BITMAIN Antminer S1 support and OverClocking thread

[daddyfatsax]

My PCI-E cable is Hot. Any one experiencing it?
I config is as follows:
Two Ant S1(Clocked to 393.75MHz) connected to One Corsair AX1200 PSU 1200W.
Total four original 600W PCI-E cables used all 4 are hot. 

My cables get warm, but not HOT. As long as you are not using any cheap extenders, you should be ok.

I use the original PCI-E cables from corsair(600W) and no extenders. I feels like its more than warm.

So you are using the cables from a 600W Corsair on a 1200W Corsair? I have an AX 1200 and all of the PCI-E cables say "AX1200 only" on them. I don't think it would cause an issue, but it may.

The PCI-E cables are labelled 600W each.

I'm running 4 Ants split between a corsair 750w and my 1200w. I can stand and hold cables with my fingers and they are only slightly warm. If yours are too hot to hold for more than a few seconds then I would try some different cables. Just my opinion.

Its hot but can hold as long as i want with bare hand.

hot cables can be an issue. if its too hot to hold thats a problem. if its hot enough that the plastic/rubber coating on the wire feels like it is getting soft then you might be creating a risk that it could melt and cause fires/shorts

an easy solution to warm cables is to put a fan nearby so a little bit of airflow goes across them and carries away the excess heat. just a little bit of airflow can drop the wire temperatures by 15 degrees or more

Thanks for answering my questions about overclocking and power guys but i had one more question i was hoping you guys could answer, i just got my antminer s1 in the mail and set up yesterday and last night i overclocked it to 375ish it ran okay for a little while then a bit later i noticed that it was not running at top speed. It was running at 125 GH in the over view tab i saw that about 3/4 of my chips were not working, so i rebooted the antminer several times and it changed nothing then i shut down the psu it was on for about 5 minutes and the chips came back online, ive googled every thing i can think of but cant seem to find an explination, should i be worried about overclocking or is this normal?

these are the settings i used and there were minimal hardware errors.

option 'freq_value'     '5f05'  #350M
option 'chip_freq'      '393.75'
option 'timeout'        '36'

Is there a step by step guide on overclocking the s1 with putty or similar ssh? My stock s1 only hashes at 160

This guide enabled me very easily to overclock my Ants 2 of which run at around 208. However a third one I had was always hashing 20 or so less than the others even overclocked, it was a bit of a weakling!! Maybe yours might be too http://www.rubicite.com/Tutorials/AntMinerS1Tutorial.aspx

I don't OC to 400 though i set the frequency to 375 less power and less hardware errors.

Wondering if anyone can help, I did look at the 37 pages of overclocking info before posting, saw nothing related, if this belongs in a different thread please let me know.

Solo mining with some s1's everything connects up but my getwork rates go through the roof and stuff just isn't right and this is why:

Code:

accepted connection 192.168.0.99:55772
disconnecting node 192.168.0.99:55772

This is from my .qt debug log and I have no idea how to fix it. It will just go on and on like that trying the next higher port? Any advice would be greatly appreciated.

How much is your ghs and HWE%

Hi all,
I have 2 S1 ants version 1.6.
Overclocking don't working on it.
I try
option 'freq_value' '4E81'
option 'chip_freq' '375'
option 'timeout' '38'


option 'freq_value' '5f05'
option 'chip_freq' '393.75'
option 'timeout' '36'

and 400MHz too.
Ants go to reboot.
Anybody have same trouble?

Ants received today from bitman.

My old version 1.5 overclocked without problem.

Does any one knows the logic behind the Hex values for the frequencies in the S1 miners? I understand Hex #s and little-endian and big-endian notation, but it still does not make sense to me. E.g. the jump from 200 to 250 to 300 adds x0200 to the Hex value, so they go from x0781 to x0981 to x0b81. Logic indicates that the jump to 350 should require a value of x0d81 instead of x4e81.

Thanks

there is documentation in the github manuals for the U1 usb device. It relies on a weird mathematical method of several combined binary strings from the hex code.  Once sorted out its *relatively* straight forward to calculat eany frequency you want, to about 1.75MHz precision

Thank you (obvious really.....Apologies for such a bone question)
This explains a few things
My 1.6 runs cooler as the FAN spins quicker at 2200 so is louder than my 2 x 1.5 that run 3c hotter where the fans never go above 1800 so they are noticeably quieter.
All 3 have pull fans on the "open end" in preparation for the English summer
