ANTMINER C1 Discussion and Support Thread

Yer, i will contact ebay but it all takes time.  21 days have to pass before i get a refund.  Plus he will have to pay for postage cos i will not part with more money...Meantime i will get it hashing for me. $$$ 

Will not buy anything at all, just cobble it with old junk.  Alley freezer rad and plant irigation pump. it only has to run for a month!

The PSU is a Dell 750w NT50P-S1 for a server, they are good PSUs i have them running my S3+ and my underclocked S1s
So... 750w PSU with 4 leads.  each lead has 15A / 12v 6pinPci-e.

I plan to connect two power leads (30A) to blade #1.
another pair power leads (30A) to blade two.
if it works it should pull around 500w with two blades

Then i underclock to 200Mhz @ 0.720v with two blades hashing and check power at the wall
Then power down and reconnect the PSU.
I then plan to connect one power lead to blade #1 (15A),
2nd power lead to blade #2 (15A),
3rd to blade #3 (15A),
4th to blade #4 (15A),

Should hash at about 800Gh/s @ 650w  ??

@notlist3d  you said in your post  "It's hard to tell from description on what radiator actually does in terms of cooling.   It likely is highest costing accessory."

Is the rad an "accessory"?  I can run without it if it is only an accessory! 

It is quite a big rad from a freezer.  It will take 4 off 120mm fans and has 12mm hose barbs. It holds about 1200ml.

I do not mean it as accessory you can run without.  At the beginning you bought the miner from Bitmain, and a acessory pack of such for water cooling from syscooling.  Eventually I think you could get all from bitmain (been a while so could be wrong).

These "acessory's" are NEEDED to run with watercooling its just a lot more complicated then one fan  with say the S3 brother of the C1.   Things such as radiator, fans, tubing, Barbs, Liquid, Pump.  But if you have all that and no extra money spent I can see why you want to get it running.

With all the watercooling parts, and miner even underclocked will not be as efficient as a S5.  And make sure all hashing blades work, as seller does not seem to be honest.   I think you honestly are better off returning it via paypal... but that is my opinion.  Are you running on free electricity?

Ok, cos in my world an accessory is an optional extra.  You mean a radiator is a necessity.
No not free electric. If i ca get 0.8w/gh I am happy @800Gh/s.  Bitcoin is on the up again.
I will be wanting a full refund from paypay.  It was sold as not working, (unable to test) OK but it was advertised as an S5.

I only buy broken stuff and fix it up.  I got kit for replacing components on PCBs and loads of test gear, scopes, sig gennies, decade boxes, desolder, solderstation, gas pencil, small irons (8w, 35w, 55w), big irons (100w, 400w, 600w) stock surface mount fin pitch components, bla, bla, etc etc...  I get board and its more fun than jigsaws

But when talking about water system it obviously is necessary as that's what you get your cooling from.  But I can see your point.   I can see your wanting to do this project so instead of telling you my speculation in cost vs what it is worth, I will wish you the best of luck.

I'm riviving this thread to show you a project I did in 2015.

I was heating a pool and cooling two Antminer C1. The miners were running super cool and the pool was a lot more enjoyable. Because were I live a pool rarely goes higher than 25.5C (85F) without heating. I was running two C1 in series with one pump and a stainless coil in a pool for cooling.
