Lookin' sweet!
Ok, I'll wait and won't hack a hub to supply moar power for 2Pacs's/Compac... Wink
@ Biodom, yes, is a barrel connector for power. USB is coms only as I recall.

Well, ok... Teaser Tongue
Though I *do* have a 1.2kw ATX PSU under the desk feeding my R4 office heater and since the big PC 24pin connector only has a run-jumper in it, nice source for the (multiple) 5v to feed the ports and 12v for the hubs USB circuits via the existing regulator in it to run the hacked hub...

just wire it up to external 5V. If you want to power it with external 12V it'll explode because of all the 6.3V caps and also the buck controller is specifically made for USB applications so it only works between 4 and 5.5 volts.
Well, actually I suppose I could hack into the other Plugable I have cut the traces from the regs to ports and  feed the jacks from a 5v supply..

Was pretty sure the sticks were 5v only, ergo the ? on 12v. and ja, yer right about providing a high current jack. Ja the stick would love it but rather getting carried away... Wink

Ya know, looking at that USB bridge, something to be careful of is power hubs that use multiple 5v regulators to feed the ports. eg. my Plugable 7port 60w charging hub. Uses 3 regulators; 1 for ports 1&2, 1 for ports 3&4, and 1 for ports 5-7.

Point is, unless the system is setup for it regulators do not take kindly to be connected in parallel. Just as with mixing different PSU's to feed one hash board they will fight each other...

Just make sure the big honkin' hub either uses just 1 12v-to- 5v regulator or better yet a big 5v PSU or if it uses multiple regulators. If multiple, only bridge between ports fed from the same regulator.

Along this line... @ Sidehack, ever think about putting a 3 pin power select pin header on these? Keep USB connection for the coms side but for the Vcore regulator perhaps something like left-to-center jumped for USB powered or center-to-right jumped for using external 5v (or 12v?) via a barrel connector? Solves the whole USB connection limitation I'd think.

My latest s9 just arrived via UPS. Came up just fine and running 13.6TH/s.
Now just gotta hope that it continues to do so...

Und no - I am not about to risk one of my auto-tune s9's with the reset trick....
4506  Bitcoin / Hardware / Re: Where can I buy antminer s7 new? on: March 25, 2017, 11:06:40 PM
Do you guys know a legit page that sell them for $400-$500. Electricity in my country is free and im trying to build a little setup. What do you recommend me?
The s7 has been out of production for over a year. There are NO 'new' ones.
I would look into Sidehack's offer of proven used ones.

Am searching high and low for Prospero X-1 or X3 that are nonhashing but have good LCD parts. Does anyone have anything out there?
Best option is to just replace it with a new one... Odds are it is commonly available from ebay, DigiKey, etc...
For starters, what kind of controller does the miner use? Is it a RasPi? Find that out and then google LDC display <controller>

i've also included some kernel log details of Incorrigible but not sure if its useful.
really appreciate your feedback.
thank you so much.

After decades of me being the um, only technical brains, of our company we finally hired another EE last year. I'll give him an 'A" for enthusiasm but as far as any understanding how to actually apply whatever he was taught in college...  Roll Eyes Then there is the issue of hopefully passing on to him at least *some* what I've learned over the past 1/2 century +...

First thing I did was give him my ancient dog-eared copy of The Radio Amateur's Handbook I got in 1965 when I was 9 to fill in much of what should be Electronics 101 but was never covered in college.

With both miners you can't access the GUI page or just the 1? If you are on the right address and never connect then the controller and/or BeagleBone may be dead.

Normally I'd say ja the voltage looks good and actually much higher than expected under load. What is the voltage with no-load? Even my IBM 2kw supplies max at 12.2v no-load and drop to 12.1v measured at the plugs @ 1.3kw load. Does the miner ever start blowing hot air? If no then it is never hashing.

Query: What batch are the miners? Batches 1-5 use 54 chips and have no Vcore regulator. Voltage per-chips is PSU supply divided by number of chips. If you look in the hot end all you see are heatsinks.

Batches 6 on up all have 45 chips and a regulator. Look in the hot end and you will see an open area with the circuits.

The post on Plugable's 7-port charging hub power setup is from me Smiley
Possibly using Y-cables is contributing to the drop out?

I run 2x 2Pacs and 1 Compac on the Plugable 7-port 60w charging hub.
For form-factor and cooling I have a 2Pac on port-2, the other 2Pac on port-4, and the Compac on port-6. Nice and compact for cooling and each stick is on its own buck.

Tried running them without the y-cables, just plugged straight into the hub?

<snip>
After the initial warmup (running sticks on stock vcore and 100Mhz), I upped the voltage to 1.50 and started increasing frequency. One stick chugs nicely, the other one dies. Then I upped the voltage on the second one a bit more (can't be sure if it was quarter turn or half a turn) and I just measured it at 1.63 - I'm talking about string voltage (as described on an image posted earlier, I believe, in this thread). ASIC voltages are, what is expected I guess, half of that. Since my last post I lowered frequency to 200Mhz, but nothing changed. One stick works, the other one works for a while then commits suicide Smiley

BTW, Compacs had reset pin marked. I tried locating it on 2Pac but failed.
Try swapping the sticks between the USB hub ports. Does the same stick take a nap or does the fault stay with the same port?

^^ and go to a hardware store or wherever and buy a voltmeter. Doesn't have to be expensive, just has to be digital so you can see at least 1 decimal point or more. All Ants need at LEAST 11.9vdc feeding them as measured at the PCIe plugs.

Poke the probes into the sockets alongside the wires to avoid shorting anything.

If using Windoze, you *did* dl and install the Zadig USB driver right? CGminer requires it for all USB linked devices.

I thought that was the inductor (copper coil with magnet in middle) and the PIC is lower down to the left ?

Ref your pic, is not a magnet, is a ferrite core for the inductor. The regulators run around 50-100kHz and iron laminations are useless at those freq.

I believe the PIC is on the other side of the board off to the right of 3 other larger chips. Follow the traces from the 6-pin programming connection. I have a s7 board pulled and will take it into work tomorrow to look at the actual chip numbers with a microscope. DAMN that writing is tiny .

EDIT: Just looked at the chips under a video scope and you are right. That little chip U3 on the inductor side of the board is the PIC.

Was hoping for a hell of a lot less compiling to get these going, don't do much of that.
Will give it a shot.
Or fire up an old Windows pc and use it as the Host. There is a ready-to-run Win binary for it...

I do hope you caught https://bitcointalk.org/index.php?topic=1504228.msg18293399#msg18293399 right after Sidehack's reply... Your s7 does not have the regulator talked about in this thread nor the 'Cheap and simple repair of S7 hash board' thread... No big honking power inductor (and 54 chips) = no Vcore regulation.
4518  Bitcoin / Hardware / Re: Hacking the S7 - improving efficiency through minor hardware manipulation on: March 22, 2017, 05:14:05 PM
Remember when I mentioned you should do some research on how buck regulators work?

Note also the explanation in the first post. The PIC sends a signal to the digital potentiometer tied to the buck regulator, and that adjusts the voltage. Remember how NotFuzzyWarm told you to measure your voltage at the big inductor?

Note how in this thread there's talk of using a PIC programmer on the 6-pin header. That's because the 6-pin header is ONLY USED TO PROGRAM THE PIC. There is no measuring of voltage going on there. The voltage people are referring to (~9V for a dead PIC, >10V for a working one) are measured at the buck regulator output. That's been stated multiple times in this thread and the potentiometer fix thread.

Also note that the 8-pin SOIC I told you to look at says "1572" on it. That's the PIC12F1572.

So what you do is exactly what's been told to you so far. You fire up the board (make sure it's got 12V power and is plugged to the IO board by the 18-pin cable) and measure the main buck regulator output voltage (at the inductor). If it's around 9.3 volts, your PIC isn't setting the voltage probably because it's dead. Buy a new one, flash it with the firmware given in this thread (aaron6 linked you to it) and then power up the board again, see if the voltage is better.

If you power up the board and it's reading over 10 volts, this is not the fix you need.

I have red up on buck regulators, ant that the PIC is just a digital pot, and people are just replacing it with a standard screw pot.

What i don't know is where the 'BIG Inductor' is even after reading his thread ?

When i have replaced pics in the past i have always programed them via my PIC Programmer, just plug it into the correct slot/position on programming board and 'flash it' with the  FW aaro6 linked me.

I tried to find a pic with '1572, but not ecen my usb scope could pick it up, why not just state it is labelled U3 on pcb, and the 6 in header linked to the pic is P1 and the GND P2 ?

I am still reading the threads and looking on how to 'measure the main buck regulator output voltage (at the inductor)' Huh

Why does a blank i need to flashed via the 6 pin header?  Never seen tha done beore always used a PIC prgrammer board and relevent program....
Cheers
I think you have one of the very early batch number s7's... They have no Vcore regulator, the ASICs are directly fed from the PSU.

I think we kit a key point about the s7's - and s9's: What batch number is it? With the s7 batches 1-5 with 54 chips per board have NO Vcore voltage control. ergo no DPOT, no regulator chip, no inductor, etc. and I think no PIC. Only the later batches with 45 chips have the Vcore regulator goodies...


All the chips are in 1 big series string with Vcore set by how many chips in the string divided into the PSU supply voltage. As with any string topology, any break in the string from a bad chip or bypass cap and the whole board dies.

A decent read on buck regulators, https://en.wikipedia.org/wiki/Buck_converter
4519  Bitcoin / Hardware / Re: Hacking the S7 - improving efficiency through minor hardware manipulation on: March 22, 2017, 01:36:33 AM
Well for a start, what is the voltage into and out of the big power inductor? One side should be fed from the PCIe plug through MOSFETS and will be a chopped 12v, the output side needs to 10v or more depending what the PIC is setup for. (Sidehack confirm?) Somewhere in this thread the output is mentioned.

Anyhow, if the low side of the inductor is less than that, probably dead PIC and the regulator/dpot is working off of preset defaults. If the voltage is zero the I'd guess the FET's failed open but typically they fail as a short.

I suppose if you have a PICkit programmer you can follow the heart of this thread and try to readout what the PIC has stored in it. After saving that (possibly corrupt) file might as well see if the PIC can accept a reprogram for lower voltage better eff...

Well, PM Sidehack about it. You seem pretty on-target with your questions so I think you can learn much about the s7 power from him. Specifically, information on checking voltages (and changing them). Tell him I referred you to him Wink
