Download this program and use it to "flash" the SD card with the image file.

You can't just copy the contents.

Anyone able to tell me how to flash an image?

just copying to the card does not work

I couldn't run the unit for longer then a couple of minutes because 2 of my fans were not working. Picture provided above as well. Why the heck they tried to put two fans on one connector baffles my mind when their harness clearly has three fan connections. So I put a high speed table fan in front of the radiator to make sure nothing would over heat. The unit only powered and worked once. After that it just ran the high speed fan initialization process and that's it. Would not even connect to network or get an IP. To make a long story short I had to flash my own SD card for the unit to boot up properly. After several boots, I tried the original SD card (flashed) and it wouldn't work. Apparently a defective SD card. As long as the miner works I'm good with that, but not having two fans working is making things a pain in the ass. I really don't want to trust a table top fan to cool the loop. Since the fans come from syscooling, I'm dreading trying to work with them in getting replacement fans since I saw one guy on here wait for many weeks to get two pumps replaced. So in 20/20 hindsight, the unit wasn't DOA but whatever killed that original SD card is unknown to me.

I downloaded a flash image called C1 Image - DHCP.zip at https://mega.co.nz/#!tEIQkDqJ!wTLk4B_K2IiNl248puBU6JXsq5hF7nR1wzWPJqvKHT0 from the 2nd post from Dogie. If this was why his information was in the pools then I apologize for being so brazen about it, but at the time (2am in the morning) I was just tired and pissed about shit not working.

The unit was not DOA based on the photo you provide. It clearly operated at spec for over 3min, with the default pools being part of the installed firmware. You re-flashed it with a different firmware and now it is half-working.

Yes, this morning I just noticed all three brackets on one of the fans is broken. Who is receiving fans with one 3 pin connector attached to 2 fans? I agree with your statement about Dogie and all the other statements I've just read about him.

Thanks. After spending more time with it last night it turned out to be a physically bad/defective SD card. I had to use one from my camera to get the unit to boot up properly. Since I don't have any extra fans for my radiator I really can't run the unit until I do. There are no stores around here at all that would have fans like these, and from the feedback I read on here trying to get an RMA for defective parts is almost impossible. I really wish I knew that before I bought these things.

Are the brackets for the 2nd fan in that pic broken?

Just ignore dogie's response and try to get someone from bitmain direct to answer you. ie someone who can give you a real answer. replying to dogie's responses will get you no where.

Agreed, bitmain have lost their way. Employing people like dogie make it worse since all they can do is tell you to RMA or wait for them to find out a solution to your problem. In the mean time you are losing each day the miner is offline. The best offering is by far the spondoolies sp20. Dogie tries to talk it down since he isn't employed by them, so just ignore his comments. But if you check out the recent threads, like philipma's, he and many others are loving them for their underclocking and therefore long life expectancy due to the low power they use when underclocked. Don't take my word or nodogie's check the threads by others.

You just posted a screenshot of it running @ 1TH, how is that DOA?



There is information EVERYWHERE about that, in the #2 post, in the Bitmain guide, in my guide. You can use the reset button or reflash the SD card using the image in #2 post.



That's just the defaults on the image I made in post #2 [so we know they work]. It does not mean its used, unless I have been cloned in China. tldr, its not preowned.



That's systech and I doubt they manually require fans when they already make the harness.

8mm ID, ~10mm OD.

There is a hard reset button next to the Ethernet port.
Be careful as the button may not line up with the small hole perfectly

Reset Procedure:
Power on the C1 and let it run for 3-4 minutes.  

Press and hold the reset button with a paperclip for 5-10 seconds.

Let it go and wait for 3 minutes.

Power it off and wait for 1 minute

Power it back on.  

It should be 192.168.1.99 and clear all the setting by then

Unfortunately Bitmain's S1 days are gone.  They no longer make rock solid items.

I may get one more C1 (or C2?) one day if the price is low enough, just to have more water cooled gear for backup purposes.  Otherwise it seems Bitmain has lost their way and it's unlikely they'll be getting anymore of my business.

Received a DOA unit today. All it does is stay at that high pitched fan noise and doesn't connect to the network. I'd love to troubleshoot, but the lack of information is holding me back. Can I manually flash the firmware some how without accessing the unit via IP? Is there a hard reset button somewhere?

There is a serious problem here. I re-flash my rig back to defaults and now it is only hashing at 500GH/s. Also, Dogie's name was all over it. I have a feeling maybe someone knew it was bad hardware and someone didn't want it, so they shipped it out anyway.

Why can't these fucking things just work? I'm really starting to hate myself for trying to save a little money when I could of had a Spondoolie that could run an entire year without intervention. These things are like kids. They need constant attention and work just to get them running normal. Looks like I'm definitely going to RMA this paperweight back.

These were the pool settings that were in the rig before I had a chance to even flash it. So to top it off, it seems like it was a used piece of hardware also. And I could only wish to get that hash rate. Won't budge over 500.





And more bullshit. Since when did they start combining two fans into one connector??? Well, they fucked it up. Now both fans don't work. If you look closely you'll see that two fans are connected together using the same 3pin connector. Well, guess what? It doesn't work!!!! They either have a bad crimp or another crossed wire or just have no idea what their doing. That shit is going back to China and I sure as hell hope I get an UN-USED unit with proper wiring.

I have two of the ebay pumps.  Both good quality and running great they are rated just a little faster then original pumps. Also much larger reservoir and different design.  I also purchased the 3 pin molex powered board that's powering them.    The main reason of that pump was it was shipped quickly in US and I needed a pump quickly(as both original pumps died and syscooling RMA I won't go into and waste more space).

What water pump do you have there in that picture? Is that the one from Ebay? How is the quality? I purchased one from FrozenCPU for $100, yes, $100 but the quality was excellent and turn around time would be quick. Not sure what to do. I just want to mine my 6 rigs at 1000TH/s that supposed to be guaranteed. according to the sales pitch online.

When my voltage was on 725, watts at the wall was 745-750. I increased voltage to 760 and the watts at the wall went up to over 820. So be careful when making changes to the voltages. Unfortunately I have a bum unit where it just won't get to 1000TH/s unless it is at 760 volts, but I have a feeling if I keep it at 800 volts it's gonna burn up real quick.

My question still stands. What does this second firmware do? Changelog, anything, please?

what size is the tubing on the c1?

While mining is a lot easier than it was in the GPU days, it's still rough.  If you don't have parts laying around, it's hard to troubleshoot things.  If I were in your boat, I'd try another PSU on the C1 and see if it works.  If it does, then your PSU is at fault.  If not, I'd reach out to Bitmain ASAP to troubleshoot it and/or replace it.

Also, I'll echo what someone else here said, I'd avoid Thermaltake PSUs.  Next time you're looking for a PSU, get a EVGA, Corsair, or Rosewill Lightning.

Are you in the US?  If so I'll take the U3s off of your hands, just for experimental/development purposes only.  (Yes, they run hot.  Very hot.)

Thanks,
 I am still trying.  If I leave it plugged in for over 20 min finally all of the little red lights come on the hashing boards. At that time it shows it is taking 350 watts at the wall and is giving off heat

When I try to hook to 192.168.1.99 it requests a pass word.  I have tried root/root  admin/root root/admin admin/admin and so on.  No luck,  I am going to go buy a sd card and try that I suppose I should try the new firmware  one.

It is just frustrating, I have a S3+ worked out of the box, I have a S4, would not work after some research Took out the sd card then put it back.  Runs fine

The S4 is too noisy for where I have it, so I came up with the hair brain idea to test drive a C1 if the first one passed the quiet test, I was going to buy 4 more.

Most frustration I bought 2 U3's, and well they are still in a drawer and will remain since I almost burnt the house down

Let me also say I am retired and no not expect to get my money back, the money in the bank is a loosing thing at 1% interest and 2% inflation.  This way I can accumulate BIT and hope when my grandkids are older they will have some BIT to play with.

I wish Bitmain had better quality control
