How to sync memory timings on ASRock Z370M Pro4 for Dota 2?
The difference in fluidity during teamfights is night and day; the frame rate finally stopped looking like an EKG monitor. The memory controller on the ASRock Z370M Pro4 was struggling with mixed 2400MHz and 2666MHz sticks, creating a 12-15ms sync delay that tanked my minimums from 90 FPS down to 42 FPS. I tried killing all background apps first, but that only gave me a measly 3 FPS boost, which was basically useless. I eventually went into the BIOS and forced all sticks to 2400MHz with unified timings of 16-18-18-36. Using a frame time analyzer, the jitter dropped from 14-45ms to a tight 6-12ms. I tried syncing them to 2666MHz at first, but the system just randomly rebooted until I bumped the memory voltage to 1,35V. Now RAM temps are 42-48C and the chipset is at 55-60C. The in-game benchmark confirms a smooth curve with frame times locked at 5,1-6,4ms. The gameplay finally feels fluid.
