A 325mh used Titan does 1250 watts vs a 280mh at 1000 watts.
Maybe 1 out of 20 used Titans could still do 350mh now as a prudent speed due to age
A 400mh has better effencency then that
Thus it is so close in electric vs hash imho as to be oranges to oranges and at the point a Titan can no longer be run the same could be said about an A4. They are so close when both get to that point on difficulty you'd be selling either in your stock or more likely both.
As you imply above, due to age these Titans are failing. Today a Titan may be close to an A4 for efficiency, but even with add-on heat sinks, X-brackets and GenTarkin upgrades, these rigs are slowing down. As with any capital investment of computer technology, Titans have a lifecycle and are coming to their end of life. Days, weeks, months, even years, depending on multiple factors but they are declining. Refreshing Titans with A4s just makes sense if you're in this for the long term while you have the hashrate. Now, if we could just see an A4 in the wild that would be huge!. We still don't have the promised Youtube video of the final product, final warranty, release date, RMA process or any evidence that the A4 is close to release other than a web page posting, some emails and a video of a test chip. Fortunately Innosilicon is an established reputable player so we remain hopeful they can overcome their design/manufacturing issues and bring the A4 to market soon. In the ASIC arena reputation is only as good as your next product. Many good companies have gone under as well as bad ones. I would not purchase anything based on reputation, especially an ASIC miner. We need to see proof of a miner hashing away. What is a bit scary is that I read a post that said they only have a cell phone number to answer calls. |

Should be interesting to watch upwards to ~64GH of new/old KNC Titans come online here shortly. Even if you discount 20% due to defect, 51GH of new scrypt hash should be coming online soon. We should not confuse that with Innosilicon firing up a DC with a bunch of new A4s being "burned in".
Speaking of space heaters, those Titans ran at ~4w/MH and these A4s will be running at 3.2w/MH to make their 280MH specification so they will be pushing out their fair share of BTUs....
I would think that what ever KNC had in Titans was running. Not running them would have been stupid but I can't say that they were smart. We are now first week of August and no pics of completed units or a production line with units being built. How about something being tested? You can't put boards together and then ship them out. |

Bad but not uncommon. If they were well funded they would not be doing preorder.

Bump No one is selling his old titan ?  "Old" Titan earns money 2x better as "New" Antminer S9 But I'm always ready to read your price offer for one Cube. Only big farmers from china can profit from S9 ..... Considering that the pre-orders are on for the new scrypt A4 miner,,, I can offer you $1000 for two Titan cubes with 4/4 dies working stable + shipping ... for the record $2400 it got sold on ebay last week a good set of titans 4/4 with the controller ... The A4 miner pre-order is no guarantee of getting a miner. You take a chance with any pre-order that they don't fU. I give it a 50/50 chance. So if you want to gamble that a Chinese company won't FU, then pre-order. |

Yes - I know about the company -- I've bought many 2nd hand A2 machines but not directly from them.
Past experience does not guarantee future experience especially in the world of Scrypt miners.
Every Scrypt miner that I have seen as a pre-order (past the A2's) has turned into Vaporware or some crazy fiasco.
In my opinion one would be a big gambler to pre-order such a machine that doesn't exist.
Sounds like a nice exit-strategy to me -- for a known company to advertise a great new Scrypt miner -- a good price -- and then lead people on for months, years, and zip -- they are gone!
Lets face it -- Scrypt mining is on the way out. Slowly, but surely.
LTC was added recently at Antpool... seems that in China, LTC has still got a big following. I suspect Innosilicon is addressing that market which is a big one esp in China. That is probably a bad new, because the diff can skyrocked if somewho as Bitmain enter to this market; BTW, could be Bitmain one of the Innosilicon's seek new partners? If the diff skyrockets and a 250 MB can only generate 1 LTC a week. At $4 a coin you are not going to have a lot of people wanting to invest millions of dollars into setting up a farm. Also if Bitmain was one of their partners, I don't think they would be out trying to get preorder money to build. Another point is that you would think an investment group willing to setup a huge farm in China, would put up the money to do a big first batch build by Innosilicon. Then they can sell miners to individuals after they get the first thousand built. Instead they are trying to get preorder money to start a build. Not a good omen. Don't disagree with your premise...even with large difficulty jump....but China electric is what 1c 2c kwh or free (for a cut of btc made on the side)... I now with 1000mh and 14c kwy at 4100 watts and 4.08c LTC am making below 24 hours 10.49414062 LTC 42.82 USD 13.78 USD 29.04 USD 7 days 73.45898438 LTC 299.71 USD 96.43 USD 203.28 USD 30 days 314.82421875 LTC 1284.48 USD 413.28 USD 871.20 USD IF SAY THE DIFFICULTY FOR LITECOIN DOUBLES well then I would get this Profitability Analysis Expected Rewards Costs Net Profit 24 hours 5.24707031 LTC 21.41 USD 13.78 USD 7.63 USD 7 days 36.72949219 LTC 149.86 USD 96.43 USD 53.42 USD 30 days 157.41210938 LTC 642.24 USD 413.28 USD 228.96 USD big diff 642.24 usd or down 73.7%....but as you can see the above is still profit after electric and I may be screwed at 14c kwh BUT folk in china with equiv equipment are still killing it ...even if difficulty for LTC doubles Just saying...how they look at this with their electric costs vs my electric costs is a universe apart don't ya know anyway my take on it A lot of unknowns are happening. I think that if there was a chance for a huge profit on LTC machines, someone else in China would have made a machine. Just saying that a company such as Innosilicon has to preorder this sucker. Why? If it is such a great LTC miner with huge potential and the Chinese have zero electric cost, then it should be a no brainer. Yet again this preorder BS has me thinking. I am probably wrong but something doesn't seem right. |

There is always risk, but I have done this before with Zeus and others.
Innosilicon is a well known entity and has earned some level of trust based on prior experience.
Would I send a wire transfer to a startup, no.
I seem to remember people saying that about KNC before things went south with them. I know Innosilicon has built miners before. What bothers me is that they need to solicit funds before they can build. Did they run out of money designing the A4 and so need to front money to build? If they are so trusted and big, why aren't they well funded. They should be able to build like Bitmain and then offer units for sale. Ship after confirmation of sent funds. Not wire me money and then next month or Sept probably send you some miners but no guarantee. This means you have to trust a bunch of people you have never meet before and hope they are honest business people. |

And still no answer from shipping date.
If it really was sent 12.06 than is my shipment lost.
That seems like a very legit question to me. Do you have a tracking number ? Yes the shipping is taking a while. I have order things from China that have taken over 2 months to arrive, even with a tracking number. The lesson here is never ship without a tracking number. I learned this when I sold a video card and shipped without tracking. Guy said he never received it. I had the receipt for postal payment but I had no tracking number to prove it got to him. So I refunded him. If shipment is lost then Qberty needs to do the right thing and refund or ship out new boards with tracking. He made the mistake of shipping without tracking. That is the lesson here. I would give it more time to show up. There is nothing in my history that shows that I should not ship or have lied about anything. Just because I didn't pay extra for the tracking number Tupsu is going apeshit. But honestly, he even asked me for a discount on top of the discount I already decreased it to which was 0.20 BTC. He paid just that. So shipping was coming out of my pocket, so it's up to me what type of shipping I choose. It just so happens that shipping to his stated address costed more. Hence why TXSteve got a tracking number (it costs 9 dollars for tracking to his location), I easily absorbed it. If the shipment was lost, they'd contact me after the grace period. The shipment is doing fine. Again, the tracking number is for the shippers, not the customers. Mainly to prevent humans from saying they never got a package when they did. I did not make a mistake to ship it without tracking. I have no obligation to provide tracking to the customers as a shipper of a product. If the package was honestly lost, I would either refund the bitcoin or ship replacement boards after sorting it out with the shipping company. I'm tired of seeing Tupsu complain. I already said numerous times that I shipped his order. He will get it when he gets it. Calling me a liar or slandering me does not speed up the process of getting packages. Just wait. It is none of my business on how you ship and I am sure you feel justified in your methods. Tracking is a minimal cost and it would prevent this type of problem, with the buyer angry about shipping, lack of visibility of the packages, and their location. |

I have not ordered any boards from Qberty but if I did I would give him a break and let the things ship. Seems to me that people are getting upset over no tracking or the long ship times? People need to chill out and give it time. Why stress over something that has not happened. Has Qberty shipped something to someone and lied about it? Until the facts prove otherwise, give him trust.

This reminds me of Blackarrow. Promises and spec changes. More promises and dates. Then missed dates and promises, all the while they are taking preorder BTC. Finally a few units ship and the rest of the bag holders get nothing but a big FU.

Do you think there will be a A4 group buy. From what has been posted, the A4 is around $1800 USD with a minimum buy of 10. 256 MH/s machine at 1000 watts. Wondering if someone will organize this.

What is a "data hall"? Have seen that posted on btctalk a lot. Don't you all mean "data center"?! Google search did not come up with much..first result to "what is a data hall" comes back with this link: https://en.wikipedia.org/wiki/Data_center....so why do some of you say "data hall" when it appears it is really "data center"? Sorry to hijack this thread but it has been buggin me for a while. Data hall was a term used by KNC for their mining farm in Sweden. I believe people now use it as a derogatory term in referring to a big farm that screws people. |

Why not run GenEthos? My MB is about 5 years old and it works fine with GenEthos.

Wow 3.8BTC for the next batch now. Crazy.
Those who paid 8 BTC or heck even my S7 I paid 5.8BTC for that shoud arrive tomorrow costs too much!
How high is BTC gonna go on this run? Some people may get some sweet deals on S7s but its going to screw the early guys that's for sure!
how does it screw me when i insta-bought BTC to pay for the miner (or used coinbase USD wallet, which is essentially the same). I essentially paid $$ for it (same price then as now) plus will enjoy ~2 extra months of mining, hopefully. It is for those holding BTC and buying with BTC instead of holding. If you spend USD (or get BTC instant to pay for something) I could see how it is a different investment. But if hold BTC and paid at 230 and now it's 490ish you would have been better just holding. So I think it depends on if you paid with a stockpile of coin or via usd/instant BTC for miner. It is always the same story. Someone pays too much BTC and then complains that they could now pay less because the price for BTC has gone up. However think about this. What if BTC tanks now back to the $260 level and Bitmain canceled batch 5 and refunded your BTC back at what you paid. You get back 3.75 BTC worth about $975. I bet people would complain that they paid $1800 for the S7 and not 3.75 BTC. |

Weird. The S7 I order later is arriving earlier according to FedEx. The S7 I order earlier is arriving later.

I paid for a S7 on Sat and they still have not updated my order to paid. I have sent them several messages but no answer. What is up with them.

Congrats on the sale. The KNC titan is still the king. I have more than ROI on my miner. It hashes at 365 Mh/s with power consumption at 1100 watts. Really outstanding.

not everyone cares about power efficiency though. some of us here have access to low cost or zero cost power sources. 16 btc for a machine that barely mines 4 ltc a day? sure you can rent them out but yield is dropping in rental market due to shrinking scrypt coin market (monacoin switched to lyra recently)at most you can get 5 to 6 ltc over there.. anyone who will pay 1200 ltc for this miner will have to wait 250 days (most optimistical) on average just to break even..  also difficulty is going to stay in 47xxx 50xxx range if not shoot upwards while ltc price is going to remain in shitters unless another ponzi pops up. even 10btc for a price is hardly justifiable.. also just fyi official warranty period is over for these capricious miners so if they break you're on your own while Innosilicon and Alcheminer will still repair at cost.. If you have free power then yes run whatever you want but right now if you pay for power the a2 and alchemist miners just cant be run let alone some of the other older miners. So if you pay for power and efficiency is a major factor then make an offer  As far as litecoin difficulty dont know if thats predictable at this point (who is making new scrypt miners vs price). But one could make an argument for either way. I prefer LTC miners over BTC . Bitmine with their Antminer 7 is driving up difficulty. At current difficulty it would take over 9 months to recover cost and this is not counting the drop in reward halving. So 16 BTC is more than fair. If you wanted to do a trade I would give you my two Neptunes including power supplies for your Titan. PM if interested. |

KNC will still repair your miner. I sent them a bad module a few months ago and they RMA it. I got back a fully functional module. |
