wrong GPU working - Githubissues

I have two GPUs, one Intel HD for display and one NVIDIA Geforce for high performance. When launching the miner, only the weakest one (Intel) works and I did not find a way to make the miner use the Geforce card.

Is there any way to configure which card to attach to the mining process?

same issue here. it should use the nVidia GPU. this should at minimum be configurable

Could you please paste your debug.log from %appdata%\vertcoin-ocm

The One Click Miner will try to use all GPUs by default and there is no way to change that. There is an enhancement label here: https://github.com/vertcoin-project/one-click-miner-vnext/issues/128#issuecomment-774773200 to disable integrated graphics (Intel HD) which may solve this problem.

I also noticed that Task Manager shows my Intel GPU at 100% and my NVIDIA GPU at 0%. But in the logs, I see that the miner did detect both GPUs and mentioned configuring 1 CL and 1 CUDA worker. If cl_device(0) and cu_device(1) in the logs correspond to my GPU 0 and GPU 1, then it would seem that both GPUs are being used. Could it be that Task Manager simply isn't showing the NVIDIA usage for some reason? Below are relevant parts of the log:

that's what I'm seeing in my log as well, it does seem to be using both GPUs, but Task Manager only shows usage on the integrated GPU for some reason.

Here are my logs. I have exactly the same behavior as @ironcladmerc and @descawed: The task manager says that only the intel card is working.

There is an enhancement label here: #128 (comment) to disable integrated graphics (Intel HD) which may solve this problem.

Thanks, I will look into that

I see hashrate from both cl_device(0) and cu_device(1). They seem to both be working.

I've done some more research and this appears to just be an issue with how Task Manager displays CUDA usage. For me, when viewing a GPU in Task Manager, it displays 4 charts at the top - 3D, Copy, Video Encode, and Video Decode. It turns out these are just 4 options of a couple dozen different things you can have it display. If I click the text above the chart that says (for example) "3D", one of the options in the dropdown is Cuda, and if I choose that I do see 100% on my NVIDIA GPU. So I believe there's no issue with the miner, we've just been fooled by the perhaps unintuitive behavior of Task Manager.

OK thanks you all for your investigation! I will then close this issue as both GPUs seems to be working correctly.

Sorry, I have the same issue on my ubuntu 22.04 OS. I updated my vertcoin ocm just a week ago. For some reason, it works well when I run on an extended screen using --verbose argument
