Antminer s1 Mx overclock

[crazyearner]

What is the max you can push these to taking above stock is the max can get out about 200GH without volatage mods and water cooking etc or can they be pushed up a bit more before voltage mods have to be done to get more into it to push to higher speeds. Right now I have mine at 200GH and running with about 2% or less HW errors.

That's probably as far as you'll be able to get it without modding. IIRC the highest someone was able to have their S1 hash at was about 220GH/s, but that would have been a great clocking miner, and not all S1's can clock like that.

my tests in the link.
upgraded and i'm too lazy to push it more than 208gh/s
depends a lot on the machine that u have, the chips on it

Overpowering the miner is the last way to squeeze more coin out of those S1's.

Put on a PSU capable of more than 2x what is required.

The miner needs a 400Watt PSU, give it a minimum 800Watt PSU.

I only use 650W's on my S1's now and all of them are always over 210GH/s compared to 195GH/s with the ones on 550's.

Noticed when I put on a spare 750W non-modular PSU to an S1 and that one miner always had larger share yield numbers than the others.

If you already OC'ed via frequency, overpower is the last logical option.

Hope this helps.
