Why does Corsair Vengeance DDR5 96GB crash in The Witcher 3?
The game would just vanish to the desktop after two hours without any warning, and the unpredictability of it was honestly stressing me out. I noticed that the Corsair Vengeance DDR5 6000MHz 96GB kit, specifically due to the electrical quirks of these 48GB modules, had VDD voltage fluctuations of 15-25mV when handling the massive open-world data of the Next-Gen update. I tried enabling Low Latency Mode in the drivers, but while the mouse felt a bit snappier, the crashes didn't stop, which felt like a slap in the face. I ended up going into the BIOS, manually overriding the memory voltage from 1.35V to 1.40V and locking the VDDQ at 1.35V. In OCCT memory stress tests, the error rate plummeted from 12 per hour to zero. The only catch was that the sticks spiked to 62℃, so I had to rig up a tiny 40mm fan to bring them back down to 52-56℃. CPU temps stayed around 70-76℃ with the clock locked at 6000MHz. After six hours of gameplay, no more crashes, and the input response feels incredibly tight now.
