How to stop Corsair Vengeance RGB DDR5 6400 crashes in Witcher?
Right in the middle of casting a big spell, the game would just crash to desktop. It's incredibly annoying when you're trying to get immersed. Under heavy load, my Corsair Vengeance RGB DDR5 6400 was hitting 62-68,C, which caused some bit-flips and triggered the system's memory protection. I tried increasing the virtual memory first, but that did absolutely nothing, which made me realize I needed a hardware-level fix. I went into the BIOS and clocked the RAM down from 6400MHz to 6200MHz and bumped the voltage from 1,35V to 1,38V to stabilize the signal. I ran OCCT for two hours and didn't see a single error, and the crashes stopped entirely. I did notice that loading times increased by about 3 seconds after the downclock, but I fixed that by optimizing the tRFC parameter in the XMP profile. RAM temps now stay between 55-61,C, and frame times are steady at 8,2-10,1ms.
