my current hardware set up is win10, 16gb, with i7(forget whatverson) and R9 390 AMD vid card
it hashs at around 2-3 Gh/s what it tells me(other miners run at 1.25gh to 780 Mhs). runs at between 66 to 71c temp wise which is fine. so ya not sure
also i put it on dynamic settings which put it at around 9 but i was running at 12 no problems
also i ran it for about 5 hours last night before my power went out(transformer went down)
