How to stabilize G.Skill Trident Z5 DDR5 6400 for Need for Speed?
The default XMP profile on these sticks is a joke. At 6400MHz, every reboot takes two minutes for memory training, and once in-game, my FPS would tank from 120 to 70. It feels like the manufacturer just phoned it in on compatibility testing. I tried using Windows memory compression, but the system just froze—a rookie mistake that taught me I needed a BIOS fix. I bumped the VDD voltage from 1.35V to 1.4V, locked the SoC voltage at 1.25V, and loosened the tRFC slightly. RTSS showed my 1% lows climbing from 62 to 95 FPS, with a tight 4-8 frame variance. The sticks hit 62℃ after the voltage bump, so I had to slap a small cooling fan on them to bring temps down. CPU stays at 72-78℃. I saved this as a BIOS preset so I don't have to do this again after an update.
