Luc -

Something's up with fixed difficulty - I have my 4 s9's set difficulty (_diff1500). Been running stable with much lower invalid rate and higher sharerate for the past 3 days. About an hour ago I noticed a problem with one of the s9's. The difficulty is now auto vardiff. My settings have not changed. I've reset the miners.

Any changes you've made?

Hashrate(valid/invalid)
15 minutes :
47.97 TH/s
6.19 TH/s
1 hour :
47.90 TH/s
5.15 TH/s
3 hours :
49.51 TH/s
5.50 TH/s
12 hours :
51.84 TH/s
1.86 TH/s

What were you getting with 1500? That seems really low for an S9.
