How to fix memory bandwidth bottlenecks on Onda 9D4-DVH?
The moment I stepped into the main city, my FPS tanked from 60 to 20. The optimization is just abysmal, and it's honestly depressing. The default timings on the Onda 9D4-DVH are way too conservative, leaving bandwidth stuck between 32-36GB/s, which can't handle the asset streaming. I tried closing every background app, but I only gained 2 FPS—a total waste of time. I went into BIOS, forced the RAM from 2666MHz to 3000MHz, and crushed the timings from 18-22-22-42 down to 16-18-18-38. 3DMark CPU scores jumped by 12%, and my city lows went from 18 to 32 FPS. I crashed twice during save loads at first, but bumping the voltage from 1.2V to 1.35V fixed it. Board temps are 45-52℃ and RAM is 42-48℃. I backed up the config, but this board is definitely pushing its limits.
