Seems like even a SOC Voltage of 1.025@1800 FCLK is stable on my system.
That is also the default voltage when running stock FCLK (1200).
I also used the other default voltages IOD/CCD 0.9504 and VDDP 0.9002
Can someone explain why there is a 0.0030 Voltage Drop when using:
VDDP: 0.900 -> ~0.8970
IOD/CCD: 0.9500 -> ~ 0.9470
I don't remember the exact numbers, but something around that.
Why do I have to set the voltage 0.0001 - 0.0002 higher to avoid this Voltage Drop?
And is running PBO with a scalar of 1x actually the same as the basic overclock?
Is this the reason no one actually sees a difference in performance?

In some cases, the results can be improved even further, by increasing the "Precision Boost Overdrive Scalar" value from the default 1x setting. This option directly affects the silicon reliability and because of that, it should be only increased from the stock if the performance improvements justify it (which they frankly, seldom do). Personally, I would never increase it to higher than 4x. The current level can be checked with HWiNFO (Central Processors >> CPU PBO Scalar (Reliability Reduction)).
