Question RTX3080 draws 115W at idle

[Eddaz]

Hi,

My RTX3080 draws 115W at idle (measured with HWiNFO64). It should be in the 20-27W range.
GPU load is at 0%. How can this be? What do I do?

My CPU (ryzen 3600) draws 22W at idle which is normal.
Total pc draw at idle is 180W (measured with a voltmeter).

PSU is rated 750W and is on the older side, 5-6yo.

My electricity bill is killing me, please help.

Are you using a multi monitor setup?

I agree it should be lower, my 3080 is idling at about 20-22W.

However this is going to make little difference to electric bill. You are using an extra 100whr, so 10hrs to use 1KWhr with an approx price of 50p per KW.

No, single, except it's not a monitor but a TV, which probably makes no difference.

I had read that certain multi monitor setups can cause the gpu to run at max frequency. I see no reason why a TV would make any difference.

Does the clock speed, voltage, and temperature correspond to the power usage? That is, are they much higher than they should be? If no, then the sensor could be off.

Also, what TV are you outputting to?

I don't think so.

GPU clock is at 1800MHz
GPU Memory clock at 2375MHz
GPU video clock at 1590MHz
GPU effective clock at 1800MHz
GPU Core voltage at 0.906V

My thinking is that if the sensor was off, then the voltmeter would not reach 180W.

It's a 4k Samsung but I'm running it at 2560p 120Hz. Model QE55Q6FNA (Europe)

Those are not idle clocks, something is causing the GPU to run at higher than base speeds. Do you have anything running in the background at the moment?

For example, my 3080 ti is at 210Mhz on the GPU clock and 405Mhz on the Memory clock at idle at this moment.

I will agree with the above poster, sometimes high refresh, high resolution monitors can cause the GPU to run at higher frequencies. I just dealt with this on my new Samsung Odyssey G9.

Try decreasing your monitor refresh rate to 60Hz and see if that changes the GPU usage.

Decreased to 1080p at 60Hz and it had no effect.

It's somehow all good now after a random restart. I've restarted number of times before and the problem persisted so I have now idea what happened.
