Is undervolting fixed now? Remember Optimum Tech saying it didn't work in the early days.

Only that it was very early days and he was proven wrong spectacularly, I used a combo of undervolt and power reduction and it worked v well on my 4090.

Interesting, will have to look into it as the 80% power limit has served me well on my 4080 but who doesn't want free performance ey

No one overclocking? I just turn my power limit up and raise the core offset?

Probably not, if your current BIOS has a power limit you are happy with you'll be better undervolting. These BIOS are more about pushing power limit to the likes of 500w+ and in terms of the one I'm using, upping the voltage cap to 1.19v.
For example, due to the UK's really cold weather setting in I finally managed to break 20k with my 4080 and a 5950x in Port Royal
I scored 20 023 in Port Royal

This is pushing 3120mhz at 1.135v and a power draw of up to 550w. So, the BIOS is mostly about pushing benchmarks but in the likes of Cyberpunk with everything cranked up to max you will get some extra frames with this kind of overclock. It's horrendously ineffecient on your electricity bills though

Makes sense now that I think about it.

Just an update:
When I check the power usage when uv+pl it does seem that when uv the pl often breaks through the limit.
So for example I'm limited to 80 % but often in the msi graph the power will be between 85-90 with the temps reflecting that usage.
Does yours do the same?
