After changing on stratum protocol, my speed drop down in last 24 hours from 82 Mhash to 62 (prize also 0.46 to 0.37).
On other pools all its OK (speed is 82). I go there for now.
Btcguild must solve it.
I connect machine on stratum+tcp://stratum.btcguild.com:3333, and all its OK until yesterday. Today I watch stats and see that speed drop down, and prize so. And this is all. I don't know what is problem, only I write facts. In cgminer stats my speed is over 82 Mhash, and on other pools speed is OK, and prize so.
You can try dropping your worker difficulty to '1' and restarting your miner. You're running extremely slow hardware, and with a default difficulty of 2 on BTC Guild, you will see a lot of variance when running that slowly. However, you could easily end up on the other end with your speed showing up 15-20 MH/s higher.
I don't know what you mean with "You're running extremely slow hardware", my minimum difficulty set on 64.
I reset machine, and nothing help. Now is only some card connect on my account with min diff 1.
