Why is my Biostar H310MHD3 dropping frames in city areas?

Walking through the alien cities, I noticed my minimums frequently dipping to 25 FPS, which feels terrible at 4K. The Biostar H310MHD3 only supports 2666MHz RAM with very loose timings, creating a bandwidth bottleneck when the CPU handles dense NPC logic. I tried disabling every single background service in Windows, but it only gained me 2 FPS—the bottleneck was clearly hardware-level. I went into the BIOS and manually tightened the timings from 19-19-19 down to 16-18-16 and set the Windows power plan to 'Ultimate Performance'. Monitoring with RivaTuner, my minimums rose from 25 FPS to 38 FPS, and the stuttering calmed down. I did get some memory parity errors at first, but bumping the DRAM voltage from 1.2V to 1.25V made it rock steady. Board temps were 45-52℃, and the RAM stayed around 58-63℃. After three long sessions, the frame pacing is finally under control.
