Also i noticed that newest image is causing on some rigs 4MH/s
So if someone have this problem i suggest using older image while we will investigate whats wrong.
We are investigating, the overclocking did not worked on this newest image so i suggest using older one.
We are looking why is this happening right now.
We also have another small bug that rigs saying at the boot that they cannot connect to simplemining.net
It is false positive but we will fix that in about 1 hour.
EDIT: false positive message about connection problem solved
And new image will be released soon with even newer drivers than before , we found problem
