I'm running my 6900XT on windows and the miner is doing quite well except that I am getting a large number of the following messages:
time: 4
Have not received response from poolOther than that, there were times when this wasn't occurring that I was seeing 71 MH/s as the Average (3 hour) hashrate at the 2miners pool -- which is about 12-13% above anything else I've ever seen! (512 intensity; 1642 MHz GPU; 2122 MHz Memory {Actual runtime reported values} @ 145 Watts).
Great work!
