How to fix voltage instability on Onda A520-VH-W in Project Orion?
Exploring the cyberpunk city is amazing, but these 0.1-second micro-hitches were killing the immersion in such a fast-paced game. I found that the power delivery on the Onda A520-VH-W was struggling when the CPU boosted to 4.4GHz, with voltage ripples hitting 0.12V, which triggered instant clock drops. I tried enabling power-saving modes in Windows, but while it cooled things down, I lost about 20 FPS, which didn't actually fix the underlying hitching. I went into the BIOS and capped the max boost at 4.1GHz and tightened the fan response time to 0.1 seconds. Looking at the RivaTuner frame time graph, the jagged spikes were flattened down to a smooth 12-16ms. I tried 4.2GHz, but the system crashed twice during stress tests until I tweaked the SOC voltage to 1.1V. Now the CPU stays between 65°C and 72°C. After three hours of gaming, there isn't a single stutter left, though the lower clock speed is a slight trade-off.
