God of War Ragnarok PC DLC keeps crashing during large scene transitions. Should I lock the PCIe speed?

Every time I entered a major combat zone, the game would just vanish to desktop without a single error code. It was incredibly stressful. The PCIe 4.0 link on the Kioxia EXCERIA PRO 2TB has this annoying dynamic power saving that causes voltage to swing between 0.8V and 1.1V, triggering a hardware timeout reset. I wasted time updating GPU drivers first, which actually made the crashes more frequent—I was honestly ready to toss the drive. I finally went into the BIOS, forced the PCIe slot to Gen4 instead of 'Auto,' and bumped the chipset voltage to 1.15V. In AIDA64 stress tests, the random read latency locked in at 42-48ns, and the crashes stopped completely. The only downside was that my boot time increased by about 3 seconds until I disabled CSM mode. The SSD runs at 48-58℃ and the heatsink stays at 35-42℃. After ten hours of straight gaming, the response is crisp and the input lag is gone.
