Why does Starfield keep crashing with an instruction set conflict when entering main cities using ADATA DDR5 4800?

Launching this game feels like a stress test for my entire PC; every time I hit the main city, it just CTDs to desktop. It's a joke. The ADATA DDR5 4800 was hitting a sync deviation of 2.1-3.2ms while handling Starfield's massive data streams, which triggered a protective restart by the memory controller. I tried lowering the resolution, but that just made the game look like a pixelated mess without fixing the crashes—complete waste of effort. I ended up flashing the latest Beta BIOS from my motherboard vendor and manually bumped the memory voltage from 1.1V to 1.2V. After running MemTest86, the errors dropped from 5 per hour to zero, and my playtime went from 10 minutes to 3 hours straight. I almost had a heart attack when the power flickered during the BIOS update and the board went into recovery mode, but I managed to re-flash it. Temps are stable at 40-46℃. I exported the crash stacks via system logs to confirm the fix, and everything looks clean now.
