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

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

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..

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.

Duplicate shares are fairly normal in the beginning, when the chips aren't initialized yet, but they should stop after a minute or so. Are you only getting them on one device and not the other ? If so, does it also happen when you only plug in one ?

What temperature are the devices running at ? I also added a temperature switch at 90 deg C. Above that temp, the bitfury chips are turned off.

I have done some tests.
It looks like duplicate shares is generated when running without fan and temperature is getting close to 90C. Perhaps it is switching off and on again?
With old firmware (original one) without fan it gets to about 120-125C (quite hot) and stabilizes.
I have checked once more with fan (I only have quite a powerful one) it works at about 40-45C.

Don't know is it OK for this device to run at about 125C or not, have seen devices running on much higher temp, but that isn't asic or hashing related stuff.
I have got answer from support:

Acceptable temp are high but we advise little usb fan for little cooling and keep them lest than 50 C degree.
But what dose "high" mean? Wink

Better use a small fan and keep
temperatures well  below 125 oC:)

I would think 120-125 deg C is very hot, that's why I set the upper limit at 90.

However, if you'd rather push the envelope a bit, and run the device at 125 deg C, I have uploaded a modified version at http://c-scape.nl/bi-fury/firmware_125.bin

Note that the voltage regulator has a maximum junction temperature of 150 deg C, and it's generating quite a bit of heat itself, so 125 degrees probably causes quite a bit of premature aging in the device. Of course, with the difficulty increasing rapidly, life span may not be very high on your priority list Smiley

Edit: I agree with intron. A fan is highly recommended...

Correct. As soon as temperature goes < 90, the chips are enabled, and > 90 they are disabled. So if you keep it around 90C, it will keep switching on/off.

Tanks for explanation, finally got some data, yes, if voltage regulator temp is 150C max, then 125 is too close indeed. If it is not hard for you could you please make for me few more firmwares? For example with 100C and 110C limit?

My problem currently is that my ordered USB hub is somewhere don't know where in catacombs Smiley of postal services. But If I connect device to notebooks USB port it is with heat sink down so it is very hard to cool it somehow, if I set up some fan, it is cooling circuit not heatsink which is ineffective. Then I can get down temp to 90-100C.
When I'll get hub then I have everything prepared for normal cooling, at least I hope so.
For tests (when I got 45C) I have used powerful HDD cooler but I can't use it daily as it has HDD to cool Smiley

Do you have idea why hash rate is fluctuating in so huge range?

Thanks Wink

Added 100 and 110 degree limit versions.

http://c-scape.nl/bi-fury/firmware_100.bin
http://c-scape.nl/bi-fury/firmware_110.bin

If the hash rate is based on the number of shares reported by the device,  big swings are common because sometimes the device is lucky in finding a couple of shares close together, and sometimes it doesn't find anything for a longer period. Because the firmware supports difficulty > 1 shares, the swings can be more pronounced. As long as the long term average is good, I wouldn't worry about it.

Hi,

I've tried Win7 (64 bits) and Ubuntu server 13.10, both with cgminer 3.8.4 and USB2 and USB3 ports, but the BiFury wont start mining. I even tried several pools. Also tried the different firmwares posted here the last couple of days, but no luck. Does anybody know what I'm doing wrong here?

I've made an overview of all the different firmware versions, and also included the upgrade manual and the protocol specification that is used between the bi-fury device and the miner software.

Hey cscape

I'm really pleased to see someone on the hardware end put this much effort into the protocol and communication with the software layer, thanks.

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

Go try to get even one block erupter for less than ~60 $ here in Germany :p
Some of these Block Erupters hit or exceeded 100 $ and were actually selling off simply because there are so few offers...

So while it may look like insanity (maybe is), it seems in most of Europe these 429$ Devices should sell off better than happy hour drinks, reseller prices for older/used ~2.2 GH/s Blue Fury easily (!) reach 500+ $ over here.
Given the non-availability or mad cow disease prices of other (faster) ASICs around here, 429$ turns out to be a very good deal in these crazy times...
(all the "sexy" xxxGH/s or TH/s deals are only pre-order which IMHO scares most "want to try this now" buyers off and not everyone wants or can afford to go all-in with a xxxxx$ investment at an unknown/projected date @ unknown/projected difficulty)

I had an order that just shipped... will it already include the latest firmware (the 90C one) or will I have to update the firmware when I get it?

I would think 120-125 deg C is very hot, that's why I set the upper limit at 90.

However, if you'd rather push the envelope a bit, and run the device at 125 deg C, I have uploaded a modified version at http://c-scape.nl/bi-fury/firmware_125.bin

Note that the voltage regulator has a maximum junction temperature of 150 deg C, and it's generating quite a bit of heat itself, so 125 degrees probably causes quite a bit of premature aging in the device. Of course, with the difficulty increasing rapidly, life span may not be very high on your priority list Smiley

Edit: I agree with intron. A fan is highly recommended...

Hello, maybe someone is interested in my results so I'll write here.
I have done some further testing with several setups. Yes indeed without fan it is getting to over 100C of course depends of position of device (best position without fan is vertical - usb connector up or down as that way is better air flow trough heatsink), room temp and of course many more less important parameters.
With small fan positioned to heat sink it is easily to get temp down to 50-60C, as for me to get temp below 50C it requires bit more effective fan.
If fan is positioned over miner and it is pluged in notebooks USB port - heatsink down - then it requires powerful fan to get temp below 80-90C, but it is not comfortable anyway because typically you have to rise notebook from desk a little bit, otherwise BiFury won't fit.

Now I'm thinking about passive cooling, as maximum possible power is 0.9x5=4.5w it shouldn't be hard to cool it with larger heat sink - passive cooler. Unfortunately I couldn't find any suitable heatsink in my warehouse. Maybe someone have some larger heatsink, I suppose CPU cooler will be good enough, even without fan switched on. Perhaps for tests it would be enough to firmly put together BiFury's heat sink and larger one. I don't recommend to remove original heat sink from BiFury because it may require thermal paste to get it back correctly - it is too expensive device for such experiments Smiley Then try to run it for 15 min monitoring temp. If it goes over 85-90C then test has failed. In any case please let me know results.
I'll try to seek for one too Smiley
It would be much more power effective, because as I have found USB fans take about .5A (max USB2.0) so it is ~2.5W more than half of miners consumption. And much silent of course.
