ANTMINER C1 Discussion and Support Thread

[opentoe]

How can one of my father's C1's be 1000 watts at the wall? Freq is on default and voltage is only 730 or less. But his P3 meter is indicating this C1 minter is pulling over 1000 watts. What's going on here Bitmain? He had to do a cold reset and that finally brought it down to 800, which is still a little high. Have to keep an eye on things daily which is starting to be a pain in the ass. 800 watts it what it is supposed to be. I think there needs to be a new more solid firmware written to possibly take care of some memory leaks and watts increasing like that.

My 20 miners are NOT STARTING!
It was running between 50+ to 60+ degrees, hence I decided to stop it and re-position the entire rack placement and put in extra air-conditioning to the room which took me about a week plus.
Now when its all good and I try to restart my miners, it would not start at all.

Powered it on, as usual the cold-start sound for less than a minute then it turned silent.
But it did not turn up on the designated IP address.

Tried restarted it couple of times, still the same.
Noticed both Green and Orange LED lights was up, tried to look for answers online(nothing much).

Tried factory reset, paperclip hold down reset button till it flash a couple of times and release.
It tried to restart by itself but just a very short "cold-start" sound for a couple of seconds. (Red LED light was up at the same time).
Then it went dead again and nowhere to be found, neither the designated IP address or the default 192.168.1.99.

connect a laptop directly to one of them after hard reset.  Then do the usual 192.168.1.99.
if using windows, make sure your networks settings are set to directly connect to miner

Does it connect?

[opentoe]

These C1's really need a new firmware. While other models have gotten many, this C1 has just gotten 2. His adverting speicifcations are not what is really happening in real life.

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?

Thanks for assistance. Solved.
It was some network problem, had some problem with the switchboard.
Fixed, back in business and running on an average of 47-49 degrees max. Need more cooling, trying to keep it 40 degrees max.

However, still having problem with 2 units where it started up running for about 2 hours then it just went off the radar.
Restarted a few times and still nowhere to be found. Still trying to resolve this.

When it goes offline or stop hashing, please see if you can log into the Web Control Panel.  If you could, please screenshot the Mining Status Page.

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 be 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 think 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.

Did you have to increase the voltage to get that hash rate? I had to increase all my voltages to about 0755 for it to get up to 1000TH/s. Stock voltage of 0725 only would top off at 950GH/sec. 0755 voltage increase my watts to 800 from 765, so I'm using a little more electric to get there. As I said before a more stable firmware needs to be written for this miner. Maybe it can run 1000+TH/sec on the default 0725 voltage that comes that way out of the box.

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.

This is why I have to baby sit my C1's everyday. Can't leave them alone for one day without me having to reset them or cold reset. Since the firmware doesn't tell you how watts are being used you have to put a kill-o-watt meter on it and constantly keep checking or you'll burn your power supply out and raise your electric bill much higher then you think. I'm still baffled how his rig can reach 1000+ watts  using mostly all defaults but don't leave your C1 attended for long periods of time without giving them a check.

Check hash rate.

Check for X's in status page. Almost ALL the time you'll end up with X's on the boards or hash marks all the way through. ------------. Why this happens, I'll never know. I've owned other miners from different companies and never ran into issues like this.

Check your temps.

Check the watts it is pulling from the wall. (this is your basic USA model, which is priced good and works well.)

I'm not complaining, just frustrated on how much time I spend on keeping three C1's running. All I have to compare them to are other manufacturer's and I never had to babysit my other ones.

I need to run @ 0760. Stock voltage on last firmware.

So you are probably pulling a little over 800 watts for only 1000TH/sec.

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.

@opentoe

Can you post the ebay link to the pump you are talking about?

also, any other items need to be purchased to use this pump?

Thank you!!

[dunand]

I run at 1.007TH/s on 2 miners with stock setting.

1.007 is the average speed since the last reboot. Yesterday my ISP cutted internet for an hour. Now my average is down to 1.004 on my 18 days uptime miner and 1.002 on my 10 days uptime miner. I'm sure this is not the first time internet is not working. This mean that that the miner real speed is surely higher than 1.007TH/s.

"Knock on Wood" My C1 & Syscooling pump has been running 2-months non stop. Sucks to see people having problems with theirs, I have hopes that a C2 will be made one day. The peace and quite really takes the edge off of my girl. With her not having to hear whirling fans at a high RPM, makes everyone happy.

I personally am not holding high hopes of a C2 being made.  You will see syscooling is selling a S5 kit already.  That makes me think there is a good chance C1 is last of it's line.

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
