Why does Dune Awakening keep stuttering during sandstorm scenes with G.Skill Trident Z Neo DDR5 6400?

While tracking giant sandworms, I hit these millisecond-long freezes that are absolute killers during precision dodges. The stock timings on my G.Skill Trident Z Neo DDR5 6400 were struggling with the massive environmental data, causing memory controller latency to swing wildly between 72-85ns. This sent my frame times jumping from 12ms to a jarring 35ms. I first tried enabling 'Ultimate Performance' in Windows, but that was a waste of time—it didn't fix the stutters and just pushed my RAM temps up to 65,0C. I eventually dove into the BIOS and manually tightened the primary timings to 32-38-38-76 and bumped the voltage from 1,35V to 1,40V. Checking HWiNFO, the latency tightened up to 62-68ns, and the game finally felt fluid. I actually hit a few random reboots when I first tried to crush the tRFC parameter, but once I backed it off to 520 cycles, it stayed rock steady. RAM temps settled around 52-58,C. After some stress testing, the read/write curves are smooth, and frame times are now locked in at 11,2-13,5ms.
