How to stabilize memory performance for Alan Wake 2 on B550M?
Just as the lighting effects looked perfect, I noticed the frame rate started fluctuating in a weird, jagged pattern. At 4K, this was incredibly jarring, and I was determined to crush it. I found the Soyo SY-Yanlong B550M was bouncing the RAM frequency between 3000MHz and 3200MHz, causing frame times to swing wildly between 18.2ms and 26.4ms. I ran a Windows Memory Diagnostic first, which showed zero errors, but the stuttering remained—a total dead end that just made me more obsessed with fixing it. I went into the BIOS, forced the RAM to a locked 3200MHz, and nudged the voltage from 1.2V to 1.35V. Looking at the RivaTuner graph, the frame time finally became a straight line. I did have one instant reboot during the first attempt until I loosened the tRCD by 2 cycles. Now, RAM temps are 40-45℃ and VRMs are at 58-63℃. The smoothness is night and day compared to before.
