During these tests, I relearned how to overclock the DDR5 memory on this Z690 DARK KINGPIN. Starting with the CPU VDDQ setting, it’s about setting the PMIC turbo mode to auto and manually setting the CPU VDDQ. A setting not to be neglected because this voltage is very sensitive on the stability. A setting of 1.35 V to start with is a good starting point.
Next we have the RAM voltage setting, which cannot exceed the 1.435V mark without unlocking the PMIC. The Bios 1.15 of the Z690 Dark now allows this. 
Now we come to the BMI and its limits. During our tests, unlike the DR kit, we were able to touch the VDDQ_CPU and the VDD2. For the latter, a value of 1.3 V was sufficient for 7800 Mt/s CL34 but the 8000 Mt/s Cl32 bar required to raise it to 1.4 V. We also have the option of disabling the Ecore to relieve the BMI and go even higher.
