Optimizing core scheduling for ASUS X870-A Snow?
Seeing Night City in path tracing is breathtaking, but the random stutters were absolutely killing the vibe. My ASUS X870-A Snow was struggling with the Overdrive workload, with CPU clocks jumping wildly between 4.5GHz and 3.2GHz, causing frame times to swing from 18ms to 45ms. I tried the Windows 'Ultimate Performance' plan, but while the P-Cores responded faster, the E-Core scheduling latency was still a mess, which was incredibly frustrating. I eventually went into the BIOS, set the Load-Line Calibration to Mode L3, and added a +0.02V offset to the CPU core voltage. Monitoring with HWInfo, the clocks finally locked in at 4.7-4.9GHz. I actually overshot the voltage on my first try and triggered a thermal shutdown, so I had to dial it back by 0.01V. Now the CPU stays at 75-82℃ and VRMs at 68-74℃. The scheduling is finally efficient.
