old question below.

okay
controller is below

https://i.imgur.com/KFOM0GX.jpg



nine 18 pin jacks means 9 blades are possible ?

so we need some longer 18 pin cables and we could make a copy of the s-5+

also if you have 2 s-7's you can pull 1 controller off line and run 6 blades on one controller giving a spare  backup controller.

So we need a source for cables that are a bit longer.

So does anyone have a source for these cables?

Assuming they are willing to sell without making you send in a replacement it is likely you could duplicate the S5+ controller.  It seems it could be flashed via serial if needed and most likely be turned into just like S5+ controller.

Guess we will see if they make S7 controller have a different firmware not compatible with S5 blades.  I think this is likely, but I have been wrong before.  If you can combine it we could see some S7's with old S5 blades on up to 6 blades.

Could be some interesting times.

I'm not sure that it will be S7 controller.
This is only one of the possibilities, and can change already with patch2 S7, or even earlier.

But I am pretty sure that,  as S5+ , as well as S7,  be able to work with S5 controller.

And these are easy to obtain, if you have two S5.

The picture of the controller board for the S7 says on the silk screen S5+ so it "seems" that they are identical. Also it has been reported that S5 & S5+ controllers and firmware seem to be completely interchangeable. As to cables someone must know the part number of the plugs?

Rich

I'm pretty sure those connectors are made by JST.I can't find exact match to them anyway.If pitch is normal 2mm then PHD-series seems to be close enough to fit.Maybe little modified.Those PHD connectors are easy to find,digikey sells them.

good I will look at digikey

http://www.digikey.com/product-detail/en/PHDR-18VS/455-1905-ND/947498

And JST series selector.Select "wire to board crimp style connectors".
http://www.jst.com/home2.html

and maybe even keep using your S5 a long with it from what tupsu said he did  https://bitcointalk.org/index.php?topic=858962.0 :) . some one on Ebay was selling those cables i never gave it much thought then
and didn't bookmark it or save it in any way wish i had now because i can't find it and need some cables made .


ty pinhead666  that helped a lot and philipma1957 found it on ebay http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1311.R1.TR12.TRC2.A0.H0.Xjst.TRS0&_nkw=jst+connector&_sacat=0

Yeah,I've ordered those too.A lot.But you must know that single row and double row connectors have different crimps.

Awesome!

Anyone got an idea for a case for housing 6x S7 blades? Could you cool these chips with the original heatsinks with less static pressure (noise) from fans?

6 "silent" blades = 2420 W = 67% load of a 16A fuse @ 230V, would be nice for the home-miner! At least in Europe (afaik).

you would be set.

I have been thinking on that myself. The main thing is the cables. It is a pain to get them.
Just like the S5 where it would accept 3 and also 4 with a different firmware. The main stumbling block was the cables.
Having to custom make them is tedious.
I do have a couple cases I am going to try this on though for multiples in one chassis.

I have 50 of the 18 pins cables custom made in stock, and also some 16 pins ones for early S5s.
12" long, they were like 1$ each. if I remember correctly.

There are/were for the S5 watercooled case, and some other projects, but it seems that they can serve other purposes.

Edit on availability and pictures

Innteristing stuff guys,

Do you think it would be a problem to place it on it's side? Then you don't need longer cables.
I only ordered one S7 at the moment. (not that rich)  ;) But when i do order my second will try that.
Then a nice box around it, a little overclock and you have a nice 10 TH home miner.  ;D ;D

I'm interested to get some of these cables

Even in the us is is not that bad.  I owe Phil for his help on it.  But I love my 240 after getting it in.    I for one doubt I run another 120 line for mining after.

Having 30 amps and a pdu separating it is just amazing for the new miners.  It will not work for all but I really think at least bitmain is going to keep releasing bigger miners compared to the past.

PM sent .

all my 18 pins cables are sold.  :'(
some 16 pins ones left.

I didn't expect so much interest.
I'll take 200 more with my next order from this supplier, approximately 3 weeks delay.

Do I send my payment to the custom btc address in your signature?

I used my coinbase account and sent a bit extra from the pm price you gave.

thanks phil

I would also like to buy some of your 18 pin cables if you would be so kind to send it to the Netherlands?
I'm not in a hurry ,as you still have to order them. 10 cables would be nice.
Hope to hear from you.

It's pretty obvious that Bitmain will eventually release an "S7+" - already did most of the engineering for it between the S7 and the S5+.

 Has anyone actually tried running an S5 hash board on an S7 controller yet, or a S7 hashboard on an S5/S5+ controller?

How would it be possible ? S7 is not yet shipped.

S5+ blade works with S5 controller.

So a good chance they are the same, but we need someone to take delivery to confirm?

Rich

I have a day one order on the s-7 so with luck 10 to 15 days time I will have it.

they say first shipping = 21st of sept  which means  I get it on the 24th

sometimes they are faster  so maybe I get it between the 19-23 of sept.

Or Oct 12 -14

"Shipping may start between Sept. 21 ~ 30 (if shipped out 10 days later than it, it won't be considered as delay )."

Hi, if you have 3 S7, you don't need longer cables, try only to flip the 2 outside s7. The miners could seen like this:

F=S7 Front
R=S7 Rear

FRF
RFR

Then, you will not need to have longer cables, but you will need to switch the front fan to the rear fan ONLY ON THE CENTRAL S7 and ready to run!

You will still need longer cables.
View some S5 + image.

It would seem to me you could lash together two S7's with a single controller if you were to lay the miners on their sides, so that the "Top Side" were facing each other. Kind of awkward to wire up, but it shouldn't take any "long cables" to accomplish.

It would be interesting to know if the S7 cooling actually requires that the blades be vertical to work OK. While it's obvious what the "expected" orientation is, does it still behave well if it's laid on it's side?

point them upwards top to top that allows for  vertical and hot air raises.

stack them on a box fan  which allows for more air to help fans.  also if fans fail the box fan may save the day.

Still got some 16 pins left ill take 4 , or just wait ?. ....  btw

If I wanted to use 3 meanwell 450s bridged and running custom PCI connectors off those I could swing it i think... right?

let us know when you get more of those extension cables in stock those can come in handy I had an S5 controller board blow and I had stacked 2 miners on top of each other on 1 board but getting the wires in was very difficult to do with those short cables

If you have 2 S7s and they are laying at the shelf and mining for you, and then one controller will go down, you lose half of your hashing power. If you connect all S7's boards to one controller and it will then suddenly go down, you lose all your hashing power.

Think about it.  ;)

Better is to connect all S7's boards to remaining controller in case of one controller's failure as an emergency measure.

J4bberwock, I'm interested in picking up some cables too.

Since you indicated it will be about 3 weeks till they're back in stock, I'll ping you towards the end of the month.

they came and they are great.  i will write a trust later today.





here is a shot of my controller loaded for 6 boards.  so:

Thanks for the feedback, my girlfriend posted them without tracking, so I was a bit worried some won't reach the buyers.

I should have 200 of the 18 pins cables delivered in 8 or 10 days from now, if there is still some interest.

PM sent for some s5 cables.

Anyone has the Digi-Key Part Number of the cable connectors?

I´ve been looking like crazy on this section without luck:
http://www.digikey.com/product-search/en/connectors-interconnects

I would love to build these cables myself. :-[ :-[ :-[ :-[

I don't have the part number, but you'll probably end up paying more than the $1 I'm asking for each cable.
I'm making no profit on those cables.
To be transparent, I'm paying them $0.7 + shipping + 20% VAT on part and shipping.
I'm even probably at a loss if you add the time for packaging and actual packaging.

Now that there are quite a few S7's out there it would be good to have an answer to this question?  :)

Rich

I wanted to know this for controller efficiency. Basically it would be better to have less controllers for more miners. Keep the other controllers for backup.
And also, i can't seem to find the power consumption of the Beaglebone, did you calculate it yourself while you were messing around with the S5's? I'm guessing 10watts but just to be sure...

I measured it at 0.5A, so 6 Watts. This was by measuring with 2 hash boards Connected & then with 1 Hash Board connected. The difference is the current that a single hash board is taking. Multiply by 2 and take it from the number you first thought of  :) & the have the Controller current.

Someone else measured it at between 8 & 11.2 Watts. So it somewhere around there.

Rich

Yes.

Biggest S5, which is  been made.

S5 BBB with  S5+ software, S7 base plate with 9 long data cables.

Gotcha, based on your electrical knowledge and seeing how much power is available to the board, are you able to extrapolate how much juice it can give to fans without blowing up?


That put my 2xS5 project to shame. So thats with a S5+ controller? I would very much like detailed pictures of this, any thoughts on starting a thread and showing off everything?

For the long cable, i'm still waiting on Jabberwock to get back to my PM, i will definitively need a couple. If you know another source, i'd be interested to know.

No. It is S5 BBB with  S5+ software an  S7 (not S5+)  base plate with 9 long data cables.


This is only temporary for testing, so more pictures did not come.
It consists of 2 x double size S5 and another half of S5.
I do not know yet, what data cable slot should   left free,  to work with only  8x S5 blade.

Cables are from Jabberwock. Another option is  soldering them longer by itself.

For 8 board :

1 ) full
2 ) full
3) blank
4 ) full
5 ) full
6 ) full
7 ) full 
8 ) full
9 ) full

I didn't expect that, it wouldn't be possible outright based on what mine looked like. I mean the S5 BBB only has 4 slots for cables. Did you solder more in? Could be interesting personally to make a 3xS5.

What is What is BeagleBone Black?  (BBB)
http://beagleboard.org/BLACK

Oh right, for some reason i thought you meant a BBB with a S5 control board/plate etc. I hadn't realized that "base plate" was the thing the BBB socket in to control everything, my bad.

OK now that we have cleared up the definition of a BBB & "Base Plate" can I return to a rephrased version of an earlier question.

Has anyone actually tried running an S7 hashboard on an S5 BBB with an S5 baseplate?  :)

Rich

Yes.
3 x S7 blades  with S5  controller baseplate and S7 BBB with S7 software.

Hmm question was S7 hashboard on an S5 BBB with an S5 baseplate?

Rich

Why should I try this ?
S5/S5+ maximum Frequency is only 500M  and the S7 software is not yet available.
With S5 software you get 5/6 from S7 frequency and lower hashrate.

If you still do not know ,  S5+  and S7 BBB is exactly the same, the only difference is the software.

S5+ and S7 uses  BBB labeled as Model S5Bb/V1.51

I knew that they looked the same but for those of us who only have pictures was interested if they were actually the same and that you would be able to use an S5  BBB with a S5 baseplate with an S7 Hash Board? I am also assuming that the S7 software will become available at some point and that an upgrade for the S5 would be posible?

Rich

If you look at the image, it will not work very well with S7 software.
Lower hashrate and 6 phantom blades.

Would it not be possible to just save the json config with the 600 freq? I know the drop down menu only let you go to 500 but that list just feed the JSON its value. I don't see any reason whatsoever why cgminer couldn't handle the 600 freq if its manually fed that value.

If for some odd reason you need specific cgminer to do 600mhz, then you just need to replace the cgminer using shh.

I have no need to put the S5  controller work with S7

I get 2 free S7 controller each of the three S7.

And as it turned out of tests,  S7 controller works with 8 S5 blades.

https://i.imgur.com/m1cYxQ7.jpg (https://i.imgur.com/m1cYxQ7.jpg)

Do you have any experience running 4 stock fan on a single S5 BBB/Base plate? I'm thinking of making a 2x S5 and i'm worried 4 Stock fan running at full speed might burn the BBB if it can't support that much power?

Your input would be appreciated.

It is tested with S7 base plate with 6  fan  connectors.  4 Stock fan.
S5 base plate has only 2 fan  connectors.

But the S7 has a dedicated connector just to itself for power? Only 2 fan connector isint an issue i would use a Y splitter. I am just wondering whether the board can safely supply the power or not.

The answer is  -  not safely, not long time.

Okay, thanks, i'll try to figure out an alternative. Maybe either run 4 at half speed, which probably equate to the same load as 2 fan at full speed?

hi, are those, model ZPDR-18V-S ?

The easiest way to bypass all the fan issues is to run them at either 7v or 5v from the PSU.  It is easy to accomplish and very effective.  I think making a "custom" S5+ and using some inexpensive fans like the Yate Loons would work great.  Here is an explanation of running them at either 5 or 7 volts, which can be done without the switch described in the following article.

http://www.silentpcreview.com/article6-page1.html

I picked up 4 of the S7's and immediately switched all the fans to Scythe UltraKaze which are probably my favorite fans for a variety of reasons.  They spin at 3000 rpm putting out 133 cfm at a low 45 db.  Not the cheapest but last forever.  The last point is that they are great where static pressure is an issue, such as the tightly spaced fins on Bitmain products.  I can now be in the same neighborhood as the S7's and hear my family talking.

I'd rather find a fan that always run at full speed and does the job, since wiring shit is kind of annoying. Sound a pain since you can't feed the -5v back to your PSU. Or maybe use a resistor cable? Well whatevers.

I need those 18 pins cables first anyways.

Not 100% sure if it's the same cable on Alibaba. Usually there is a minimum order quantity and length is customizable for as low as $.25.
http://www.alibaba.com/product-detail/ul-listed-28awg-18-pin-1_1961042307.html?spm=a2700.7724838.30.10.MKLnMJ (http://www.alibaba.com/product-detail/ul-listed-28awg-18-pin-1_1961042307.html?spm=a2700.7724838.30.10.MKLnMJ)
 

It just take me to a login screen, and i can't find them on ebay using that name. If someone buy a batch, let me know i'd be interested. Even easier if you buy it to Canada. I don't know alibaba but if they can sell a batch and ship it to my address, maybe a 3rd party that know Alibaba could do the deal. Then it'd be easier to ship them out to whoeever need them.

But i'm guessing this is probably what Jabberwock is doing anyways so we can probably wait until he has a batch for sale.

Interesting, I loved the Kaze's with the S5's, but I've had pretty poor experiences with them so far with the S7... The stock fans for me are god-awful, one of the pairs resonates at high speed, and makes a really pleasant constant 'train whistle' sound - really adds to the whole experience.  At 55% the sound is gone, but still lurking in the background.

I'm in the process of designing a ducted solution to mount a centrifugal blower - I think I can use only one and get better numbers and even quieter than a single Kaze, plus the static pressure of blowers smoke axial fans.  The test blower I'm using can move 500cfm, but at the cost of static pressure and sound, but at more mellow values, like 200 cfm it's amazingly quiet.

My first pass is always to get a standalone solution, then I'll look to integrate the S7 into my big plenum case - the challenge with it is the fan I chose for it doesn't have the best static pressure because the S5's were so free-flowing, there wasn't a point - I'm not sure that will be the case with the S7's.  I'm also holding off to design it into the case until J4bberwock's next PSU design, since I plan to use that and incorporate it into the design as well.

did the scytre ultra kaze managed to cool this beast down? i have some of those around and i wandered if they can do the job with s-7. at full speed 3000 rpm what temperatures did you get?

waste of money this gear needs mufflers

read  this thread closely.  I have yet to use the home depot supplies. But the metal mufflers do work okay.

https://bitcointalk.org/index.php?topic=1188217.0

I would agree on the Kaze's, but the ducted blower solution I'm working on is another story - it's very quiet, but the proof will be once it's hooked up and actually performing, since I don't know how much air I will need to move with it.  I actually will be taking a first pass at it this afternoon, so assuming I don't end up needing to order anything I'll post some results.

Temp-wise right now I'm running them at ~60c, with the stock fans at 55%, or roughly 4000 RPM's... When I tried the Kaze's, I was seeing temps in the ~75+c range in the same environment, which was a no-go for me.

Hi
I'd like to order 6 or so cables fitting S7's when available.
Please let me know about details (shipping to Switzerland).

send him a pm

quick update 18 pins cables are now in stock.
I was unavailable for 2 weeks, so currently reading all the private messages.
If you have messaged me in the past 2 weeks, no need to send a new message unless I don't reply by tuesday.

I have 180 cables still in stock, so I hope enough for everybody.

I'm dealing directly with a connector and cables manufacturer who is making me those custom cables for the S5/S7.
I'm buying them with larger batches of my other supplies from him to save a bit on shipping.
As I said I'm not looking to make a profit on them, I'm considering it as a group buy.

Question: one miner=three connectors? Could you connect a total of three S7 to one controller? Or only two?
I also see that Phil used one short connector from the second S7, so only 2 long ones needed, right?
Therefore to hookup three machines you need four, not six long ones-am I right or not?
Thanks.

Yes. It is possible. But this miner together with 3 cubes with one controller is slower, as three separate s7.

Thats good, i'm still waiting to hear back from you. Please let me know when you get the long S5/S7 18 pins long cables. I'd also pick up a couple of 16pin long cables if those are available wherever.

he says ^^^^ that he has 180 of those in stock already.
https://bitcointalk.org/index.php?topic=1173573.msg12708774#msg12708774

shipping for multiple is expensive, though, maybe we better off if someone will get 50-100 in US, then we can get from that person. I am good for 4-6.

Last message he sent me was that he was out of stock, he has not replied to the thread saying they were on stock since then. But i saw he has a NA reseller, maybe he could send a Batch to him so we can get the cables for cheap.

Sorry, I didn't update everybody in private messages about the availability.
I'll send some to Finksy with other things by the end of next week, he'll dispatch them from Canada.
And he'll probably order some from my supplier if it's not done already.

So the miners will hash slower when running 3 off 1 controller? How about 2 miners on 1 controller?

When I connect my early B1 S7 hash board (with different housing than the later S7s) to B3 controller, the controller won't recognize the hash board and shows ------- ------- ------. But the hash board runs by itself with it's own controller. Any suggestions?

That is surprising. Can you examine the controller boards and see if there are differences / different Rev numbers on the PCB?

I seem to remember that the early S7 used the S5+ controller and that a difference with the Later S7 was that the orientation of the 18 Pin connectors was changed from 4 / 5 on each side mirrored to all 9 of the connectors being oriented the same way?

However I had expected to be able to swap Hash boards between Systems / Controllers?


Rich

So use space #1-4 for 4 boards, or leave a blank one in between.

Yes, board rev numbers are different, old one S7_SPOWER HashBoard_54_V1.3, and the new one S7_SPOWER HashBoard 54 V1.6

Edit: here is the pic of two boards, they are physically different, new one protrude at least 2" higher from the housing , old one is almost flushed.

"New" S5+/old S7 profile  and "New" S7

What about the Controller Boards, are they also different Revs?

Rich

Board dimensions might be the same, I haven't opened B3 S7 to compare, opened only early B1 because of 2 defective boards and of course with permission from BM. Here is a pic of early B1 and B3 S7s.

https://i.imgur.com/n9FWwCp.jpg

Controller board connector orientation is also different (where do I find rev #?)

https://i.imgur.com/vUndF0h.jpg

my batch 1 controller is running my batch 1 and my batch 2 s-7.  my batch 2 boards are marked 575.


they are running on 240 volt  using 9.9amps = 2376 watts and getting 4610gh

fans are 55% speeds are 3720 to 3960 rpm

errors are 0.0001%

it is 68f in New Jersey and I have them running a little under clocked on purpose due to the heat

https://i.imgur.com/CvtOXL9.png

Just going back to the original question. Have you tried a B3 Hash Board on the B1 controller?

Rich

I have 2 B1s and 1 B3, this particular B1 is different than other two hashboard rev and connector orientation wise. My other B1 is identical to my B3. Is your B1 similar to mine (rev V1.3)?

No, I haven't. My other B1 and B3s are hashing perfectly so I didn't bother to make any changes. This one is with only one hashing board so I tried to add it to one of the others while I wait for replacement instruction from BM.

Ok that's fine, don't go playing with Miners that are working and making Money.  :) It was just out of interest / to establish what works with what & why?

Rich

I will shoot photos tomorrow,

 but here is a second screen shot. compares freq 568 fans 55% to freq 581 fans 60%

I am still a bit heat challenged As it got past 70f today and has not dropped much.




freq = 581
fans = 60%
hash =9364
errors = 0.0018%

The new S7 software supports only 6 x  S7 blades.

I'm disappointed.

so my batch 1 with stock firmware on the controller just becomes more valuable?  as it can do 9 blades.

That is strange, I don't see the reasoning for that change.  My cables from J4bberwock will be here (Canada) on Monday, and my order from the manufacturer is taking longer than expected and will be another ~2 weeks in case anyone wants small amounts in North America.  I will update here and in my PSU thread when they arrive.

I never had 3 machines on hand.  So I only know the batch 1 does 6 blades  .

when you said new firmware only did 6 blades I assumed the old did the full 9 blades.


No one has posted an s-7 with more then six blades.

As far as I know  six can be done.  I would love to see a photo of 7, 8 or 9 working blades  on 1 controller.

One useful solution for S7 controller.

It works with S5+ software to control S5+ single cube / does not have control of the fan

It works with S5 software to control S5+ single cube / with  fan control

60% = 3,840 rpm
50% = 3,360- 3,480 rpm  (depends on the fan )

Working with ports 2, 3, 6  (left to right, viewed  by the end of the network cable side )

Not sure how useful it would be but... has anyone tried an S5 controller with the now released S7 Firmware. I have loaded it and it runs, but do not have an S7 to test?

just got my batch 3 s7, took me abt 20 mins or so to set everything up & to figure some other stuff out. running good for now.

fan set at 60%. fan 1 4080 rpm - fan 3 3840 rpm

chip freq set at 606

temps - 59-60-61

so far it has been running great.

compared to stock fans are around 4000-4200 rpm

it's a 600M sticker model v1.8

temps are 2 deg C cooler

with new 606 on the chips, 0 hw error hashrate is barely noticeable but a tad more. 600 on the chips (stock) 0.0001% hw error

1 thing i do notice that the hash rate does fluctuate quite abit regardless of chip freq settings. same on miner & poolside (antpool)

have 2 more batch 5 coming & hope that i can hook all 3 up but so far only 2 is reported successful. (darn should've ordered 1 more batch 5) so i can run 2 controllers - 4 miners - 6 blades each

gotta pm j4b to get the cables, psu and more pcie cables. i saw somewhere some guy power only 2 of 3 per board here in bct forum but i saw outside the forum , only powered 1 out of 3 pcie & it's working all week long. initially had some issues but when he moved the the pcie to the center instead of the sides & has been working flawlessly.

thx for the info filipma (name too long to type :p) ... let's keep each other updated.

My batch 2 is working like a true stud.
Freq 606
Errors 0.0001%

4910 gh

And boards are labeled 575.

My batch 2 is better then my batch 1.

I have found this gear wants hot psu's. By that 12.1 volts rather then 11.94
I have two evga 1600 psu's one is a plat and gives me 11.94 volts under a 1200 watt draw.

The other is a tit. Okay a titanium it is giving 12.1 volts  to the batch 2.

I think j4b has a way to do 2000 watt psu with over volts.

Maybe the s-7 thrives on 12.1 to 12.4 volts

I think that is a correct assessment, everything we have seen Bitnain doing with PSU spec 12V-12.6V, board selection, Frequecy reduction and finally reduced chain length points at the S7 wanting more volts.

A bit of good news is that server PSU's can more easily have their voltage adjusted up than down, by using the sense feedback voltage, usually at least 13V can be achieved. A lot of info on the RC forums as they always want more Volts.

I just hooked two units together via the rails and then unmounted both control boards and place a single bb board and data port board in between the two miners held in place with  a little velcro.  The original cables the S7 ships with are plenty long enough when set up this way... :)

thats what i did, works great.

thx for sharing the info guys but i noticed they do run slower than individual controller

how much slower?  4800 + 4800 = 9600  

are you dropping to 9500 or 9400 or worse?

I theorize the controller is running 4 fans vs 2  so that the pcie runs volts say 12.0 vs 12.1  and thus lower speeds.

I also think 2 s-7s on two controllers give two sets of psu readings  so if one psu is 12.1 and the other is 12.0  one s-7 will run better.

but 1 controller uses the lower reading so it reads the 12 and both s-7s run lower.

Phillip, wouldn't you think that the voltage at the chips (powered separately than the connector powering the controller) would have more of an impact on performance?  Maybe it has more to do with the amount of connections between all the chips and controller or something? I thought I remembered sidehack touching on the idea of communications between chips and controller and some limitations.

voltage is minimum of 12.2V & i might up it soon (12.5V) after modding psu's.

i can run 3 s7's with 2 x 2000bb psu but i'm running 1 x 2000cc per s7 so power is not the issue.

i think finsky might be right about connection between chips & controller ?

after i've modded psu voltage to 12.5V or more i will try again & see how it goes.

tests will be at stock speeds. 12.5V & 12.8V will be tested & see if there's any difference.

lucky for us, no need the long cables like the s5's to merge 2 in 1.

more ideas & suggestions, results are welcomed.

sorry for getting this old post up,

but after an thunderstorm , I got 2 controllers out of service on batch 9 S7s..

I don't have old S7 with controllers able to drive 2x3 blades , so I 'll have to buy new 2 new controllers (1 by damaged S7), or maybe 1 old controller able to drive the 2x S7s.

Would you guys advice me ? the best place to get some ? (cheap and fast ?) maybe another idea ? thank you !

i would love to know what i can do with these pin connectors

Can you test if it's the IO board or the BeagleBoner itself that is messed up? I believe the 'boner is the same on the S7 as is was for the S5 and S2 (but someone who can say for sure should verify that). If the IO board is okay, I've got a stack of the 'boners laying around.

You can use B.B.B. from S5 together with S7 controller.

Even S5 whole controller works with S7 software. (look at the picture S7 Batch8 2 blade with S5 controller)
 But as it turned out, it shows the wrong temperature. always around 46 C

Here's an off the wall thought for using PI's and Boners...
I'm currently playing with CryptoGlance for monitor software and in a nutshell, it sets up a Command/Control server on whatever PCish thing you have around. It's open source and loves Debian Linux. They have pre-built RasPi images for it. So...

How about cobbling together some some RasPi or BB plug& play cryptoGlance servers with them?

You want some to play with? I'm already booked solid on stuff I know what it is. And, to be fair, some of them came from your miners anyways. I figured on putting up a sale post sometime to get rid of 'em anyway, I got about a dozen.

Heh heh.. I already have 3 new-in-the-box Pi's from the A1/AMT days that I've yet to do more than open and look at.... Not to mention that I still have 6 more s5's and a couple s3's, s4's and even 2 s2's kickin' around. And the Demon of Time is at work here as well. :(

However, the cryptoGlance/Pi seems rather appealing so I WILL try it on at least one of mine. As for the pulls you got - sell'em off. You deserve the money.

Completely off topic, but "deserve" is one of my least favorite words.

Sorry. How about 'earned'?

Well , I think the IO is dead is one controler , and the BB is dead in the other. Because the effect was not exactly the same.
So I trid to melt the part , and now I have a controller fully ok , and a controller fully dead (with BB dead from one S7 and IO Dead from the other).
The good thing is I have one of the two s7 back in game , but the bad news is I have to get a whole controller unit for the second one now.

Any good deal somewhere ?

It seems that when using the S5 Controller with an S7 Blade that after booting it reads and reports a temperature, however no further readings are taken. If you boot from cold you get a low number, but if you then reboot after a few minutes you get a higher number?


Rich

I wrote too early , my rebuilded controller did not work for long , after one hour it stopped hashing too. I guess today small unexpected power shutdown got it burned too... ultra bad luck.
It is weird because the s7 is making hot air , but the green blinking led (for hashing) doesn't light..

So I think I still need two controllers ... or one able to drive 6 blades.
Thanks guys

any help to find controllers for sale ? I can't find it :-(

Are people still doing this one controller and 6 blade or 9 blade hack? I'm confused as some of the above comments make me think its not a good idea. I have a batch 7 that has 9 18 pin slots but came with the 162 chip board. Can I take the 162 chip boards out and put in 6 135 chip boards as long as I have enough PSU?

My 1st guess is that the BB's GPIO circuits can't handle the load of that many hash boards tied to it. Betcha Bitmain is using unbuffered BB' signals and that when overloaded it takes out part of the BB....

Since small computers like RasPi, BB, Audrino, et al are not known for um, 'robust' power protection, if the feed for the 3.3v used for GPIO is overloaded that could lead to Majik Smoke getting out...

Unless the IO board has a nice high-current 3.3V buck regulator on it, and the FPGA on there functions as an IO expander.

So... Will Batch 6 S7 IO board handle 6 S7 blades?  ???
