Why is MGSV stuttering on my MSI PRO B760M-A WIFI DDR4 II?
Whenever I'm sneaking into an enemy base, the screen just hitches. It's a nightmare for timing your takedowns. The memory controller on the MSI PRO B760M-A was struggling with the Definitive Edition's asset streaming, and I spotted 82-90ns latency spikes in the secondary timings, which basically left the CPU idling. I tried just slamming the Extreme XMP profile on, but the system hit a BSOD after ten minutes—total waste of time. I eventually dove into the Advanced Memory settings and manually crushed tRFC from 560 down to 480, while bumping the DRAM voltage from 1.35V to 1.38V to keep the signal from collapsing. In AIDA64, the read latency dropped from 85ns to a tight 70-74ns, and the input lag just vanished. I actually had a few failed boots at first because tRFC was too tight, but backing off tRCD by 2 units fixed it. Memory temps stayed around 42-48℃ with a rock steady 3200MHz clock. Checked the performance monitor and the frame time graph is finally flat, sitting between 5.1-6.4ms.
