Changed the diff to 2050 and everything looks good for now and this also shows best share now. The only change i noticed is utitlity became 12+ whereas it used to be only 3+ in past. What does this mean actually?

Changed the frequency to default after few minutes on the miner which i was testing. (I was not messing with the miner which was problematic). I was just testing it to know the change in Ghs if any.
By the way i dint know over clocking voids warranty as it states -+10% overclocking,underclock in your website on s4. what i did is like 5% increase in frequency i guess.


That is the wrong number.... but if that works for you, keep it that value!!!

Over Clocking will void your warranty on the unit, please be careful  Cry


Thanks for the response, but for some reason our hosting guy suggested to put /8192+8192 in miner settings. Will change it to +2050 now.
The stats i posted above are from control panel.

About connecting to BTCGUILD, i will soon do it and let you know the results.

About frequency, changing it to 212.5mhz with default 725volt is showing 2100ghs avg but hw errors seem to be more but the % is negligible though. I doubt if the miners power consumption increases by changing the frequency but not the volts, any idea on this?


Please try setting the pool side DIFF to 2048 or +2050

You can try connecting to BTCGUILD.COM and see if x goes away or hashrate goes up to where it should.

The hashrate you see on the control panel and the poolside may varies due to many different factors.  Our guarantee is the machine side hashing rate


Thank you!


I am running 3 s4's since 3 weeks and have few doubts to be clarified by any experienced users. Our machines are hosted somewhere else.

In the beginning hashrate was very unstable and after upgrading to latest firmware, they became lil stable. I use p2pool.

-what does hard reset mean? In-detail please?

-1 of our miner has lower hash rates with 1 or 2 'x' asics failing always.After running it for sometime x starts appearing. Contacted bitmain and they said to test each blade and we did all troubleshooting stuff and they worked fine when connected to separate blades. Again after connecting all, 1 'x' appeared and hashrate is slow after 10hours compared to others.
For example on p2pool with default 200mhz,725v on p2pool with pseudo,actual difficulty set to /8192+8192, hash rates are as folllows after running them for 6days :
miner 1 : 1970gh
miner 2 : 1965gh
miner 3 : 1850gh ( which has asics failing issue)

All above stats are from antminer panel and p2pool graphs shows a different story. All 3miners work with same worker.
deadhashrate overall for 3 miners on pool is 270gh. shall i set difficulty to 4096 for a lower dead hash rate or is it something to do with pool?

- I am planning to overclock the frequency to 212.5mhz on 725voltage. Will that work or any consequences? I have seen people doing 225mhz with 725volt.

comments are appreciated. Thanks Smiley
