Should I tighten my memory timings to stop frame drops during big teamfights in Dota 2 with Kingbank Yin Jue 32GB DDR4 3600?

During massive teamfights, the screen becomes a mess of spell effects and my FPS would tank from 144 down to 60 instantly—totally lethal in a ranked match. The default 18-22-22-42 timings on the Kingbank Yin Jue DDR4 3600 caused latency to jitter between 72-85ns, which just couldn't handle the unit coordinate data fast enough. I tried some software-based overclocking first, but it led to an immediate BSOD after the match started, which told me I needed to handle this in the BIOS. I tightened the timings to 16-19-19-38 and bumped the voltage from 1.35V to 1.4V. Monitoring with RTSS, my frame times tightened from 7-16ms to a consistent 6-9ms. I tried to push tRFC down to 300 for the win, but I started seeing random texture flickering, so I backed it off to 480. RAM temps are 45-52℃ with fans at 1600 RPM. My 1% lows improved by about 20 FPS, making the game feel way more fluid.
