Is my Onda B760ITX-B4 causing UI stutters in The Sims 5?
As my community grew, every single menu click came with this weird 0.3-second delay that drove me insane. The memory controller on the Onda B760ITX-B4 was choking on massive entity data, with latency swinging between 82 - 115ns, which completely blocked the UI thread. I tried cranking the virtual memory up to 32GB, but that did nothing for the lag and actually introduced micro-stutters during disk I/O—a frustrating dead end. I went back to the BIOS and manually tightened the primary timings from 18-22-22-42 down to 16-20-20-38, while bumping the voltage to 1.35V. LatencyMon showed the peak DPC latency plummet from 1.5ms to about 0.4ms, and the UI suddenly became lightning fast. I did hit two random reboots during the first timing run, but loosening the tRFC by 10 units stabilized everything. RAM temps are now 45 - 52℃ and the heatsinks are at 55 - 62℃. After stress testing, the scheduling is optimal and the input response feels incredibly tactile.
