This is problem I have when ppl buy all the gpus and then want to sell them but aren’t honest . Just say you mined and let’s move on with selling the cards
Not overclock |OR| Not used for mining :
by logic
true || false => True , they were not overclocked but they were used in mining , case closed . you lose .
hum, if they are a 1 month old i dont believe he used them to mine. Maybe he bought them to mine, but didnt know how to. Even if he did, 1month is nothing...
