The dates stamped on the miners are not when they were manufactured, but the model of the boards.
indeed.
i had much less issues with the newer boards that were delivered first.
this time im using a cougar gx1050w, was dubious but its fine and i like its PCI-e cables. nice and chunky.
OC'd them to 375 but these older 2 seem like they are happy to go to 400.
we'll see how things look after 24 hrs
these slightly older ones may need their firmware updated...
i want another 3-4 but not really prepared to pay 1.45 for them any more.
