How to stop Samsung 9100 PRO from crashing in Lost Ark?
Getting a black screen while loading into a busy port is an absolute nightmare, especially during group raids. After digging into the logs, I found the Samsung 9100 PRO's PCIe 5.0 interface pulls massive power during peak R/W, causing a 0.1V instantaneous voltage drop at the M.2 slot, which triggers the SSD's internal protection. I first tried cranking my virtual memory to 64GB, but while it eased the RAM pressure, the random crashes didn't stop—it felt like I was fighting a losing battle. I then went into the BIOS Advanced Power Management and switched PCIe Link State Power Management from 'Auto' to 'Disabled,' and added a 0.02V offset to the M.2 slot voltage. Monitoring with HWMonitor showed the voltage stabilize from a wild 3.1-3.4V swing to a flat 3.3V line. My idle temps jumped by 5℃ at first, but I fixed that by ramping my chassis fans to 1500 RPM, keeping it around 48-52℃. Read speeds are now locked above 10000MB/s. Ran an OCCT storage stress test with zero errors; the power delivery issue is finally dead.
