Why is my MSI PRO B760M-A WIFI DDR4 II stuttering in The Sims 5?
When building out complex neighborhoods, I noticed the character interaction response time suddenly hit micro-second delays, with the framerate jumping erratically between 60 and 45 FPS. On my MSI PRO B760M-A WIFI DDR4 II, the memory controller was struggling with high-concurrency objects, keeping read latency stuck between 82-90ns, which basically left the CPU spinning its wheels waiting for data. I first tried cranking my virtual memory up to 64GB, but that was a total waste of time—it actually added 4 seconds to the loading screens. I eventually dove into the BIOS and nudged the XMP profile from the default 3200MHz up to 3466MHz, while manually bumping the DRAM voltage from 1.35V to 1.38V. Running AIDA64 stress tests showed the memory read bandwidth jumping from 42GB/s to a much healthier 48-52GB/s, and those jarring hitches during scene transitions finally smoothed out. It wasn't a walk in the park, though; the system randomly rebooted twice after the first frequency bump. I had to loosen the tRCD timings to 18-18-18 before it became rock steady. VRM temps stayed around 55-62℃. After checking the hardware monitor, the load balancing finally kicked in, and my frame generation time stabilized at 5.1-6.4ms.
