How do you create the image? I took the files that you posted before but doesn't work for me. I need to connect 4 blades with one control board

That's great, but it's the opposite of what I need. I have 18-pin controllers and a 16-pin board. If I have time today I'll just do the probing and figure it out.

I repeat my earlier post. Maybe this will help.

I share  again one finding .

You can use new S5 Hash PCB  ( 18 pin connector)   with S5 Control PCB  (16 pin connectors) Need only a 16 pin cable.
Picture of my water cooling S5 project    3 x old blade + 1x new 18 pin blade.

I am not certain, but the top diode in the level shifters and an additional buffer chip (U3 on the bottom Stage) were fitted when they went to 18 Pin and I think it's something to do with Test Mode for the chips?

Rich

Since this thread is already here, I might as well use it. Today I resurrected a dead S5 board but it's the early version with 16-pin cable so I had to borrow a controller to test it. All the controllers I have running around use the 18-pin. I have the 18-pin signal pinout already figured out but I haven't done anything with a 16-pin before today. Anyone know offhand what difference there is between the two?

There are a few ways one is use this http://www.ebay.com/itm/181694032917?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT I have one or two i need to test out if they work they may save a few S5 but not stop it  .

but they keep selling on ebay it seems so they may work, i haven't got around to testing the ones i have but plan to soon.

as for S5 cables 16 pin or 18 pin  


J4bberwock ,  said he will have a lot in stock at the end of the week . better then the ones on the S5's now, I believe it, by some stuff i  have bought form him, it's better then bitmains stuff as a replacement.

I've got a two-chip test board that I can wire up to either an S5 controller or to a USB adapter. Since we don't have multi-chip code yet (soon though) it was fairly irrelevant to run it off the USB adapter but irrelevant is not impossible. Shouldn't actually be that difficult to run an S5 board then, I think, provided you had a working cgminer driver.

Mildly curious (only mildly) about how the blades are controlled and whether it would be possible to replace the controller board with a Pi (for example). More effort than it would be worth for me though.

(Sorry, definitely getting off-topic there)

Or do what many of us did.
Cut the blue wire and fuggedaboutit.

I do think it is a cool project to run several hash boards from one control board, but I still put second fans on my S5s and clip the wire.

I have one S5 with a flaky hashboard. I never know what I am going to get when I cold boot, and then software boot. Usually two xx.
Input power is great.
Methinks temps are good.
I need to get off my arse and swap the boards and then check cables if needed. But she is running today. I have a feeling she will not do that for too much longer though. I thought I'd have a reason to go move things around and pull her by now. Maybe next week. 

Hmm. Interesting. I wonder if there is a way to make the chips stop working. I'll have to try some measurements.

And I've resurrected zombie threads a lot older

That cgminer stops actually is the problem. It can happen that the chips continue to do work even if cgminer stops, which since I saw it happen once on a Compac I think it's more a chip thing than cgminer. But cgminer I believe controls the fan speed, so when cgminer drops out so does the fan. What you need is something independent of cgminer to wrangle the fan based on device temperature.

Also I'm not sure how many people are still worried about it four months after the last post in this thread.

Should it not be fairly simple to write a script which will stop cgminer if loss of connection to the internet is encountered?

(I don't know why I'm posting that as a question. It is)

2.0 mm refers to the 'pitch' or the distance between terminals if I understand correctly.

Are you looking for just wire, like to splice your existing? I did that with 22 guage 'hookup wire' from Radio Shack.

I thought, based on your screenshot, that you already had found longer wires or spliced them or something, and that you were using some nicehash firmware. NOTE: I just spliced my connectors and, at first I had the same problem as you, no, or very few extra hashes (mine actually went up to like 1300, oddly), even though the hash boards show up as all o's. Others have said the latest firmware doesn't work. So I flashed the Jan 7 firmware that I happened to have saved off, and it WORKS! Getting 2300 gh now. I tried to post a pic but I'm getting 'invalid image' so I'm not messing with it. But, it works!

So don't give up on it. If you want the Jan 7 firmware I can get it to you. It's still the .tar.gz file that bitmain provided.

exactly!! this has been confirmed by support that its caused because bitmain set the miner to run test hashes for whatever reason. this causes the miner to mine locally and constantly discard the hashes because they cant be submitted anywhere. bitmain said it will be changed but i still havent seen said change made yet and judging by their updates i might not want to upgrade to this change anyway because it breaks support for 4 boards. but really this feature is wasteful and not needed at all! it defeats the purpose of having the miner stop hashing when it hits 80 degrees because in the backround the miner will just continue to hash away. sure it isnt submitting the hashes to a pool but it is still sumitting hashes....just into the trash pile locally so again it doesnt actually stop hashing.





now on a side note who wants cables?? i can make them for people....noy spliced together cables either but 1 solid cable allowing folks to connect 4 boards to each controller....the only thing is you will need to reuse the plug from your current cable. so you will have to pop the old connectors out of the plug which takes all of a few seconds and then you slide the new custom length cable in there. i will start a thread in the for sale section when everything arrives but until then shoot me a pm if you want cables made. i can take pp and btc as payment and inside the us it wont cost more then 2 bucks per shipment since i can pop them into bubble mailers i use to ship stuff on ebay so ya. outside the us will cost whatever that costs. i made my own cables by splicing them before finding the stuff to make them myself and let me tell u splicing them is a huge pain in the ass even with the use of the "helping hands" tool.

but ne way lmk if interested via a pm so i can guage the interest in this and see if its worth offering the service to folks.

You can take the cables from a s3 and modify them to work. Thats what i do.

1- The name of this part is called an "ECB SPI Cable"
2- Bitmain will not likely ship it no matter how much you ask; you'll only get run around... I fought for weeks and got nowhere.
     2b- Reason being, they don't have a department for parts only.
3- They're a manufacturer, parts should be the job of retailers... but if you buy from the builder, you're SOL; no retailer sells parts.
4- I guess you could make them, those things tend to go because of a bad connection or grounding itself at the wrong place.

If it is still under warranty, I would get an RMA in motion.
If not, run the miner as it is, keep your eyes opened for something that could work.
As others mentioned, you can make your own wire.
But if you're like me and time is limited, you're better off to mark it as "sick" and keep it for parts.
It's funny the shit you scavenge in mining... both on and offline.

If it's just one miner out of many, just replace buy a new miner and/or sell for parts.

anyone know where i could find 2.0mm jumper wires? cent seems to find them

No. Miner only stop hashing, however, miner will not continue give out warm.  But now I have a bigger and better pump.
SC-750WATER PUMP  http://shop.syscooling.com/goods.php?id=26

However, too small radiators for 2 x S5 . I  use a total of three sets of Antminer C1 radiator  connected together.

All my C1 have been rebuilt for S5 style air cooling.

Not to sound rude but im confused by ur reply and its probably on my end...u say the cutoff works and it stops sucking up full power when it hits 80 degrees c or higher right?? But u say urs reached 120c+ which is 40 degrees higher then the cutoff. If your refering to cg miner stops hashing then ur right and wrong because yes it drops to 0gh/s BUT the miner is still using 600w at normal 12v power so the issue isnt that it doesnt go to 0 its that its still running in the backround which negates the shut off function that is in place. If they use 600w while hashing and while not hashing something is hashing that isnt visible. Bitmain replied to my email saying im right and that this issue was being worked on by their "engineers" and that they will provide info shortly and thats the last i heard from them. They said it has been programed to run hashes all the time even with no network conectivity it just discards the packets over and over which is y it uses 600w all the time. As a comparison if u look at the sp20's when there is no network connection it stops hashing period. The power drops to less then 50w but bitmain doesnt. So if it hits 80 degrees it should stop all activity with the exception of the controller until a set period of time has passed then it checks again and if the issue is resolved it fires back up but if not it stays shut off until the next check and so on but it doesnt. If one feature is broken the other will not work either so since this whole no network shut off doesnt work it makes the overheating temp shut off not work and just keeps pushing 600w through it until the board fries or catches fire. My damn heat sinks after less then 1 minute were ticking like a warmed up car does when you get out. It shouldnt have hit anything higher then 80degrees not 81 or 82 or anything else.

Make sense??


I should prob add the following:

1. Running stock s5 image not this nicehash image or whatever ur refering to.
2. Not running the latest firmware update from april....i updated when i got the miners and that was to the one with the date of the 7th.
3. Running 2 blades at the time of this issue. I have tried with 4 blades without issues but this actually happened when i separated the 2 miners and went to configure it after placing the controller back on the one that had it removed. It was by chance this happened because again i didnt fully seat the fan cable by mistake which i know was silly to do and im at fault there but that doesnt change ne thing else im saying.
