Right, my bad.
How come is 60Gh though? From all I know is still advertised as 50 GH/s Bitcoin Miner.
Is an upgrade possible, like the one for the 5 GH units?
Or 60GH was back then, at the time when you ordered?
It was originally advertised as a 60 Gh unit when I ordered. All the units I ordered were advertised as 60Gh. I didn't have to upgrade.
