[GUIDE] BitFury Miner Support/Tuning

[spiccioli]

Do we know which chip is which # in the .stat.log ?

Sure,

you have [board:chip] on every line and on the board chips are numbered from 40 to 4F beside each chip.

Chips start in the lower left corner, connector facing down, go up, then down, then up, then down again reaching the lower right corner of the board.

Hi guys,

did someone know were i can get an original image with the bitfury miner for the sd card from the raspberry?

best regards

[-Redacted-]

See the bottom of the OP, or read back about 10 messages.

[greaterninja]

i got my starter kit hooked up,


1.  green and black atx motherboard connector jumped
2.  sd car in RPI
3.  2 x 6 pin PCIE power cables on the M-board
4.  h card in slot 1
5.  ethernet cable hooked up.
6.  h card components point toward the Rpi



the rPi powers up, i can see a Orange, green, green red  light  and I feel heat on the h-card.


I cannot ssh or ping 192.168.1.249.

I do not see any new ip addresses on my router as well.


What am I doing wrong?

[-Redacted-]

Probably nothing.  The RPi is likely set to a different subnet than your router.  You may have to use keyboard and monitor connected to the RPi to change the interface file to an IP that matches your network.

[greaterninja]

my network is 192.168.1.1 gateway
255.255.255.0 subnet


Aaaah man i really do not want to hook up a hdmi cable.

I was wondering the same when I found out that the rPI got an IP using DHCP

If it was using cgminer with --api-listen --api-network --api-mcast
Then you'd simply send a multicast "java MCast" and it would reply
... oh wait ...

turns out i had to hook it up to the tv via hdmi.   when i logged in it was still setting up the network adapter.  It asked me what IP i wish to set it as.  After that I still had to manually edit the gateway ip, and subnet gateway.   after restarting the gateway worked.   I want to also note I checked my router for any attached devices prior to this to see if there was any broadcasting IP address.  It found nothing...no mac nor IP.   This is on the 9/19/2013 bitfury I received.

Ok, i need help.   I have a starter kit  with 5 h-boards in it.

The web interface shows   132GH/s.  However slush's pool only shows 15-21GH/s after several hours.


What am I doing wrong???


Should I only put 4 boards in, spaced on channel 1 of each of the 4 quadrants??


I just got this kit less than 24 hours ago...I gotta be doing something bad.  Please help guys.


Thank you

[Micky25]

I understand the excitement, stay cool

Did you have a look at the FAQ / first steps? https://bitcointalk.org/index.php?topic=287590.msg3079405#msg3079405
Please keep in mind that there a different approaches for US and European units.

And don't forget to adjust the difficulty on the pool.

This is a problem with Slush - it oftens takes some time and retries to get working properly.

• Set up three different workers on Slush, using difficulty 16.
• Point each of the three web proxies to Slush using port 3333, but a different worker for each.
• Stop the miner and wait until the noncerate goes to zero.  
• Restart the proxies.
• Start the miner again.

One board in each of the 4 channels a-1, b-1, c-1, d-1.  Your 5th card should go into a-2...

My stuff is working OK on Slush with two cards:

Name                     Shares                       HashRate
rsb.work_01       37562    (37266)       15309    (15364)
rsb.work_02       41064    (40800)       16736    (16821)
rsb.work_03       46024    (45320)       18757    (18685)


NB:  Your hashrate on Slush will usually be 10% under the nonerate.  My two cards and three workers generate 10% dupe submissions...

Anyone getting over 500GH/s with a full rig?

[kaerf]

Has anyone had an Hcard that doesn't get detected? stat.json doesn't list it at all.

I had 1 card that went out like this and now I have another one....the chips still heat up, but chainminer just doesn't detect any chips. I've tried plugging it into other Mboards and it still doesn't get detected . In the past, reseating this Hcard after a few tries magically made it get detected again, but not this time. 

[Micky25]

plugged it in the right way dude?

[kaerf]

plugged it in the right way dude?

yes...it was working fine, then nadda.

[kaerf]

the first chip on my bad board is much hotter than the other chips. maybe the first chip is bad. i'll try doing solder bridge, hopefully i don't need to cut traces.


EDIT: welp i shorted the solder jumpers and cut the traces...the first chip is still REALLY hot, but at least the board gets detected now. i might try to desolder the first chip with a hot air station since it is apparently still consuming power.


goxed, you cut the traces on a couple of your chips...do those still heat up?

suggested tweaks? Obviously #13 is a poorly performing chip, should i disable it?

[Isokivi]

Sure,

you have [board:chip] on every line and on the board chips are numbered from 40 to 4F beside each chip.

Chips start in the lower left corner, connector facing down, go up, then down, then up, then down again reaching the lower right corner of the board.

I can confirm that this is correct in identifying missing chips, where as the running numbering is not.
