Is Asgard Thor DDR5 6400 32GB causing lag in Far Cry 7?
Watching the jungle foliage turn into a slideshow was infuriating; it was a clear sign that my memory bandwidth was hitting a wall. My Asgard Thor DDR5 6400 32GB was running in Gear 2 mode, and the ratio between the memory controller and frequency was causing high latency in the 85-102ns range. I tried lowering the texture quality first, which gained me about 10 FPS, but the game looked like a blurry mess—absolutely not an option. I rebooted into the BIOS, forced the memory mode to Gear 1, and pushed the VDD voltage up to 1.42V. In AIDA64 bandwidth tests, the read speed jumped from 62GB/s to a solid 88-94GB/s, and the frame drops disappeared. I did have a scare where the system failed POST and the memory LEDs were blinking like crazy during the first Gear 1 attempt, but I got it to boot after slightly downclocking to 6200MHz. Memory temps stayed between 48-54℃, while the motherboard VRMs hit 65-71℃. After six rounds of stress testing, the system is rock steady, though Gear 1 is definitely more temperamental than Gear 2.
