In huge team fights, my Corsair Vengeance DDR4 3200 has a response delay that makes skills lag. How do I fix this?

In the heat of a match, I'd hit a skill key and there was this tiny, infuriating delay before the character reacted. In a competitive game, that's basically a death sentence. The Corsair Vengeance DDR4 3200 had a default latency of 72-78ns, which caused micro-blocks when syncing network packets with local commands. I tried disabling the Nagle algorithm in my network settings; it lowered my ping, but the local 'feel' was still sluggish. I eventually went into the BIOS and manually tuned the primary timings from 16-18-18-36 to 16-16-16-34 and nuked every unnecessary background service. Using an input lag tester, my response time dropped from 22-30ms to a snappy 14-18ms. I did notice some random crashes during big map loads after the tweak, but loosening tRFC slightly solved it. RAM temps are 40-46℃ and CPU usage is around 60-75%. RTSS shows the sync waveform is finally smooth, and the game feels way more responsive.
