GPU sensors going blank/gray

Not exactly sure when this started happening, but the GPU clock information will occcasionally go blank for a split second on the main window, and all clock information goes gray on the sensor window. When the values return, the "GPU" text remains gray. Almost looks like the GPU is disabled afterwards.

Sensor Window

I know this seems like a pretty harmless issue to point out, but the same thing happened to the VRM sensor reading on my previous motherboard that died a few days later. Just wondering if any of this could be related to a hardware issue, because I've been getting some odd nvlddmkm driver crashes recently. The card also randomly throttled itself to idle clocks for the first time yesterday even though I was within thermal limits.

Here are my PC specs:

Grey values in sensors window mean HWiNFO is unable to read a valid value from the sensor. In case of GPUs this usually means it's in a "sleeping" state with clock gated.

I see. It seems to happen at completley random times though. Is it normal for a GPU to enter this sleep state while under load?

Under load it's not normal, so it might rather be an issue in GPU drivers. Try to update them.

Did that yesterday. Ran DDU and then installed 512.77.
Think I figured out what's causing it. If I have both the "Sensor Status" and "System Summary" windows open, the grey text/blank values issue will occur. If I only have one of the windows open, it doesn't happen. Tested it for a few hours to make sure. Maybe it's a polling problem?

Thanks for your observation. Indeed, this could be an issue if both summary and sensors windows are active. Let me have a look at this and see how to fix it.
