High idle power draw RTX 2070 Super

Hey, when idle the power draw is about 55w which seems very high. I’m using a dual 1080p 144hz monitor setup, with one of the monitors reporting as 143.61hz which also has g-sync. The “PowerMizer” in nvidia-settings seems to be stuck at level 4 which is probably what is causing this.

However, when I set both monitors to 60hz the power draw gets reduced to 37w and the “PowerMizer” goes back down to level 0, but 37w still seems high when idling.

The high power draw is causing the fans to constantly spin up to high speeds and then shut off again, which is annoying the hell out of me.

Is this a bug? am I doing something wrong?

nvidia-bug-report.log.gz (380.0 KB)

This looks like a bug.

I can confirm this as well.

I also have the 2070 Super.

If I set any of my monitors (I have 2) to 144hz the power level will not drop below 4. If I disable the secondary monitor the power level will drop normally with the primary on 144hz but will remain on level 4 if that second monitor is connected even at 60hz.

If I turn my monitors to both 60hz refresh then my power level also drops normally.

In effect I can completely verify the OP’s issue with the added test of turning off one monitor.

This seems to be a regression as I remember a similar issue a while back (maybe drivers 395?) where if you had both monitors set at 144hz the power level would stay at 4 but if you turned the secondary to 60hz the power levels would drop as normal under light loads.

I am using a more recent driver that the OP so the issue has not been resolved with the newer driver.

I am using Arch and an using the drivers from the Arch repos. Linux kernel 5.13.13-arch1-1

this is nvidia-smi under no load, just the desktop and a few app running but nothing that would not normally have the power level dropping down to 1

The power level should be at one and the temp should then drop to about 30-40C. With the power level stuck at 4 the temp stays at around 50C under the same conditions. The fans do work as they should when the temp rises a bit but the card should not be maintaining this temp unless I have a game or other graphically demanding program running

Are the devs currently working on a fix so that the next update may include a fix for this issue and if so do we have an eta and driver version of the potential fix?
