Title: [solved] CGMiner crashes on second run. Post by: SirGolan on December 23, 2013, 09:25:29 PM First post here.. I'm having an odd issue with cgminer 3.7.2. I've got it set up with what seems to be stable parameters for my 2x Sapphire Dual X 7950's, but if I let it run for several hours and then go to restart it (to switch pools or whatever), it locks up the display drivers bad enough to require a reboot. If I leave it alone, it runs fine for hours.
I'm on Win 7 with a 1100w power supply and Catalyst 13.9. Right now, I've got one card turned way down since I have an airflow problem, but here's the batch file I'm using: Code: setx GPU_MAX_ALLOC_PERCENT 100 Getting about 620kh/s on gpu 0, which I think is pretty good for I=17. Temps are 68-70C. Anyone have any ideas what could cause this?

Post by: SirGolan on December 24, 2013, 10:52:13 PM Well you should use the "services" section somebody might help you anyways try the last Cgminer version, just in case. Will do. That was my first post, so I think I didn't have a choice but to post it here. I saw somewhere else (probably reddit) that it's best to start with lower intensity and manually increase it once cgminer is running, so I'm going to try that when I have time to deal with the reboot. I've only seen one person mention the lower intensity trick, so I'm skeptical that it'll help. As a side note, I realized that I can add/remove/switch pools without exiting cgminer, so I'm just doing that for now. Thanks! Title: Re: CGMiner crashes on second run.

Try -i 13 Title: Re: CGMiner crashes on second run. Post by: SirGolan on December 24, 2013, 11:47:05 PM What AMD driver are you using? I had probs but now I'm on 13.9 Try -i 13 I'm on 13.9 as well. -i 13 gives me about 330kh/s. Starting up with -i 13 may help and then switching to 17. I'd go higher, but this is also my main desktop and 17+ starts to kill performance. It seems like most of the 280x configs use -i 13, 8192 tc, and -g 2, but I think those have all given me worse performance on my 7950s.. I'll give I 13 a try in a little bit though! Thanks!

Post by: SirGolan on December 25, 2013, 12:41:26 AM Starting with lower intensity (11) stopped things from crashing completely-- looks like explorer is dead and there were some display artifacts, but I'm still here typing this message. But also, hash rate on one card went down to 4kh/s. Increasing its intensity to 13 inside cgminer made things more crashy. Going to reboot and try some other settings, though it's hard to know if anything worked until after I run it for many hours.
Thanks again for the suggestions! Worst comes to worst, I can manage stuff from within cgminer and never quit out as long as when I go down to intensity 8, it doesn't interfere with my work (gamedev, so using 3d accel).
