Hi all,
I started playing around with AMD cards as it's getting harder here in the EU to find decent amounts of nVidia cards. So after installing Ubuntu 16.04 and the latest AMD drivers (17.50) I got ~20 MH with Ether.
m 13:14:26|ethminer Speed 20.79 Mh/s gpu/0 20.79 [A0+0:R0+0:F0]
Just for testing I switched to EthOS which yields ~25 MH out of the box. With decent overclocking I can easily push that card to 30 - 31 MH.
In my Ubuntu setup I did install the ROCm components and edited Grub to force Large Page Support (amdgpu.vm_fragment_size=9). And that works:
root@ubuntu:~/bin# cat /sys/module/amdgpu/parameters/vm_fragment_size
9
Does anyone know what drivers/settings EthOS uses to achieve that hashrate or what should be done on Ubuntu as an initial setup for mining Ether with decent hashrates? Thanks in advance.
