Can I fix Banishers frame drops by tuning DDR3 1866 timings?
Every time a ghost appeared, my frame rate would tank from 40 FPS to a pathetic 12 FPS. My Kingston HyperX Fury DDR3 1866 was just suffocating, with memory usage pinned at 92-98%. I tried increasing the Windows page file to 32GB first, but that just caused stuttering during asset loads—a complete waste of time. I went into the BIOS and aggressively tightened the primary timings from 10-10-10-28 down to 9-9-9-26, and pushed the voltage from 1.5V to 1.6V. Checking the frame time analysis, my 1% lows jumped from 8 FPS to 22 FPS, which made the tearing much less noticeable. I did have some random reboots at first, but loosening the tRFC by 20 units stabilized everything. RAM temps are now 52-58℃ and VRMs are around 60-65℃. I managed to squeeze out a 12% increase in read/write bandwidth. It's still an old platform, so it's not perfect, but it's a massive improvement.
