How to fix Corsair Vengeance RGB DDR5 6400 bandwidth in GTA VI?
The moment I hit the neon-lit streets, my frame rate turned into a slideshow. It was almost funny how bad it was. I checked my specs and realized my Corsair Vengeance RGB DDR5 6400 was running in single-channel mode because I'd used the wrong slots, cutting my bandwidth down to a pathetic 26-30GB/s. I spent an hour updating my GPU drivers three times thinking that was the issue, but the FPS was still jumping wildly between 42-115 FPS—what a complete waste of time. I reseated the sticks into the correct slots to enable dual-channel and locked the frequency at 6400MHz. CPU-Z showed bandwidth instantly soaring to 54-58GB/s, and my 1% lows jumped from 35 FPS to 72 FPS. I actually failed to boot the first time I tried moving them until I actually read the motherboard manual for once. CPU temps sat at 66-72℃. The in-game performance overlay now shows a perfectly flat frame time line, with memory temps stable at 48-54℃.
