Im using 275 frequency @ .745v for testing which is broken in the firmware (you cant set it in the dropdown menu it comes up as 2,275MHz) Shocked

The closest you will get in dropdown is 268.75 which is 1085GH/s ...bitmain really needs to update the firmware for these but they do a great job for heating with minimal noise
Ambient room temp is 72F
Depending on which batch of C1 you have, there are different fans on the rads...it will either be 3 fans plugged into 2 headers which are the more powerful fans, or 1 fan into each of 3 headers which I believe are the first fans that were used....the lower powered fans use .1A less than the stronger ones not sure of exact numbers but there is a difference
When Im done testing the Avalon for efficiency I will plug the C1 in to my APC and see how much power it draws at different frequencies...give me a day or 2 time permitting

I was looking for underclock not overclock..

Also my firmware allows me to do 275 freq, Maybe u need to update ur miner
