I installed the 575 firmware version to test it out and it seems to hash less then the turbo firmware. Is there something you changed besides frequency? My miner on turbo mode 550mhz I hashed an avg of 49 to 51. And now my avg. Is 47 on 575mhz. So not sure why now it is getting less with your firmware. Any help will be appreciated. Sucks to now make less
Crypto305, if your system is not handling 575Mhz, you should downgrade back to the factory firmware. You either have a power issue, or you simply did not get a machine that can handle overclocks well. I would first power down, swap power connections between boards, and try again. Keep track of which power board you move the connections from the middle board to. Try 575 again and see if the problem stays with the board, or moves to a different board.
If it stays with the board, you may simply be limited to 500 and 550. :/
Thank you,
