I opened today the last C1 package, and what a surprise. bitmain sent to me miner with the coolant and it had leaked out.

Repair leaks out, and it turned out that the pump does not work.

Now working one pump for the two miners and one miner still does not work, because I have not reached time to make a new wiring.

From 6 x C1 sets

1x bad micro sd (replaced)
1x leaky miner (repaired)
1x bad pump
2x bad wires

Sorry about wiring,here is the solution: http://youtu.be/WuuiWfjs9bY As for your pump,could you please send us an email ([email protected]) ,we need to know further information about the pump.

As a point of reference, I have two C1s up and running for ~4.5 days. Both are stable at stock. GUI on one is 1005GH/s the other 973GH/s (one bad chip on this one); Pool reports 1.03TH/s ( Huh

) and 949GH/s respectively.

Try setting your voltage to .735. should fix the "bad" chip

Thank you...worked like a charm. At re-boot (first in 5+ days) the case fan is spinning slower/quieter, too....no idea why. I will report on stability in a day or so. [NOTE: Actual voltage value in advanced tab is 0735]

Does C1 has an option for wifi (like S3 does).

Has anyone explored this yet?

The C1 uses a cost-reduced Beaglebone Black as the controller, there is no wireless radio.

Concur. Bitmain suggests creating a wifi bridge using a second wifi router as a client for your main router. I can't figure out how to do this and maintain an acceptable level of security for other devices on my network, so I fell back to hardwire. I imagine it is possible to create such a bridge, I just don't know enough about networking to do so comfortably.

I really don't know why BitMain moved away from the the controller board they used in the S1 and S3 (well I guess I do...the answer is cost). This is unfortunate; wifi is/was a great option for me. I never had an issue with decreased speed, reliability or anything else. And wifi made it super easy to move miners around the house (e.g. out of a guest bedroom if we had guests, etc).

Bitmain, maybe you could offer the older controller board as an option for a few bucks more?

Are you saying coolant was inside the miner? Or they sent like a supply of coolant?

So just to clarify (this is my first time hooking one of these up and I don't want to Fry it.), I can plug into each one of the two 6 pin power connectors each from a different PSU?

1psu / blade only! do not power 1blade with more than 1psu!
blade=board

Can 2 power source units be plugged into one card?

One miner, yes, one PCB, no.

I have two and winter air for cooling. One is hitting 1050 and 1030. Had problem with bad sd on one. But once flashed with good it works great.

Used rm-1000 on both. Working great.

Love RM1000s, I've got 3 now. 16AWG, 8 PCI-E, 1KW (likely 1.1+), has no problems with 40-50C ambient.

URL：http://youtu.be/WuuiWfjs9bY. For your time and effort we are very sorry about that,we have tried our best to solve the issue.The problem is the terminal and wire are easily separated,so the harness will not work.That can not damage your C1 boards,if your board is fried,there must be other problems.You could email us,and we will help you as much as we can.

This is what happened on my two cables, hence its now getting fixed. Instead of soldering I bought some more PCB crimp connectors and remade the end.

It can be run without Miner C1 start not water cooler?

No, must have watercooling

Yup... I got boned really hard by that (not because of the repost, I ordered them previously so I could get up and going the day they got delivered) ...

I'm not sure if I was more upset about the $50 I'll never see again (figured it out after opening them) or the fact that I don't have any quick disconnects on my miner.

Shakes fist angrily at whomever made that post in the first place.. (jk dogie, shit happens life goes on. )

I cried myself to sleep, but then I remembered there isn't any crying allowed in bitcoin mining.. Grin

could you imagine? Cheesy

Yeah my bad, the original specs were going to use 6mm ID but it changed on release [and I didn't recheck]. I too have a set of quick disconnects I cant use, but they're more like $120 worth.

.Here is the solution (http://youtu.be/WuuiWfjs9bY).Appologize again...

Syscooling.com,

REALLY? Huh

?? First, the link to the youtube video is incorrect, so I have no idea if your "fix" actually works or not. Second, while your apology is appreciated, you offer nothing for the time and effort I needed to invest to get the miner running despite your failure. Third, your cooling system damaged one of my C1 boards, but you offer no compensation for that either.

All,

As and FYI...I ordered a few PWM (1x 4Pin to 2x 4 Pin) splitters that I will use to replace the syscooling.com harness. Each miner will need two splitters (I plan to plug each into a the fan header on an available mining board and run through the top openings rather than the front fan wiring cutout as the original instructions suggest). I bought ten units for USD 1.85 each (they are even cheaper in larger quantities). They are available on ebay, aliexpress, amazon, etc, etc. I will report on back on my experience once I make the mod.
