Hi,

yes, tried this. At the moment I'm on 550MHs again but due to freq. it should be 600MHs. I had to do this game several times but after the last "failure" I couldn't recover the miner. It was hashing at 2GHs and started to decrease hashrate over the day. At around 1.4GHs I restarted it and since then it never got over 600MHs again. I have to do very small frequency steps and around 100 Accepts before increasing frequency otherwise bfgminder or the bitmaint cgminer report 0 or something starting with c5xxxxxx after the getfreq command. If this happens the miner is f**** up again and I have to start with a lower freq until it recovers.

Thanks for your reply,
