Why does my Dota 2 drop frames during big spell effects with Gloway Celestial DDR5 6000?

Every time a massive team fight broke out, my FPS would plummet from 120 to 40, and the anxiety of missing a spell was real. The default 36-36-36-76 timings on this Gloway 6000MHz kit have some compatibility quirks on certain boards, causing sync delays. I tried the 'Auto Overclock' feature in the software, but that just increased the micro-stutters—a total fail. I went into the BIOS, bumped the voltage from 1.25V to 1.32V, and loosened tRFC from 480 to 520. Using RivaTuner, I saw memory latency stabilize from 72ns to a tight 64-68ns, and my minimums climbed from 35 to 58 FPS. I actually hit 1.35V at first and the RAM temps shot up to 64℃, so I had to set a custom fan curve to kick in at 50℃. GPU stayed at 62-68℃ and VRAM at 76-82℃. Benchmarks show the drops are gone, and the input lag feels non-existent now.
