My G.Skill Trident Z5 Neo DDR5 6400 keeps stuttering during big fights in Ragnarok, why is this happening?

During those massive boss encounters, my frame rate would randomly tank from 110 FPS down to 58 FPS, which completely messed up my attack timing. I dug into the logs and found the SOC voltage on my G.Skill Trident Z5 Neo DDR5 6400 was jumping wildly between 1.15V and 1.22V, causing memory latency to swing from 62ns to 85ns. It was a total nightmare. I tried just slapping on the XMP profile, but the system just blue-screened during map loads—clearly, the silicon lottery didn't favor me here. I eventually went into BIOS -> Advanced -> Voltage and manually locked the SOC voltage at 1.25V while tweaking the memory controller offset. Running AIDA64 stress tests, my read speeds jumped from 62GB/s to a steady 68-72GB/s, and frame times finally tightened up to 11-14ms. I did notice some annoying coil whine after the first voltage bump, but that went away once I switched the load line to medium mode. Memory temps are sitting at 52-58℃ and VRM is around 55-61℃. Everything is rock steady now, though I suspect this is the absolute ceiling for this kit.
