If you can find a fab in TO to do our designs and some 28nm chips magically become available probably cut time down a lot. In fact might be the way to go from the start depending on the chips.

problem is that most 28nm is all vaporware and preorders at the moment, i dont expect much great stuff to be available at competitive pricing until he spring. I would love to look into a local fab to supply the mining facility, but that presents a whole second set of logistics.

If someone in ontario wants to fab out mining equipment though, contact me because it would be a great partnership
2882  Bitcoin / Hardware / Re: [Setup & Troubleshoot] Bitmain AntMiner S1 180GH/S miner on: January 19, 2014, 03:47:05 PM
guys,  I am trying to connect PCIE with extender cable, after peel off the shield plastic, I realize the copper wire isn't too thick, is it normal? how do I know if the cable is not suitable to use if it's too thin? I can't take a photo as cable is too small for my phone camera to take a clear picture, please advise.

Power supply direct output cable marking: 18AWG

Extender marking: 22AWG


is it ok to use this extender cable?

avoid it is my suggestion. it will probably be fine as long as 1 entension per blade, but they will almost certainly get warm.

my experience:
20awg: running 3+ and 3- to each blade gets warm
18awg: running 3 is fine, running 2 is also slightly warm
14awg: running 1 and 1- is sufficient per blade and no warmth.

I would suggest using the thickest cables you can - it is cooler and easier of the PSU (to make wires warm means you're losing several watts between the PSU and the antminer)
2883  Bitcoin / Hardware / Re: [Guide] Dogie's Comprehensive Bitmain AntMiner S1 Setup on: January 19, 2014, 06:06:30 AM
So I'm looking at getting 2 of these, each with 2 blades. I'm debating about getting 2 CX600M PSUs (each has 2x6-pin PCIe). Alternatively, I'm looking for a single PSU that could power both. But I'm not sure of the wattage required. Dogie says to expect about 500w each, so I'd need more than 1,000w and 4xPCIe, right?

I was told someone was successfully running each miner on only 430w, and that 750-850 can run 2. Does that sound about right? If so, it dramatically decreases the cost of the power supply to run 2 of them!

Also, does each blade have an ethernet port, or the chassis itself?

I had a corsair CX600M running an antminer at 200GH just fine. I snipped the 8-pin ATX MOBO cable and ran 2*12V and 2*GND to each blade without issues. With the new antminer with PCI-e connections you shouldnt have any problems

1) at <44C you can overclock these a bit
2) as long as its still at 180GH you are fine - but a quick reboot should clear the x's back to o's

Thanks, I did a reboot and it worked. 

How many more fans will I need when I overclock it?

at least 7 ;P

1 fan to push exhaust warmth will help, but tbh it may not even be necessary as long as temps are under ~53 degrees

28nm equipment, 6-12 months is expected.

Why so long?

It could be a lot less, but 28nm will conceivably be the smallest bitcoin circuitry for a while until massive investments are made in 20nm technology - something not very accessible to anyone outside Intel/AMD

28nm machines should be able to run competitively for a lot longer then the current generation of 55/65nm stuff - almost comparable to the 7950's utility for GPU mining

The biggest obstacle in forming this collectivew will be the initial investment of equipment. At least 20kW of power use is needed to make renting a building a viable method and to encourage competitive electricity pricing. This means that if only ~10 THash of equipment owners are interested in hosting thier units with the collective, it may be necessary to raise a small investment towards quickly filling in the space with additional equipment.

if anyone here frequents the Toronto Bitcoin Meetups, I intend to be there this Wednesday to try and make some connections and find out if there are people there who are interested in joining the collective. I would be particularly interested in meeting anyone with plans or desire to manufacture their own mining machines (custom chip or based on an existing) but who does not yet have a buyer or location lined up for running said machines.

I want to get this off the ground in february, so that by March the collective is capable of accepting miners and running their own units. This is not a simple venture, so I am always looking for anyone with advice or insight into locations or power considerations

I would also love to find a way to monitor multiple distinct mining accounts via eligius or another <20% pool. As far as I know, there isn't a simple way to tracking 20+ accounts easily and reliably

how is that handling compared to the individual VGA heatsinks you were using? any increase in overclocking headroom, or is 38-40GH still the practical maximum?

Good morning everyone.   Turns out while waiting for the share log to merge into the main database lack of sleep caught up to me.  (I don't even remember moving from my office chair to my bedroom... I'll have to ask my g/f about that when she wakes up.)

Anyway, looks like the majority of the work finished while I was sleeping, so, I will work on getting replication going and proceed down my list above to get everything working again in the next few hours hopefully, barring and unforeseen challenges.

I have a few of these coins I would like to sell, and am looking for 2.30BTC.

I will post pictures in a few hours, but the coins were received by me directly from Mike Caldwell (proof available) and only handled once when transferring to airtites, using a fresh pair of nitrile gloves The coins are basically perfect specimens.

I can do face-to-face in the Greater Toronto Area (Ontario) or am willing to go through any reputable escrow service. buyer pays (and can choose) shipping method, but CanadaPost Xpresspost is my preference.




sorry for the mediocre image quality. The coins are in great condition and I can try to take better photographs of a single coin if asked.

Will also accept cash for face-to-face transactions, based on https://bitcoinaverage.com/#CAD + 15%

back up to the top now that BTC is surging and these coins are becoming fewer!  *with every coin sold my price increases*
2.3BTC - It can be any from the photo while available. All 1Ag6 batch  full album here http://share.pho.to/5rC0W

   

pleas note that the paper says "Tuesday, Apr 29". This photo was taken a month ago but coins are still available

2891  Bitcoin / Hardware / Re: Who here already pre-ordered the Monarch 28 nm Bitcoin mining card ??? on: January 18, 2014, 06:32:46 AM

a GPU with all this tubing etc. Clearly they don't get it and they don't understand where the next thing in mining is. They have chosen wrong. Very wrong. Also they don't include the psu's and the mobo you are going to need to do these in any sort of density. $$$ tis gonna cost you a lot more time as well setting these up and tweaking. Too much time.

These will all use USB cables for 99% of the 'lucky' owners - and will be a terrible mostrosity. It is amazing the poor design that BFL chose and stuck with. An honest man in thier shoes right now would go: "shit, we are behind schedule and our design is horrendous and matches no form-factor at all. Let's re-design this a a square, 4-chip board so that it can be stacked or encased easily and provide 2x the hashing power to our customers who have waited all this time"

But nope, these things are gonna take up 5 PCI slots with a big heavy radiator/pump, require host computers and be delivered astoundingly late to customers
2892  Economy / Service Discussion / Re: [In Talks] Klondike Mining Collective - Toronto, Ontario Mining Facility on: January 18, 2014, 02:44:06 AM
Looking at some of the options currently available, I am ready to do some interest checks for this.

For miners joining the collective with their own equipment, pricing will be done by power usage rather than speed or space requirements. This is to allow SCRYPT rigs to participate in the space and make managing different-efficiency hardware costs.

For a small collective (5-15 kW), it would be roughly $250/kW/month + power (includes cooling) = $450/kW/month total costs
For a larger collective (15-30 kW), it would be closer to $175/kW/month before power cost

Obviously power costs are significant, and the goal will be to evaluate if other electricity providers are available at more competitive rates. This will be an ongoing priority, and should result in power/cooling costs lower than mining at home.

For investors The 28nm generation will clearly be a priority to the collective, but is not necessarily the best price at the moment. By the time investments are called for, prices and equipment availability will be drastically different from right now, but to use a 'today example':

Based on the above prices, to add an Antminer to the facility (190GH/400W approx) would require:
+2.2 BTC purchase price (current BITMAIN price)
+$100 PSU + setup cost
+$160/month fees+hosting (based on the pricing for a larger collective)

With this pricing, You could have an Antminer system hosted with us for 4 months (long enough that mining profits approach zero) for only 2.6 BTC - you dont have to worry about power use, noise, or heat during the summer months. A quick calculation shows that within those 4 months the unit should enter profitability using these figures:
http://btcinvest.net/en/bitcoin-mining-profit-calculator.php?diff=1789546951&dcosts=2250&diff_mincrease=20&blpbtc=25&dhsmhs=190000&diff_mincreasedecrease=0.1&btcusd=900&dpowcon=0&btcusd_mincrease=0&pcost=0&calcweeks=22&dleadtime=1&action=calc

I believe the reality is much quicker based on a few of the recent <20% difficulty jumps



with all this in place, I've opened a poll to see what sort of interest there is.

2894  Economy / Service Discussion / [Testing Capacity] Klondike Mining Collective - Toronto, Ontario Mining Facility on: January 17, 2014, 09:22:38 PM
Klondike Mining Collective - est. 2014
Based in Toronto, Ontario, Canada

Currently 'on hold' while I test the capabilities of the location. With 7kW of my own power draw, (compared to 4kW planned originally), there may be less power/cooling then required to host as originally intended. I am monitoring this closely and if the location is well-suited to hosting much equipment outside my own I will continue to pursue a 60kW+ location for later in 2014

Ive been with these forums for a long time and became heavily involved with Bitcoin mining in late-2013 with the new generation of ASIC mining devices. However, I have reached the limits of residential mining and am looking to expand - and expand significantly.

I am not the only one in this boat. With many of the 110/130nm and 55/65nm technologies using major power draws, all over Canada Bitcoin miners are scrambling to find more electricity and space to keep from stagnating. The terrahash/second achievement is no longer enough to pay the bills on its own, and a central location with cheap plentiful power and a staff dedicated to 24/7 uptime becomes a necessity rather than a simple desire.

With that in mind - I suggest a mining collective be formed. By locating within the borders of canada's largest city, the collective will tout accessibility, responsibility, and accountability above all else. Every machine will be given individual worker accounts and payment addresses for simple, reliable tracking of stats and income, either via an established mining pool such as eligius or forming a private pool dedicated to network distribution.

This is not a task for one person - I am seeking miners, investors, and IT engineers to help make this a reality.

BITCOIN MINERS
We want to host your equipment! From 200 GHash to 5 THash, if you want to have your machines hosted at a secure location where you dont need to worry about power outtages, blown fuses, and cutting a holiday short because your machine went offline - I want to hear from you.

The initial location will have up to 20kW available for access, and can be expanded if that limit is reached. Estimated fees will include:
1) initial setup costs ($50-150 depending on type of machine and any complexity of setup)
2) rent+mainteneance+power+cooling will be roughly $0.27/kWh - this may fluctuate as cooling increases at summer and as there is more equipment to share the space rental
3) additional maintenance such as overclocking, tuning, replacing fans/PSUs, etc would be charged at a fixed rate (possibly $10/15min)

As mentioned, every member or machine would be given individual mining addresses to track, preventing any disagreement over mining income or dividends


BITCOIN INVESTORS
Want to participate in bitcoin mining but lack the space, time, or even funds to run your own units at home? Klondike Mining Collective has tons of room to grow, and is looking for investors who can make that happen.

The Collective will be constantly purchasing and adding equipment to the facility if calculations indicate that they will return a profit within 3 months. This means that if you had 2.2BTC to invest with us, we would purchase, host, and maintain a BITMAIN Antminer system in our facility on your behalf. It would be given a unique mining address (that is controlled by the collective) and its mining income would be split to 3 accounts -  
1) Hosting Cost - This would be the base rate for the unit's power consumption (incl. cooling) plus any relevant costs (including initial power supply and setup costs incurred) - for example: $100 initial cost for PSU, unit, and network setup, plus ongoing electricity at cost
1) Hosting Fees - This would include a small cost to employ IT engineers who maintain the facility plus a small share of the facility costs. - for example: 0.05BTC/device/month towards the cost of renting the location and paying the salaries of those who keep the unit running 24/7. This could would probably be adjusted lower monthly to reflect the lower income of the machine and the more machines in the collective = lower share of rent per machine
1) Mining Returns - This would be where all proceeds of mining go after the above reductions. The address will be unique to each machine so that investors can see the return-on-investment.

Machines puchased via investors will be owned by the collective, and operated under the above guidelines until such a time as the fees+costs outweigh the returns. For 55/65nm equipment, this is expected to be a 3-6 month time frame. For 28nm equipment, 6-12 months is expected.

The goal of the collective will be to select and maintain Bitcoin mining ASICs that will produce >120% ROI to the investor after the cost+fee deductions. Please understand that there are many varying opinions on what the ASICs will actually return and the collective cannot promise that a machine will actually produce more Bitcoin than it cost to purchase. However, It is my belief that a 120% return to the investor is entirely possible, with some machines recouping >50% of costs in a single month.

IT ENGINEERS
The collective is looking for a few talented individuals with experience in bitcoin mining and maintaining large device networks. There are very few openings for this role, and initially it would be desirable to give these to established bitcoin miners. MUST be located in the Toronto area


As the Klondike Mining Collective comes to reality, a board of members/investors will be formed to vote on decisions such as hosting fees, expansion, and investment options. This would begin with agreement on a selected location, selection of IT engineers, and determining how to invest in machines.

I look forwards to any interested parties. Please contact me by private message or TorontoMining@Outlook.com
2895  Bitcoin / Hardware / Re: [ANN] US/North American Bitfury sales NEW STOCK ***NOW SHIPPING*** on: January 17, 2014, 07:41:11 PM
new price is still too high, but less insulting. drop it to 200 and you can actually start moving inventory

$200 is unnecessarily low. I'd pay 0.40 BTC per card if shipped today, which is currently $325. So if the exchange rate were to jump up to $935 in the next couple hours, I'd buy more v1.2 cards. I'm more conservative in my hardware purchases than alot of people, so they definitely don't need to reduce the price any lower than $325 to keep sales flowing.

if you prefer to spend more money than make then yes. card running at 33ghs would not make its .4 btc back

I run mine at up to 39GH/card. But I pay over $0.30/kwh for electricity so the current prices (in BTC) are a bit too high for me.

  how did you get so high at 39Gh/s?


39GH/s is the average of the cards in my most optimized v2 rig. I raised the voltage to about 0.85v when idle. I never got around to checking when hot. And I spent alot of time finding the best speed settings per chip without overloading the VRMs. When the weather warms like in the last few days here, some cards' VRMs cut out until I tune down the chip speeds just a bit, usually just 2 chips at a time until it's stable again.

if you really think about how much work goes into fine tunning these things just to get a few extra satoshis over your investment. almost not worth it. i can be wrong, people can get pleasure out of this.... masochists Wink

If you can pull an extra 2-3GH per card with a bit of tuning, why not? however, i ve found the systems can get very picky if tuned to far and cause lots of headaches trying to correctly tweak every chip

So the news basically says five weeks to go - maybe 4 if you believe Jan 9th date - and the monarch card went from something resembling a GPU with shrouding to an ugly, watercooled motherf--ker.

The image below doesnt even have the tubing and radiator/pump on it yet. If this thing still connects to a PCI port, its going to take up about 3-5 slots with its terrible form factor. You would be excruciatingly lucky to fit 2 of them in even the biggest motherboard/case combo
