Title: Mhash rate lower when in display power saving? Post by: overflowing on August 14, 2011, 09:01:26 AM Using Windows 7 with GUIMiner. I've set most of my power saving options to sleep "never". However I still have "Turn off the display" set to 20 minutes and my computer also goes into locked mode. When I wake up the display and immediately look at GUIMiner it shows the Mhash rate as around or below 200 Mhash/s. Then within a few seconds it goes back up to it's normal 240 Mhash/s, where it stays if I am using my computer.
So now I'm wondering if I'm not getting my full hash rate when I leave my computer running and I'm not actively using it. Are there some specific settings I should have in windows & power options or elsewhere to ensure I'm getting my full hash rate? Is there a way to know what your hash rate is when your display is off?

Normal hash rate is 120Mh/s, but when it turns of the display it drops to 60Mh/s. I tried changing all power settings to use always best performance but it didn't help.
I ended up with a workaround with - very dark screen dim (instead of turning off) and changing the close lid setting to not go to sleep (it will turn of screen without a hash rate loss). I also would appreciate if If someone could point to the right way to deal with this thing. Title: Re: Mhash rate lower when in display power saving? Post by: mikethebodacious on August 15, 2011, 09:57:46 AM Are you using Phoenix Miner with high aggression? Anytime you open or move around windows your hash rate will be lowered. You're better off putting your power-saving profile to high performance and turning every option to Never, including your monitor sleep time. Lock on wake-up is just annoying and will definitely slow your hash rate using high aggression with Phoenix miner.
