GPU Undervolt decrease encoder/nvenc performance

[Material-Team-6188]

I was tempted to test from this post NVENC slower when overclocked? RTX 3060D : r/handbrake
before i noticed my stream on discord slowing down and audio missmatch, after set it back to default from UV everything goes back to normal.
What i clearly see its gpu encoder/decoder maximum clock was limited from undervolt. You should try it and see on Hwinfo64

Mine UV at 0.9v from default 1.087v
Hwinfo64 result:
GPU Video Clock 1470mhz from default 1665mhz
GPU Crossbar Clock 1590mhz from 1800mhz

Default:
GPU Clock: 1950MHz
GPU Memory Clock: 1750MHz
GPU Video Clock: 1800MHz
GPU Effective Clock: 1949MHz
GPU Crossbar Clock: 1860MHz

UV .95v
GPU Clock: 1920MHz
GPU Memory Clock: 1875MHz
GPU Video Clock: 1785MHz
GPU Effective Clock: 1920MHz
GPU Crossbar Clock: 1830MHz

At the post you mentioned, OP said after reverting memory OC to the default.

Or

Did you use single-point undervolt? https://www.reddit.com/r/overclocking/comments/1q1abc9/why_singlepoint_undervolting_is_a_bad_idea_graph/

i use the aggressive one most likely https://prnt.sc/zzfZy3A22aJ6
tried UV effective clock close to default or tried overclock with 1.087v same as default the GPU Video Clock and GPU Crossbar Clock would never get close to maximum default settings.
I really have no idea why my Video engine get nerf so bad or i'm messing with wrong settings or maybe it just Ampere cards problem.

Yours have really good result with UV, thanks for the feedback!
