new firmware update posted today one of the changes is increased voltage to 760 This is the fix you all are looking for so I suggest anyone with flaky performance on there C1's do this update. I pushed my voltage up to match the new update and my miner is running even better then it was a 745 volts
I don't get it. I flashed the new firmware and my voltage is still the same as it was before I flashed it. I had mine at 0736. Am I supposed to change it manually to 0740 now or something? Did you shut off the power on the PSU and then turn it back after you completed the flash? Yes, I power cycled the units after the flash. Why is this 760 voltage important, couldn't the last firmware you enter 760 as well and reboot it? I also think I checked "save settings" so maybe that was it, but my original question remains. Was the old firmware not compatible with 760 or something or had a maximum? |

That SP20 is a cute little rig. How many BTC is it making a day ?
You already know the answer to that question. twenty five cents a day by Easter more likely 2 dollars a day by April 15th, but your 25 cent estimate is possible. Philipma1957, where are you hosting your SP20's? |

My all 6 C1 is 250M 0725 Lack of information. On the original firmware you could change your voltage to 0760 also. What makes this voltage so different? |

I'm using my Corsair, not the harness at all on all three of my rigs.

Those Sp20's in an isolated room or away from family living? Just cause of the noise. They are not loud if you downclock. I would say medium vs loud. At 70 and 80 settings they are loud. My fan is set to 40 on the one I have. my sp20 uses only 730 watts and 1300gh this is about 0.56 watts they are also in the attached garage so sound isolates from my living area. I am trying to find the lowest settings I can do on this machine. Reminds me a lot of running GPU's back in the day. Underclock saved a ton of power and heat. I have an attached garage too, but I keep my car in it. Only a single car garage. Winter time is nice for running gear in there, but when it gets hot, the garage gets over 100 degrees so that's not even an option. I have C1's spread all over right now doing a pretty good job of keeping my heat off for now. Just issues with one. Add them up and my SP10, around 5.5TH/s. |

I'm still having issues with getting one of my miners to 1000TH/s. I've increased the voltage, added in three pools as Bitmain requested and this unit just doesn't want to hash where it is supposed to.
Also, anyone notice pressure build up in the loop? I wanted to check my coolant level, so I unscrewed the fill cap and it was like opening a can of soda. I know some pressure is caused by the heat, but these loops aren't made to handle the pressure, right....certainly not the pump.

Thanks, nice utility. I have a quick question. It found both my C1's fine. I named them, click save and then went to the AntOutput page and it is grabbing data already but I never put in a password in the config area. I did change the PW to a different one. How is the program accessing the C1's without a password? I only changed the WebUI password, I left the SSH password default. Is that how it is getting the data?
I think the default is
user - root
pw - admin

What's up with the three pools in the miner configuration area? All of the other miners I've had only had one primary pool, then it had backup pools in case the primary one failed. Is that the way this is setup here? Since I can't consistently hit 1000GH/s on 6 C1's I had Bitmain ask me to fill out all three pools. What's the theory behind doing that? If the pool is down, no hashing. Pool is up, hashing. Right? Unless I'm missing something here.

I can't help but wonder, the folks with the burnt out pumps, is the pump intake coming from the radiator (hence cool) or the C1 (hence warm/hot)?

I can verify my two were not temperature. It was cold ambient being used from winter winds. I wont go into my story again, as I'm sure your all bored of it. But still over 3 weeks no RMA from syscooling. Are you still using that tall pump you got off Ebay? The one for $38? How is that working? |

So no one is going to comment on the several users having X's in their ASIC status area and having under powered units?
Several users being you, and one other person who fixed his. What exactly do you want people to do about it? Chinesesavoir and Mindtrip both had X's in their ASIC status area. And when you have those X's your (guaranteed) hashing power drops. And after changing the voltage, which I've already done to 740, the X goes away but eventually comes back. Now with 2 X's for even less hashing power. What if I wanted to sell in the future and as the specifications indicate 10008GH/s and the unit can't even get to that, then I'm pretty much screwed. I'm just wondering how every is getting 1000TH/s with no problems and I have 6 of them struggling to keep above 950GH/s. I guess I'm just expecting more support and attention like I'm use to with other companies I have purchased from. Are you here as a mascot/cheerleader for Bitmaintech or really here for support purposes? Opentoe - Bitmain has a support system. I'm in the US and have had a bad S3+ board swapped by their folks in Denver. Their system worked perfectly. This thread is not their warranty system, so posting here is not the most effective way to contact Bitmain support. I have been in contact with him for over 2 weeks now. He repeatedly asks me the same questions and has asked me what my order number was three times. Maybe he's real busy, but really could use some help in the support area. The response times are slow and quick worded. Usually it is 3-4 days before I'll hear from him next. I keep hearing about this support place in Denver. Multiple times. How do I contact them? |

Not sure what is correct, but I just used basic common sense in hooking it up since the picture on the paper was different than what was in the video. I have the output side of the pump going into the miner (doesn't matter what side) and then back out into the bottom radiator port. Could be the top, doesn't matter. Then of course the other radiator barb going back into the high side up the pump with that tiny little reservoir. I ended up buying a $50 pump from frozenCPU. The guys at frozen said it would give me much better performance, not put any additional pressure on the system but get a better flow and if I wasn't happy could return it for my money back. Hey, whatever works better and to get my 1000TH/s which I barely see. |

Are you here as a mascot/cheerleader for Bitmaintech or really here for support purposes? So here is an update I was only able to perform the volt mod on 1 unit as the other is in my office and I won't have access to physically power cycle it until monday but it appears over volting the one i have access to has eliminated the X issue after 12 hours of solid run time and I am now running over the guaranteed hash rate. I will test the other unit again in the next few days with the same voltage and see if this is a good fix for the issue. You have to remember from the factory these are overclocked from what and S3+ is running 225 vs 250 so there is a good chance they need slightly higher voltage to maintain that overclock for long run times. I have spent time reading through the spec sheet on the chips and I suspect a 10 to 20 step over volt will not do any harm to the chips long term and will help any users with random X errors. I hope this helps those members with the issue I thought you needed to power cycle it to change the voltage. Unless you SSH'ed into it and ran 'reboot'? I had voltage at 740 and I had three X's. So I dropped it back down to 725. What is the max voltage to use here? Since these are already being pushed to the limit there isn't much room to do anything. When you push something to the limit that's where the random behavior and negative results happen. I have been in contact with Bitmain over email, but it is like 3-4 days for each response, so if we are trying to troubleshoot something it can literally take a month. |

Me and old pop (My Dad) bought a few Bitmain C1's water cooled rigs. Within the setup of that rig there are three sections you can setup three pools. I'll put my primary pool down, and then I'll input BTCGuild as the secondary but the Guild keeps telling me the worker is offline. I'm getting feedback from Bitmain that all three pools should be connecting. Yes, confused I am again, but how do you control how much hashing power goes to what pool, and is there a way to kick start BTCGuild?
I'm using
stratum+tcp://stratum.btcguild.com:3333
and then my worker name which is correct.

These were originally Mercury's but were upgraded with new modules. They each run stable and consistent at 550-560GH/s and pull around I think around 750watts. It has been so long I checked, that could be off 50 watts either way. Both have been taken care of, cleaned daily and not modified whatsoever. If you are interested, please let me know. I am in NJ, so a pickup would be very easy since it is a pain to ship something like this. Thanks, Michael   |

I got 2 Units on wednesday both seem to be underperforming from there guaranteed spec at stock clock and voltage. One will not take a single step overclock without throwing X I am going to spend some time tinering with voltage and clock speeds anyone have any feed back on voltage steps other than to go in steps of 10?
Yea, well this seems to be a problem here. Between me and my father we own 6 C1's and all of them have X's under the ASIC status area and ALL are underperforming. Apparently other users are having the same issue. If raising the voltage doesn't resolve the issue what are we supposed to do? Get an RMA and ship all these back to China? I think Bitmain needs to modify the hashing speed on these C1's. More like 950GH/s. I haven't seen 1000GH/s in a long time. Is there a support channel through the Bitmain site or something? |

What is the max voltage you can enter without damaging the C1?
Apparently I'm not able to sustain 1TH/s as guaranteed. If something is sold on the basis of that guarantee and it doesn't meet that guarantee, what's are options?
