WTF??? I got an "Export Scan," but now, the same message is back??? Could this be U.S. customs? Also, the times are off. How can 10:58 a.m. come after 8:34 P.M. on the same day? I'm assuming this is local time, so maybe that means it made it to Alaska???

Basically, KNC fucked a lot of people over with Neptunes and Titans. Every Titan that is shipped out seems to have at least one cube with issues out of four cubes. It's a complete mess. It only works properly on certain pools, multipools are pretty much non-functional. Each Neptune/Titan cube cube should have two PCI-e connectors, but only have one. No Titan shipped will ever ROI, I paid mine $10k and I'll be lucky to make half of it back.
Only thing it has going for it is it's very low power consumption per MH/s.

Why can't I solo mine viacoin? viacoinqt refuses to allow miners to connect.
My viacoin.conf:
daemon=1
server=1
rpcuser=prelude
rpcpassword=x
rpcconnect=127.0.0.1
rpcallowip=192.168.1.193
port=5223
rpcport=5222
I've got plenty of experience solo mining, and all other coins work. Just can't get via going for some reason, what am I missing?

Hard to believe that only this late in the game are manufacturers catching up to innosilicon's efficiency. I received 150mh/s worth of A2 machines in May, 10w/MH/s at the wall.
KNC (lol) are the only ones to have beaten innosilicon at the scrypt efficiency game. My Titanic with 2 dead dies is pulling 310 MH/s at 4.3w/MH/s at the wall.
not sure what you mean but I also own an A2 and it's : 23.53 watts per MH your titanic is using: 13.87 watts per MH The MAT machine is a little over 9 watts / MH The MAT machine is the most efficient scrypt miner I know of on the market.  You're wrong. Which A2 do you own? At 23.53w it sounds like you have a Zeus miner. 1st batch 60MH/s: 610w @ wall, 63MH/s: 9.68W/MH/s @ wall (240v with Corsair 860 AXi) 2nd batch 90MH/s: 920w @ wall, 95.5MH/s: 9.63W/MH/s @ wall (240v with Corsair 860 AXi) Titanic 310MH/s: 1290w @ wall, 310MH/s: 4.16W/MH/s @ wall (240v with Delta DPS-2000) I just checked all 3 with a Kill-a-watt. |

I'm currently buying S1 Bitmain Antminers for .12 BTC each. If you have some to sell, send me a message on here or at convicted2008@gmail.comHow many are you after? I might we willing to sell 20-30 of them currently. Where do you ship from? I might be interested in a few. |

what... I wish I was a MIT student.. wtf..
You wish you were an MIT student so you could get $100 for free? Seriously? |

Anyway to add the S4 to work with this?
Add it as an S3. Works for me, mostly. |

Gotta hate when things get stuck in customs, especially time critical stuff like mining gear. You're at their mercy, unfortunately. I'd say dogie is right, shouldn't take more then 3 days. Less if you're lucky.

Maybe, maybe not. A lot of places in the world suffer from brownouts which can bring voltage plummeting down to ~90v. For anywhere in Canada/USA to be a constant 100v instead of 120v to me is ridiculous. Detroit is a special situation though, I suppose.
I'm fortunate enough to have one of the best electrical utility companies in the world (Hydro Quebec) servicing me, so I don't have to worry about low voltage situations. I draw a constant ~100-120A from my 200A home electrical installation, and still show 118v/236v at the wall. That being said, I would gladly pay an extra $20 per miner if it meant having an actual quality PSU in the unit. When it comes down to it, these high wattage power supplies almost have enough current to arc weld. I have absolutely no faith in a no-name Chinese power supply company, and my worries were proven right with the S4. I don't care if it's made in China, as long as it caries a known brand name with specs and reputation that I can look up. I'll pay extra every day if it means getting a hassle free PSU from the likes of Seasonic, Flextronics, Delta, Super Flower, etc. Apluspower Co. doesn't inspire any faith at all, and is a fire hazard in my books.
I'd like to believe that the revised power supplies from B2 will solve the issue, but there have already been reports of burnt out/DOA PSUs. I'll be replacing mine with 2000w Deltas to be safe, and when I sell them they will still have working OEM PSUs.
Its worth noting that there is nothing wrong with those B1 PSUs for computer use - the problem was caused by the unusual loading pattern miners have. This turned would would be considered sensible cost saving [/earlier development] into a failure mode. Unusual pattern or not, if it was a quality unit it would have handled the loads. There was a lack of engineering somewhere along the line at Apluspower Co. that resulted in them failing where a proper PSU would not have failed. The day my S4's PSU died, I ordered a replacement Delta DPS-2000 for it and also for my newer B2 S4. I know the Delta unit will handle the loading pattern without issue, as any well built PSU should. I would expect consumer grade PSUs to handle the load also, so long as they are quality units from Seasonic, Felx, etc. To be clear, I'm not bashing Bitmain. They are not power supply manufacturers, and I'm sure they took A+ at their word that their PSU's would be sufficient to properly power the S4. A+ is to blame here, IMO. I bought my DPS-2000 for $30 on ebay. If I'm not mistaken, they were introduced on the server market about 5 years ago and cost somewhere in the 4 digits range. While it's used, and requires cooling be provided externally, it's a much safer bet than anything A+ could ever muster. Maybe in the future Bitmain would be better off integrating an unconventional used server PSU in their units. It doesn't get any better than a server PSU from the likes of Delta, Zippy, etc. Even when used. |

As for US residential powerlines... this should be a major design concern for Bitmain or any other miner mfgr because PSU's do NOT like low lines... In Detroit area home power is 110v - not 120 - and during summer will often drop to 100-105v. The '220v' incoming reflects the same drops. This year it got so bad (hit 95v for 2 weeks) I had to wire in a boost transformer to make up the difference...
I'm not sure anything can be done for that. The vast majority of the market doesn't have that problem, and one which will affect all electronics. 'All electronics' - and more. Gas clothes dryers and stoves did not want to work either because the igniters would not come up to temp... In this instance the problem only really affects PSU's being pushed to near max output. What to be done? Easy answer, appropriately de-rate the PSUs like HP did with their CS server PSU's so it can run on a low line and still produce required power. Then it is just a matter of balancing cost/benefit. Frankly, given how vocal folks can be here when there is an issue I'd err on making sure they can go down to at least 100v to cover wiring in old homes & apartments. 1400w miners aren't designed for old homes and apartments, and its not fair to make every customer pay another $20 a unit for that small minority. Frankly I'm surprised your derating problem is even legal in the US. Maybe, maybe not. A lot of places in the world suffer from brownouts which can bring voltage plummeting down to ~90v. For anywhere in Canada/USA to be a constant 100v instead of 120v to me is ridiculous. Detroit is a special situation though, I suppose.

Btw, does anyone know if the new update allows you to mine on eligius now?
I'm testing eligius with 1 S4 right now, it assigned 2048 diff shares pretty quickly, looking good so far. I;ll post back with stats soon. Any other pools anyone wants tested while I'm at it?
Works perfectly with ck's custom cgminer. Haven't tried with the stock cgminer that comes with the new FW update.  |

Well I decided to try and test p2pool with my KNC Titan.
Not surprised to see it fail horribly.
10 sec share is like fast coins and the Titan flushwork issue just causes constant rejects and "Dead on arrival" shares.
32 found shares 25 DOA
I have setup p2pool for bitcoin and has worked well so I don't think my setup of the litecoin node is the issue.
Thanks for posting that. I was thinking about setting up p2pool for my Titan, guess I won't bother. |

Thanks for that, I did wonder if you'd used the zero setting for queue.....expiry & scan time are pretty obsolete now though.
No problem! I'm pretty new to p2pool, and I stumbled across those settings somewhere. So I shouldn't bother setting expiry and scan-time?

I've been mining with p2pool lately and it's working perfectly.
Would you mind sharing the miner settings you're using with p2pool? Also, what is your reject/doa rate with the S4 & p2pool? Thanks.  That's with 2 S4s running. Latest firmware installed (10-16) with ck's custom cgminer, each running at 225MHz. I edited cgminer.sh, changing queue from 8192 to 0, and added expiry 1 and scan-time 1. Share difficulty manually set to 2048. |

It's a shame there were so many S4's out with problems.
Mine came in, I manually set difficulty, increased the frequency and consistently hash at 2.3TH no problem and no complaints.
Same here with my B2. My B1's PSU died, but it was replaced quickly. All in all I'm a fan of the S4s. CK's updated cgminer helped a lot too. You are a fan of a miner that won't let you choose what pool you want to use? I use eligius exclusively and I didn't read ANYWHERE on BITMAINTECH.com that the S4 would be exclusive to pools that allowed you to set minimum difficulty. So to me, even IF I could get my S4 working, it would still be worthless, because I can't use the pool that I choose. Why am I the only one who finds this outrageous? I can mine pretty much anywhere with them since I updated to the latest firmware + installed Ck's custom S4 cgminer build. I haven't tested eligius for a while, and while it didn't work earlier I'm confident it would now. I could test it if you're curious? I've been mining with p2pool lately and it's working perfectly. Does Ck's custom S4 cgminer build located here: http://ck.kolivas.org/apps/cgminer/antminer/s4/4.6.1-141018/cgminer still need the difficulty manually set on the pools? It didn't need difficulty to be specified with p2pool. Haven't tested it anywhere else yet. |

Pre-orders are a hard thing to deal with since they don't really fit in the list but at the same time they are options we want to display the numbers for. You can currently use the checkbox filters at the top of the list to hide them.
Maybe they should be hidden by default? Any ideas on how to display the pre-orders are welcome, but we definitely think they should be displayed somewhere... maybe on their own tab?
Very good idea I would have hidden by default. It just sets some false hope with certain ones. Pre-orders are a gamble some great but a lot sadly have not lived up to promises and why most avoid. Agreed. They should be hidden by default, and enabling them should come with a warning about the risks of pre-ordering. IMO. |
