Ok
looked into over clocking can go 20% but the current draw go up as the chips will want more voltage, but under clocking the they need less voltage and run a lot cooler that makes me think the chips could be set up with a solar or wind unit in another way.
It looks like the chip boards in the cases are those the person above warned about, but I have the newer safer chips unused ready to go, so the other may be good for under clocking with another power system. The computer part looks like an android phone so must be quite simple.
I could be up for making some thing interesting if some one is interested who understands mining, having never done mining, part of it is still a puzzle. My assumption would be collecting 24-36 volts and transforming down to 12 or 10 and 5 volts one could run the left over chips slower and run for very little cost. Linked to a battery could be set to shut down and start up when power is available. I have made remote devices in the past, mostly radio type transmitters, but other stuff too.
I will see if i can under stand the circuits when i get time.
Just a thought to throw out there

Hello again
1st question - overclocking yes i believe they can but i have never used them a little research needed
2nd - I was hoping to sell as a lot in person as i have a number of updated chips also and i have not tested other than plugging one in. Or ever mined before, so my under standing on how they work is limited. Hoping for £650 the lot, but would ask £200 for one.
As for the second comment, i have a quantity of updated chips that i assume solve this issue. But would prefer to sell to someone who knows what they are doing. As far as i am aware these machines have never been used.
Hope this helps

Just check the part number, these machines tend to fire up (litteraly) unless you have the latest board version.

Hello
Can these units be underclocked?
How much would hoy ask for 1?
Thanks

hello
i have 5 blackarrow mining machines from the past, they are all the same
the model is :
Black Arrow Prospero X-3 and they are rack mounted with Minion chips
best to look the model up if unfamiliar
the specs say any where between 1200gh/s and 2000gh/s
also these can be over clocked
i have not used these and the previous has not either as far i know
they are a little bit cosmetically damaged though
i pugged one in and it fired up fine although did not try hashing
also have some more chips from the same period (slightly newer)
located in the south of england, would be happy to deliver to some locations in the south
surrey, sussex kent and london then they could be tested properly
please send pm if you need my number or post questions
prefer offer on the lot
