BITMAIN Antminer S1 support and OverClocking thread

[rtr989]

Here is my experience with overclocking:

in asic-freq i use this:
        option 'freq_value'    '6002'  #406M
        option 'chip_freq'     '406.25'
        option 'timeout'       '35'

added second fan from russian military device, it sounds loud but gives high air flow.

At full speed (yellow & blue wires detached) how much is the ant s1 fan's energy consumption?

the second fan is ac-power from wall, it about 100w.

Ok. But I was asking about the original fan came with Ant S1.

are you over volting this ant? how do you find the heat from the vregs? are you running additional heatsinks?

I have an s1 running 400mhz with 0.1% error rate, 40C and fan at 1080. was toying with the idea of overclocking more but don't want to blow it since it hasn't roi'd yet and is brand new.

At 387, 387.75, 393.75 I'm getting .9% error in one of my ant. The PSU I used is Corsair 1200x Gold Plus for this single Ant. So Power is not the one.
My PSU cables heats more at 387 than at 397.3 that means more power consumption at 387 than 397.3
What you think ?

Do you have your DNS stuff set correctly? Had this problem when moving my S1's from my home to my office. Home was 192.168.2.1 and work is .254, or you can use google 8.8.8.8.

Yes, I have lots of them and it was working until earlier today, so I think something has gone wrong

If a reflash doesn't cure it, it might be a broken controller.
Can you configure another interface and bring it up? ie: wifi/lan?

Did you take the cover off and reseat all 11 boards 
The AntMiner S2 boards are floppy loose with nothing holding them in place.

[Aurum]

Do NOT buy the so-called AntMiner S2 Kit. It's just a bunch of spare parts. There's no case or any way to secure the motherboard or cards. It comes with 2 fans instead of 5. If you bump into sitting on a table top you'll knock the controller board loose and erase your setting back to defaults.

I'm getting 4% HW errors  using the 387.5 freq settings and only getting 189.7 Gh/s.  I tried both 400 settings (0780/35 and 4f81/36) and I was getting 15% HW errors.  My temperatures are always below 50.   

Is 4% HW error acceptable or is overclocking not really viable for my unit?

4% is high. Anything over 1% and my impression is you are just wasting energy.
My S1 gives a .44% error at 387.5 which is higher than I would like but appears to be acceptable to the community.
Mine are below 50 as well with ambient room temps.

The formula for HW % is HW/(diffA+diffR+HW)*100  correct?  

I assume it looks more like HW/((diffA+diffR+HW)*100)  given that multiplication comes before division.

never wrote it down I just use a website. http://www.coincadence.com/antminer-s1-hardware-error/
Formula: Error % = HW / ( HW + DiffA + DiffR) * 100

Just use the Free Antminer Monitor MAntMonitor1.5.

Thanks. That's a great tool.  This is rather disheartening however.  Any attempt at overclocking results in at least 14% HW errors.

Which is your PSU?

I have one S1 stuck @ 362. I cannot figure it out. I have even copied the config over from another Ant. I have chmod it 644, but it's like it's not reading the file. It is stuck at my last overclock of 362 no matter what I do to asic-freq..lol

Anyone seen this before? Just thought I would check before I reset it. Power off and on is same thing. The asic-freq file is not doing anything.

Try a firmware update to the latest even if you are in the latest. The try again and report. DO you have an energy meter to check the power consumption?

[FlensGold]

I have a problem with my Antminer S2 (Batch 4) hoping someone has an idea.
After powering it I was able to access it and enter network & mining configuration.
The miner started to work, after some minutes it beeped and turned off.
Although I unplugged all power cables, plugged them in again it does not turn on again.

Does anyone have an idea what can be wrong? I assume it is the PSU since after switching it on it stay absolutely nothing happens.
I would appreciate any suggestions.
Regards

Ok guys I really need some help. Like a real Dumb A** I bought the S2 Kits.  I have three of them and now all three are down.  Originally only one wouldn't boot, but now all three are in the same boat. 
When I power them on i get the blue LCD screen, but nothing else.
On one of them I get 3 blue LED's but the unit won't boot
The other two show no lights at all on the board where the ethernet plugs in.  I have pulled the SD cards and put a new bios on them rebooted, re-seated the boards, tried new power supplies.... NOTHING WORKS!  HELP!!
