ANTMINER C1 Discussion and Support Thread

[dogie]

Hi guys -

Just put my C1 together. Prior to upgrading to latest firmware, all chains showed X across each row...  Now I show this weird thing in chain 1 and a few X's on chain 4...

Any thoughts?  I am using RM-1000 PSU.

What voltage and speed are they on now? Different firmwares have different defaults.

243.75 freq
0730 voltage

959.53GH average.

Take the case off and have a check for leaks, when you start dropping chips entirely (-'s or just nothing) then its worth inspecting the boards if you can.

Interesting.  36.9°F outside.  Inside is 63.9°.  Maybe it's my connection or maybe it's the pool but my hashrate goes though a long slow rise then fall and so on.  The temperature of the water out port of the water block is cool to the touch while the air pushed thru the C1 is quite warm on exit, warmer than the exiting water.  I just unplugged the single fan so the two closest radiator fans to the ports run.  I wonder if letting the C1 mounted fan run at 12v continually would be a good idea.  Since disconnecting the single radiator fan the C1 mounted fan has started changing speed fairly often.  The hashrate has come up but that might just be the observed cycle.

Odd.  GUI Fan2 speed indication never changes from 1200 although I hear it increasing and decreasing.

If its annoying you can try plugging the fan into the other header that it can reach. You'll have to take the case off unfortunately (and all the PCI-E's) to get to it though.

You sure you pump seems to be running okay? I can't think of a reason why the fluid exhaust would be cooler than the air exhaust.

It's clear that drawing air in from outside, outside at 36.9°F, that coolant is going to chill.  The miner was in a room at 63.9 beneath the window.  Those temps were last night.

I checked earlier this afternoon.  Outside ~43°, inside 66°, air measured inside the rad exhausting into the room from  outside, ~70°, air at exhaust of the C1, 99-100°.
--------------

I'd link to see springs for the outlets that allow the hose to make a curve without collapsing.   I probably want to put the fans on the other side of the rad on the same side as the hoses.  In cold weather that would put the hoses inside while drawing in and warming outside air.  I could always switch back in late spring.  As it is I just rearranged a bit of foam from packing that I had taking up the remainder of the window width.  It pressed against the hose and restricted a little.  GH/s dropped into the low 900's.  Hashrate has come back since cutting out a piece that compressed the hose a bit.

My mistake.  The fans are already on the side of the ports.  I just need to flip them to reverse the rad.

You can buy them online pretty cheap, I put them on mine. The colder you get your tubes the less ductile they'll become as well.

after some repairing from my broken C1 i finally fixed it. it now runs STEADY on 1045 GH/S

What mods to original did you do may I ask?

replaced the cooling block and all other cooling, which was totally destroyed from shipping (they shipped my C1 with water in the block which had made t he whole unit to Rust on the way to me so the miner was all wet with brown rust water everywhere.
so i basically only replaced the cooling

Take any photos of the rip down and repair?  Particularly the quality of thermal paste application.

i never took any photos durning repair i can get some of the new fix later

Has anyone run two C1's on a single syscool cooling setup? One pump One Radiator?

I don't think it'll work unless you're stating with an upgraded pump and radiator and not the one that comes with the system (my one C1 now gets pretty hot now by its self and remember you're not supposed to go much over 50 in water cooling as the acrylic and plastics will start losing shape at around 60 from what I've read).  I'm going to be trying to do a 2 or 3 C1 system shortly, but I've ordered a different pump and two 420 x 140 x 80 mm radiators.  I'm going to see if that's enough to cool 2 C1's and then try to add a 3rd if it's low enough with the 2.  Set up will be C1 - Radiator - C1 -Radiator (C1 if possible) reservoir/pump.  My since C1 now runs about 770watts at the power supply, but sometimes climes up to 860 for some reason.  A 1600 watt power supply should handle the 2 at 770watts (pushing it though), but not at 1720 watts, but if I add the third C1 then two 1600w power supplies should be fine.

At the moment I have only 1 c1 so i don't need to think about this too much, but they do make these,

http://www.syscooling.com/products/water_cooling_kits_for_Avalon_II_BTC_mine/2014/1211/635.html

you can compare it to the standard supply

http://www.syscooling.com/products/water_cooling_kits_for_Avalon_II_BTC_mine/2014/1212/637.html

In the end it's all about you local conditions on whether a single rig setup can handle 2 C1's if they are in a nice cold room and you rad's are getting nice cold air going through them possibly. Otherwise you will just run you C1's too hot and shorten their life.

You can also see that the pump in the multi rig kit is a by the looks of it 750 lph compared to 450 lph and over twice the head. Things are never as easy as it seems.

Cheers

I wanted to order that myself, but when I saw shipping was more than the unit its self I decided to go with separate components.

Not to sound rude but this statement cant be correct. Aluminum doesnt rust and the cooling kit and water blocks used are all aluminum not copper and aluminum mixed so there cant be any rust because aluminum corrodes not rusts and since the rads and blocks r aluminum they dont have that reaction that copper blocks have when using an aluminum radiator or the other way around so can u take some pics of what you mentioned cause im really wonderin wth ur talkin about lol.

If it is blocked up with rust then u could have easily taken some cheap clr from home depot and pumped it through the block but again aluminum doesnt rust lol. If it did everyones polished aluminum trim on some model cars would turn to orangish brownish pieces within a few days of being outside since the aluminum trim isnt coated like plastic and steel is with crome to prevent oxidation or whatever.

If u replaced the blocks wanna sell me the old ones ??

My screws had some rust on them when I got my C1 and saw there was a little fluid still left.  I don't think he meant the cooling system itself.

I found an old picture
This is AFTER i cleaned the rust. when i finally got my water pump the Cooling blocks were leaking water on all the Connections and even at one of the corner of the block (on the front )

Clips made of cheap steel is the source of the rust.

I want to know if anyone installed multiple C1 in series. For example, if you have 2 C1:

pump#1 > miner#1 > radiator#1 > pump#2 > miner#2 > radiator#2 > pump#1 > ...

I'm looking for redundancy if 1 pump die the miner can still run. Also, I'm looking to use a larger radiator for multiple miners and I want to know if it's a good idea to run them in series. In the end, I want to do something like this:
pump#1 > miner#1 > pump#2 > miner#2 > badAssRadiator > pump#1 > ...

I know miner#2 will run hotter than miner#1 but in average they should run at the same temperature than having them run side by side with a splitter.

I know they made one kit with a huge radiator that was sold for multiple units.    Don't think I have seen anyone take pictures of using it.

i just got my c1 today with included water cooling, i used some blood red chillblast with A little water as the large bottle was not enough. what i am concerned with is it keeps turning off as to high temperatures 80 degrees + when it says it should only be hitting like 50. when i touch the radiator, psu, and c1 exteriors they are definitely not warm to the touch in any way. ANy help would be appreciated!

Does not sound like the coolant is circulating.  Are your tubes set up correctly?
