Title: 280-300 Mhash/s randomly dropping to 200-300 khash/s using GUIMiner Post by: zoober on February 20, 2013, 12:46:21 AM Hi all,
I am new to bitcoin mining and when I start mining it goes at 280-300 Mhash/s and then seemingly randomly drops down to 200-300 khash/s. It will stay there until I click stop mining and then start mining again. Immediately after clicking Start mining again it resumes back at 280-300 Mhash/s. Is there a setting somewhere I need to modify somewhere? Title: Re: 280-300 Mhash/s randomly dropping to 200-300 khash/s using GUIMiner Post by: zoober on February 20, 2013, 03:30:31 AM I have been watching the logs and the drop occurs on a new block. I see this in the log:
013-02-19 22:27:12: Listener for "Default": pit.deepbit.net:8332 19/02/2013 22:27:12, long poll: new block 00000374xxxxxxx Title: Re: 280-300 Mhash/s randomly dropping to 200-300 khash/s using GUIMiner Post by: k22k on February 20, 2013, 07:39:12 PM I have the same problem. If I stop and start the miner it goes back to normal. It only happens with deepbit from what I can see. I have the latest guiminer too.
If anyone knows how to fix it I would appreciate it. Title: Re: 280-300 Mhash/s randomly dropping to 200-300 khash/s using GUIMiner Post by: taltamir on February 20, 2013, 07:41:32 PM I think I am getting the same issue. My card can produce 300MH/s but is very loud doing so.
With careful configuration of -f or -s I can lower it. If I leave it on (a stable) 50MH/s before going to sleep I wake up in the morning it has somehow dropped down to 2MH/s However, I am getting it with BTC Guild Title: Re: 280-300 Mhash/s randomly dropping to 200-300 khash/s using GUIMiner Post by: zoober on February 20, 2013, 10:21:40 PM Yeah I noticed it appears to only be a problem with deepbit as well when the long poll shows up in the console. I added a post in the deepbit thread for newbies but no response yet.

I have tried using only 1 gpu, both gpus, same thing happens either way. I'm at around 60mhash/s for about 5-10 min, then it drops to 3xxkhash/s and won't go back up. I'm thinking it's a bug in guiminer. I'm thinking of trying cgminer.

Title: Re: 280-300 Mhash/s randomly dropping to 200-300 khash/s using GUIMiner Post by: (^_^) on March 08, 2013, 05:43:48 PM So there's been no fix for this?

No point leaving my pc on all night Title: Re: 280-300 Mhash/s randomly dropping to 200-300 khash/s using GUIMiner Post by: dogie on March 27, 2013, 03:06:04 AM Without hoping to sound like an idiot, have you checked for any thermal throttling?
One of my cards is almost maxed on idle cooling due to a misbalanced fan blade.

I had no problem with mining BTC from Slush's pool
