No power for nvidia gpu (it has worked for a while)

[ikorbln]

Hello, i think after a couple driver updates from nvidia i did not get any power readings anymore for the gpu. I the logfile there are all sorts of readings for load/clock but no power.

I use the latest version 0.16. Nvidia is 460.89 / RTX3070

Can you check if %windir%/system32/nvml.dll exists

Is the power readings present if you run the latest version of LibreHardwareMonitor (at the time of writing)?

[ikorbln]

The dll is not in this directory and with the Libre there is no power reading for gpu.

[nickbabcock]

Hmm I would recommend reinstalling nvidia geforce or compiling nvml via some other means and placing it in that directory or alongside the ohmgraphite executable.

[ikorbln]

ok, after reinstalling the driver the nvml.dll is now in the folder but the Libre did not show the power.

I'd next try restarting and then copying the nvml.dll to the same folder as Libre / OhmGraphite

[ikorbln]

sorry, no success. Last day i saw the gpu power in the ohmgraphite_log was the 8 Dec.

I wonder what happened on December 8th.

New user of your exporter and I'm also experiencing this.

Running v.0.16 of Ohm v.0.8.6 of libre. Nvidia driver: 460.89

The power usage is not reported in either Ohm or Libre.

Good find. Looks like we may have to wait for nvidia to push this fix or have users download their hotfix

Fixed in the latest nvidia driver update. After updating, restart ohmgraphite.
