Fine-Tuning Voltage and Timings for Samsung 9100 PRO Overclocking
Based on geek log #OC-2026-22 for the Samsung 9100 PRO PCIe 5.0 8TB, the ray tracing workload was causing glitchy timing jitters. Frame intervals were swinging between 26ms and 32ms, with annoying peaks hitting 48ms. I initially tried loosening the timings, but the system just crashed immediately. The goldilocks zone was found in the BIOS under Advanced Voltage Settings: I set the voltage offset to -0.050V while forcing the heatsink fan to 100% duty cycle. I monitored the heat using HWinfo64, and it stayed rock steady inside a 52-58℃ window. The performance gains were verified within a 2% margin of the theoretical limit. However, it's not absolutely perfect. Whenever the particle effects get too insane in the metro stations, I still see some very faint flickering. It's not a crash, but it's just the reality of dealing with PCIe 5.0's EMI at these clocks. No matter how you tune the voltage, a tiny bit of electronic noise is simply inevitable.
