How do I stop blue screens from memory overclocking in MGSV?

MGSV was crashing with blue screens every few minutes, losing all my progress. I tried pushing the voltage to 1.45V, but it made the instability worse and caused immediate crashes. I needed to back off. I used the GamePP Memory Monitor to adjust the voltage to 1.35V. MemTest86 ran eight rounds with zero errors. HWiNFO confirmed memory temperature at 48-52°C and stable bandwidth at 28.4GB/s. The system is finally reliable.
