[ANN] Bi•Fury | 5 GH/s USB Miner [IN STOCK!] {SALE !}

[Anonymousg64]

Any chances the prices of these will go down, currently with the rate of difficulty increase there is no way it will pay for itself in bitcoins.

10 of these would generate 0.0413BTC/Day at current difficulty.
i would need a price of 0.1BTC per device to break even in a timely and worthwile manner.

adjust you price for difficulty and exchange rate.

> $110.00 per GH/s is not really compelling at this point. Hashfast is a $5.625/GH/s

BiFURY running by itself on a usb 3 hub with a fan

I have also tried the most up to date CGMiner. Have used zigzag and with the bare firmware
It is never seen

USB3 slots and these devices on cgminer are problematic. Try in USB2 slots if you have them available.

Thanks it is working well now useing USB 2 and a powered hub on cgminer Winusb at 5GH/s

thanks

Hello,

I have got several BiFury miners, it looks like it has very little or almost no support at all.
That's why I'd be happy if someone could help me a little bit.

First o fall is there some way how to get it running under Linux? To be more specific Debian 7.2.
When I connect device to system in kernel log I see:
[1704559.597506] usb 2-2.1: new full-speed USB device number 9 using uhci_hcd
[1704559.733273] usb 2-2.1: device descriptor read/64, error -71
[1704559.860650] hub 2-2:1.0: unable to enumerate USB device on port 1

It looks like I need some driver is missing (module).

Few more questions:
Under windows I have running devices with cgminer, but no device is running with promissed 5+gh/s I have about 4.6-4.7gh/s. What can cause this problem?
What is normal running temperature and what is maximum acceptable temperature for this device?
What dose red blinking led mean?

In bgfminer readme is written:

If you want to upgrade the firmware, unplug your device. You will need to
temporarily short a circuit. With the USB connector pointing forward, and the
heatsink down, look to the forward-right; you will see two tiny lights, a set of
2 terminals, and a set of 3 terminals. The ones you need to short are the set of
2. With them shorted, plug the device back into your computer. It will then
pretend to be a mass storage disk drive. If you use Windows, you can play along
and just overwrite the firmware.bin file. If you use Linux, you must use mcopy:
    mcopy -i /dev/disk/by-id/usb-NXP_LPC1XXX_IFLASH_ISP-0:0 firmware.bin \
        ::/firmware.bin
After this is complete, unplug the device again and un-short the 2 terminals.
This completes the upgrade and you can now plug it back in and start mining.

It looks quite clear, but only problem is where I can get mentioned file firmware.bin? And why should I change it?

Maybe there is some way to overclock device, to get higher hash rate?

I'll be happy if someone could help or explain me any of questions written Wink
Thank you!
Cheers,
Lauris

No, this looks more like a broken USB hub or insufficient power...

The shipped firmware for some (most?) of the bi*fury is buggy, and an updated firmware is needed to get them to mine correctly.

Good point, I'll check that. Maybe you know what kind of device is it? tty?

Could you please point me where to look for more info about update? Somehow couldn't find anything usable, perhaps wrong search parameters

Yes, a USB CDC ACM device, so would be /dev/ttyACMn form.

Felipeo said it would be on http://store.bitcoin.org.pl/support a few weeks ago, but I can't seem to find it either

Sorry for delay!
I just add newest firmware and upgrade instruction.

Please check it on store.bitcoin.org.pl/support

And for clearance, we have a middle firmware since we start selling and we are testing our equipment before shipping, especially to catch all kind of buggy devices

That's good news.
Is there a way to check what version currently is installed on device? Of course I can always compare firmware.bin files

Still I'm curios about red flashing LED what dose that mean? Asking because I have several devices and only one have flashing that LED, on other hand, all devices have accepted shares as reported by cgminer. As the color of LED is red I start to worry a bit, is it some error, warning or what

[cscape]

In the latest firmware, the red LED flashes every time the card has found a share that meets the difficulty.

Everyone else experienced performance issues after upgrade?
I had about 4.8gh/s before, now I have bellow 2gh/s

Damn, just saw it. Same problem here :-(
So beside the "old problems" (not working properly in combination with other miners) I now also have a reduced hashrate. Bad deal...
Can someone upload the old firmware, please? Unfortunately I did not save mine...

Unfortunately I don't have option to upload files here, probably I'm too "green" here.
But if You PM me I can send you by e-mail. I have saved mine.

I tried downloading the firmware from the support site, and I can reproduce the slow miner problem.

I've uploaded a fix here: http://c-scape.nl/bi-fury/firmware.bin

(the problem is that the new firmware sets the Bitfury ASIC clock speed at a very low level, and waits for the miner to adjust it. I've changed that to have it initialize at the old level, after which the miner can adjust it if necessary).

I recommend only people with problems try the new firmware, until it is confirmed that it works. If you don't have a problem right now, just wait..

[FlensGold]

I just added the BI*Fury with the (new) official firmware to my minepeon setup:


Running bfgminer using "sudo" at least it shows up as "BIF" but unfortunately only returns 100% HW Errors.
I appreciate any suggestions to solve this problem.
Kind regards

[Humanxlemming]

$400+ for 5gh? it would be cheaper to buy block erupters

It works better for me, but now hashrate is changing from 3gh/s to 5.2gh/s (once was 5.6) by average effective hashrate is 4.7gh/s one of devices started to generate duplicate shares. What can cause duplicate share issue?

Good news is that at least at first impression it works little bit cooler.
