@PhoenixMiner,

I run PhoenixMiner 2.7c on 6 x GTX1070 Ti (Win 10 Pro build 1709) smoothly, until these last several days.
Every time after I run it for several minutes, one of my cards suddenly lost its memory OC setting and back to is default memory setting.
It happens when the miner restart, right after it crash (after connection error to "d3pool.eu/api/status").
I tried to ping "www.d3pool.eu", but the connection is okay and no packet loss.

Here is what I found in the log file :
