Topic: Blue Fury Support Thread. - page 23. (Read 89538 times)
PS / HELP: One definate "how-to" run multiple block erupters and multiple blue furies on one raspberry pi featuring minepeon would be greatly appreciated. Does bfgminer listen to "bitfury" or "bigpic" when it comes to detecting and running the BFs? Thanks in advance, I am getting more and more desperate here
I wonder if I have a bad unit. I've read through this thread, and I've never seen anything better than 1.2GH/s. Different setups, always powered. Screen shot below shows bfgminer 3.5.1, but I've tried cgminer 3.7.2 and bfgminer 3.2.0. Linux and windows.
If this is a bad unit, can I send it in for a replacement/repair?

I am having the same problem and I have also tried Linux, Windows, cgminer and bfgminer. Have you made any progress?
Yes, I contacted my group buy leader. Sending the unit back to him for replacement.
Under BFGMiner the first figure is 5 sec average, second figure is all time average, third figure is average for pool (corrected for rejected).
How long were you connected? It could take an hour or more to settle.
That was running for a couple of hours. I will try again and leave it overnight.
To follow up on my earlier report, raspberry pi plus dlink dhub 7 that hosts the blue furry and links to two cheap chinese hubs with 9 erupters each running cgminer with NO special command lines gives:
Any decision on a new batch or should I be looking at the red fury group for more?

Does anyone know if pencil modding (or replacing R15) will result in higher current draw? Could it possibly push the device over 500 mA?
Just pencil-modded mine to about 0.85 MOhm getting 2.99 Ghps each.
Both sit in front of a big 120mm fan.
Is this okay or should I go lower in terms of Ghps?

As long as you got that fan there and it isn't hot to the touch you are probably fine.
I'm not familiar with pencil modding, will this make these run a lot hotter to where a fan is needed. My Red Furies are running super cool to the touch.

of the r15 resistor itself? I did not take a before/after
Just take a #2 pencil and make 2-3 lines across the side of the r15. you should see atleast 10-15% gain

thanks, i haven't done a pencil mod since the ATI radeon 9700 day's LOL (2003) i think. now should i draw the lines on top of the resistor or just the sides? both sides? and i wonder if this will work on BE for R1 chip Thanks
the graphite doesn't seem to stick to the top. just along the side
I wouldn't overdo it. Once you hit the 2.7GH/s range I would stop

pencil mod definatly worth the few seconds it takes
And now 10 mins @ .92k
many errors...
do you have a picture of the bf R15 before and after pencil mod?

Also bitminter reports higher speeds
Jeez, your Furies are performing well compared to mine, are they standard or did you mod them in any way?
pencil modded
going to run on BFGminer for a little now
a little more pencil with a fan on them now..
Talk about a PAIN IN THE ASS!
Finally able to get 5 going at once

Anyone know how to clear my com ports out. Every time I switch from Zadig to Alpha driver it keeps ahold of the old com port and uses a new one.
They don't show up in the Device manager not even when I unhide
You could try the device manager cleanup instructions in https://bitcointalksearch.org/topic/windows-many-usb-hubs-and-besfuries-clean-up-in-your-devices-manager-300638They don't show up in the Device manager not even when I unhide
It helped me with multiple Com port settings for BE's.
Cheers
Thank you worked like a charm!
I also did pencil mod and after a bit of playing got some good results and had to erase my lines and start over cause went bit too far :-)
I had no idea what a pencil mod was so googled it for other like me : http://www.techarp.com/showarticle.aspx?artno=106&pgno=6
It does help but be careful how much you push it. If you don't have a voltmeter that can measure resistance get one they aren't that expensive then reference frontlinefodder's posts about resistance before/after.
I do wonder with some upgraded cooling just how far I could push this lil thing :-) :-/ >:-)
