Negative curve optimizer steps are not improving temperature really. All curve optimizer does in the end is raising clocks on the same voltage.
Here is how it works below in pic
You are lowering the V/F curve from red curve to blue curve. So lowering voltage for any given frequency.
You would think that you are going from point 1 to point 2. Because the voltage is dropping... current (Amperes) is dropping so does power consumption.
Yet because the CPU is set to deliver max performance at any given moment it goes from point 1 to point 3. And this applies to any point on that curve.
So it raises clocks because it can, so current(A) goes up again and power is staying around the same.
Voltage/Frequency curve (V/F)
So it pushes the limits of stability. Doing additional CPU undervolting or adding frequency (+25MHz steps) can throw it easily out of those limits.

I hope providing better cooling system will allow me to use my CPU on default(maximized settings) without any thermal issues until then I will keep using it with disabled PBO and CBS. I noticed another problem - my case fans was connected via daisy chain which in the end got sata cable powered connection and the case itself has 2 reset switch cables- one for the LED and one working for a power sw. 2 days was working fine (the reset button which works as a LED change colour button) and I could change between colours of my fans. 1 day later I decided to remove one out of the 6fans on my pc fans in order to concetrate the airflow in one direction because it was distracting the proper way of the air. And it kept working fine for 1 day+ , now the RGB is lightning in only 1 colour mode and reset switch doesn't work at all..It's working now but only in green colour(I want it in white). There is no software for ARGB controlling at all installed on my pc and never used. Only used that switch button.Fans are working fine , but the RGB is not , can this mean something happened with my fans and any suggestions I can fix this ? BTW I tied all the cables carefully with pig tails in order to do some ''cable management'' and this case fans was a big mess.I could change them with my old pc case fans which are 3pin and have option to daisy chain again but they don't connect its power to SATA but instead to a 3pin connector on the mobo.The problem is that this particular mobo have 2 ports for 3pin fans right in the middle of the mobo which doesn't allow me to do a ''clear build'' without cables hoverin in the middle of the case/build.
