Title: CGMINER: --temp-overheat and --auto-gpu do not work Post by: FreedomCoin on May 24, 2013, 04:28:18 PM I have recently installed a 3rd video card in my ATX case rig, since then the new card and the card below it have been overheating.. Before i put the 3rd card in i could hover around 80-85c without issue. Now im over 95c on two cards with the new setup. See pictures below, the new card is quite wedged in there, there is no more room for anything else. I run my case fans at 100% and the GPU fans kick up to 100% without making much of a difference.
Why is the autogpu and tempoverheat commands not working? I specified the temp-overheat at 90 and i thought the auto-gpu option is suppose to back down timing to lower temps? Code: cgminer --scrypt -o [address] -u [username] -p [password] --thread-concurrency=8000 -w 256 -I 16 --temp-overheat 90 --auto-gpu --auto-fan http://i1341.photobucket.com/albums/o760/FC43/Main%20office%20system/cgmineroutput3gpu_zps68278497.jpg (http://s1341.photobucket.com/user/FC43/media/Main%20office%20system/cgmineroutput3gpu_zps68278497.jpg.html) http://i1341.photobucket.com/albums/o760/FC43/Main%20office%20system/CAM00187_zps8c0732fd.jpg (http://s1341.photobucket.com/user/FC43/media/Main%20office%20system/CAM00187_zps8c0732fd.jpg.html) http://i1341.photobucket.com/albums/o760/FC43/Main%20office%20system/CAM00182_zpsc52300b4.jpg (http://s1341.photobucket.com/user/FC43/media/Main%20office%20system/CAM00182_zpsc52300b4.jpg.html) As you can see i probably have no more than 5mm of space where the middle card is (Powercolor 7790) and the two cards at the top and bottom are 6950s. Title: Re: CGMINER: --temp-overheat and --auto-gpu do not work Post by: FreedomCoin on May 24, 2013, 06:33:01 PM remove --temp-overheat or change it to 85. Add --temp-target=75 or 70 Why you have a crosswire in there? Make sure there is flow in and out of the case. You should be able to run I: 19 keep in mind i am mining LTC... though maybe i should have posted in the alt coin area. Okay i tried changing the parameters to what you suggested and i see no change. One card got up to 96c without lowering the khash output and another one got up to 90c going full throttle at I 16. I figure I 19 is just too extreme if 16 is already running too hot. Here is my new code, as stated it does not seem to change the clocks or khash output at all.. Just speeds up the fans. Code: cgminer --scrypt -o [site] -u [user] -p [pass] --thread-concurrency=8000 -I 16 -w 256 --auto-gpu --auto-fan --temp-target=75 --temp-overheat=85 I have CF cables for when i want to game, i leave CF disabled unless i need it. Yes i have pretty good air flow, 2 120mm fans a 160mm and a 140mm. I also have a fan blowing on my computer as the case seems to get pretty toasty at the top.
