I have heard the Corsair CS650 switches off because of excess voltage on the 5v, when 12v rail is fully used. Is there any way to prevent this - what device could be hooked up to the 5v line?
Also, is the Coolermaster Thunder 500W any good for an S1?
Thanks
I'll say no to the CM T without even looking at it, it takes a really high end PSU to run 24/7 to 100% loading like we ask of for bitcoin mining. Spend a tiny bit more and save yourself the hassle. I hadn't heard that about the CS650 and I'm not sure how that would electrically happen. Do you have a link? |

It looks OK to me (is your monitor calibrated?) and I decided to set it this way so that it's consistent with other colors that are mentioned there, but if there are more people having problems reading it then it might be a good idea to change it.
Colour calibrated Dell 2407 FPW here and it still looks weird, I think generally yellows don't work great online. |

I think the gap is too big between senior, hero, and legendary. 6 months at least. I think there should be some more ranks to diversify things a bit.
why? Ranks have a certain consistent scheme. 15 --> 30 --> 60 --> 120 --> 240 --> 480 --> ~960 It is no accident, that they made it the way it is now! It doesn't make sense though, because that final jump is literally 14 months, well 9-16 months. And then during the additional 9-16 months, it will increase with inflation to keep the numbers down. In 14 months, if every other account on the forum was active, they'd all have become hero - that's how long that final jump is. Not even considering that activity is still limited in that its a time based metric. |

I can buy 2x 750s to run 3x AntMiners, or for the same money or less, buy 3x 500s to run 3x AntMiners.
I've read the awesome PSU comparison, of course thing are always changing. I'm leaning to continuing with what I have, a single 500w power supply for each miner. Looks good, easy resale as a package, currently not paying for electricity (2-3 months free).
Leaning to Corsair CX500M units. Considering Corsair CX500 units. What are alternatives? Gotta be safe! Are the Sentey units any good? For the equivalent of a Corsair 500 I can pickup a Sentey 600-700+ watt unit.
Thanks Dogie... really appreciate you sharing your time and expertise.
and... what is *the* mining hardware out there or coming up? looking to partner with a friend on a serious miner, rack mountable and multi TH/s. what's coming up?
CX750Ms any day, it adds flexibility later and has way, way more PCI-E cables which you need. |

So it looks like you only need to connect one set of PCIe connectors to mine then? Is there an instance where all 8 would be needed?
Unless the specs have changed, I believe they can be overclocked. I'm assuming they probably get hot on higher clock settings so you would need good airflow At stock its 220 or so W per PCI-E, OC'ed (which they do amazingly well) you're looking at 250W. Both those numbers are pushing* it for a single PCI-E cable, and its definitely a nono trying to power two miner boards from one non high gauge cable branch. *I know we did it for the S1s, but this is starting out way past even the top end of S1s. |

Anyone (FC/bitquan/dogie/CanaryInTheMine ) making a video showing the box-to-boot from parts for the AM Tube ? As the saying goes: 'a picture is worth one thousand words'; a video could help show the relationship (and quantity) of components and the 'beauty' of the design and so help some buyers estimate the assembly cost/time.
The assembly could include references to the handy tools and extras (thermal paste? non slip pads/tape for the front/back panels, screws, fan grill for the pretty version?, typical PSU) that could or would be needed but are not for sold by AM as part of the package.
Yeah I could probably do that now, just tear down this unit. Its as simple as can be to assemble, normal flathead screwdriver will do almost everything unless something changes. Might be better waiting for the 'retail' kit though so I know exactly what is being included. oh my, retail kit... looks like FC has taken the road of customizing and diy fun miners for large public. Such move. As a cat, really. ^^ In reality these sales are for the resellers, actual units will make their way to the public fully assembled. Anyone wanting to buy in bulk can still save a bit and buy direct though. |

What is the temp range the BE200's are running at on the rig you have?
Trends
Hard to say exactly as there are no on die temp probes, but from the pcb temp probes on other BE200 units, hot. And from the exhaust temps of the air, very, very hot. There should probably be a warning sticker on the end away from the fan not to touch the units as they're too hot to touch (including the aluminium stand) when running. |

I think the be200 chip is 40nm.
Anybody know what the be300 chip will be?
28nm, 20nm...
Good  |

Refunds are significantly delayed and they have used stall tactics. You act insulted when people question your ratings, but you choose to ignore these serious problems. I was supposed to be refunded 3 months ago. It's really significant actually. And they use stall tactics.
You are not helping the little guys when you ignore this stuff. Some of us can't afford to lose that money, and if you rate them as 'fine' they have no real reason to pay us back.
"1 - refunds significantly delayed or not being processed at all. Includes stall tactics." is the truth
Then how do I differentiate between people who are refunding partially, and those who aren't at all? Goes back to I can't have all moderately bad companies with the worst possible rating because then you don't have any scale. For the 800th time, I am not 'ignoring this stuff'. Its simply impossible to integrate the opinions of 1000s of people into one rating, when most of the opinions are biased due to having orders gone wrong or propose unworkable solutions. If you really think you have a better idea and I'm 'ignoring you', go make your own thread. |

The unit I have hashing in 24C ambient is at 91 and 93C per chip, previously was 99 and 97 per chip, and when the unit was moved to our warmer facility shutdown due to thermal throttle
I don't think thats thermal throttle - of the CPUs anyway. I put my unit in a 40C cell and the chips were at 90C, and they've told me they have their software cap at 110C. The ASICs internally throttle to keep the temps below that. Either way, you might have some dodgy mounting of your blocks? |

Should help people out- I was following your guide till I hit that part  Done. Have you got one of the flow altered units or one of the 'older' units like me? Mine pulls the air in from the top, and exhausts out the front/back, weird setup. I think im going to flip the fans around and check the temps. I wouldn't do that, its specifically done like that for board airflow. I thought maybe you had one of the revisions. The pull setup does not put any air over the boards, just pulls in air from the top and pushes it out the side vent, and the front/back vents, maybe if anything the top board gets a little airflow. I did end up swapping them, and saw a 4-5C reduction in temps per chip, I will do more testing. Its not the chips which are the problem though, it gets a little 'unknown' at this point. Chips only throttle at 110C so they're no where near their cap. |

Great write up again Dogie, thanks. I was curious about this unit when I saw all the ads popping everywhere.
I find it interesting that it uses watercooling, I would think that aircooling would have been the mode of choice to bring the price down and made it more price competitive... It has no rackmounting either, kind of a bummer. I see these sitting on an enthusiasts desk somewhere though.
The units are much smaller than typical racks. You can 'rack mount' them by putting a shelf in and stacking 4 of them up though. |

As a heads up, the default IP is not 192.168.0.xx on all machines, our machine and the user manual states that the default is 192.168.1.140
I know, it changes on every machine. I have to refer to something for the sake of the instructions though. Find the configuration sheet included with your miner. This will include the default IP of the miner, the subnet of the miner and the gateway of the miner. It is assumed to be 0, and the IP and 192.168.0.80 and the gateway 192.168.0.100 - adjust as appropriate. Not according to them- all the machines from now on will be set to 192.168.1.140 per my conversation with them and http://www.bitcrane.com/down/T-110en.pdf , and none of my boxes had come with any config sheet in the box, just the miner and power cord Ok, I'll change it. |

Does this have inboard cobtroller software?
If you read the thread, there is a tiny controller board that daisy chains up to 32 mining boards (8 miners). Do the hardware manufacturers even realize what the bitcoin difficulty is lately? We need asic miners that perform in the > 4th/s range at this point.
Go design one then. |

SCRYPT-N/X11 - more ASIC resistant, still being mined with GPU's but in the end may become ASIC-ified if there is enough momentum/value in it.
By the way it is rumored that manufacturers already has a samples of X11 ASICs since May. On trader from Russla told it. Yeah. ASIC resilient is a misnomer. I can make my own encryption protocol and go 'look no ASICs you can't build ASICs for it'. It doesn't matter if I spent 2 minutes or 2 years researching that protocol, you CAN build ASICs for it by the very definition of an ASIC. |
