Was watching this video how undervolting a 4090 = less performance. Link: [https://youtu.be/XrZNSTmOstI?si=9Wn14Zrv6mvp-ES4](https://youtu.be/XrZNSTmOstI?si=9Wn14Zrv6mvp-ES4)

Not sure if this is only for 4090 or other 40 series cards.
​
Whats your guys’ thoughts here? Comments seem to suggest he was undervolting incorrectly

Power limit works great but you can squeeze out a little more with an undervolt less power/higher clock. The previous gen GPUs did something similar with having a separate video clock it’s just more pronounced on the 40 series. I’ve undervolted my 4090 just fine.
I’v undervolted a 4080 very successfully
No performance changes
my 4080 happily runs at 2780mhz @975mV and +1700 on the memory while performing 5% better then stock and drawing nearly 80W less in power. So dunno
