Does anyone know why Resident Evil Village keeps crashing on Crucial DDR5 4800MHz 16GB during large scene loads?

Every time I venture deeper into the castle, the game just vanishes and dumps me back to the desktop, which is honestly nerve-wracking. GPU-Z showed that the memory controller was hitting 18 - 30ms of abnormal latency when handling 4K textures, causing a total desync in VRAM data. I tried lowering the graphics settings first, and while it crashed less, the textures became a pixelated mess, which was a total dealbreaker. I eventually flashed the motherboard to the latest 2.10 firmware and forced the memory controller into Gear 2 mode in the BIOS, while locking the PCIe speed to Gen4. In follow-up tests, the data link stayed pinned at max speed, and I didn't see a single crash over four hours of play. I did have a weird issue where my USB ports stopped working for a bit after the update, but a BIOS reset and re-applying the PCIe settings fixed it. RAM temps sat at 48 - 54℃ with fans screaming at 1800 - 2100 RPM. A 3DMark stress test confirmed the link is finally stable, and the input lag is gone.
