Crucial DDR5 4800 keeps throwing memory parity errors and crashing FH5 during high-speed driving. Fix?

Every time I pushed the car over 300 km/h, the game would just vanish and dump me back to the desktop without any warning. That kind of unpredictable crashing is incredibly stressful. The Crucial DDR5 4800 defaults to around 1.1V, but during intense read/write cycles, I spotted momentary voltage drops of 0.05V, which triggered the memory controller's parity errors. I started by updating my GPU drivers, but the crash frequency didn't budge—that kind of blind troubleshooting is just frustrating. I then went into the BIOS Advanced Memory settings, manually bumped the voltage to 1.2V, and killed the motherboard's auto-power saving mode. In five consecutive rounds of MemTest86, the error count dropped from 12 to zero, and my playtime went from 15 minutes to 4 hours without a single crash. I actually tried pushing it to 1.3V at first, but the RAM temps spiked to 62℃, triggering a thermal shutdown until I dialed it back to 1.2V. Now, RAM temps are steady at 42-48℃ and the chipset is at 50-55℃. The in-game performance analyzer confirms the read/write is rock solid now.
