        Wow, I really need to undervolt my cards.
        It’s been hitting 35C to 40C in the afternoon.
        My cards are recording temperatures of 84C even with GPU Fan set to 100% and a standing fan hitting them at full blast.

          Sounds like the painful week I just had in Melbourne… I fried a PSU as well :-[ Just gave up in the heat…

            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.
