What would be a fair asking price for 9 PCI Hash cards and M board?

1.75 btc

I'd offer 2.25 BTC for that, if I was looking to buy more hardware.

On Mar 7, I received a 1TH Desk for this order. It was shipped Mar 3, but was delayed 2 days because of import paperwork.

Nice to hear that you received the miner!
Actually funny... I have also order number #220X, paid same day 13 Oct / BTC... so maybe delivery is nearby also here...

They emailed me the tracking number the morning of Mar 3. If you didn't get that, you should contact them.

Then it does seem that most or all of the failed bitcoin withdrawals occurred around Feb 10-12. There are at least 7 people complaining about this on CampBX's facebook page, and CampBX acknowledged at least ~20.

I just did a small deposit and withdraw as a test, and everything went quickly as it should.

They finally broadcast the withdrawal transaction, only 18 days late.

Have bitcoin withdrawals from CampBX been processing quickly (i.e. in minutes) recently or is this an ongoing problem with CampBX?

A friend of mine tried to withdraw ~6.5 BTC from his CampBX account 17 days ago. CampBX apparently never broadcast the transaction to the bitcoin network, since blockchain.info doesn't see even an unconfirmed transaction. He submitted a support ticket the next day, and it has now been 16 days with no response.

Yeah that's clearly Bitmain - aka antminer.

MBP is 3x as expensive as Bitmain, at least at the nominal speeds. 2x as expensive when overclocked. The Bitfury guys are way out of touch with the mining market now.

^what about price adjustments in the MBP store?
lulz

double lulz,

We have 3 pages of cost adjustment questions and we get a reply about where he is going/meeting. With the btc price low now, antminer is better choice by a huge margin. 400 for 35gh +controller or 750 for 180gh standalone machine, tough choice right?
Yes indeed Smiley

Aside: Hmm - so why does my BA fury board do 40.1GH/s paid to the pool?
What's up with the ones made by the guys here?
(or is that something to do with my cgminer driver?)
Yes these are real questions ... I've only had access to a small number of BA fury boards and basically no access at all to the boards listed here.
So I've no idea if my driver needs more work to support a lot of boards (yeah there really isn't much CPU power in an RPi) or if something else is going on.
I guess I need to spend some time on a large BA fury setup and work out what's going on with these crappy performance figures reported for the hardware here.
Then once I'm sure cgminer performs well with lots of boards, then the question here will be why on earth the boards here are rated so low.

What voltage do the BA boards run at? My best MBP boards can get just over 40GH when the weather's cool. But the main bottleneck seems to be the voltage regulator. Most of my boards are overvolted to around 0.86v, and the speeds are set just below where the regulator would cut out due to overcurrent/temp. At 0.86v, they could usually be clocked higher before getting too many errors, if it weren't for the current limit. I can determine that by turning off a couple chips and clocking higher until the errors start. Do the BA boards have a higher current limit than 30A?

^really hope it involves actual competitive pricing. For a more-stable, stackable/enclosed bitfury I would gladly add it to my growing collection of antminers - but only if they can get their shit together and
1) price in BTC - for the love of god.
2) price no higher then 10% above the antminer - those things are simple, elegant tanks that dont wobble, dont blow sd cards, and only require the single fan that they ship with. The only upside to the bitfury is saving ~1w/GH

And saving 1W/GH only saves $0.88/GH per year at $0.10/kwh. Bitfury 55nm will be obsoleted by even more efficient tech within a year anyway, so it's not worth the huge premium Punin seems to think it is.

It's unfortunate that they didn't spend the little bit extra to gold plate the contacts on the cards like most PC expansion cards are. I think that would have prevented alot of problems.

Well, I am at a loss of whats going on with my setup.
Got replacement card and the rig been mining about 12 hours.
Now I get notification of hashrate drop. I login to see a few of the cards at Zero.
Reboot Pi and only first 3 cards are hashing.
My room is at a constant 60F with fans blowing over the cards.
Huh

Set all chip speeds to something slow like 50 with autotune off, and restart chainmminer. If the problem persists, reseat the cards.

For comparison, Bitfury chips use a similar package, and I figure they dissipate about 2.5W in my overvolted rigs with just high-flow fans and no heatsinks. Bitfury chips use thermal pads to dissipate most of the heat through the PCB.

ok, now it's happening to me; again.

absolutely no hashing with one of my 14 card rigs.  changed out SD cards and raspi.  can login into admin page but no hashing.  took rig apart and checked for any burnt boards (none) and blew out M board connector in case of excess oxidation (none apparent).

what were all the suggestions given for this frequent problem?


I've said it many times before, so I'll let you scroll up for details, but you need to check the output of chainminer and the proxies.

i only have 2 screens:

Code:
pi@192-168-7-243:~$ sudo screen -r
There are several suitable screens on:
2069..192-168-7-243 (28/01/14 23:39:27) (Detached)
2063..192-168-7-243 (28/01/14 23:39:27) (Detached)

here's some of the output of 2069:

Hmm, that hasn't happened to me yet, so I don't know what's the problem. It seems the chips are getting work but are returning tons of bad nonces and other errors. Is this a multi-bank M-board? My first thought is a bad connection, but it's too coincidental for all banks to do that at once. Maybe one of the voltage regulators on the M-board went bad? One should be ~1.8v and the other ~5v. The 5v just powers the rPi, so must be ok. But I can imagine bad 1.8v for chip comm causing weird results like this.
