1  Bitcoin / Hardware / Re: BFL Product Failures / Underperformance.- HELP on: December 02, 2014, 01:24:59 PM
HELP!!!! I have 4 BFL SC 60 GH/s machines and would like to use my own ATX power supply (instead of their fireboxes)  to power them.  I have no clue how to do this.  Do I need a separate PSU for each miner, or could I use, say one 1000W PSU and run the 6 pin PCIe cables in a series, using splitters? Once I plug in the 6 pin PCI-e cable (2 of them) into the miner, do I need to do anything with the other cables coming from the PSU? I am very anxious to start mining, but I don't want to burn my house down, like that Mining facility in Thailand a few months ago.  Any help would be greatly appreciated.

Thanks,

John
With 4 singles, you would need at least 1 1500W or 2 750W power supplies to safely run them.  In addition, you would not want to use a cable that has more than 1 6-pin PCIe connector on it's length.  An EVGA 1500W supply has 8 PCIe connections available and thus could run 4 singles using 8 cables that go from 8 pin to 6 pin connectors.

I implore you to find where I've said anything that says bfl is good in any way for, well, anyone or anything. They can burn in hell for all I care.

Just because we're sticking strictly to the forum rules doesn't suddenly make us some kind of dick sucking manufacturer lovers. Heck this BFL fucked us over thread has been allowed for as long as I can remember...
Where can the forum rules be found?

Ok. Well I got the new FETs in and decided to take the old ones off this board. Symptom was a .3 ohm resistance on the 12 volt line instead of the normal 300 or so ohms.

Started pulling FETs, then found they were not coming off. Fuck these things are small. Too small for my normal picker, I'm going to need a special nozzle. Then I realized my pre-heater was broken.

*grumble* Took pre-heater apart, wire had broken at the phenolic junction between normal wires and the nichrome type wire in the heater. Fixed it, back in business.

Here's a little thought if you think you can burn these FETs off with just hot air: Forget it. In order to remove them without damaging the board, you have to take the board to 380F pre-heat, then sit on them at 450c air for *30* seconds each. Say what you want about the board, but man does it pull HEAT away from these FETs.

Started pulling, did the left 6 and no change to the resistance. 7-10 same thing, started feeling really grumpt because I have to PUT THESE BACK! Then I did #11. Instantly resistance went to 300 ohms. And the underside of the FET was bad. Looks like I found the bad one.

Now to let things cool, then put on new fets tomorrow. I'm going to need flux for this one, these are going to be hell to solder back on. But do-able, and I have now proven that FET shorts are what shut down power supplies.

On ward. We're getting there. By the way if anyone else wants to follow along give it a go!

C
If you want to invest a little in equipment, I'd recommend a thermal imager. They're incredible tools for debugging these kinds of problems since they can detect <1C temperature differences. Solder on a couple wires and use a current limited power supply, and you can see quite quickly which fet is the one that's shorted.
Along these lines, if you have a constant current power supply and apply ~2-3v to the PCIe pins you can see the shorted FET glow under IR, saving the time and trouble of removing good FETs.

So... who has been lying now Josh? 90%? Really show me where I lied once?
I can easily show twice:

Never mind I don't really care. Back on ignore peon.

This is my last post about Josh and BFL...

Then there's the whole "I'll buy $2800 in BTC if someone shows proof they bought a Monarch" where you then showed a $161 purchase of FRC.

Check and mate.

The 11.5-16VDC seems to be when plugging it into e.g. a car's power jack (cigarette lighter), sometimes also found on airplanes (first class, maybe, though I think those are all standard outlets now as it is), and has nothing to do with output voltage.

It likely is 19V output as stated on the back (manufacturer probably knows better than the people who wrote the documentation/packaging/promo fluff) and at some retailers (e.g. maplin) who didn't just copy/paste the material, and that would explain the fan going faster than it's supposed to if that's pretty much just hooked up (semi)directly.

The jalapeno's mining portion itself is behind a bunch of voltage regulators, so that should be okay.  Those voltage regualtors themselves may run hotter than they're supposed to, though.  They may well be able to take it, but why take the risk?

Find a proper 12V brick.  You can find plenty for cheap with plenty of oomph: 12V 5A, 12V 6A is fairly common as LCD monitors use those a lot.  You can't use those as a travel power supply, but if you're buying something for that secondary purpose, you can do a lot better than this iffy thing.
5 or 6 amps is only workable if the Jalapeno is 5-7gh.  The 3 chip Jalapenos need a 10 amp supply.

I wish I had an answer for you on underclocking.  Have you tried running the faster one off of BFGminer yet?  You mentioned a speedup with CGminer on your 550, I'm curious if it will run slower and cooler and if there is as big a difference in speed on the 700. 
Very odd. First time ever that on default clocks that if my software runs faster people are looking for ways to slow it down. Let it be known that BFL never informed us of any messaging protocol to over or underclock the devices, so I can't see how we could even implement such a feature. If it runs slower at the same clocks that implies a software limitation.
You would have to ask Nasser about that, I know he talked about it.
Nasser was on my skype list and I emailed him a few times and got the latest and last set of protocols, and last we spoke we discussed a way of rolling work on the device. There was never any mention of clocking commands, and the nroll-time on the device never eventuated, though this was actually months ago now. Sorry but as far as I can see all development stopped a long time ago on the mofarcher.
Since we never got a working version of CGminer, I only have second hand information that it seems to do a better job communicating with the Monarch compared to BFGminer, resulting in several people talking about speed increases.  The 1.4.2 firmware has the capability to accept underclocking commands and I helped test it.  Adjustments could be made to both voltage and frequency that would work until the unit had power cycled on it.  I know from experiance that above 530 watts at the wall that heat becomes a major issue, so it seems that your programs capability of making them run faster is a dual edged sword.

If you have a board that is running at 800gh and pulling 570 watts, you are getting close to the limit for the PCIe connectors.  To try and cool it off I would recommend trying one or more of the following:  1) more powerful fan on the radiator (stock is ~.33-.5 amp, try to find a 1 amp or bigger)  2) point a fan at the VRM (the space between the pumps)  3) find a cooler location for the unit.  I'm curious, are you using BFGminer or CGminer?  I know there was talk of commandline underclocking of the units, but I don't know if either program has it implemented as yet.

I'd rather underclock it instead of trying to desperately cool it generating tons of noise in the process, but I'll see what happens. I'm using cgminer 4.6.1 on Linux.

BTW, these units seem to get excited and run faster and hotter with a powerful PSU instead of a weaker one. My 550 GH unit runs cooler and slower (650 GH/s, 420W) when I power it off my 500W Super Flower PSU instead of the Corsair TX850W (690 GH/s, 470W).


EDIT: Swapped the Corsair TX850 to TX750 just now. Why? I don't know. And I put a fan blowing towards the power parts http://i.imgur.com/JvVzNII.jpg

GH/s went down a bit. Power draw 550W. Temp at 70.00C after a half an hour and no thermal throttling so far. So what I got with my two Monarchs is 1.45 TH/s for 970 watts which is not bad, but I'd still underclock the faster unit for less heat and noise. Although the two combined are still more quiet than a single Antminer S3 underclocked to 420GH/340W.

So I did what any crazy person would do and bought me another Monarch on wednesday. This time it was a regular auction on ebay. 230 pounds / 290 euros, so a tad cheaper than my first "550GH" unit.

The board seems to be a different revision. It's a "700 GH" model with a mini-usb connector (which the 550 GH model didn't have) next to the pci-e power connectors.

http://i.imgur.com/Itspqdq.jpg

The problem is that it's running too hot, above 80 C and the board starts throttling after only a few minutes of running. Power draw is 570 watts from the wall at 800 GH/s.

So it would be great to have a method to underclock this thing as I don't really need the extra GH/s with a bigger power draw and overheating.

By the way, Raspberry Pi with Raspbian OS and cgminer 4.6.1 seems to run two Monarchs just fine. CPU load is ~0.40.

Honestly, that is way out of my comfort zone. Its defiantly not leaking any more. When I plug in the monarchs to the PSU I hear that electric buzzing sound like a short. Then the PSU kicks off only way I can restart the psu is to remove paper clip and put back in. The connections on the monarch look good and it does it on both my 525 and 700 monarch. I've mixed and match PSU to my other two monarchs and its not the PSU. Thanks for your help.
If the psu kicks off like you said and these are the ones that leaked, I would bet that one of the FETs blew when the board overheated and pulled too much power.  If you have access to a multimeter, check the ohm reading on the PCIe connector(front row vs back row, not side to side) and see if it is nearly shorted (<.3 ohms).  A good unit will ramp up to several k ohm and then start back down.  The minimal ohms indicated a blown FET.  I'd say to RMA it, but I have no idea when it would be taken care of with the current situation...
12  Bitcoin / Hardware / Re: {BFL} Here's a LOOOOOOOOOOOOOOOOOOK at your Monarch! on: September 16, 2014, 11:52:39 PM
I hope that's not the 700GH/s Monarch showing 270ish Watts of power.  It's got the same size fan as my 700 with the 450 being a much smaller fan and heatsink.  It's the 450 that produces that Wattage! The 700GH/s Monarch is pulling around 500-550 Watts.
That is a 700, and you are not reading it fully... 270 AND 210 = 480.  Or did you miss the second readout?

Also what speed is being reported by Eligius? Say the 22 minute numbers, do they match the lower or higher of the 3 BFG numbers?

The pool is kind of the final solution on speed, you're not getting rejects so I'm curious.
22.5 minutes 809.57 Gh/s 254464sh, went for a drink, refreshed the page, and....22.5 minutes 765.59 Gh/s 240640sh, next refresh and the same 22.5 minutes   809.57Gh/s 254464sh again.

I never considered eligius' status page to be accurate, is the 22 min. number any good as a reference? BFGminer low shows 776, mid 807, high 854 and up till 940
BCP both units have the solid on led, that goes on/off when hashing. One has a second led just below the first one, it blinks fast about 6 times (so fast it's impossible to count the actual number), then it goes off for a sec., it does this from powering up, and keeps doing it. There are more leds, just noticed 1 or 2 between the pcb and the copper plate, solid on, I see the reflection on the sledge's base plate under the right chip.

Lightfoot have you tried getting anything by jtag, or is that what you got as said earlier, with chiliflash?

Ognasty, I restart the pc and miners every time I make a change or after a shut down bfgminer, shouldn't be a problem there. The fan on the fets made no change so far, after 6 hours hashing.

edit; no time for the utp now, but I doubt it will change anything.
There are actually 4 lit LEDs under the water block there (7 total LEDs), they indicate good voltages present for 5.0, 3.3, 1.8 and either 1.5/1.2 volts.

As seen from the data you uploaded, you have a board with 'B' chips on it as the engine counts are roughly 800 engines per chip.

There are 64 'tiles' per chip and 16 engines per tile for a total of 1024 engines per chip.  I've not run across a pair of chips that have all 1024 running, I think the closest was around 2028.

14  Bitcoin / Hardware / Re: Hacking BFL Monarchs to.... Just bought one, we're going to find OUT! on: September 12, 2014, 03:23:15 AM
Do you also see messages like "sanity check, device is processing unknown work, device is missing queued job. device flushed (goes by too fast), failed to find work for queue results" in the bfgminer cmd window?
Interesting. When I first powered up I got a nice 700gh. After an hour I shut it down to switch power supplies, fired up, and saw some error messages and about 600gh speeds.

Shut it down, went back to previous supply, started up. Same.

This afternoon I shut it down, let it sit for 20 minutes to cool off, powered it up. 700gh, no errors I can see (I don't stare at it, just check every once in awhile). Solid as a rock.

One odd thing: I did notice the power supply high pitch frequency from the chokes was different. Maybe when the board is cycled hot it does a similar thing to what the old Singles did when they would power up more slowly. But letting it sit for a few mins seems to have restored it. Note it's been running for 6 hours now without a problem.

What are you seeing. Can you post the messages? Do they all do that, can you try shutting off the one that does for 15-20 mins? How does it hash?
C


posted this on bfl forum too, edited to today's findings;
"I'm getting errors on 1 of 2 monarchs, switched usb cables, ports, tried powered usb hub, un-powered, direct into pc. I noticed on powering the monarchs, one has a 1 red led going on/off/on/off etc. near the back usb, the other one with the errors has 2, one with the same on/off sequence, and one that blinks fast about 6 times, then goes off for a sec., then blinks fast again, etc.
errors are:
"sanity check, device is processing unknown work,
device is missing queued job. device flushed (goes by too fast)
failed to find work for queue results", then it hashes a couple of shares, and the same errors pop up again, and this repeats itself over and over, on the same monarch."

Later noticed they occur on bfl0 and bfl1, probably normal, I don't know if those messages in the command window are new for bfgminer 4.7.x and higher?

later

"Yeah, switching psu/usb/cables with the other one brings no difference, what does the fast blinking led next to the once-per-second flashing one on the error one mean? Even when it is only powered up and not hashing, it shows the same fast blinking of a second led. Doesn't look like I'm missing out on much hashrate though, it's running as it is specced, over 790-840GH for 2x 400GH rated units."

Actually a 400GH and a 425GH unit, and labelled so on the small fan's side. BFGminer reports couple of degrees above room temp, more shed temp, running about 22C. Odd thing is I found bfgminer shut down 2 times now. I'm kind of busy and don't have time to sit down with the miners and host and the bfgminer manuals to see what's to adapt, but I guess overclocking goes by fw like the sc's did?
And 5% and 4% hw errors btw, 0% and 0% rejected.

Just an FYI, the light below the blinking one (which indicates ASIC initialization when solid, hashing when blinking) is related to the FGPA.  In the older code it was off, in the newer code it has the fast blink then off on a ~2 sec cycle.  If the FPGA is erased, it lights dimly.

Have you seen the 4.2.0 custom build BFG on the BFL website?  I know it doesn't seem anywhere near as prone to the sanity checks (unless you stop/start BFG without cycling power on the card)  The FPGA buffers the work done and submits upon BFG restart and you get a mass of work not found.  This buffer send seems to cause BFG to hiccup as I see an occasion 'failed to send queue' which goes away if I then cycle power on the card and restart BFG.

Five 30A x 208/240V drops terminating with Nema L6-30r  receptacles.  Get Some PDUs to plug into those.  Save
the last 10A of headroom for some huge ass fans. You'll need them.

Why would you want to use 120V?  PC power supplies can run on either.  240V is more efficient, cheaper, and puts less stress/heat on the power supplies.

This is exactly what I was looking for, I think. When you say the pc power supply can be run on 240V, are you talking about using the PDUs that others have suggested or something else? I can't plug them directly in as the plug doesnt fit in the Nema L6-30r.
You use something like this to power your PSU's:

http://www.buypdu.com/power-cords/iec-c13/iec-c14.html?gclid=CPLX_vTu-78CFWwQ7AodfRcA9w

Depending on the PSUs you are running will determine if you get the 10 or 15 amp version (though in truth, at 208/240v you will only need the 10amp).  The Triplite PDUs are set up to use these cords and will work with any EVGA/OCZ power supply.  A typical PDU can be found here:

http://www.tripplite.com/metered-pdu-30a-208v-240v-2u-c13-c19-outlets-l6-30p-single-phase~PDUMH30HV/

Remember, it's more efficient to use 208/240 versus 120 to power your equipment.

Hello All,

I purchased a Butterfly Labs 30GH from Ebay.  I did not go into this blind.  They told me that it was DOA, figured for 25 dollars what the heck.  What I found was a burn spot on the PCB board right below the asic and right above R40 and R42.  Looks like the placement was C11?.  First does anyone know what this is on the board?  Can it be fixed?  I sent an e-mail to Butterfly Labs asking if they would RMA it since it was the board.  We will see what they have to say.  Otherwise just getting ideas on what I could do.

Thanks for any help.  Let me know if you would like a picture of the board. For additional info.

John
Did you email directly or did you use the form on the website?  http://butterflylabs.com/technical-support/ is the link, make sure you mention that it is a 3rd party RMA.

Yeah the only one I have but my son has one too. I got two when I ordered mine. One for me and you guessed. My sons worked out of the box but mine has never functioned correctly. I tried as you suggested Thomas. No joy sadly, though I did manage to make a connection to both Slushy's pool and Eclipse but the unit never hashed anything. That was the first time it has managed to do so. I now believe I got a none functioning unit.  Cry
Have you tried connecting your miner to your sons computer and his to yours?  That would be the quickest and easiest way to tell if there is a problem with the unit or the computer.
