Title: Nice set-up Post by: marcus_of_augustus on February 26, 2011, 12:05:27 AM This guy got set up for brute force hashing with 4 hd 5970's. He has them all in 1-U rack but not mounted on mobo.
http://blog.zorinaq.com/?e=42 The 5970's are separated off to one side using PCI-e 1x extenders that are modified to re-route power so that none of GPU power does go through mobo (instead of about 30-40%). http://blog.zorinaq.com/?e=44 Saves money running more units off 1 mobo ... Also mentions that the HD 6990 maybe coming out with about 28% more hash power than 5970, anybody confirm this? |
