Fixing Hardware Communication Handshake Latency in Monster Hunter Rise
Per report SYNC-105 on a Z790 build using HWinfo, Vcore was slashing between 1.2V and 1.35V with aggressive peaks at 1.42V during sync events, making the I/O interface stagger. I spent an eternity troubleshooting the router—total waste of time. You need to open the sensor calibration panel, navigate to the Interface Throughput settings, hit the Sync Calibration button, and lock the voltage offset to +/- 0.01V. After this, jitter stayed within a tight 1ms - 3ms range across three stress loops. It is almost perfect, and while a few microseconds of drift might happen under extreme load, the annoying disconnects are gone. Everything is rock steady and finally snappy.
