      Undervolted my cards to 1.081 but hashrates at 730khash/sec :'(
      Good temperatures though. 73C, looks promising.

      EDIT: Made a few changes. Now mining at steady 755khash/sec at 1075MHz core clock and 1500MHz memory clock. Same 1.081v

          Anyone know of a windows program to regulate the voltage?
          Starting to think my sapphire 280x toxic are voltage locked:(

          My asus matrix cards had no issue with the asus gpu tweak utility (windows).
          But was limited how low i could set em.

              Mining on MSI R9 280X GAMING cards.
              Hovers around 730khash/sec when I’m actively browsing the net while mining.
