I have 5 defective 5970 for sale. Everything has been sold out.A machine POSTs just fine with them. They are detected by the OS. cgminer starts mining, but they hang right away or within minutes or hours. Often, the whole machine must be rebooted to continue to use the card.
I am asking 4 BTC each, shipped anywhere in the US.
I also have
fully working cards for sale.
