so stock it is only working at 1.4 TH/S not 1.7 TH/S as they listed ?
you have a choice of watt settings. 70 to 288
288 is max and will do more then 1700 maybe 1750
problem with this 288 x 4 = or 1152 watts
very few pcie wires run well at that setting
evga 1300 and evga 1600 can do 250 all day all night for months. I have done it with them.
I have no other psu that will do that with stock wires.
So if you want max setting of 288 to get your 1750 you are really pushing the machine
Like I said it is their marketing decision.
I would say this is a 1600gh machine and with a carefull overclock it does 1725.
Since I set my machine at 180 watts x 4 = 720 draw or 750 at kwatt meter vs 288 x 4 = 1152 draw or 1300 at kwatt meter.
I don't care a single bit about the difficulty to reach max gh.I found this to be very true with gpus back in the day:
you may get .5gh with a hd7970 and use 170 watts
crank it to the max you get .66gh and use 300 watts.
Hard on the gear hard on your ears . ( < That reads like porn not meant to)
So I underclock and I am happy. Those looking to squeeze everything out of this machine will need really good pcie wires really good psu's and will be maxed under 1800gh for sure.
