Mark,
Your firmware doesn't support overclocking, correct? Any chance you'd consider adding it into your next version? I want to try your firmware, but I run my A2s at 1300MHz since the W/MH scale very well and my power is cheap enough.
What kind of performance/power usage are you seeing at 1300MHz? I'm seeing about 9.58W per MH on one of my units, and about 9.14W per MH on another unit. I don't have stock fans in my A2s, so my numbers may be a little different than others (the stock A2 fans are nearly 25 watts a piece, so I put in some more efficient fans). My A2s all have ~19/17W fans (12V/1.6A or even 12V/1.4A). May I ask what kind of fans you are using now? My 60mh was one of the first built, and had 2 really sub-par 25mm fans. I replaced those with Delta 38mm fans, which are 1.6A each going from memory. The 90mh unit came with 3 high quality 38mm 1.4a nidec fans, and those are still running strong after a year and a half or so. What is the highest clock speed available with the ANX firmware? Can someone share some screenshots of it? |

I've got a "60MH" and a "90MH" from their initial release way back when they cost $10000 a piece in April of 2014. At stock, they actually ran closer to 52MH/s and 86MH/s. At 1300MHz I get about 60MH/s @ 600w and 90MH/s at 900w at the wall running on 240v with Corsair AX860i PSUs in each. About 10w/MH all in. |

I'd also like to have an adjustable PSU efficiency option. I really don't think anyone is mining with such low (85%) efficency PSUs anyways! Personally I'm running 93.5%. Would be nice to have a box to adjust somewhere in the settings.

So, can sfards be considered a failure?

Hello everyone, GenTarkin and I thank you for your support. We wanted to update you on major changes that only affect the free users. Nothing will change for premium paid users. We have been looking over the free downloads VS. premium sales, and it is very unbalanced in favor of the free version. It appears that a high percent of people are using the free version, and we have only received a few donations, in short its being abused. Our intention with the free version, is to help those that could not afford the premium, and maybe they could donate a little over time. We want to further accelerate this project and fund it further and bring you even more exciting features. In order to do this , we are forced to close access to the free version indefinitely. We apologize and we hope you understand. If you see the value in the work we do, then please show us your support by purchasing premium on Ebay or my site (in our signatures).
How this will be rolled out: The github project is now private, the README on the github repo will still have all changes & features , it will be updated as GenTarkin continues to develop. This does not mean the project is closed source however. If anyone requires it, the source can be made available. Per release info will eventually be migrated to the public placeolder as well (old Titan public repo of mine).
Also, for ALL current users(paid & free) ... the UPGRADE button on status page will no longer function. It will be removed from future releases. Releases will continue to be distributed as .bin upgrade files.
Gentarkin and Vegas.
Welcome to my world with the Jupiter firmware, although you already went more "commercial" than I did and even a few paid users would beat what I brought in.. The most frustrating thing for me was not the passive commitment (e.g., using the free vs. paid) but the explicit promises made to donate by dozens of people I helped (remote logins, etc.) and never did.. I could have called them out of the forums but I didn't thinking they would correct things, sadly over 95% never did... Most miners on this forum are some pretty bottom of the barrel people. Bunch of greedy stingy fucks who want everything for free, and believe that everything is owed to them. |

You know, if Bitmain is going to sit on our orders for a week during their national holiday, the least they could do is give us a web cam in their data center so we can watch our S7's make money for them  A "convenient" burn-in test And let's not kid ourselves, we're being sold units that have been used by bitmain for AT LEAST 1 month. They know full well that some of their earliest built rigs had these issues. This isn't a last minute "oh shit" on their part as they were packing them up for shipment. They're playing dumb, and you've got to be pretty dumb yourself to believe anything they say when it comes to their fuck ups. They have a proven history of lying to their customers, and even screwing them intentionally. Voltage-gate with the S4 is a prime example. |

That 1500w comment from bitmain is total bullshit. I'm certain -droid-'s test tomorrow will prove that.
Maybe these sub par machines have lower quality chips? Perhaps a slight voltage bump would help some of the ones running on ATX PSUs which supply as close to 12v as possible? Most server PSUs including the ever popular 2880w and DPS2000 will put out 12.2v.
Has anyone with a sagging miner checked the output on their psu for any variance on the 12v rail with a multimeter? Does anyone have some that are working and others that are not to compare the rev on the hashing board? Ufo Would be nice if a few people could verify that. Please make sure you take the 12v reading on a PCI-e connector that is plugged to a blade and not an unused wire as there is a voltage drop that needs to be accounted for across the loaded wires. |

The issue was "request-diff": 8192. Removing it allows me to connect to your pool. Guess it's a bug with your stratum implementation, first time I run into this issue.

I can't get my Titan to connect to this pool. What am I missing? Other scrypt ASICs connect fine.
What settings and port you use? Titan's settings are: #skipcbcheck (also tried without this) "scrypt-n": 10, "failover-switch-delay": 30, "request-diff": 8192 I've tried both port 3333 and 4444 with a difficulty of 8192 specified. |

Wonder when bitmain will start shipping S7s again. My Sept. 2nd order still hasn't changed to shipped, and I just noticed that they removed the S7 from the sales page.

I think you mean to say: " XFX GPUs PSUs are made by Seasonic."
Indeed. My bad! I think you mean to say: " XFX GPUs PSUs are made by Seasonic."
Sure and i meant Any XFX things, especially GPU and PSU. The problem is not which sticker it has and which company actually did the assembly, the problem i've had with XFX is how random the components used seem to come from. So in term of individual performance in the same serie, one unit may work fine and the other not. Also for all Seasonic PSU, its either hit or miss. Some are very good, some are on the PSU banned/do not buy list. There's no hit or miss with Seasonic, they're all excellent PSUs. Where have you seen a "do not buy" list of Seasonic PSUs? They can have defects like anyone else, sure, but their power supplies are a known quality; always great. Companies that use or have used Seasonic as an OEM, such as Corsair, XFX, Antec, Cooler Master, and probably a few more don't have a say in terms of what components are used inside the PSU. They can specify the looks of the PSU, the wires + number of connectors, and the modular connector styles, but not much else. The bigger domain for PSU is on Overclock.net http://www.overclock.net/t/183810/faq-recommended-power-suppliesYou'll noticed the big XFX aren't on the list. There's a bad PSU list with quite a few seasonic on it, too. I don't see that bad PSU list anywhere? The fact that they don't have an XFX in the 1000-1700w list means nothing. They have the following Seasonic units iin the 1000-1700w bracket, and the XFX PSUs are the exact same thing minus the name and case: snip[/img] I'd suggest you spend some time reading reviews on jonnyguru, which is by far the most trusted PSU review site on the web. The reviews by OklahomaWolf are my favourites. You seemed to have missed what i said; Its branding, actual manufacture plants don't actually all belong to the same company manufacturing them. There are bad psu Series made from the same company and some manufactures batch will use cheaper part, this result in both bath series and bad batch. It even happen with Corsairs, so saying "Corsair or Seasonic only made good PSU" is inaccurate. This is hella offtopic, but we can go in another thread if you want. The only thing I'm arguing is that Seasonic does not make bad PSUs. I still don't know where you got that from. Seasonic doesn't vary their PSUs by batch, and quality is consistent. There aren't many actual manufacturers of quality PSUs on the shelves. EVGA, Corsair, and XFX have never actually made a PSU. They buy a PSU from a company like Seasonic that builds them, and then they put their names on it. I'm not sure what you're saying, really. Do you mean sometimes a crappy company like Thermaltake will switch OEMs down the line without changing a PSU's name, only it's internal components? Like starting off with a "TT 800W bla bla bla" made by Seasonic, and then in the future ditch Seasonic for a no name manufacturer with shit components? That can happen with companies like TT. |

I'm happy with these:  Done the job for 2 years straight! The corsair one is decent, its ridiculously overpriced but its in no way bad, at all. I would use it for sure if i had it, though i would never pay that much for a PSU that has lower end components than the G2, even though it has marginally better efficiency. At full load, it does not really have better efficiency. It doesn't handle overload as well as the EVGA's, you will not see such a tight ripple effect and as stable voltage(Though completely acceptable). And i honestly don't know how well it would handle 1300-1350W load from OC'ing the miner, while the EVGA G2 1300w will handle it. Still for the S7 run around normal clock, the corsair one is great.I wouldn't touch XFX hardware, PSU nor GPU. The Corsair is arguably better than the EVGA units quality wise, it's built by Flextronics. I agree about XFX and GPUs, but not PSUs. XFX GPUs PSUs are made by Seasonic. Doesn't get much better than Seasonic in the ATX PSU market. Top 3 manufacturers are pretty much Seasonic, Flextronics, and Super Flower. Super Flower is the OEM on the high end EVGA units. |

Phil, the included data cables are long enough to stick 2 or 3 of these to 1 controller? Can we get a picture of how the 2 of them look together?
I ordered custom cables I have a photo wait a minute here is a shot of my controller loaded for 6 boards. so: 1)full 2) full 3) full 4)full 5) blank 6)full 7) blank 8 )full 9) blank 2 custom long with 4 stock short this allows for 1 cat 5 not 2 and 1 unused controller snip this shows the long and the short cables. snip Thanks for the info and pics. May I ask where you ordered the cables from, or what they're called so I can search for them? |
