There are a couple of things that seem to slow my speed down from +-300 Mhash/s to only 300 Khash/s.
The decrease is usually when i get the messages:
"long poll: new block...."
and
ADL_Adapter_ID_Get failed, cutoff temperature disabled for 0:0:Pitcairn
This hashrate drop is permanent or for some specific time interval ? When does it rise again ?
It is permanent as in, it will stay that low until i restart again. I don't think there is a specific interfal, once it had been running for an hour or so until it slowed down again.
I check the concole every time to see what happend and it says 95% of the time:
"long poll: new block" with a code after that.
It has also said "long poll IO error"
and it says IO errors - 1, tolerance 2 sometime when i restart it.
the other message that seems to slow it down is:
ADL_Adapter_ID_Get failed, cutoff temperature disabled for 0:0:Pitcairn
which has only happened a couple of times.
the hashing speed does not rise agains until i manually stop and restart the mining.
