§ 02Notes

Context

Per-core Curve Optimizer tuning on Ryzen is normally a multi-day chore of crashes, stress benches, and notebook math. The previous generation of auto-tuners optimized for steady-state endurance and missed the Vdroop crashes that happen during sudden light-load transitions, which is the actual failure mode in real workloads.

§ Process

Process

Built around a transient-stability philosophy: testing prioritizes Gap Pairs (non-adjacent cores under load) and Cross-CCX Pairs over neighbor pairs, then deliberately whips the CPU between heavy heat-soak and light boost loads to provoke the back-to-boost crash window. Per-core silicon quality is measured up front via VID and temperature deltas, then a global aggressiveness level is found while preserving each core's individual offset. Thermal failures ( are vetoed from triggering voltage backoff, a death-loop safeguard the previous generation lacked. State is persisted between runs with crash recovery via heartbeat file.
