How to lock memory frequency on Galax B360M-M.2 for stability?
Just as the lighting effects in the game looked perfect, I noticed the frame rate started doing this weird sawtooth fluctuation. At 4K, this kind of inconsistency is incredibly distracting, and I was determined to crush it. I realized the RAM frequency on my Galax B360M-M.2 was bouncing between 2400MHz and 2666MHz, causing the frame times to swing wildly between 18.5ms and 28.2ms. I first ran the Windows Memory Diagnostic tool, which showed zero errors, but that did absolutely nothing for the actual feel of the game. It was a technical dead end that just made me more obsessed with fixing it. I went into the BIOS and forced the memory frequency to a locked 2666MHz, while nudging the voltage from 1.2V to 1.35V. Looking at the RivaTuner graph, the frame time finally became a flat line. I did have one instant reboot during the first attempt, but relaxing the tRCD by 2 cycles fixed the instability. RAM temps are sitting at 38-44℃ and VRMs are at 55-61℃. The smoothness is night and day now.
