2501  Bitcoin / Hardware / Re: [Antminer S1 Sales open] Price changes daily, now 0.999 BTC for 180GH/s on: March 10, 2014, 11:40:52 PM
does anyone know how much bandwidth 1 dual blade Ant needs?

not much. looking at my router for banwidth monitoring:
LAN: 22kbps IN / 25kbps OUT
WAN: 10/12
Wifi: 20/22

This is between 6 antminers, a bitfury, my laptop, and a 2MH/s scrypt rig.   Its safe to say that the bandwidth usage is next-to-nothing

for renting a co-location, you need the slowest option they have. you could probably get away with dial-up. (This is the reason i opted away from the co-location route; datacenters are designed for FAST internet and moderate power demand. Bitcoin miners only need a basic internet connection but HIGH power demand)


So lets say you did colocate. How would you access the miners remotely? Would that be possible to setup?

I see there being two ways:
1) via IP access to the unit. this could be difficult or unallowed by the data center's firewalls and certainly require having explicit permissions set for the ip range of your miners
2) install a small pc that you can connect to remotely via teamviewer or similar, and use that to access the local miner IP addresses

The second option is probably the most common I would imagine
2502  Bitcoin / Hardware / Re: HashFast announces specs for new ASIC: up to 800GH/s on: March 10, 2014, 11:37:14 PM
there is a lot of saying 'cointerra didnt meet 500GH' while saying 'we can achieve 800GH!'

Cointerr has units in customers hands - lots of units. hashfast has a massive line of customers still waiting on the MPP (which was a protection against late delivery - ohh the irony)

They then go on to flail wildly about having a 2.1TH miner using 3 chips. That means that the miraculous 800GH chips are actually running at about 700GH, or almost 15% under spec. I could shove 20 antminers into a server cabinet and call it a 4TH machine - would that make it a better product then hashfast's pathetic 2TH?



..the answer is yes. I would have those 20 antminers in a cabinet in less than a week from today. Hashfast might ship something in a month or two or three. Obviously my 4TH antminer system is now the greatest bitcoin ASIC of all time by hashfast standards

There's no beating the difficulty. It's about contributing to it in the most cost effective way thereby making others contributions fruitless.

Bitcoin is becoming a rich man's game where only those willing to wager will have a chance. If any slowing of the difficulty is seen in the short term it's due to the cost of admission driving the little guy out. If the price of BTC remains high I suspect difficulty will begin to look like spikes as the large operations required to have a competitive edge come online. Building these systems takes time and won't necessarily reflect the steady outpouring of smaller systems.

The sensible money IMHO is to join in on one of these giant's enterprise.

Edit: The "sensible money" I use loosely when we are talking about bitcoin after all. If you have a mattress you might want to look at that option as being more sensible.

+1

I am scaling from 4kW to a 20kW location over the coming weeks at $0.135/kwh, with the goal being to then re-structure again and make the move to a full-fledged (100kW+) location in Quebec where power is about $0.10/kwh in late 2014 or early 2015. That's when you start looking at a million-dollar investment
2504  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales NEW STOCK ***NOW SHIPPING*** on: March 10, 2014, 10:32:36 PM
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.

I would say that 1.75-1.90 BTC is quite fair. Assuming a slight overclock of the cards can get 300GH, thats about 60% faster than an antminer that comfortably overclocks to 190GH at 1BTC.

Antminers use more power and are much bulkier, but come with fan and are more plug-and-play

2506  Alternate cryptocurrencies / Pools (Altcoins) / Re: [ANN][AUTO-SWITCH] Profit-switch auto-exchange pool: CleverMining.com on: March 10, 2014, 10:19:47 PM
why clevermining does not detect my real hasrate ? i should be 2gh/s and it only detects 100kh/s?

there is so much wrong with what you are asking...?

1) I doubt you have 2GH/s - you must mean 2Mh/s
2) your real hashrate is what clevermining reports.
3) it can take an hour to get any remotely useful statistics from the pool - have you waited at least an hour?
4) If it is detecting only 5% of your hashrate, there is something wrong with either your miner or your pool configuration
2507  Bitcoin / Hardware / Re: antminer help on: March 10, 2014, 09:43:41 PM
I'm not familiar with the term "HW Error", Is it another term for "Rejected"?
It means that the hardware sent back bogus data that doesn't make any sense - or at least isn't even normatively valid - usually as a result from it getting too hot.. temperature can do strange things to chips, like affecting path timing, making a signal B arrive before signal A, that sort of thing.
Some amount of hardware errors is pretty common, less than 1% hardware error rate is apparently acceptable for most hardware.  'The fewer the better' applies, but let's say you get 0.1% at 1GH/s vs 1% at 1.5GH/s.  Sure, there's 10 times as many errors - but this is a time-bound process, and you still get 1.49 times as many valid results in any given timeframe.
The flip side of course is that in pursuit of "LOL, MOAR RESULTS!", you can overclock it to the point where it burns out... literally.  And then you're getting zero valid results and a sadface.

29,908 hardware errors sounds like a lot, but since we don't know the timeframe or total number of hashes, you'd have to check the percentage.. and always keep an eye on the temperature.

I did the math for the error and it's 6.92442625514

Does this mean that the hardware is too hot?

probably too hot or overclocked a bit too far. If you are clocked above 375MHz, tune it down a notch or two. If you are not overclocked, check your power supply with a voltmeter and make sure its not outside of the ideal 11.8-12.6V range

How much does that actually help with airflow and cooling?  I am seriously considering this, but don't know if it actually helps or is just a bit gimmicky...

it definitely helps. However, there is a tradeoff between the extra fan cost ($15 for a good one with >70cfm) and how much more you will mine by overclocking an extra 5-10GH.
2510  Bitcoin / Hardware / Re: [Antminer S1 Sales open] Price changes daily, now 1.085 BTC for 180GH/s on: March 10, 2014, 02:34:53 AM
I have been mining with 2 units for about 3 days now on Eligius Pool, it appears that both units are making about .05 BTC per day with the current difficulty, I spent about 2.85 BTC plus 2 PSU for about $225, this is a test for me, thinking about buying about 20 units but wonder if it makes any business sense.

Could you guys tell me how much in BTC your machine is making?

Any input would be appreciated.

The real factor is electricity cost and required cooling.  Antminers generally make sense for anyone <0.15/kwh in a cooler climate or <$0.10/kwh in a warmer climate where airconditioning is a necessity.

Summer is coming, and there are going to be some very hot datacenters

This car would instantly extend your manliness by at least 2 inches, I'll have to pass tho, mine would become monstrous, haja!

Is someone willing to escrow my 11 BTC bid (still highest bid), so that I can take delivery of the car and insure that it gets me up to 3 inches before releasing my BTC to the seller?

I'll escrow your bid. But I doubt you'll meet his reserve...so keep on bidding up. Give'em at least 50K

Is anyone willing to provide escrow for allinvain's escrow?  I'm looking for double escrow protection, there is very serious money at stake here.

lol, double escrow eh. In the end escrow is only as safe as the last party to hold the funds or the first. You gain no additional protection from double escrow unless you do like a 50/50 split between two escrow agents. Or do something crazy like split it 10 ways, each escrow agent having on 10% of the funds.

But try not to stress yourself over such details bro, cause the seller did not even say he actually accepted your offer as a valid bid. This auction has a reserve or minimum bid anyways.

Now, seller, can you please post some pics of a few women in bikinis standing next to the car while there is a mountain of cocaine on the rear spoiler and stacks of money littered all over the body of the car.


I doubt the car will go for anything less than 80BTC, which would still be an absurd bargain. I would be happy to escrow if needed.

regarding multiple escrow, what you would want is an n-of-m escrow. An example of the way this works for a 3-of-4 escrow:
1) Find 2 escrow providers.
2) create a n-of-m transaction with 4 keys and 3 required for release.
3) give 1 key to each escrow agent, plus one to the buyer and one to the seller.
4) When the car is received and inspected, the buyer tells the escrow agents what to do (ie: dispute or release funds)
5) In order to achieve the 3/4 condition you need either both escrow agents to decide the deal is complete, or 1 escrow agent and the buyer. (The seller is assumed to already say 'yes')
6) if there is a dispute by the buyer; it means that for the funds to still release by 3-of-4 condition both escrow agents must agree with and side with the seller rather than the buyer - this should only occur if the buyer is making a frivolous dispute or trying to scam the seller.

This method can be scaled up to allow more 3rd parties to agree on the successful transaction to release the funds. for example a 5-of-7 would require the buyer + 3/5 agents to agree or 4/5 agents to agree against the will of the buyer

Looks like about 2.5 BTC per day.

http://eligius.st/~wizkid057/newstats/userstats.php/1JdrvUEgB1MHBEkdjq2BYEZ5oJd9dFKNto

That is only 5 cabinets of 20.

Also doesn't include our other equipment.

27 ants per cabinet. Each ant over clocked to 375 with an average hashrate of 190Gh/s or 5.13Th/s per cabinet.

That is beautiful. I just need to scale up from my current 7 antminers now Smiley
where are you running these? (power costs, geographically, co-location or private location, etc)
2516  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: March 09, 2014, 04:05:23 PM
Right now they are mining 50TH or so?  That's at 330mH chips.  I read somewhere (correct me if wrong) that new chips are 12.8GH each.

So that's 38.7x improvement in speed for gen3.  Using the same facilities from the 50TH they could get 2PH of mining revenue (if power was the same).  + additional from franchises.

Then chip sales.

All speculation.

not how it works. The old chips were 130nm. the new are 40nm.  (roughly 1/3rd = 9x the hashrate/power efficiency)

If the chip had the exact same footprint and power it would be about 2.5-3GH/s
Most likely the new chip will be larger and draw more power in order to attain the 12+Gh of the new chips, roughly 4x the size of the gen1 chips
2517  Bitcoin / Hardware / Re: Amazingly cheap FPGA miners on aliexpress - scam or not? on: March 09, 2014, 03:46:36 PM
Like others said too old/slow for Bitcoin mining now but you might be able to re-purpose them from something else, an alt SHA-256 coin perhaps, and technically FPGA's can be reprogrammed to do almost anything you want, unlike ASICs.

I doesn't seem like a scam, if you were going to scam someone you'd sell something worth $1000's. $16-$24 is probably not worth the risk/time of scammer.

an FPGA can already mine any SHA256 coin, lol Cheesy

There are two, easy to follow rules for posting in this thread which can be found in the original post.

They are:

1. Please do not post image macros.
2. Please do not post highly offensive or hurtful remarks. (swearing to express oneself is not an issue)

In addition to that, all trolling posts will be removed no matter who posts them and all posts made by well known trolls are automatically deleted.  If suspicious posts are made the posting history is examined and if necessary a warning is given to that person.  If they continue to troll they are asked to stop posting in the thread and if they ignore that instruction they are reported to the bitcointalk.org moderators who can then take action.

ActM Thread does not want to censor anyone and certainly doesn't want to have that reputation, however for the sake of genuine shareholders who deserve a clean thread it is necessary to continue to remove posts which don't follow these simple rules.

Regards,

ActM Thread

I have been censored from the thread countless times, and I dont think any of the posts were for trolling.

I own[ed] ACTM shares on btct, but sold them off when the trading went down. Looking back, I am glad I did so because there has been ZERO progress in the past (four?) months.

Initial proof of ACTM hashrate; competitor systems deployed in an actm datacenter  not a vote of confidence in your own stuff
55nm chips that are to be sold to 3rd parties and also mined with in ACTM's own data center? : cancelled all that work and investment down the drain - unless there was only a $1000 investment loss as suggested a few pages back?
28nm chips : announced as what seems like a delay and pacification tactic after the failure to create a working 55nm chip

I am trying hard to not be offensive and to stay on-topic. The problem is that ACTM is so far behind on all of its promises that there is little or no visible value to the company. At best, there are a few guys who have half-developed designs for a 55nm chip and perhaps a 1/4 scale drawing of it which they have labelled '28nm revision'

This is not trolling. This is asking for answers, proof, documents, ANYTHING BUT 'its covered by an NDA'
2519  Bitcoin / Hardware / Re: Introducing OneString miners - NEW LOWER PRICES on: March 08, 2014, 03:36:37 PM
Because of these lower prices, we will refund the price difference to previous orders, even the ones that already shipped.
Class act!  And yes, the auctions ended up ridiculously low - lessons for potential future auctions Smiley
The main purpose was publicity and exposure, and we got that for sure.


The auction works well for deciding an agreeable price that people will pay. There is nothing more embarrassing then to start an auction with too high a price and have no bids. (looking at you, avalon)

Hi Jack/asiabtc,

Please consider selling the ATX PCIe cables on their own. How much for 20 including shipping?

Also, I will be interested in the 15 Mh/s scrypt ASIC miner. Any idea on the cost? Please put me on the pre-order list.

price for 15 MH is 11000 USD, based only on pre-orders.


Ouch, is that the for sure price?
Seems a bit expensive if the new V2 miners are getting
3.8Mhs just buy 4 sets for $10k?
its different. new model is in rack case. and scrypt only.


Hi Jack, would it use the same chips as current miners but
with the SHA256 disabled or a new version of the chip?


yes. LA15MS is based on gc3355 but diable sha256.

so whats the point? For $11,000 I could build a fairly compact GPU farm that would probably be in the 13-17 Mhash range and retain full resale functionality. the only drawback is the power draw
