Civ VII is dropping frames and throwing checksum errors during late-game calculations on my Gloway 6000!

During complex late-game turn calculations, the frame rate would dip sharply for about 0.2 seconds, and that stuttering became really noticeable after a few hours of play. The Gloway Celestial DDR5 dies were slightly unstable at 6000MHz, and my event viewer was littered with WHEA-Logger memory errors. I first tried 'Auto' voltage in BIOS, but the voltage was jumping wildly between 1.2V and 1.4V, which actually made the crashes more frequent. I eventually locked the voltage at 1.35V and loosened the primary timings from 30-36-36-76 to 32-38-38-80 to give the system some breathing room. After 3 passes of TestMem5, the error count stayed at 0 and the frame drops improved significantly. I still had one random reboot in the first 10 minutes, but bumping the SOC voltage to 1.2V finally killed the problem. Temps are sitting between 52-58℃, and frame times are now stable at 6.2-7.1ms.
