Try one volt 1000 mv and 257 clock
I will give it a try, thx

.
Friend of mine just started his HEX8A1 board successfull with Odroid

This settings are not working after ~10min, but I guess it depends on my current PSU.
I was wondering about putting a slower fan on the top of the miner and two 120mm on the sides to get an air stream.
What do you guys think about this? I guess it would be much more silent than my curretn 80db

Where the heatsinks aligned like this = or this +?
If they were like this = I was going to build a wind tunnel and put a 120mm fan at one end and blow air over both heatsinks.
But last I saw Marto changed the heatsink design to +. For that configuration I was going to put 2x 43cfm 92mm fans on top with cable ties.
