I received my A3 this afternoon and having been having some problems. When I first set it up, everything was working flawlessly. Hashing at 833GHs on Siamining, no HW errors, everything smooth. About 2 hours later I checked again and saw my hashrate dropped in half with a bunch of X's on one of the hashboards. Since then I've only been able to reach 500-600 GHs, and am getting HW errors on different boards whenever I refresh. Anyone else having issues? I would normally try reflashing the firmware but it's not available on Bitmain's support page.
