ANTMINER C1 Discussion and Support Thread

[notlist3d]

Seems my order was paid for, it indicates that on my order history.

I have two things to ask. How do you perform an SD card image flash? Or does it run off the SD card all the time?

Also, DOGIE, you indicated you need 1 litre of cooling liquid. That's ALOT of cooling liquid. Are you sure it is one litre and not 1 quart? And does the kit come with all the cooling liquid so you don't need to buy anymore? I may pick up an extra small quart, but wanted to know.

Thanks.

You will not need 1 liter with cutting cable using what they did.  I think I used around 600 ml, and Dogie was around 750 ml if i remember right.  The cutting of the cord directly reflects this.

The SD card image I uploaded you can use with Win32DiskImager to flash to micro sd.  You take the micro sd card out of the miner's beagle board controller and stick it in computer.  Most don't need to do this step.  It is just if your sd card is corrupt.

I try to change voltage settings: 0725, 0720, 0730
But power consumption the same - 865-870 Watt

Also I try 100 Mhz/400GH with 0600 and 0725 volt - power consumption is the same: about 335 Watt or 0.84W/GH

But I think that undervolting to 0.6 volt should get me about 0.5-0.6 W/GH

Why volt changing is  not working?

These PCBs may not have variable voltage control.

You shouldn't need to touch the SD card.

Uh..... 1 Litre = 1.0567qt   

You need 750-850ml and that leaves no safety margin, especially if you want longer tubes. Thats 0.66 - 0.75 in freedom units.

Is Corsair RM850 80+ Gold PSU enough for running one Antminer C1?

Is Corsair RM850 80+ Gold PSU enough for running one Antminer C1?

Yes, although I still prefer the 1000 as an investment if you're buying a new one.

[dogie]

More C1 stock added to batch 2.

Yes, although I still prefer the 1000 as an investment if you're buying a new one.

I can confirm the rm1000 is great with theses.  I had a cold ambient temps and PSU was in its "quiet" mode.

I have got conformation I am being sent 2 pumps as replacement's.   I bought a molex to fan connector so I don't have to worry about my wire frying boards.

All said it looks like I am losing around 2 weeks mining on 2 C1 machines.  Down 2 board fan controller's on 2 separate boards.  Lost higher priced coolant.  Paranoid and bought 2 extra pumps, and molex to fan boards.  With extra parts I ordered I am hoping to lose only around a week, but it came at a premium.

I will know more when I get all the parts from RMA.


I highly suggest 2 things after all of this so you don't lose mining time.  

• Order a extra pump (I went to ebay to get from closer location)
• Order a molex to fan power board (example http://www.amazon.com/Phobya-4-Pin-3-Pin-Splitter-Connection/dp/B007S3T4O0/ref=sr_1_3?ie=UTF8&qid=1415897694&sr=8-3&keywords=molex+to+fan        this is just 3 pin, the pumps they use are 4 pin, but they run off two through harness

Yes, the closer to about the 50% power limit you get the better the efficiency, so a more powerful power supply will actually save you money on average, if you can find the power supply for the same price.  I would recommend the EVGA 1300w G2, since you can get it for about the same price from newegg after rebate (if you don't mind MIR).

When will this batch ship out?

Where would buy extra pumps if you are in the US? Or does it matter what kind of pump, as long as it pumps enough coolant through?
Also, are the connections already attached to the pump when delivered? Cause I saw where you can attach multiple connections and the picture on syscoolings website of the pump looks a little different with the attachments. Do they just screw in? Asking a lot of questions because water cooling is a whole new arena for me and do like to have parts available.

With US I had trouble finding a pump for cheap with quicker shipping.  I turned to ebay and sorted by being in US and you can adjust location miles.  Then you can see estimated shipping dates.  The thing with ebay was LOTS of variety, and i was able to get a different brand.   Lots come from China, I just didn't have time with being down two miners.  Amazon has one that is close to kit http://www.amazon.com/gp/product/B00MB9EP3G/ref=s9_psimh_gw_p147_d0_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=center-2&pf_rd_r=0K2PSNFZTA9AHGE42714&pf_rd_t=101&pf_rd_p=1688200382&pf_rd_i=507846 .   But myself I wanted one's different then kit ive been messing with.

Maybe a stupid question, but would one of the following settings work:

a) Powering 2 blades with one 550 PSU and the other 2 blades with another 550 PSU
b) Powering 2 blades with one 650 PSU and the other 2 blades with one 550 PSU

?

Personally I would not do it I would go with RM-1000.  Even after miner is old and decommissioned you can reuse or sell PSU's.   I was saving a lot till i ran out of PSU's i used in old GPU days.

I'm sure someone will say that you can do it. And if everything works yes it would power it.   Possible problems if one PSU is down and one is up.  But I and most would not most likely

[mavericklm]

does it matter? amperage above 15A/ board most important, and preferable with 2*6pin, not just one 6pin
i got 1psu/1 blade

Well if your blade with water pump and radiator goes down and it still runs.... not really good
Or if one that controls fan in front goes down and it keeps running... not really good either.

[mavericklm]

then isn't it better to put the pump totally separated and is there a shut down based on temperature or somekind of halt the mining!?

I ended up getting a molex to 3 pin power board to run my pump and fans.   As long as power is on my pump is pumping.  I will know how well it works once I get my pumps ... again.

Hm, I may give it a try... I still have so many PSUs from the old days....

[mavericklm]

if there is a master blade like in s1 and s3, then i think is best to use a molex from the same power as that blade

[dogie]

Order a extra pump (I went to ebay to get from closer location)

Which did you get? There are a few similar pump models which aren't as powerful.
