Why is my MSI A520M-A PRO struggling with resource scheduling?
Whenever I hit the main city loading screen, the game just completely freezes for three to five seconds, which is an absolute nightmare in a modern 32GB environment. The memory controller on the MSI A520M-A PRO is way too conservative by default, causing memory latency to swing wildly between 98ns - 115ns, which just can't keep up with real-time asset decompression. I first tried bumping the virtual memory to 32GB in Windows, but that actually made loading times 15% slower, which left me totally baffled. I eventually dove into the BIOS and tightened the primary timings from 22-22-22-52 down to 18-20-20-42, while nudging the DRAM voltage from 1.2V to 1.35V. Running AIDA64 stress tests showed read speeds jumping from 3400 MB/s to 4100 MB/s. It wasn't a smooth ride though; I hit two immediate BSODs upon the first boot until I loosened the tRAS to 46 to find some stability. RAM temps settled at 42°C - 48°C and the VRMs hovered around 55°C - 62°C. Verified via benchmark that bandwidth utilization is finally steady.
