Stopping Samsung 9100 PRO PCIe 5.0 crashes in Battlefield V
This drive is blindingly fast, but the fact that it can literally reboot my entire rig while playing Battlefield V is just ridiculous. With PCIe 5.0's massive bandwidth, the Samsung 9100 PRO controller spikes to over 14W within 1.2 - 1.5ms during peak reads, triggering the motherboard's overcurrent protection. It's like the PC is playing a prank on me. I tried disabling Fast Startup, but that did absolutely nothing for the crash frequency. I finally went into the BIOS and forced the PCIe link speed down to Gen4 and disabled NVMe power management. Using a power analyzer, I saw the peaks flatten out to 8 - 11W, and the reboots stopped instantly. Sure, sequential reads dropped from 12GB/s to 7GB/s, but the load time only increased by about a second, which is a trade-off I'll take any day. Drive temps are now 55 - 65℃ with the fan at 2000 RPM. Exported all crash timestamps to the log for peace of mind.
