi-Fi card generates high-frequency noise at full load, introducing a 5-10ms lag on the PCIe bus. I tried disabling Bluetooth in the driver first, but the spikes stayed—it felt like I was just guessing at this point. I eventually went into the BIOS, killed all unnecessary wireless management services, and forced the PCIe slot to Gen3 instead of Auto. Using RTSS, I saw the frame times collapse from a wild 16-32ms range down to a tight 11-14ms. I did have a weird issue where some peripherals lagged after the PCIe change, but a quick unplug-and-replug of all USB ports fixed it. CPU temps are 62-68℃ and VRMs are 65-72℃. I exported the logs to confirm the stability, and the fans are steady at 1400-1600RPM.
