Still trying to figure out the value of this firmware upgrade
at stock settings I'm getting 18.9 gHz fans @ 2580 and 3390.
so it's less noisy  and generates less profit.
plus I have to pay dev fee 1.5%.
When I undervoltage even less profit and HW errors
I have a watt meter coming in soon I will keep you updated if it's worth it.....
I'm not trying to be negative here but these are my observations so far .
I will post again with energy usage
