Title: BFGMiner how to setup to 40% POWER of GPU
Post by: eskaer on October 09, 2013, 02:45:23 PM
Hello this is my first post so i want to say Hello :)

Im looking how to setup (what parametr to start bfgminer) Bfgminer to work on 40% power of GPU
When i use this: bfgminer.exe -u x -p x - o x  and run it it works fine but on 100% power my GPU.
I dont know how to run it on 40% for more silent in night. Reduce gpu fan speed but i don't want to overheat it.

Thanks for reply.

You're probably looking for Intensity (-I) which is a value of -10 to 14 (or 0 to 20 for scrypt) that sets the aggression level for mining. You can also set the intensity to D which will set aggression dynamically to ensure you can still use the computer while mining (without lag). The lower the intensity, the lower the hashrate and temps (and therefore fan speed). (I would not suggest using -I D for scrypt mining, your hashrate will drop down to very very low numbers).

If you're using Windows, you can also use CGWatcher (http://cgwatcher.com) to lower or raise intensity at certain times, intervals,  when the computer is idle, etc.
