Blue Fury Support Thread.

The heatsink on the BlueFury is a bit feeble.  I replaced mine with the heatsink off an old dead Matrox G450, stuck on with 3M double sided thermal tape.  Now runs without fan cooling @ 2.7GH.

Since mine all run at low temperatures (well cooled) but only @ ~2.1GH, how did you get yours to run @ 2.7 ?

most probably a pencil mod. it involves a pencil and rubbing it along the side of a resistor. if you dig back a few pages there should be a detailed tut

Windows 7 x64 and getting this problem any ideas how to solve this.

You need to disable driver signing Windows security feature.
In elevated (as administrator) command prompt type commands:

Code:

bcdedit -set TESTSIGNING ON

to return enforcement back:

Code:

bcdedit -set TESTSIGNING OFF

HTH!

HI @all Windows 8 Users .. those command line didnt work for me here .. so i decided to give you th elink to the howto that worked for me.

http://www.deskmodder.de/wiki/index.php/Digital_unsignierte_Treiber_installieren_-_Windows_8

it is in german sorry ..

After this my nanofurys and bluefurys work all on the same pc and the pi is obsolete as long as the nano's didnt work with the pi ..

I received my BlueFuries today, before that, in my absence, they were hosted by ssinc. I am a bit stumped as to how to make them work.

My system is Win 7 64 bit.

Downloaded driver from the second post of this thread.

Plugged in one BF -> orange light and unidentified "Other device" in Device Manager

Updated the driver from the Device manager -> it is now identified as "Bitfury BF1 USB Miner (COM4)" and the LED shines red.

Driver version is "10.0.0.0", date "01.07.2012"

Run bfgminer ver 3.8.1 (latest) with

 -S opencl:noauto -S bigpic:all

and get:

"Do not have user privileges required to open \\.\COM4"

Tried both 32-bit and 64-bit versions of bfgminer with the same result and ultimately "No devices found"

So, the questions are:
- Do I have the latest driver and if not, where do I get it?
- What else do I need to make bfgminer recognise BF1s?

[FalconFly]

Not having user privileges sounds like you may have to launch bfgminer as Administrator (just guessing) ?

I don't get the same problem with BEs.

EDIT: a bit of the log:

 [2013-12-12 21:35:24] Started bfgminer 3.8.1
 [2013-12-12 21:35:25] Failed to open Device Parameters registry key in lowl-vcom.c _vcom_devinfo_scan_windows__hubport():436: The system cannot find the
file specified.
 [2013-12-12 21:35:25] Do not have user privileges required to open \\.\COM4
 [2013-12-12 21:35:25] Do not have user privileges required to open \\.\COM4
 [2013-12-12 21:35:25] No devices detected!

EDIT 2: Might be a Win 7 issue. I've now gone through the same steps on a Vista 64-bit machine, and there 32-bit version of bfgminer 3.8.1 starts hashing on BPM0

EDIT 3: Definitely something off with this particular machine. It got detected fine on another Win7 (on the second try, after pressing reset on each device).

Hm, I can only tell you how I got mine to work (WinXP though) :

- plug one of them in USB Hub
- wait for Windows to install the (wrong) default Driver
- I used Zadig WinUSB Utility to conviniently install proper WinUSB driver
- after plugging out and back in, cgminer 3.8.4 recognized the device immediately

I did have some troubles IMHO with the USB power supply though, plugging in several BFs in too quick succession (one after the other) caused several errors and some or all devices were not properly recognized.
Also, after plugging in one with 3 already installed & running, it caused one or more others to drop offline or go into Zombie status.

Solved it by having them all installed already, then powering on the USB Hub (while cgminer running and waiting for devices to load with work).
So in short, in case of problems it seems best to get one single USB ASIC up & working alone first, only after that try it with all USB devices plugged.

(at least that worked for me)

Hi Beastlymac
Please can you tell me the grade of thermal tape you used for the Bluefury heatsink mounting?

Hi Beastlymac

I will try and find out tomorrow for you.

[Tawnos]

Now that I have posting ability here, I can link to this. I created a signed driver for the bitfury device. If you're on Windows 8 and don't want to have to disable driver signing enforcement every boot, you may use it. Instructions are here: https://bitcointalk.org/index.php?topic=367981.msg3930046#msg3930046

Sure. Although i would recommend if someone has a faulty unit that is unmodified for them to contact us about getting a replacement. Once units have been modded we can't offer replacements.

Hi BeastlyMac

I sent a faulty unit to Julz which he received on 22/Nov and I haven't heard anything back, were these being replaced or credited? This was not modified at all (not even Pencil Mod). Thanks.

Bump, Update please Julz or Beastly? Thanks.

Hi Beastlymac

0.95 thermal conductivity. -30 degrees to 120 degrees.

Hi Beastlymac
Thanks for the info. I have a cooling fan to mount on one of these fury's (found one with the same hole pitch, £1.64 including delivery) then I just need some mounting  tape.
Overclocking for Christmas. (more fun than a turkey)

Will do.  I need to go steady with the overclocking, unless Santa brings me a thermal camera.

I had 2 reds and a blue running great on Mac OS with cgminer 3.8.4

Now I get this error for all 3...

"failed to initialise (incorrect device?)"

Any ideas what the issue might be?   

[Beastlymac]

Seems like a permissions error try starting with sudo. Or restarting your computer. Or even re installing cgminer. I found those three generally fix the problem.

Thanks for your help.  Unfortunately, I've tried all 3 of your suggestions but I'm still getting the same errors.

Have you tried Bitminter and Bfgminer?
