I'm using XMP and PBO enabled. I encountered an issue when setting the voltage to 3200MHz on a 1.15V SoC. At 1.1V I reached around 3533MHz, but it became unstable beyond that. Going lower to 1.05V allowed me to reach 3733MHz, though it was unstable and crashed quickly. At 1.075V it worked but remained unstable. For the Patriot Steel Viper 3733MHz RAM, I need a stable frequency between 3400-3600MHz. They use Hynix C-die modules with VDDG between 950mV and 1050mV, VDDP around 1050mV, and DRAM voltage set at 1.35V for stability. My SoC voltage was key, and with PBO enabled it seems higher voltages won't help past 3200MHz. I could try increasing the SoC voltage, but beyond that stability drops.
