Title: Issues When Running Multiple Rockminer R4's At Once
Post by: coinwwweb on October 19, 2014, 05:52:53 PM
Hi there,

This is my first post so I am new here, glad to be apart of a great community. Thank you so much for clicking on this post as I really appeciate any help I can get regarding our expensive mining project.

Our problem is that we are having issues with running multiple Rockminer R4's, what's happening is the speed of the hashing boards are getting cut in half and discreased to 50 GHs each rather then their normal hashing speeds of 130 GHs for each board. I am trying to prevent that from happening. Does anyone know how to prevent this?

Our Setup:
Rockminer R4 (x 6)
1300w EVGA Power Supply (x 4)
10 Port Aluminum USB 3.0 Hub

When we run 1 or 2 machines at a time we don't have any problems and our hashing speeds are great! But when we connect them all to the computer at once, that's when everything becomes slow.

Thank you so much for any help at all!
