How to fix frame drops with G.Skill Trident Z5 DDR5 6400?
Whenever a full-screen special effect triggers during co-op raids, the screen hitches in a rhythmic pattern, which is incredibly jarring at 6400MHz. I found that the default XMP profile on my board had a slight voltage offset, causing the memory controller to spike to 82-150ns latency when hammering through particle data. I first tried Windows High Performance mode, but while the CPU stayed pegged, the memory latency kept jumping around, which was honestly a nightmare to debug. I eventually dove into the BIOS, manually locked the DRAM voltage at 1.38V instead of 1.35V, and switched tRFC from Auto to 480 cycles. Looking at the RTSS frame time graph, those jagged spikes were finally crushed down to a steady 11-16ms range. I actually tried pushing the timings to 30-34-34 at first, but the system just blue-screened during map loads until I backed them off to 32-38-38. Temps settled around 52-58℃. AIDA64 confirmed a rock-steady read speed of 58GB/s, and my frame generation time finally stabilized at 5.1-6.4ms. It's a bit of a hassle to manually tune, but it's the only way to stop the hitching.
