Why does Atomic Heart keep stuttering during heavy combat with Asgard Snow DDR5 6400 32GB installed?

Whenever I hit a massive wave of robotic enemies, the screen just hitches for a few microseconds, which completely ruins the combat flow. I noticed the default XMP profile on the Asgard Snow DDR5 6400 was struggling; the memory controller load was jumping wildly between 62% - 68%, causing read/write latency to swing from 75ns - 88ns. I tried enabling Windows Game Mode to prioritize the process, but the drops kept happening during specific transitions, which was honestly baffling. I eventually dove into the BIOS Advanced settings and tightened the primary timings from 32-39-39-76 down to 30-36-36-72, while bumping the memory voltage from 1.35V to 1.38V. After running AIDA64, the latency finally converged to 64ns - 68ns, and the response felt snappy again. It wasn't a smooth ride, though—the first time I pushed the timings, the system BSOD'ed ten minutes into the game. I had to relax the tRFC to 480 before it actually stayed stable. Temps hovered around 54℃ - 59℃, and the heatsinks felt warm to the touch. Checking the performance monitor, the frame generation time finally leveled out at 5.1ms - 6.4ms.
