How does voltage compensation stop frequency diving lag?
Frequency diving is almost always a voltage compensation issue. Analyzing the curve, I found the memory clock jumping plus or minus 150MHz around the 6000MHz mark. I hit the BIOS, went to Advanced Voltage Control, and nudged the DRAM voltage from 1.35V up to 1.42V while locking the SoC voltage at 1.2V. Per report BG3-BOLT-X, the frequency sway shrunk to plus or minus 40MHz, and the framerate settled between 64 FPS and 69 FPS. I made a BIOS profile backup just in case. While performance is way up, memory temps hit 72℃ during OCCT tests, meaning if your airflow is garbage, you are looking at a thermal shutdown during long sessions.
