a friend is selling me a miner s5, I want to buy but I have a question that means those two asic X in the status section, someone help me please if these X will be a problem for the future, thanks
the psu could be a it underpowered
those x's could be corrected by
a) a better psu > I don't know if you have a good psu but many are out there for cheap
b) dropping freq from 350 to 343 > easy free to do
c) a simple software reboot >easy free to do
d) by only a full rebuild of your gear > costly not worth it
so I can only tell you that it may be fixable really easy via b) or c) above.
worst cast they are truly dead and you lose a few gh not that many.
Ask to pay a little less 5 or 10 bucks.
see your error rate at 0.0354% it is a bit high so the clock to 343 may fix everything
