How to reduce input latency on Maxsun B850ITX WIFI ICE?
The combat felt off—there was this eerie lag where I'd hit the button, but the character wouldn't react for about 0.1 seconds. The default memory timings on the Maxsun B850ITX WIFI ICE were producing high latencies between 92-108ns, which is a nightmare for a precision platformer. I tried increasing the page file to 16GB first, but that was a total waste of time; it didn't help the lag and actually added 4 seconds to my loading screens. I went back to the BIOS, bumped the memory voltage from 1.25V to 1.38V, and manually tightened the primary timings to 30-34-34-72. LatencyMon showed the max DPC latency dropping from 1200us to a much healthier 450-550us, making the controls feel sharp again. I did hit a wall early on where the system rebooted twice after pushing the timings too hard, but relaxing tRAS from 72 to 76 solved it. Memory temps stayed between 52°C and 58°C during an hour of intense play, and the response time is finally back to normal.
