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
