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

Cool, thanks for the tip. I shall give it a go.

Here is a quote from kano:

The BaB driver with 7 boards uses less than 10% CPU on RPI Arch - and for my 7 BA BaB boards, mines at over 270GH/s
It seems to be limited to 2 boards per SPI channel. More tends to get all sorts of errors.
Will look into resolving that ... one day.

Kind of a bummer Most of my rigs have more than 2 boards per SPI channel so :\ yeah..

After a few minutes of running with the bab-options set on my v1.2 rigs it still seems that performance is not consistently equivalent to that of chainminer. That may have something to do with the quote from kano above.

Another thing is I'm not sure if cgminer turns off dead or "zombie" chips like I would when manually editing the chainminer best.cnf file. By zombie chips I mean those that no matter what always hash at a pitifully low hashrate (0.05 to 0.10).

It does shut them down. Check the driver for BAB_BAD_DEAD. This is set to BAB_BAD_MIN * 2 by default. I have cgminer running on a full rig.

The display tells you exactly what's going on with your rig:

0: BaB 0      : 4.16.256 B:034 D:000

BaB 0 4(banks)16(cards)256(chips)34(bad_min)0(disabled)

Here's a very naughty rig:

0: BaB 0       : 4.13.200 B:008 D:025

Cgminer doesn't seem to like the cards set to .85v. The same cards freak out bfgminer.

You can also decrease the time necessary for testing by changing the history setting to something like 120(s) from the default 300(s).

All my v1.2 h-cards are overclocked so maybe cgminer does not like that. The v2.3 is not overclocked by me but it comes out of the box pretty much pushed to the limits (ie the adjustable voltage pot is aggressively tuned already). I dunno, I will wait until the next release of cgminer and see if kano/ckolivas make any improvements. I said it before and I will say it again, I wish cgminer/bfgminer had a chip table that allowed me to manually set which chips I want to be completely turned off or tuned down from the start.

bfgminer already support table with per chip start value.

Here is part of my bfgminer config file that I use on my system where I have about 14 bad chips and I want them to start very low (at 32) but everything else to start at 56. If you want you can set start value for every single chip (like on chainminer).

Code:

"scan-serial" : [ "bfsb:auto" ],
"set-device" : [
        "bfsb:osc6_bits=56",
        "bfsb0av:osc6_bits=32",
        "bfsb0be:osc6_bits=32",
        "bfsb0bi:osc6_bits=32",
        "bfsb0cj:osc6_bits=32",
        "bfsb1ar:osc6_bits=32",
        "bfsb1aw:osc6_bits=32",
        "bfsb1bn:osc6_bits=32",
        "bfsb2ag:osc6_bits=32",
        "bfsb2av:osc6_bits=32",
        "bfsb2ay:osc6_bits=32",
        "bfsb2ch:osc6_bits=32",
        "bfsb3ad:osc6_bits=32",
        "bfsb3bn:osc6_bits=32",
        "bfsb3cb:osc6_bits=32"
]

        "bfsb3cb:osc6_bits=32"
]

How do you identify the chips? I'm assuming the number after "bfsb" is the bank number but the rest of the characters are? Is there some logic to it.

Yes your are right, the number after bfsb is the bank number (0 to 3) the next 2 letters identify the chip in the bank (64 chips per bank - first chip is "aa" follow by "ab", "ac" ... then "az", "ba" ... and so on until "cl").

posted an RMA request for 3 h-cards. just a heads up MBP 

[Lloydimiller4]

I've got 8 Bitfury ASIC chips that I don't want/need. I will send them to anyone who wants them if they cover shipping costs. PM me.

Are they Rev2?

[Lloydimiller4]

No, they are Rev1

Hi guys, just wondering, how 55nm bitfury ASICs still going good when KNC is releasing 20nm ASICs?

If I can afford more space then I should choose bit fury over KNC?

The only outlet you can presently get bitfury hardware through is the EU site

Bitfurystrikesback.com

With the way KnC has been recently, I'd personally go bitfury

There are many other more desirable options these days.  Just have a look at the rest of the Hardware forum.  The current Bitfury products just aren't competitive price-wise.  Perhaps the next generation Bitfury products will be more reasonably priced.

And for god's sake, don't preorder from anyone if the product ships more than two weeks from the time of order.  There is no need to gamble like that anymore.

Ugh. Nerd jokes.

Just when this forum seems to nerdy to be real, someone has to go and up the nerd-quotient.

You mean $105 per board, right? Assuming each card gets 31 gh that's a total of 279 gh which currently earns $307 /month.
