mining issue

hi.

i have 4 gtx 1070s and 4 riser x16s but cannot get my monitor to work plugged into one gpu. previously i had 2 on the motherbaord and 1 risers, worked o.k. i have upgraded mb to 1.7 as this allows 6 gpus but still not working. i tried moving the risers pin around but nothing works.
any ideas?

You probably have the onboard graphics set as primary (Intel® HD Graphics 510) so plug your monitor into the mobo.

thanks tried that with gpus attached doesn't work if i remove gpus can use onboard gpu.

just switched around the plug and it works on 1 gpu so that is good. now 3 gpus seen on pc but 1 not so think dodgy riser?

Could be. Try to switch risers.
I see the MB has 4 pcie1x and 3 pcie16x. How did you connect your GPUS?
Maybe you need to apply short wire the one in pcie1x.

cheers fixed it i had put one of the connectors in incorrectly to the pcie doh all sorted.

just one thing 1 gpu always runs around 10% less hash than the others any ideas?
