I'm also having the same problem with PPC mining from Bitparking's pool. I had no problem with mining BTC from Slush's pool

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.

So there's been no fix for this?

Sorry to thread jack, but what kind of hardware are you using? Are you seeing any profit on that hash rate?

My pool is bitcoinpool, and I'm getting the same thing. 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.

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 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

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.

I have been watching the logs and the drop occurs on a new block. I see this in the log:

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?
