[ANN] US/North American Bitfury sales NEW STOCK ***NOW SHIPPING***

[mb300sd]

If anyone else's bitfury randomly stops mining with the bitfury_init_oldbuf error, I've made a easy hack to get around it:

1. run bfgminer from a shell script in an infinite loop
2. modify driver-bitfury.c, add "exit(1);" on line 121

its a dirty hack, but it works

Question to PCB designers:

I submitted a Bitfury h board for fab and got the following message

Code:

1. It appears that your design has 9-12 mil holes, we require a minimum of 15mil drill with drill+10 pads for vias and drill+15 pads for mounting holes.
2. We found over 5 thousand isntances of 5.8-5.9 mil spacing, we require a minimum of 6mil spacing and no less than 6.

Can someone comment if these changes can be easily done in Eagle?

The only holes I can think of are on the vias, there should be somewhere where you can change the default via size to 15 mil holes with 10 mil pads

No idea how to do it in eagle, i've always used diptrace.

Hey thanks man
Any idea why the via(s) were 9mil to begin with? I mean what gives on changing to 15mil?

What did you send them, Gerber files or the original Eagle files?

V3 image file

this bin file didn't work for me.

don't re upload as i just copied the image from another working card of mine.

Dave still needs to get v3 up for everyone else though that might need it.

Obviously you want to make sure that the new larger vias don't short anything, and that you have clearance between them. They were probably 9 mil because the fab the designer was using could do 9 mil. I'm used to using oshpark and just about everything I design are at their minimums, and even then I have trouble with via spacing for things like tqfp-200s

Dave still needs to get v3 up for everyone else though that might need it.

It ended up working for me when I downloaded the imaging tool he specified.  However, V3 ended up running somewhat slower than the V2 image on my pi for some reason.  The rig went  from 480 gH/s after 12 hours to 455 gH/s after 12 hours.  Although, I did tune two cards down 2.5 gH/s so their regulators would run below 110F)  Regardless, I put a tip in the tip jar taco, thanks.

FYI to any future buyers, in addition to the multimeter mentioned earlier, an IR thermometer will save you a ton of headaches:  It gives you some idea about what you cooling needs actually are.  I aim mine with the laser at the top of the radial capacitor at a 45 degree angle so the observation cone hits the regulator and the coil.  You will also need a 5/64ths Phillips screwdriver or slightly smaller for trimming the potentiometers.  I would recommend this anyway even if you do not plan on overclocking for initial debugging and increasing efficiency later on in the rigs life.

Thanks man! Also is there a quick fix way to change spacing or do i have to manually look at DRC errors and move the routes?

Here's the V3 image, sorry for the delay.  Please *only* download this if you have the new overclocked V3 boards.  It will make previous boards run slower (clock reduced due to higher voltage).

This is not a new, improved version - its just what we shipped already, in case you get a bad SD card or your SD card corrupts.

This new image has a Shutdown button - use it rather than just pulling the plug on the power and your SD cards will do much better!

Cheers,
Dave

Wishing you all the best with your rigs and enjoy the high BTC prices!

Thanks Dave. 

When do you think we might see some new H boards for sale on the website?

thanks for the file. but can you please get back to me about my bad mborad. still haven't gotten any reply back yet.

[BTClobsta]

Productive night of troubleshooting... Thanks to everyone for all their pointers and advice in this thread.

Dayummm, that's sexy. I can get 520 Gh out of one, but I have a couple bad boards on the other and it can only get up to 422 Gh.  

 In the interest of full disclosure, that number is not my Bitfury gear exclusively. Have one rig running near 520 more-or-less stable, and another rig with 3 bad h-cards (2 DOA and 1 with a malfunctioning pot that won't volt above 0.127V and hashes at <2GHs) is stable at near 400. Have an RMA pending for the 3 bad cards after doing extensive testing last night.

 Will be doing more troubleshooting and tuning this weekend when I move the rigs out of their test environments.

did they ever get back to you about your rma? and if so how long did it take?

[Xian01]

 No response yet. Patiently waiting. Can only assumed they are slammed with their own mine and/or waiting for stock... but... yeah. Patiently waiting for a response.

They sent me an extra H board... I've pm'd Dave about how much he wants me to give him to let me keep the one I have that requires lower volts, lol.

For the sake of curiosity, how long did it take before you got a response ?
