What cooling do you have? I found that I get 80h/s with only 4 cores, same as with 8 cores due to overheating. Really need to put some big heatsink on the CPU.
What, 30 min
This is a long time to find a share
I have a little headsink with a fan.
I bought the board here: https://www.pollin.de/p/odroid-xu4-einplatinen-computer-samsung-exynos-5422-2-gb-2x-usb-3-0-810409?utm_source=guenstiger.de&utm_medium=pvgl&%20campaign=pvgl/guenstiger.de?&channelid=psm
and a SD Card from Samsung with 32GB and a power adapter from ebay with 4 Amp . I had no problems with the heat so far and the noise from the fan is minimal
I got 60 h/s with 7 cores tonight. Now I change the settings to 4 cores, I hope it will be better.
