Did you buy this secondhand? The Jupiter has a dead die and it looks like the previous owner was overvolting it to try to wake the die. If the die comes back to life, then you start reducing the voltage until it's running stable. The method is approved by KNC.
yes I bought this secondhand! but can the die come back to life? and what is a die exactly?
But I dont think the 'dead die' is affecting something? Because Im still getting 550 Gh/s and that is normal for a jupiter right?
