RTX 50 Series UV Question

When undervolting RTX 50 series, any gpu probably, the sustained effective clocks are lower than the nominal clock set in Afterburner. To my understanding the effective clock delta is decided by gpu temps and load scale/type (PT, RT, light load etc)

Questions:

  1. Is it worth it or even possible to tune for a 0 clock delta by tuning to a lower value

  2. Is there a definitive chip specific frequency at which the bulk of the performance is ensured for Blackwell

  3. Is it better to tune for a frequency while under the heaviest possible load and therefore be prepared for the worst case scenario?

My profiles are as follows

Stock 1070mV @ 3150

885mV @ 2820

925mV @ 2917

965mV @ 3022

1005mV @ 3150

1050mV @ 3217

Under heavy pt loads, effective clocks are 50-150mhz lower, with the delta being larger at lower voltages
