[GUIDE] BitFury Miner Support/Tuning

[zurg]

Ok guys, I need some assistance

I had an August kit with 2 boards (~47Gh/s)
so the M-Board is V1.0
on Friday I got 10 more boards and placed them 1st in-line then added my 2 pre-existing boards with last board being EOL one.
All this was powered by a 1Kw PS that died on me Sunday evening.
So I had it running about 48 hours.
All the new boards are stock = not overclocked.

Now I placed a spare 430W PS on the BF rig and it runs, however I can only see 96 chips running = 1st 6 cards.

Any ideas why it doesn't see the rest?

Thanks

  you can do test on pcb that mboard did not see if it's working ok by itself.

Looks likew the card ain't working RMA time

What test did you do to determine the card wasn't working?

I tried the card just by itself and actually changed it's position in the chain.
Didn't matter where I placed it, as any card after it was not showing at all. (including this card)

Okay, thanks. That will be helpful to remember for future troubleshooting.

[cypherdoc]

ok, now it's happening to me; again.

absolutely no hashing with one of my 14 card rigs.  changed out SD cards and raspi.  can login into admin page but no hashing.  took rig apart and checked for any burnt boards (none) and blew out M board connector in case of excess oxidation (none apparent).

what were all the suggestions given for this frequent problem?

I've said it many times before, so I'll let you scroll up for details, but you need to check the output of chainminer and the proxies.

Can anyone tell me how to disable that chip in bfgminer? I have tried using 53, 54, etc. and I keep getting the above message. Other than that everything is fine. Thanks!

Hmm, that hasn't happened to me yet, so I don't know what's the problem. It seems the chips are getting work but are returning tons of bad nonces and other errors. Is this a multi-bank M-board? My first thought is a bad connection, but it's too coincidental for all banks to do that at once. Maybe one of the voltage regulators on the M-board went bad? One should be ~1.8v and the other ~5v. The 5v just powers the rPi, so must be ok. But I can imagine bad 1.8v for chip comm causing weird results like this.

Hey guys,

I'm sorry if this has been asked a thousand times already, but I have RTFM and OP, and I see nothing about cooling.

My H-cards came with heatsinks. I don't want to OC the chips at this stage, and my ambient temp is around 20°C.

Can I start hashing without active cooling (i.e. fans), just with the heatsinks? The photo in OP doesn't even have heatsinks.
Or is it so obvious that you shouldn't run these without fans, that it's not written anywhere?

Thanks guys! I sold off my CEX.io GHS to buy these, it's just cheaper for more hashrate. Yay!

You'll need to aim a fan at the rig.  Chips run hot and need blown air.

Thanks for your answer!

As I didn't have any spare fan left, I used the one of my BE Blades to create an air tunnel. Air blows to BF first, then the Blades ;-)

It's happily hashing now. I guess there's no thermal probe onboard as I don't see any temp reading in the web interface, right? So I guess I should just do as for the BE Blades, stick an external probe on one of the boards

[zurg]

Well, I am at a loss of whats going on with my setup.
Got replacement card and the rig been mining about 12 hours.
Now I get notification of hashrate drop. I login to see a few of the cards at Zero.
Reboot Pi and only first 3 cards are hashing.
My room is at a constant 60F with fans blowing over the cards.

Set all chip speeds to something slow like 50 with autotune off, and restart chainmminer. If the problem persists, reseat the cards.

Just got to work and shut the miner off.
I moved it and realigned the fans etc...to be sure that none of the cards are vibrating.
All the boards started up...
Guess I'll have to keep a close eye on them and have my laser digital thermometer at the ready.

Now praying for this 1 day 14 hours block to be finally solved. lol

So I get home today and only one of my 8 cards is hashing. I have no clue where to start. The outputs are below. The stratum proxy looks good, not sure what happened and why the other 7 boards will not work. I have re-seated all the cards, tried rocking them, and moved them around to different slots. Anyone have anything else I can try?

Edit: Narrowed it down to 2 bad boards. It appears the solder on the pins has worn down and the cards are not getting good contact on the M-board slots. Not sure how to fix that.

I have a board that has gone from 450 Gh/s to 135.  I have tried everything and can't get more than one card per four slot bay.

When some of my cards quit showing up I powered the whole rig down and about 20min later powered it.. all the cards were showing up.
Make sure that none of them vibrate if your fan is blowing on them.
Also try pulling the 1st non working card and move the rest up. I had 1 card go bad like that and it made the rest of them in the chain not show up at all.

I will try leaving it off for 20 min. My issue is that the first slot for each bank works, ie:0, 4, 8, and C. The rest are not working. No clue what happened.

ventilation and power are key with 90% of hashing / card issues.

If you don't have a fan pointed at your cards, they will overheat and shut off.  Turn the rigs on their left hand side (so the SD card is facing down) and aim a good sized fan towards it.
