Thank you the reason Im asking is that i bought a used miner and wanted to see if I got scammed. Thank you for all the help. It looks ok all the chips are working
If it were me I would try loading the latest firmware from Bitmain's website. What speed is the miner getting poolside and via the web interface?
^id advise against it. the original firmware works fine, and if you have any issues in the upgrade theres virtually zero tech support on the gen1 gear.
he wasnt scammed - sounds like the unit is working fine and as long as its >170GH then theres nothing to really worry about. set it and forget it works best
