All my ant's average between 0.005% to 0.016% @ 375MHz, if I overclock to 400Mhz then the error rate can hit > 5% but then at 400Mhz that the total number of accepted shares on the pool is far smaller than expected and it is not financially worth it when electricity, etc is factored in.

Ok, I get 0% with 350 but when I try 375 I get like 7-10% HW.... Dunno what to try... My PSU is 550W.

That is indeed a high HW rate..

I found my upper limit to 210gh/s average @425mhz



That is pretty nice, how are you cooling?

So that is 3.65% hw errors.

What is acceptable HW rate?

Personally i do not believe he runs it at 220Gh as i already tried 0780 with proper cooling. Screens of proof would be nice.

Bitmain have open sourced S1 miner. Schematics are available so volt regulator data sheet and some instructions.
However, somebody with knowledge need to confirm what resistor to change or pencil mode.
The regulator is a 30AMP part and is running well beyond its rated limits.
Yes i know that, i post this regarding to earlier discussion. But high mhz have high hw errors with 1.1 v. So maybe solution is to modify v of the chips with pencil mode.
Need somebody to confirm which R to change and will that work.

so how far can i push this machine without modyfing it? i mean i can take some extra cooler and put near but i dont want to mess with the design itself.
currently i made it to 220ghs. is it possible to push it higher?
Please post a screenshot of 220GH/s.  Undecided

You can find them here at the bottom: https://github.com/AntMiner/AntGen1/raw/master/manual/AntMiner%20FAQ.pdf
But its 25Mhz/step

yes, exactly i know. I want try 5Mhz to 5Mhz step increase.

someone can share code value from 400 to 425 in 5Mhz step?
for older FW 20131212 and new FW 20131226.
Thx

the grandpa of cryptos
option 'freq_value'      '0780'

+ older FW: 20131212

+ a PSU with gold standart.


if this helped dont be scared to tip me!

Ive tried until 450 mhz and it never does perform over the 203gh/s long term that everyone gets.

410 415 420 425 still gives the same results. At 450 hasing rate is 10 - 20% lower.


Please tell us how you got 220gh/s .
