I think is not possible, you have to play with the core if you want to decrease Mhs or if you want to protect Temp use the last functionality implemented
For what do you use the -I parameter?.
almost all miners have switch I or intension, so I can limit hashrate if maximum is 50Mh/s than I can limit to 10Mh/s
so I can still use my PC for mining and writing in word
You can use easy trick... Memory speed reduction that will make the GPU core Will be more free for other works. In my case with a 5700, I can make home Office mining without any problem. I have It only límited the core yo mine at proper voltage. When you are out of the mining screen it automatically reduces the Mhs..
where I can do that?
