Hi,

I think the Antminer S1 controller has bricked during the flashing process. Well I did not do anything wrong, download from bitmain, upload and verified successfully, wait, but it takes forever to complete while waiting to the luci UI to appear (well, it never appear though...). During that time I noticed the rx/tx LAN port flashing behaviour is no longer normal. orange LED no longer light up and it keep on disconnect/connect (the router link LED is on and off).

tried to follow the failsafe

http://wiki.openwrt.org/doc/howto/generic.failsafe

but the green LED on the board does not show any sign of failsafe mode. after the flashing, the green LED is not flashing rapidly even with the reset button to initiate the failsafe.

Any successful unbrick controller? I need a proper guide. Huh

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

Thanks for the information. Fancy math indeed! I wasn't able to "reverse engineer" the calculation (ie take a desired frequency and find the Hex value that I should use on the mining script) but I was able to calculate valid values for all the 4 digit Hex numbers. I found a lot that were supposed to be valid but they didn't work when using my U2 with BFGMiner. Maybe my math was wrong or maybe the U2 don't take all valid values in the formula. It's more probable my math was wrong, since I got some weird "valied" values, like 306.1429 or something like that. Will keep experimenting and create a list of valid HEX/frequency combinations.

i threw out the paper i was working on, but the biggest factor is to determine your desired frequency and work backwards.

Final Freq (lets say its 300) = 25Mhz (this wont change) x [N/M] (M being 1, 2, or 4 based on the last hex value being a 0,1,or 2 respectively).

That makes calculating 'N' from the formula a bit easier. Once you do the method 2 or 3 times its easier to predict the hex code you will need. (for example, the 200-225 range is generally a x0yz with x being 4 or 5 in most of my work for that frequency range.

and using the U1 or U2 as a testbench is a great way to see if it will run and check if the average hashrate is what you expected.

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

https://www.youtube.com/watch?v=72FU4Z_n0B4

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

this video worked for me thank you

Hi all,
I have 2 S1 ants version 1.6.

My old version 1.5 overclocked without problem.

How do you tell if its v1.5 or v1.6 please?
(Sorry, can't asset with your OC question...)

it's printed on the controller board

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 Grin

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

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.

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 192.168.0.99:55758

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.

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

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'

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. Huh

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
