ANTMINER C1 Discussion and Support Thread

[psalm69]

I needed to replace one of the water tubing , so powered down both C1's overnight & bought some new pvc, which arrived after a few days. One C1 powers up ok & starts hashing. The 2nd has a ethernet link light but no ip. Checked dhcp, the default ip of 99 and the static it had previously but nothing. Tried factory reset, the red blinks but no response from http or ping still. Does this have a serial boot console ? Is my only option a SD boot recovery image ?
thanks

I would suggest using a 2nd microSD to do it.  But I  would try the image on it.  If it's just IP problem that will reset it to  factory IP

Replacing the microSD fixed the problem. I wish there was a start/stop cgminer button, as trying to configure it while keeps restarting cgminer was annoying.

thanks again.

Will there be another generation of water cooled miners? Some user's just can't run something in their homes that sound like an airplane taking off the runway. I'd love to see a more efficient water cooled model running at least 2+ TH/sec. This 800watt for 1TH is getting expensive.

Syscooling sells a S5 kit to convert to water cooled.  I personally don't think we will see a C2 since they went to selling a kit.   But I could be wrong.

Where is this kit? And to be honest, I've had so much trouble with my C1 pumps I doubt I would go for the kit anyway. Kind of gives me a sting when I think about it. I could see if the S5 had a lot more hashing power, but it's only 1100. There is a $15/month in electric costs if I were to buy an S5, but I can't have anything noisy running in the house anyway. Even if in another room, it just has to be quiet.

4x S5 =4,6TH/s

This cooling kit is for just one 1 S5? How many can it cool?

[opentoe]

Adding $119 (cooling kit) and then another $130 (modified kit) to fit an S5 is an additional $250. That alone is almost the price of a C1. Too much work and money involved there just to save 200 watts per month.

You save 800watts (200wattsx4) and hash 0.6TH/s faster.

Unless you have really expensive electricity it will take a long time to pay off the additional.  I know myself I'm around 1.82 for the 800 watts.   250/1.82 (per day) is over 137 day's to pay just the kit's off.   That does not include shipping which if it's like when I got my C1 kit's off them is pretty expensive.   It's safe to say payoff is farther then I would go considering I can do it all with air for not any more expense on kits.

Bitmain should then provide a bundle with syscooling on a kit to lower the price.

[rpandassociates]

hahaha bitmain needs to do alot of things understatement of the year
I would love to see them put out a water cooled S5 should be branded C2

Biggest thing bitmain has to do is straighten out their firmware issues

And why retire the S3 already when thats whats inside the C1 4 S3 boards

Its bad to retire a product before people have ROI on it

its not 200 watts per month its 200watts every millisecond

Your electricity is billed per KWH (kilowatts per hour) every second minute hour
hell if my C1 ran 800watts for the whole month I would be loving it...... that would be like 30watts a day hahaha wouldnt that be nice

this is one of many electricity calculators
http://www.rapidtables.com/calc/electric/energy-consumption-calculator.htm

Lets take a Antminer S5 for example
590w @ 1.15Ths
thats 14.16kwh per day x .11 per kwh (my cost)='s ($1.55)

from my experience every TH earns a bit over .01BTC per day
for 1.15THS (antminer S5) 0.01244386 BTC

now of course this depends alot on the pool you are mining in. Pool luck etc.
eligius pool and similar pools will pay the above
at slushs pool you could earn more or less depending on how many blocks they find
with 4.5 ths @ slushs  pool i make .011 every block wether the block takes 20mins or 24hrs So on the good days they find 7+ blocks on the bad days like today they only found 1 block in 24hrs horrible !!!!!
at eligius 4.5 THs brings in 0.05316924 BTC per day

Dunand didn't read the entire thread/situation, hence just throwing numbers out there, confusing everyone. I know what it cost to run an 800 watt device with my electrical costs at $.10 to 11 kwh. I'm still in the black and next month may even make more. This thread apparently just died out and either everyone's C1's have died already or they are running perfect. It is a little off to see no activity in a products thread that supposedly sold so many. Very strange. And you can bet the ones that haven't sold yet are running right now.

It is impossible to find 8mm/10mm hose in America. What would be the equivalent in standard on those dimensions? I know 8mm - 15/16, but what does 10mm come out to be on a popular coolant hose size?

3/8 inside diameter.

Thanks. Does anyone have a link to the right size tubing for these setups? FrozenCPU is out of the question of course since they aren't doing any business right now. 3/8 must be real close to 5/16 because on a box of Mastercleer tubing I bought a while ago (N8  8mm\10mm) right on the box is also said ID 5/16. I bet both tubing sizes will work, one just may be a bit tighter. Well, if anyone has a link to the correct stuff in the US, can you sling it in a response? Thanks.

The syscooling kit radiator for the S5 is huge. It's almost as big as a small cars radiator. I would still be interested probably since its eating less power. I live in a single family ranch style house. 3 bedrooms, 2 baths, kitchen, living room, nothing special. You should see my electric bill just from having the three C1's running. I had to switch to the equal payment plan so I wouldn't be surprised with these huge electric bills and can budget much easier.

I think the problem is amount of trouble it can be.  If you look here it's full of troubles (In my opinion it is the kit that caused this, specifically pumps).   I don't see there being a C2.  

I had to "mod" mine to get stability.  I switched to a molex to 3 pin adapter.   With this it does not try to take power from your PCI-e cables or from miner.   I also bought a pump on ebay.  That pump is still working great on two of them.

I feel your pain you should have seen my bills when I was running approx 12400 watts worth of mining gear.    I have started to get ready for summer and got rid of my 1T Dragon and my S3's.

You know it's bad when your electric company does not support one payment for your amount your paying.  They had to do two charges for me to pay per month to pay complete bill.

4x S5 =4,6TH/s

This cooling kit is for just one 1 S5? How many can it cool?

The max power dissapitation is 3500w

SC-BC2 Cooling kit sould support 4 sets C1 miners.

Cools off perfectly 4 Antminer S5.

3X  ANT BC1 mining cooling kit  Cools off 2 Antminer S5. 1x pump and 3x AT360 radiator assembled together. With 9 fan, only one side of the radiators.
Not that I would recommend it (3X  ANT BC1 mining cooling kit radiators), SC-BC2 Cooling kit  is a much better, but I  already had 6 of   them from C1 kit.

[rpandassociates]

My mine Consist of a mix of 6 S3+'s 2 C1's and 2 S4's got 2 S5's showing up tomorrow believe me when I say I understand the power bill. Wife complains about all of the noise good thing she doesnt see the electric bill haha  

And yes I am considering offloading the S3+'s they recently ROI but I want to see them profit before they go. The price is way down on these they are going on ebay for $100-$150 tops and considering I paid $450 for them well just hard to let them go at that price. they still bring in 505ghs at 400+watts each (overclocked ofcourse) BTW I never OC until the warranty is over

I got my S4's used from gawminers for $475 so that was a bargain and they will ROI quickly unfortunately I do not dare try to OC them as the stock power supply is already damn near at its max

My C1's go out of warranty next month and i run each one on its own 1300w evga G2 PSU's So i can OC them but from what i have heard theres not alot of advantage to OCing  them especially when they already pull 800+ watts at 1.1ths

Cant wait to get these S5's tomorrow not a big fan of the case not having a top and still working out  the details of how to heat exhaust them efficiently, a top venting case just doesnt configure well into my current racks. Nor am i big fan of the case period plastic and stuff ugh bad design period so I do like the water cooled concept but at those kit prices they seem a little to high.

I like my C1's and have had very little issues with them they are batch 2 I run my pumps-fans off of the PSU periph plugs instead of the boards, runninig of the boards is just crazy idea, dont know what genious at syscooling thought that up, then again i would say syscooling has a serious lack of geniuses haha I run mine on these pumps http://www.ebay.com/itm/500L-H-10W-DC-12V-Water-Cooling-DC-Pump-Tank-250ML-F-pc-CPU-CO2-Water-Cooled-/111241824048?pt=LH_DefaultDomain_0&hash=item19e6878730
and have the syscooling junk pumps as backups. I considered buying swifttech pumps but they are crazy expensive.
and well a water pump is a water pump it does not have to be fancy just needs to work without failing. Hell you could use a washdown pump for a boat if you wanted just comes down to watts used. I seen some cool systems on youtube people cooling multiple C1's with all kinds of methods car radiators and such one guy even used geo thermal now that was inventive.

I myself would love to chuck all these miners in a 3m novek immersion tank that stuff is so expensive though. https://www.facebook.com/3MNovecdatacentercooling https://bitcointalk.org/index.php?topic=655464.0
they need to make a at home kit for us home miners

then when it comes to cooling you could do something out the ordinary like this ?

Would the standard radiator not do much more cooling?   I don't have experience with a fish tank chiller but I find it hard to think it will cool down the liquid as much as a 3 fan radiator.

those will not work.  you need a phase-change air cooled refrigerated cooler. You will then need a mixing tank and two pumps.  You can use a drinking fountain water chiller (elkay) but that will only work for about 1-2 miners max. 
if you don't want refrigerated, try this:

he will go down to 700 + shipping.

yeah the aquarium one probably would not be sufficent just saying theres other methods or cooling   Some out of the box thinking the 3m novek is a awesome proven method, similar to mineral oil submerged cooling but cleaner and less hassle. But one has to wonder about some of these industrial water chillers wether they be refrigerant or peltier

The last one is an idea, but you will need a way to supply cooling fluid, so again that will not completely work.  So why try to cool something that is cooling something?  peltier systems will not work as one side of the unit must be cooled off.  peltier systems are heat pumps, not cooling systems. 

And it really depends on how many miners. C1's are really for a place that have ample supply of chilled water, say from an HVAC system or can piggy back on a boiler condensation system.  They work as home miners too, but in that application, the blowing is just transfered to a different part of the house.  in other words, you either blow air where the miner is located, or you blow air somewhere else.  either way your blowing.

The math does not really add still though.  The standard radiator is much cheaper.  And because of speed of mining technology I would hate to spend enough to tie into housing systems.

currently i use the miners to heat my home, have yet to turn on the heater this winter, just turned my rack around from blowing outside to blowing into a fan that directs it towards the air intake for the central AC system. Summers coming though and I am in process of building a small room in the garage that will vent the exhaust into the attic. and will tie the small room into the central AC or get a small portable AC unit. Do not want to AC the entire garage. Still working out the CFM requirements.

I wanted to use a evaporative cooler instead of a AC but I live in Florida and from what i read its way to humid to use them effectively here. Unless i drop the humidity level in  the garage which means using a dehumidifier so between the swamp cooler and dehumidifer power consumption might as well just run a portable AC or tie into the central AC system. The advantages of the portable AC would be temp control as it would not rely on the thermostat which doesnt read the miner room.

Now if i could just find a 10KW solar panel system for less than 20k wish i lived in a state where i could effectively use a wind turbine. Or where electricity was cheaper i.e in Washington by the hydro electric dam.

Well my last Syscooling pump died on me yesterday. I knew it would happen, since I've went through about 5 of them myself. I've switched over to that one from Ebay, which has been working fine. New hoses, a couple kill coils and feser one coolant I "should" be good for a while. I don't know how 50000 rated pumps die so quickly? Maybe they meant to say 500 hour?

any more problems with the aluminium corrosion?
