I recently obtained an Antminer S1 from a friend who decided to retire his hobby of bitcoin mining.
I have been following bitcoin since its creation and have been mining on and off for a few years with altcoins, etc. just never had a stand-alone ASIC, so no preaching please Wink

This miner ran fine for him, he returned everything to stock settings and shipped me off with it. I booted it up at home and reconfigured it for my network but I'm getting a real shit hash-rate, and I don't mean a little sub-par, I'm talking 30 Gh/s on a single blade (test purposes)

I've tried multiple power supplies, upgraded the firmware, updated cgminer to version 4.2 and I'm all out of ideas.

Thanks.

It's probably pencil modded. Take a pencil and find the resistors with the pencil mod on and erase it.You should be doing well after that. If not, you probably have a fried board. You can find boards for 15$ and with free shipping on aliexpress for s1s. I've ordered a few from them, and it worked pretty good. It's probably just a pencil mod, though.
