ANTMINER C1 Discussion and Support Thread

[mirahan]

I wound up not having to reset.
Got the miner on my primary router and the IP address was different than what the seller told me somehow.
I found the unit on my network and simply navigated to it.
Mining to Kano's pool right now at right at ~1,000 GH/S

Thanks for the help! Glad I didn't have to reset!

Getting my first C1 later this week with a new and dry cooling kit. What's the best coolant options to fill it with? Looking for max cooling to keep fan noise low.

The best mix is 10% antifreeze concentrate + 90% distilled water.

I've had good luck with this coolant:

Distilled Water...

I used a water-cooled Antminer  S5  only 48 hour with distilled water .  After the first over heating due to the pump failure and  switched off, I also got this "disease" . See the photos from opentoe

Treatments with anti-freeze and everything is fine.

I personally went with coolant and it might be luck but I have never got the "disease" (Also using different pumps could be part of it).   Only bad thing about coolant is if you syscooling pump leaks then you are loosing money from re-buying coolant.

Summer coming.  Adding a little water to the tank every day or two.  Without the sharp cornered Syscooling and only the champer edge Syscooling in place no refilling necessary.  So, tho there is no detectable leak a little water is going somewhere with the after market Syscooling pump in place.  With summer in mind I bit the bullet and bought one of those large tall tank pumps but from China.  No rush I figure.

I think you will love the tank.  I have been running it so long on those and no issues.   I have a extra bottle of coolant in case of summe heat needing it.

So far it's been able to handle mid 70 degree days and no issues.

I find it interesting Syscooling was last Active: March 21, 2015, 09:35:43 AM

I am just hoping this means there will never be a product again with them as a supplier of parts.   I would love a C2 with a proper water cooling vendor if they ever do it.

No one was forced to buy the kit from syscooling. There is a lot of place where you can buy watercooling supplies.

[dunand]

I tested underclocking-volting the C1.

The best setting was suggested by another user 2 weeks ago:

675/200 530W  803Mhs 0.66W/Mhs
760/250 790W 1008Mhs 0.783W/Mhs

FYI I have an EVGA 1300W gold.

I'm not going to fight you over it, your comment is not needed.  I will ask did you have the first rendition of electrical wire and get first batch as soon as they started shipping?  I was thinking you were later on in this thread buying a decent amount after they first started shipping.  I think your experience is different then many who got very first ones.

Now that people are getting them through bitmain kits it's cheaper price and better customer service in my personal opinion.

Thank you for posting these.  I appreciate you sharing them.  As it's getting summer time I chances are will be looking to underclock soon.

Yes by chance I buyed in the second batch.

I won't take away and turn this into a basing thread.  Just syscooling and batch one was not a good mix.  I have had lots of bitmain products and never been treated like I was during that.  But again it's in the past and I think Bitmain did a great service to buyers to carry the product themself.  It was cheaper and you get better service.

And also thanks for sharing underclock I appreciate that.

Wish he had included F° & inHg.  And is the supply on 120vac or 230vac?  I'm jealous 'cause I don't get anywhere near that W/GH/s with my exceptionally cheap power supplies @ 250M/0760.

120vac recorded at the wall with a kill-a-watt. It's 21-22C around the miner 32C in the miner web admin. It was 36C with the default setting.

Just did this yesterday, kill-a-watt, 118vac, ambient 79.95°F, 29.52inHg, 250M/0760, 1002.88GH/s(avg) 819watts, 1.233GH/s/w .811w/GH/s.

Then at ambient 77.9°F, 29.54inHg, 243.75M/0675, 982.76GH/s(avg) 792watts, 1.241GH/s/w .8059 w/GH/s.

I'd decided to run my C1's at 243.75M/0675 to reduce the current away from max on that circuit.  After I characterize my S3+'s I'll come back and look at 200M/0675 because that frequency agrees with best I found on an S3 but happened to be at the coolest point in the day.


I'd appreciate your feedback when you get to 80°F ambient.  I know these are less efficient power supplies and my initial application was at ½ full load capacity but with the C1's they at 56.9% of full capacity each.

Running at 243.75M/0675 @ 79.9°F my hashboards read 35,38,36,38 & 981.12GH/s(avg).

I had wondered once about an air mass flow sensor and if it would applicable here.  But, the LM75A could generate data that would simulate an air mass flow sensor output.  So, air flow ability to cool ASICs should determine fan speed.  If fan speed is increased according to a formula calculated at sea level it would be less than optimal on a humid day or at higher altitudes.  If the fan speed is determined by the LM75A state and increased to lower the LM75A output, then the air's mass is less a factor.  I wonder which it is.

I tried 0675V/200 - working but with  x
With 0700V I never had any x on the same machine.
