now i get with Claymore 10.1 only 24,5 MHS - with the lattest driver and with the driver von 23.8 -> what driver do you use for BIOS modded AMD GPUS (Driversetting) to get again the 27,5 MHS?
Have you enabled Compute Workload?
AMD Radeon Settings>Gaming>Global Settings>GPU Workload - Compute.
It's trying to go to us1.ethermine.org and can't get there.
Try to ping and tracert all Ethermine servers, maybe your firewall or your network gateway does not allow it, if you are connected to a dorm/neighborhood LAN network.
I uninstalled then installed the driver and here is the thing it would run smoothly both at default and at oc settings. But the problem is when I shut it down or there is a power outage because when I turn it on again, the miner would crash after one hour and I had to do the same thing over again.
The GPU stays installed
directly on the MB, you shut down the rig, power it up and miner still crashes after 1 hour of load?
