I'm getting way more hardware errors with that, the miner I update was steadily hashing at 525GH/s (+3 hours average) and its now struggling to keep up to 500GH/s (just a few minutes hashing thou).
I'd not recommend upgrading if your miners are running fine. You know how we say, "if ain't broke..."
What they added to the webui is the temps, pretty scary stuff, ASIC slots preaking at 70 Celsius
thanks for sharing Rampion.
edit: are you planning to downgrade the fw was installed before?
I updated only one of my miners, will wait 3 hours to check the average and decide then.
About temperatures:
ASIC slot #1: 57.0 ℃
ASIC slot #2: -
ASIC slot #3: 63.0 ℃
ASIC slot #4: 69.0 ℃
ASIC slot #5: 63.5 ℃
ASIC slot #6: -
What I can tell you is that for now I'm seeing much more hardware errors and a crazy amount of this "core disabled - core enabled" messages, way more than before.
