Mining Eth in Win10; Can I disable a GPU to game, mine with the others?

[Quadwinner]

Hi,

Currently I´m mining ETH with an Ubuntu-based OS on a USB-stick, plugged in my Gaming PC.
Works great, but it means I have to stop mining and reboot into Win10 when I want to play games, or use the PC at all, really.

Is there any possible way to use a miner in Windows 10, and when I want to; disable the just the main GPU and use it for gaming, while the other GPUs in my PC continue mining?
Something like just edit a config file, save/relaunch the miner and then use the main GPU+PC for gaming/other stuff? Or would the system be to sluggish?

And what is the best miner (eth) in Windows 10? Got bad Hashrate with my 980ti´s, the Ubuntu based OS worked better, but then again was an even bigger mining-noob back then, So I´m willing to try windows again.

Thanks!

You can - there's a command within the miner software (usually -di) that allows you to specify which GPUs should be enabled/disabled for mining.

Now, it should hence work fine in theory, in practice, who knows. Haven't tried it myself.

I'm wondering this as well. Any help would be appreciated.

i think you can set in config of claymore, read readme.txt to config 5 gpu mining, 1 gpu in pci-ex x16 for game....

Absolutely you can do it with some command in your miner. You can arrange how many GPU used in your miner software. Google the command according what miner software do you used.

Thanks, I will look into this soon, although not at this very moment due to refurbishing my apartment.
Will post here If/How I got it to work

As a plan B, would it be possible to run the ubuntu-OS in some form of virtualmachine/virtualbox? I got a lot better hashrate in the ubuntu OS (well, with my old gpu’s anyway) than in Windows the first time I tried, don’t wanna sacrifice hashrate.

UPDATE: YES, I can! 

I tried Genoil first but couldn´t find anything on this topic, so switched to Claymore (10), no problem what so ever!
Just start mining, then type a number to disable/enable that specific GPU in runtime, for me this is "0" as I want to game with that GPU (just type a number, not the "").
I guess if I relaunch the miner it will enable all GPUs, unless you use commandline -di.

-di GPU indexes, default is all available GPUs. For example, if you have four GPUs “-di 02” will enable only first and third GPUs (#0 and #2). You can also turn on/off cards in runtime with “0”…”9″ keys and check current statistics with “s” key.

I will say however; I have 2 cards in SLI, so in order to game I have to go into Nvidia control panel and disable SLI, to do that it requires me to exit apps - among others the miner - to change that config. And the same if I want to re-enable SLI for gaming.

So I guess I might remove the SLI bridge/leave SLI disabled and game with just the main GPU as long as it has enough performance.
SLI gives FPS boost in some games but not all, anyways (sadly).

I do this all the time, got 4 GPUs mining. But sometime i want to play PUBG, then i just start the .bat file and put in --devices 0 1 2 and skip the 3rd and play on that.
