Dear D9 customer,
As the difficulty of coin digging grows, to better serve the customers and bring more profits, Innosilicon optimizes the firmware of the D9 miner. After upgrading the firmware, the D9 calculating force can reach
2.4TH/s.
The specific updates are as follows:

is this normal?
I also updated the firmware, here are the comparisons for me:
Old Firmware: 2.05 Th/S pool hash rate, (2.36 from GUI) @ 830W, Average 75C with fan speed at 75%
New Firmware: 2.35 Th/S pool hash rate, (2.4 from GUI) @ 950W, Average 71C with fan speed at 55%
Obviously, I've only been running with the new firmware for a couple hours, but so far, it seems better. I have not done the auto-calibration.
Edit: Added hash rate reported sources.
Are you seeing crazy hashrates directly from the miners like I am? They are wildly swinging up and down now.
