How to fix frame generation spikes on Corsair Vengeance DDR5?
That silky-smooth city traversal is finally back. Once I switched to Gear 2 mode, the pressure on the memory controller for my Corsair Vengeance RGB DDR5 6400 just evaporated. My frame time went from a chaotic 18-35ms swing to a tight, stable 12-15ms window. I'll admit, I was stubborn at first, trying to push 6400MHz in Gear 1, but that just led to constant sync errors when loading massive building models. The screen would flicker every few seconds—a classic case of chasing clock speeds and sacrificing stability. I went back into the BIOS, flipped the switch to Gear 2, loosened tREFI to 65535, and set the voltage to 1.40V. Looking at the RTSS frame time graph, those jagged peaks were completely flattened. I did notice my CPU temps climbed about 4℃ after the switch, but that's a tiny price to pay for this level of fluidity. RAM temps are sitting at 54-60℃ with VRAM usage around 11.5-13.2GB. The physical response of the controller now feels instant and incredibly snappy.
