My game keeps crashing to desktop whenever I load into large combat zones with a Samsung 9100 PRO. Is this a PCIe issue?

Every time I hit a major battle area, the game just vanishes. No error code, just a crash to desktop. It was incredibly frustrating. The Samsung 9100 PRO 4TB uses a PCIe 5.0 link that, on some boards, suffers from aggressive power saving, causing the controller voltage to bounce between 0.9V and 1.2V. This triggers a hardware timeout. I tried updating the BIOS first, but the crashes actually got worse, which almost made me rip the drive out of the board. I eventually went into the BIOS, forced the PCIe slot to Gen5 instead of 'Auto', and bumped the chipset voltage to 1.18V. In AIDA64, my random read latency stabilized at 38-44ns, and the crashes stopped completely. One annoying side effect was that my boot time increased by about 4 seconds until I disabled the CSM compatibility mode. SSD temps are running hot at 55-68℃, but the heatsink is fine at 38-45℃. After 10 hours of testing, frame times are rock solid at 5.1-6.4ms.
