How to fix memory latency spikes on the Onda B760ITX-B4?
During fast dodges, I kept getting these tiny micro-stutters that are incredibly distracting in an action game. The default memory voltage on the Onda B760ITX-B4 was causing latency spikes of 15ms - 22ms during high-speed data swaps. I tried lowering the graphics settings, and while the average FPS went up, the stuttering remained—proving it was a hardware-level bottleneck. I went into the BIOS, carefully bumped the DRAM voltage to 1.35V, and tightened the timings from 18-22-22-42 to 16-18-18-36. In RivaTuner, the frame time variance shrunk from a messy 16-45ms range down to a stable 12-16ms. I actually messed up and set the voltage to 1.45V once, which bricked the boot process until I cleared the CMOS. RAM temps are now stable at 40°C - 46°C and the board core is at 50°C - 55°C. After three hours of gameplay, the stutters are completely gone.
