Are you sure it will be fine? I mean the miner also fluctuates allot from 800Gh/s to 1022Gh/s. Also what do the hardware errors mean, and like can you find out what it is?
one more thing is, when I plug a screen into the Raspberry Pi while its booting and is mining, it gives out random numbers. saying " ip 5 6 7 8 "
Which clearly isn't an ip. Because the one I use is 192.168.0.53
ckolivas is right the HW errors are a very small amount shown, noting to worry about. Are why are you plugging in a screen in during mining? Is it a old one with screen or are you trying to add one to a newer dragon?
