Total War: Warhammer 3 frames tank during huge battles with Crucial DDR5 4800, should I use dual channel?

It's an absolute rush seeing thousands of units clash on screen, but having your FPS dive from 90 down to 30 in a split second is a total mood killer. The Crucial DDR5 4800 was choking on the massive amount of unit data in single-channel mode, leaving the CPU idling while waiting for memory. I tried adding more virtual memory first, but the frame swings stayed just as bad—another useless attempt that proved the problem was the physical hardware path. I reseated the sticks into slots 2 and 4 to force dual-channel mode and tweaked the tRFC timings in the BIOS. In 3DMark's CPU physical test, my bandwidth jumped from 32 GB/s to a steady 58-62 GB/s, and the stuttering vanished. The system took a good 30 seconds for memory training on the first boot after the swap, which was a bit nerve-wracking, but it settled down once I hit Windows. RAM temps stayed between 42-48℃ and VRM temps hit 58-64℃. The performance panel confirms the bandwidth is now maxed out at 58-62 GB/s.
