Hitman 3 keeps crashing with memory overflow in crowds with my Corsair LPX. How do I fix this lag?

The game just went black while I was infiltrating the Dubai hotel; it felt like the system suddenly lost access to the memory addresses, which is a nightmare in a stealth game. The default XMP profile on these Corsair Vengeance LPX sticks was causing the memory controller to hit sync delays of 105-118ns when processing heavy NPC logic. I tried dropping the graphics to Medium, and while the crashes stopped, my minimums tanked from 55 FPS to 40 FPS, which was unacceptable. I went back into the BIOS and forced the DRAM voltage to 1.37V and locked the virtual memory page file at 32GB. Monitoring with MSI Afterburner, the latency stabilized at 76-82ns, and I managed 5 hours of gameplay without a single hiccup. I actually tried 1.32V first, but it triggered two BSODs instantly until I added that extra 0.05V. CPU temps stayed around 62-68℃ and VRMs at 55-61℃. A full MemTest86 scan showed zero errors, with sticks idling at 58-63℃.
