BITMAIN Antminer S1 support and OverClocking thread

[Gamer67]

There is a special formula for that not just the raw HW number.

^this. IIRC its     error % = HW / (HW+diffR+DiffA) x 100%

most of my units run between 0.15-1.05% error rates. I would say that up to 2% is fine, but more then that means you should tune it down slightly and it will be beneficial.

(ie: 2% of 204GH at 400MHz is 4.08GH lost to errors. if that can be reduced to 0.5% errors by tuning down to 393 (~200GH) or 387.5 (197GH) then you will have almost the same hashrate but a little less fan noise and electricity draw to achieve it

Thanks for the info:

I have 2 clocked at 393 and the other 1 at 387.  My HWI% is ranging from 1.32%, 1.65%, and 1.51%.  The power supply should be fine, I have a HX750.  So i'm going to add more fans to it, and see if I can get that lower.

On the same note, has anyone found a way to increase the speed of the fan without cutting the blue wire? 

Thanks again.

You use a small flat tipped screw driver and push the pin out for the blue wire on the connector tab.

Or you can pull the connector out at an angle so just the top pins touch and it'll do the same...

As far as hardware errors are concerned, adding more fans helps a lot more than turning the stock fan to full power... imo the problem is the far end of the board doesn't get enough cool air. I find standing 2 120cm fans on each side facing on to the chips makes a big difference and slows the stock fan down to a 'liveable' noise level

I just got a pair of s-1's today.  is this thread for s-1's and s-2's or are there 2 threads.

The S2 doesn't exist - there's an S1 single and an S1 double blade. Both apply here.

I tried to get my new S1 to 393.75 & 387.50 but both values I tries failed - just beeping.

What are the correct/working values for the clocks between 375 & 400 settings?

When you reboot from SSH command line after editing the asic-freq file, it will not always connect to the internet again... I often get a beeping... just switch the ant off and on again and it will boot up with the new settings.

I don't think this is it, since it booted fine @ 400 (though with a bit too many HW for my taste). Right now it's running at 375 with 0 in the HW column (for days:))

The beeping is a result of no internet connection... that's all I can say... I've not known it to beep for any other reason.

Ok, it might be a coincidence that it won't accept the new clocks.

Can anyone confirm this should work for 387.5?

Code:

        option 'freq_value'    '387.50'
        option 'chip_freq'     '5e85'
        option 'timeout'       '38'

I'm just an idiot Look at the above - I got freq_value and chip_freq turned around I tried 4f01 also and it seems to work.

One of my antminers is overclocked to 400 Mhz and it is hashing stable around 200 Gh/s / 41-43C°.

Btcguild is showing average of 200 Gh/s as well. The only thing bothering me is HW errors. How can I check what % HW do I have.

Does this equal 0,3% ?

It has been said many times in these threads, search is a wonderful thing 

HW / (HW + DiffA + DiffR + DiffS) = %

[Moebius327]

I am around 0,03 HW then?

Edit: It was a stupid question indeed. Thanks for the help!

0.03% is a good error rate for an ASIC, other vendors would love to get it that low and at that wattage.

You temps are low, your fans at half speed, your chips are good, sit back and relax!

PS: It wasn't a stupid question, just a lazy one

don't forget to multiply by 100 to get your percent


HW / (HW + DiffA + DiffR + DiffS) x 100 = %

Glad you found the problem, how's it doing?

Been having trouble with an older machine that won't clock over 387.5mhz without too many hardware errors and finally found that the boards have changed capacitors. The older board has 1200uF caps and the newer more stable one has 1500uF caps running @ 400mhz with 0,67% errors... I guess that's my problem because I've eliminated everything else.

227098 / (227098 + 128*59030 +128*236+128*29) = around 2,9%

Yep, that's around 0.22% error rate... exceptional for an overclocked unit if you ask me... but you have quite a high reject rate, I get about a quarter of that... might be your pool or internet conn., not sure.
