Title: 7970 Idles to half speed.. Post by: silverbox on July 28, 2012, 10:58:22 AM after about 4 hours of no keyboard/mouse usage, with moniter powered off (by win7).
Win7, cgminer. The moniter is plugged into the 7970. Any thoughts? I changed the power settings to High performance and doubled checked/PCI Express/Link state setting=Off. This didn't fix it :( -autofan and -autogpu are turned on in cgminer. As soon as I wiggle the mouse, moniter comes to life, the card speeds up again to ~650ish from the sluggish 300 or so its idling at.. Title: Re: 7970 Idles to half speed.. Post by: DOH! on July 29, 2012, 04:15:56 AM What program are you using to overclock? I know I had fits with anything but msi afterburner and diablominer. I have 4 7970's pulling 2830mhash/sec. Another thought, make sure that there is something non-static going on on the screen.

Another thought, make sure that there is something non-static going on on the screen. cgminer to overclock with a range set and -autotune on I think I set it at 800-1100. When it idles down cgminer hasn't lowered the clockspeed. I guess I could set it at 1100 flat just to be sure. Another thought, make sure that there is something non-static going on on the screen. Yeah I thought about that too. Setting windows to never turn the moniter off and turning a screen saver on, and seeing if that stopped the idling problem. That box has a beast of a ancient tube moniter (19" flat screen) on it thu, it probably sucks down 100+ watts ;), I'd rather have it off if I'm not using it. Title: Re: 7970 Idles to half speed..

Might want to look into headless stuff, or dummy plug the secondary output and shut off the monitor. |
