Why is my Corsair Vengeance DDR5 64GB lagging in League of Legends?
Lagging in League is bad enough, but doing it with 64GB of RAM is just pathetic. After analyzing the timings, I found that the default XMP 36-36-36-76 on this Corsair Vengeance kit had a latency of 82ns when handling small data packets, causing a noticeable delay in command response during teamfights. I tried closing every background app, which boosted my FPS but didn't fix that 'sluggish' feeling in the controls. I knew I had to go into the BIOS. I manually tightened the primary timings to 30-34-34-68 and bumped the DRAM voltage from 1.35V to 1.40V. In AIDA64, the latency dropped to 64ns - 68ns, and the game finally felt responsive again. I did hit a wall when I tried 28-28-28—the system just blue-screened instantly—so I had to loosen tRAS to 72 to get it stable. RAM temps are now between 52℃ - 60℃. I used the BIOS export tool to save the profile, and temps are staying at 52℃ - 60℃.
