The "ASIC status" on some of my 400M overclocked Antminers show all x's (i.e., xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx) yet the temps are fine (~44-46) and the hashrate is still showing about 200 GH/s, as well as hashrate on my pool staying the same. Is this a warning that I'm slowly burning out the unit?
They can be temporary indicators as well, check with your pool that they are receiving valid shares at the hash rate that your unit is producing.
