[Feature Request] Read out Power consumption from GPU

Open mrsieb opened this issue 9 months ago • 2 comments

@Rem0o Yes, I do. As you explained before (and I have now understood) you are correct in that it works as intended.

For anyone needing a clarification: The card itself has a temperature where goes to 0% fan speed (for my RTX 4070 FE it is below 35°C). This has to be taken into account with the fan speed control graph (or whatever control you use), otherwise you may end up creating an "impossible" scenario. The goal here is to figure out at what temp your card goes to 0%, and make the graph align with that (set the percentage to 0% below that temp, to whatever you want above that temp). Once your card has started spinning its fans, it will not go to 0% if you tell it to, only when it is below its trigger temperature.

Well i figured out that's not exact the case, I mean the Temperature goes down in this circumstance but the related values is how much Power the card is using. And this is related to GPU Clock and VRAM Clock. My 4090 goes to 0 RPM with 42° degrees as well. Power have to be below 50W. (at least on the 4090) for this GPU Clock and VRAM Clock have to be under 800Mhz. Afterwards the card cools down as well.

Two things i struggle a lot was different Hz on different Monitors one on 144Hz one on 120Hz. since both are running with 120 no issues any more even on 4k both on 144Hz as well. If the refresh rate is different on the screen the VRAM Glock goes not under 10kMhz. (so make sure to set same refresh rate on both monitors if you have) And last but not least i had to remove all Nvidia Drivers with DUU Tool from Guru 3D and reinstall fresh. (Don't know which setting was preventing the mode and no it was not powermanagment mode this was set to normal before) Any way this is a nice IDLE State:

long story short it makes no sense that the Temperature is the trigger point for RPM control at all because i can run the card below 40° and Fan would go on and off the whole time.... even when its takes 200W so in this case Power would make more sense to have in FanControl Image

and any way my personal opinion is its completely stupid that 30% is a hard limit from Nvidia, I even would prefer constantly ~300RPM and ramp it up, instead of 0 to 1200RPM minimum...

We agree on that point!

Power as a source is not planned for the software. I can see the appeal, but I can't justify it right now.
