ANTMINER C1 Discussion and Support Thread

[notlist3d]

I run at 1.007TH/s on 2 miners with stock setting. I want my 0.001TH/s Bitmain!

Joke aside you don't have more clues about your corrosion/pump problem Opentoe?

Total of 6 C1's and 4 pumps already died. In the processing RMA'ing the last two. The one that just got replaced died on me again, so this is a second time it is going to get replaced. Ironically the miner that forced me to keep the fill cap open is currently running on a different pump with the fill cap closed. No pressure being created inside. Same exact thing is happening to my father C1's now. He has to keep the fill cap open. I suggested to him to RMA the pump to begin with and try another type of pump. The loop is supposed to he closed so no air/contaminants get inside to corrode the coolant. Soon as my father receives his "other" non syscooling pump and it works with a sealed closed looped with no builded pressure, then the problem points to the pumps.

He flushed his entire system out last Sunday. Cleaned everything out and filled the loop with distilled water and a couple kill coils. Give it an hour, unscrew the fill cap and already you can hear the air escaping. I seriously thing some of the pumps are cavitating maybe creating air in the loop and slowly builds up. i don't even have to use the hose clamps if I didn't want to, since no pressure builds up at all. Algae my A$$.

We are in the process of elimination right now, and so far right now everything is pointing to the pump. Apparently this outcome is not happening on all the pumps, since I still have two right now working fine with a closed loosed.

I'll be shipping out my two defective pumps out to tomorrow vis UPS. One doesn't turn on at all and the other will run for 20 minutes and then just stop.

It stinks to put extra money in them.  But since i bought the ebay pump and molex to 3 pin adapter my life got much easier.   I suggest you think about it to get stability.

As far as the one that one that has weird pressure and ugly buildup I don't think above will fix it.  You might eventually take it apart to look at cooling blocks.  But that would be a huge pain to put back together.

The weird pressure one is fixed. I got my hands on one of those Ebay pumps, dumped the dirty hoses and flushed out all the old stuff the best I could and even tried that Ironside coolant again (blue this time) and it is running fine. I'm still getting my original defective pumps replaced for back up purposes only. My father is going through the same problems right now, so I'm trying to help him out. I told him to RMA his pump that seized up, but is still going to purchase that one from Ebay which is working ok with mine. He's first going to try it with distilled water and kill coils, and if that doesn't work will try some special coolant he found on FrozenCPU. We are still getting a return on each C1 running then at home, it's not a lot but we want to keep them going for as long as possible. We need to shoot some Viagra into the bitcoin USD/price.

Distilled water with a kill coil is insufficient..

The kill coil (silver) acts as a Biocide (only) to stop algae.

You also need an anti-corrosive additive in your Distilled water.

The pre-mixed coolants have all the additives already in them to stop corrosion and bacteria.

I have had good results with this
http://www.frozencpu.com/products/17472/ex-liq-262/XSPC_EC6_High_Performance_Liquid_Cooling_Premix_Coolant_-_1L_-_UV_Green.html

The thing is I think he mentioned it happened in a hour.   That seems very quick to be corrosion and bacteria to the level he showed.  I personally use coolant aswell in mine.  But I think a hour is awful quick for the amount of build up for it to be corrosion unless the inside is just horrible.

Sure, an hour after they were ran for 4 weeks.
Not out of the box.

Even Bitmain warned users to use a specialized coolant
* Coolant: If you choose an aluminum radiator, you can use deionized water with an additive, or specialist coolant.
If you buy a copper radiator, you must only use specialist coolant.

When they talk about an additive, they aren't just talking about a kill coil (silver)
they are also talking about an anti-corrosion additive

At elevated temperatures, I would think the corrosion process would accelerate.

There was a problem with the pump. It was the second pump that failed and now my father's pumps are starting to fail. These are are from the very first batches of the C1. When pumps fail on 1 or 2 out of 6 it is coincidence, but when they start to fail on 4 or more out of the 6 then it turns into a fact. I hope the alternative pump I've been using holds up. When I switched it to the syscooling pump air pressure would gain in the loop within an hour. Then I switched it to the alternative pump I purchased on my own and has been running closed loop no air pressure problems for several days now. If it was the syscooling pump I'd have a small explosion. Nothing else was changed. Once I found out the syscooling pump was somehow sucking air into my loop or cavitating bubbles from all the testing I've done, then I cleaned out the system and tried the Ironside Coolant again which is pre-mix. It's just nice to know when I come home I won't have water all over the place and possible dead C1. That's the short story.

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.

@Evan,

Give us a bit to get you more clarified answer for this.

Thank you for bringing it up to our attention

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.

I don't like their site as far as ordering.  You can see the last so many orders.   On this I think we are seeing every order they have had, and I think they have only sold 6 of these kits.

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.

You can run 4 S5's from buying each one of those kits?

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

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?
