sorry guys I need to know your miner
I use this
https://www.dropbox.com/sh/zhfbr8xh6zw0gi0/AACRBQNt63MeI18RlRXzgd-Ba/WIN-x11-sgminer-wolf-kernel-b2.zip?dl=0my card 3x 290x oc
gpu 0: 63.oc 1514RPM | 7.032 M
gpu 1: 75.oc 2230RPM | 8.066 M
gpu 2: 75.oc 2230RPM | 8.066 M
total 23.13 Mhash
if you use another miner there is much difference between the gpu0 with gpu 1 and 2,
But the most touching Mhash are 18.23M
I tried everything, uninstall the drivers with DDU
changing position of video cards
without any positive results
MY PSU corsair RM 850.
you have any solution?
If you use correct wolf0 kernels the result above is poor! Even 290 non "x" easily hit 8.5M on x11
