Title: [Help] Antminer S1 extremely low hash
Post by: cignus76 on February 24, 2016, 04:22:56 AM
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 ;)
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.

It was! I had already came to the conclusion but thank you!

set the freq to 200  your error rate will drop to normal and your hash rate will go up.

don't erase the pencil mod
