Optimizing Corsair Vengeance DDR5 6000 64GB latency for LoL
During intense team fights, I was getting these tiny, erratic jumps in the image. It's a small thing, but in a competitive game, it's enough to make you lose your mind. Even with 64GB of Corsair Vengeance DDR5 6000, the high module density caused the memory controller to swing between 88ns and 95ns of latency. My first instinct was to just slap on the XMP profile, but that led to a nightmare of random boot loops. I eventually went manual in the BIOS, locking the frequency at 6000MHz and setting the FCLK divider to 2000MHz, while pushing the voltage to 1.38V. AIDA64 showed the read latency tighten up from 92ns to a crisp 65ns - 69ns, and the game suddenly felt buttery smooth. I did run into an issue where the RAM hit 62°C after the tweak, so I had to add a dedicated spot fan to bring it down to 52°C - 56°C. MemTest86 passed with zero errors, and the mouse response now feels perfectly synced.
