Optimizing power efficiency for Dying Light 2 on Onda A520-VH-W
Moving fast through the city ruins caused my core temps to skyrocket to 92℃, which forced the clock to drop from 4.0GHz to 3.2GHz. You can really feel the performance dip. The VRM on the Onda A520 hit a thermal saturation point where the heat just pooled around the inductors. I tried limiting the maximum processor state in Windows, but while it saved 5℃, I lost about 15 FPS—which actually made me excited to try some hardcore undervolting. I went into the BIOS, dropped the CPU core voltage to 1.1V, and switched the chassis fans from 'Silent' to 'Performance' mode. The monitoring panel showed core temps stabilizing at 72-78℃, with frequency fluctuations narrowing to 3.8-4.0GHz. I hit a snag where the system rebooted during boot-up after the first undervolt, but bumping it back to 1.12V made it perfectly stable. VRM temps are now 85-91℃. Switched the performance profile to 'Extreme' via the software, and it's finally behaving.
