Thanks jedi, I've been waiting for my account over there to be approved for several days now.  That's what was making me wonder if he was still away.

I'll take care of it right now for you!

Hi
Can not open drillbit forum and would like to know what should been done with the dead board
Tried everything to get it back alive but it does not react at all

[forevernoob]

What do you mean "can not open drillbit forum"?
The site is up from here at least...

[bronan]

Never mind the forum opened just now

Just made a profit calculation based with current difficulty 1,418,481,395.00
The 7 boards do around 110 Gh, they pull including 4 cooling fans and the usb hub and htpc (3 core amd) 270 watts
Electra price in dollars 0.37 Kw/h
Resulting in :

Coins per 24h at these conditions    0.0390 BTC
Power cost per 24h    2.40 USD
Revenue per day    31.12 USD
Less power costs    28.72 USD
System efficiency    407.41 MH/s/W

Hardware break even    93 days
Net profit first time frame    -44.75 USD

but sadly only 1 day left till next diff 1.8 billion +

sorry if this has been asked i have been away for a while

i got the boards from repairs and they are hashing away thanks

do i need to update to the latest firmware or do i have it already updated?

i am also getting timing out on asic bla bla bla

and lot of HW errors

i have a fan sitting on top of the 8 boards

Thanks

You can check with your repairer, or simply try to update the firmware to the latest one of one of your boards, and see what is reported.
Cgminer 3.10.0 (the official release) now supports these boards.  I have been using it for the last 2 days (for the Thumb too).
Regarding HW errors - you may want to try different settings and find the optimum one regarding hash rate and errors.  I'm getting about 3.1% HW errors at a hash rate of 22.5 GH/sec (avg), with a temp of 29-31C (and plenty of good cooling, NOT just a single fan above the boards).

Good luck

Here's some quick documentation I wrote up from the cgminer driver code, in preparation of writing the BFGMiner driver:

Code:

L	Identify*
I	Get info
	0x10 bytes response:
		uint8: protocol version
			protocol version 2 has an implicit external clock if chip count is 1
		char[8]: product name
			if "DRILLBIT", fill in "Thumb" or "Eight" appropriately
		uint32le: serial number
		uint8: chip count
		uint16le: capability bitmask
			0x0001  Temperature sensor
			0x0002  External clock
R	Reset*
C	Configure
	Request followed by 6 bytes:
		1 byte: core voltage config
			0x01  850mV
		uint8: clock level
		uint8: "clock_div2"
		uint8: use external clock? 0 or 1
		uint16le: external clock frequency
	1 byte response: 'C'
T	Get temperature
	2 byte response:
		uint16le: Temperature in decidegrees celcius
E	Get completed work
	Response:
		uint32le: number of works finished (max 1024)
		For each work, 68 bytes:
			uint16le: chip id
			uint8: number of nonces found (max 16)
			uint8: non-zero if chip idle, otherwise 0 if busy
			uint32le[16]: nonces
W	Send work to chip
	Request followed by 46 bytes:
		uint16le: chip id
		uint256le: midstate
		uint8[12]: data tail
	1 byte response: 'W'

I have 4 drillbits and a miniplane.  One drillbit does not power up.  They have never been overclocked, always fan-cooled.  All for sale as-is to the best offer, or 3 BTC buy-it now.  PM me to confirm a deal.

You might sell them faster if you post on the drill bit forum and post your continent.

I doubt it, this thread is more active than the drillbit forum.

I see some drillbit boards on eBay atm. (search on bitfury to find them)

[techman05]

I think at those prices I'm waiting to see if Barntech turns on his AC and wakes up  with the avalon chips (Last thing I heard Australia was under a heat wave) .

I so thought we'd be swimming in chips this month by now.

This is what Barntech posted on the Drillbit forums back on the 6th. he doesn't seem to have surfaced since:

As for the Avalon hashrates, the chips do about 1.6 GH/s so the 16 chip board will come in around 25 GH/s. Still working on the pricing. I'll get that up soon. We'll probably just do one run of these because the chips aren't all that exciting to be honest.

Also, its looking like more bitfurys will be available soon so we might be looking at doing some more of those. This time probably the turbo design which can squeeze some more juice out of the chips.

Thanks for your great work, it will be fantastic to have bfgminer support for these Drillbit miners

Cheers

Is bfgminer live with Drillbit support yet?

Not yet, hopefully soon.... TK said that he delivered a board to Luke-jr, and based on the recent post that you quote, he's working on it.
