Why is my G.Skill Trident Z Royal 64GB stuttering in Hitman 3?
When sneaking through crowded city maps, the CPU's memory controller struggled with the 6800MHz clock, causing frame times to spike from 12ms to 38ms. I first tried just enabling the XMP profile in BIOS, but the random read latency was bouncing between 85-110ns, which left me totally confused. I eventually manually locked the SoC voltage at 1.28V and tightened the secondary timing tRFC down to 480. Using AIDA64, I saw the read latency tighten up to 62-68ns, and those micro-stutters in crowds finally vanished. To be fair, the system crashed twice during map loads right after I tightened the timings, and I had to loosen tRAS to 84 to actually get it stable. Memory temps stayed between 55-61℃ while the VRM hovered around 60-65℃. After five full cycles of MemTest with zero errors, the scheduling parameters are finally saved.
