How to calibrate signal for Corsair Vengeance LPX DDR4 3200?
That horizontal tear right in the center of the screen was eye-searing, especially while flying on a Griffin; it just broke the whole immersion. I tracked it down and found that my Corsair Vengeance LPX DDR4 3200MHz was jumping between 16-18-18-38 timings during heavy asset streaming, causing a 4-7ms offset between the output signal and the refresh rate. I tried enabling V-Sync in-game first, but input lag shot up to 70ms—it felt like I was dragging my mouse through mud. Not an option. I went into the BIOS and manually locked the primary timings to 16-16-16-36 and enabled Fast Sync in the NVIDIA control panel. The tearing vanished completely, and input lag dropped to a crisp 18-24ms. I actually noticed some slight jitter even after locking 3200MHz, until I bumped the voltage from 1.2V to 1.35V for a perfect balance. VRM temps stayed between 45-52℃. Signal analysis tools confirm the waveform is finally aligned, with RAM temps sitting at 42-48℃.
