How to stabilize high-frequency RAM on ASUS ROG Z890-A Snow?
Every time I hit a high-intensity fight in the final circle, the screen would just hang for about 0.5 seconds, which is incredibly tilting. I had the ASUS Z890-A Snow running RAM at 7200MHz, but the VDD voltage around 1.35V was causing noticeable ripples. I first tried downclocking to 6400MHz for stability, but my 1% lows tanked from 110 FPS to 85 FPS, which was a dealbreaker for me. I went back into the BIOS Advanced Mode, bumped the VDD voltage to 1.42V, and loosened the tRFC timing from 480 to 520 to give the system some breathing room. In MemTest86, the error count went from 3 per hour to zero. I actually messed up the first attempt by pushing it to 1.5V, which triggered the motherboard's overheat protection and shut everything down—a loud reminder to be precise with voltage. RAM temps stayed between 52-58℃ and VRM temps were 65-71℃. After four hours of grinding, the stutters are gone and the input feels instant.
