How to stop RAM frequency switching on Galax B760M D4?
The feeling of finally getting that buttery smooth exploration back is just incredible. The Galax B760M D4 was acting up with XMP 3200MHz enabled; the board's voltage control was too loose, causing the RAM to flip-flop between 2666MHz and 3200MHz, which created these annoying micro-stutters. I tried turning on 'Game Mode' in Windows, but the drops still happened in crowded areas, which was just unacceptable. I went into the BIOS, manually locked the memory voltage at 1.35V, and killed every single power-saving option. Monitoring with RivaTuner, I saw frame times collapse from a messy 15-35ms range down to a tight 8-12ms. I actually set the voltage too low on my first try and the system just rebooted during the loading screen, so I had to bump it by 0.02V to get it stable. Now the RAM stays at 45℃ - 52℃ with fans at 1500RPM. The frequency is now a flat line, and the game is finally playable.
