Just upgraded to the new firmware. Don't see any differences, still a very high discard rate...
That's about 6% discard rate.... It looks like you are the only one reporting this issue... check if everything is connected properly... What is your reported hash rate at your pool?
Well for me I determine that the discard was a problem by looking at the hashrate from the pools themselves......
S2 is running 45C not bad really.......
