Has anyone had success contacting sales re: RMA's ? Have been waiting on a response for an RMA on 3 bad h-cards

RMA issues aside, these rigs are beasts once they are configured and placed in an environment with proper cooling ! The one full rig I have up and running has settled around 535 GHs !
are you running the 3.0 m/boards? what image file are you using? how are you powering them. is it with just the 2 pci-e plugs? do you have pics?
