Turn off Load Line Saturation Control and change the Load Line Calibration to Mode 4 (Middle).
Next attempt to remedy the problem was to change the PWM Switching Frequency to 1000 KHz. This did not work out well because now during CPU idle, the voltage looked a bit high. Workaround to this problem was to raise the CPU voltage to accommodate the droop during load. Not a big deal until the CPU is in need of that last bit of power. Right from the start the issues started, the Vcore droop was 0.05 V. Next step was to reach the end-goal of 5.8 GHz with a maximum voltage of 1.4. This is where the stock CPU turbo sticks to when all cores are in use. The first step here for an all-core overclock was going straight to 5.5 GHz (P-Cores) using only 1.25 V. Often undervolting and picking 2-cores for highest frequency will yield better results for power efficiency, but is it quite the undertaking to validate on each and every motherboard tested. Once done, it was time for the brute all-core overclock, simply because it is the easiest when constrained by time. Using the same principle rules from the 12th generation Intel processors as a guide, the session started off the same with a baseline test at stock configuration to get the basics out of the way. Overclocking - Didn't go as planned.Overclocking the Intel 13900K CPU had a troublesome start this time.
