Title: How to understand GPU power usage? Post by: antonio2234 on July 07, 2017, 07:51:10 AM Hi,
I am running 5x1070 and overclocked by "MSI After Burner". I want to know if there is any way to check power usage for each card? Title: Re: How to understand GPU power usage? Post by: iamnewhere on July 07, 2017, 07:55:21 AM Open a command line with (Windows Key + R > cmd > enter) and go to "C:\Program Files\ NVIDIA Corporation\NVSMI" and type in "nvidia-smi.exe" - you get the current power usage in W and the current TDP in W :)

best solution is wall meter cost like 10$ Title: Re: How to understand GPU power usage? Post by: antonio2234 on July 07, 2017, 04:58:25 PM This is my results after overclocking.
http://i64.tinypic.com/2wn9zic.jpg Per this screen, my power usage is 138-147w, right? Whats 184w mean then? "Volatile GPU-Until": 98-99% => Is it ok or too much? Title: Re: How to understand GPU power usage? Post by: iamnewhere on July 08, 2017, 01:50:48 AM 99% usage is normal if you are mining ;)
the 184 is your TDP limit (if you didn't change it from 100% in Afterburner than this is the real TDP of your card). depends from what you mine you can optimize your settings now in Afterburner.

My power setting in Afterburner is 85%, not 100! Title: Re: How to understand GPU power usage? Post by: Apneal on July 08, 2017, 06:18:40 AM GPU utilization is not power draw. Also you cant set "85%" power in MSI, you can adjust the power limit or the core voltage. "85% power" means nothing to anyone. Further, reported wattages are generally about 50W less than actual wattage at full load, maybe because it doesn't report PCIe draw.

My power setting in Afterburner is 85%, not 100! So you have ~ 215W TDP, due to your setting down to 85% you are at 184 TDP but you are even not close to that limit. And the values from that program seem to be correct as if i take ~ 50W for the rest of the computer + adding all values there from my GPU's im close to the W i take from wall - the few W on top are the normal loss through efficiency of PSU. |
