    Having trouble moving from Manual Voltage to Adaptive Voltage

    Hi everyone

    First let me say that I am not an experienced overclocker by any means, I only have experience doing basic overclocking with manual voltage. Please don't crucify me if I misunderstand something or make a mistake.

    With that out the way, I have a Maximus X Hero Z370 motherboard and I am currently running my 8700k at 4.8Ghz with a manual Vcore of 1.275V in BIOS (1.264V read by AIDA64, CPUID, AI suite etc) and LLC level 6. DRAM is just set to XMP 3200mhz (G.Skill Trident Z RGB 16GB). The system is stable during AIDA64 FPU stress test and can complete a Realbench stress test without error. The core voltage reading stays at 1.264V in all situations.

    I have read other threads on this forum that say it's not ideal to be on LLC level 6 and full voltage all the time so I am trying to change to adaptive voltage. I have followed this guide in an attempt to do so:

    I understand the guide is for Kaby Lake CPUs but I am led to believe that the process remains the same for Coffee Lake and the BIOS UI is more or less the same.

    The issue I am having is that after following the instructions in the guide, when i run AIDA64 FPU stress test to test stability, the core voltage continually drops and the CPU clock speed drops with it. The voltage will start at 1.264 and after starting the test it will gradually reduce all the way down to 1.00V and the clock speed to 4Ghz before I cancel the test.

    I have included some screenshots of my BIOS settings that I used, please let me know if I have missed any important information and I will do my best to provide it. Any help would be appreciated. For now I have just reverted to my manual voltage settings.
