UPDATE

MAJOR PRICE CUT DUE TO BTC RISE:

1.5 BTC /board
11.2 BTC / 8 board tower

Make your order now!

Keep deleting my posts. Doesn't change the fact these are still overpriced

edit: I offer 1.1 per board for 8 boards, shipping included. So 8.8 BTC total, offer valid till sunday.

1,99 BTC for 1 board

Will you replace my 1 broken board if I order more? I would've order more if that board didn't broke only 3 days after I receive it

We would like to inform you that Bitburner Fury boards are available again on www.asic-hardware.com

Boards are in stock and orders placed will ship on Monday November 18th 2013. We are also offering additional accessories (PSU, Raspberry Pi's) at economical prices.

I actually managed to add epoxy to my board (before I sold it) without gluing in the cable.

I left the cable in when applying epoxy (otherwise there was a risk that if the epoxy got into the connector the cable wouldn't be able to go back in), but I put tiny little bits of sellotape on the small openings in the sides and back of the connector (and where they wouldn't stay on, dipped the edges of the bits of sellotape in a drop of superglue so they would stay).

Then I applied epoxy on top of the sellotape (with the USB cable still in the connector). After a couple of minutes (once the epoxy was mostly dry to the touch) I *very carefully* unplugged the connector, holding my thumb on the connector so that it wouldn't be pulled off the board as I pulled out the cable. I then plugged the cable back in, with my thumb still on the connector. I then allowed the epoxy to dry fully overnight.

From then on, I was able to (still carefully!) unplug the cable without any issue. Just thought I'd post it in case it helps anyone.

As much as I love these boards they are a pain to keep running.

First, after some time they began to crash my raspberry pi. Like caused the pi to completely freeze up requiring it to be power cycled. I tried two different raspberry pis, two different SD cards, two different versions of raspbian, two different USB hubs and using both wifi and wired ethernet. The only thing I could think was the power adaptor was not strong enough. I bought a heftier one but I haven't gotten a chance to try it yet. For now, I gave up and switched to using a Linux PC.

Having 8 boards chained together was really unstable (frequent USB write errors that would crash the whole setup), so I went with 2 sets of 4. Sometimes that would run for days without problem, but then if I ever had to restart it, I would have to spend hours, if not days restarting it repeatedly when it crashed or the hash rate permanently dropped (seems like one board would occasionally go dead?). The weird thing was if I got it running for a few hours, it would run for days or more without any problems. In other words if things were to go wrong, they would within the first hour or so, usually within the first 10 minutes. Very strange.

Presently, I have a 7 port USB hub with 6 USB cables going to 6 of the boards, and the other 2 boards chained. Those two boards had their mini-usb plugs broken off. I have a 9th board with a broken usb connector too but that board is completely dead (no lights go on at all) and I have no idea why. It seemed to frequently overheat and crash a lot until one day it just died. I have a feeling static might have killed that one. It seems much more stable using usb rather than the canbus cable. I've upgraded the firmware to all the boards I could (that still have usb connectors).

Also, I epoxied the remaining connectors so that they will never ever come off, but that also means they have usb cables permanently glued into them.

Anyways, I have 8 boards running at 1325 mv (probably could do 1375 and be ok) and 115200:128:10:45:282 for the options settings. They are drawing about 800 watts and get an average of 381 GH/s.

No, that's right, I have 8 boards and it draws exactly 800 watts.

That's actually a good idea zefir, i'll even go as low as test one by one if needed.

I did not watch the red LED frequency with mine stacks, but what prevented them from reaching 400GHps turned out to be insufficient power. With 850W PSUs I was not able to reach more than 360 (and also had USB errors, btw.), now with a 1200W PSU everything works smooth and each board is at 50GHps on average (1080mV, 275MHz). At wall I measure around 750W draw, but there might be spikes that a PSU operated at its edge can't handle.

What you can try to double check is to operate only 4 boards at a time and check they reach 200GHps (terminate CAN bus correctly + unplug ribbon cable from inactive ones). If so, you need a stronger PSU.

Also, I instructed you to use an older version from cgminer for best results, which is not true anymore. Current master HEAD works fine with the latest BBF firmware.

Hello all

I have a stack of 8 boards. They are terminated and working as expected. Almoust.
I'm only getting 350Gh/s from them and expected 400.

However, i noticed that the board where the USB is connected, the red led blinks much less, and is way colder than the others. Changing the USB to other board makes that other board slow down.

Does anyone have a tip?

Your multimeter will have a few Ohms settings.
Choose one and hold the two leads together.
The display should show 0 ohm.
Now hold the two leads to each end of the fuse, the display should show 0 again.
If it doesn't, the fuse is blown and has to be replaced.

It's only been 3 days of hashing and my board I won from your auction for 3.3 BTC went dead. I received it at 7th Nov (check the fedex tracking) and it went dead at 10th Nov (check my PM date to you) but you never reply to my PM even just to say "sorry dude, you're on your own" so I know I must seek my own solution.

One of the 4 boards I have has not been hashing for weeks because it is faulty, maxing out at 12Gh/s. I have been waiting for a response to several emails since mlate October and then you delete my posts today in this thread when I have a legitimate issue to discuss. I would rather you send me a replacement board as compensation for the lost time and hashing power, while I ship back the faulty one immediately for you to examine that its certainly faulty. The long turnaround time to ship US<->Belgium and the fact that you will attempt to 'fix' it with no estimate as to how long that will take, is somewhat disconcerting. I am just saying it how it is. At this point I would prefer a partial refund because it saves us both headaches. I can supply all the images/screenshots/videos to prove that it is underperforming below your 40Gh/s advertised minimum.

We like to help our customers as good and as fast as possible. Every board sold is tested extensively.

If you have a problem with a board, pls contact us immediatly.

I hope you understand we cannot be held responsible if something happens to a board after hashing it for weeks.

The board works PERFECT.

49GH/s average at 48-50ºC at 278MHz (settings 1300mv = ~1025mv I remember)

I'm testing with another options, but this is the best.

I have it with a Rpi with Raspbian and cgminer.

ByE!

The boards are great when they work, weeks without any hiccup. I even consider purchase more after this but I think I'm gonna fill up my Bitfury Starter Kit instead

Yes, both power connectors is not working. With watt meter it show only psu power draw about 6 watt.

How do I check if the fuse is blown with multimeter? I got 0 knowledge about this kind of stuff but I got multimeter for my Bitfury Oct Kit.

Have you tried all power connectors ?
Are you sure your power supply is ok ?
Check the fuse, it's probably on the same position as the Bitburner boards: http://www.burninmining.com/news/ (first picture)

No reply on my dead board PM so I'm gonna take my dead board to local laptop repair to see if they can fix it. Hope this is the right course of action.

Nothing burned on the dead board but it drain no power at all. Anyone have any idea what's wrong with the board?
