Anyone can confirm if this is a scam or not

sorry I realize now I am in wrong section.

NP. At least you realized that right off the bat, kudos ;)
You have have enough posts/activity count that as OP you can either delete or lock it.
Look in lower-left of screen for the options.

I smell a scam. Picture of miner is just an old Titan and the page is quite poorly designed; could be just like the Spondoolies SP50 scam. Maybe they just hired a guy with bad web designing skills, but it looks fake to me. Hashrate could easily be reprogrammed to show a different hashrate than the miner is actually hashing at.

Yep, reeks of bullshit.

And if it isn't KFC are as dumb as ever. Still using that retarded cube design? Still only 1 PCI-e 6 pin per cube? Fuck off.

They state 1300w draw with a provided PSU with 4 leads included. Unless they're using something else than 6 pins... Which would be a pain in the ass compatibility wise when the PSU croaks.

Given the track record of EXTREME UNRELIABILITY of past KnC designs, at least some of them due to VERY STUPID design choices, I wouldn't trust a new KnC design under any circumstance.

 *IF* they are not in fact a scam.



 Dunno why anyone would be stupid enough to buy out the KnC name, given the very long VERY VERY BAD track record of that company.

i wouldn't trust it considering that the original site is   kncminer.com   i.e.   http://www.kncminer.com/

there is no original knc-miner

and there is no contact information except for an email request.   the original kncminer is owned by someone else now, i would think they would have actual contact information to the parent  company.

Well these are usually the telltale signs.. but despite warnings there'll always be one born every 5 minutes..

NO ONE will offer a one year warranty on cryptominers... period.  Even the original KNCminer only offered i think 90 days or something like that.

I think i've seen four new companies trying to "pre-sell" miners this week already.   

I wish Gridseed was still around.  I think there was rumors that they were working on a new one way back when, but it's been silent for a couple years now.

I were just in contact with Gogreenlight current owners of kncminer name. They reply that they already had reported knc-miner.com to the police. So it's a scaming attempt forsure.

I just talked to the real owners and the KnC Miner Titan 2.0 does not exist. They also have no plan to sell products to end-users, ever. This is not the first time people try to do scams in the name of KnC Miner. Be careful when you buy mining equipment, many of them are scams.
I have contacted cointelegraph (advertising for this scam) and coinpayments (processing payments for this scam) but still have not received any reply from them.

yeah my post on the bitmain L3+ thread...this is scam city imho

https://bitcointalk.org/index.php?topic=1864920.msg19039742#msg19039742 (https://bitcointalk.org/index.php?topic=1864920.msg19039742#msg19039742)

2 of the many reasons below....again ....this is a scam ....I have not doubt

It's a scam. Even if knc came back, they would not have a 1 year warranty. They only
had such back in the day, due to website error on original orders, that were not changed from
the previous Neptune product. It was supposed to be 90 days. They fought for that for 2 months
and then caved.

2nd point, if pictures to be seen are true at best they would have to include the
Equivelent of a Corsair 1200i to get 738mh

Especially at 1,500 Price which for eff is still way to much.

Shoddy research and evil prep. Not up to meglomanic knc evil standards.

I call it a scam.

Not even mentioning the fact that the domain name is new as well......(I mean show some evil pride in your work already!)

Cointelegraph has now removed the advertisement and Coinpayments does not longer provide payment service. But the scam is still active using the website and order form.

great work linusdunkers. you just saved lots of souls from blowing away their hard earned money.

Nice Job. I should have probably been proactive and contacted these guys as well to remove, good to see someone is more on the ball on this then myself.

(If a newbie does not get scam'd by an ASIC maker and a bell rings...do you get your angel wings?) lol :)

but anyway nice save :)

probably a scam because i doubt they have the money when with bitcoin they went bankrupt and no way to recover, now talking about doing the same mistake they did, probably fake, but the spec does sound reasonable because at that watteg it match the L3 from bitmain

It would be nice to see a vendor challenge Bitmain for the scrypt market, and although KNC could have done some improvements to their Titans (oh like not fucking running the hotel circuits for all 4 dies on one common bus, two PCIe plugs at least, optoisolators on the signal lines, not using total crap heat paste, a 50 cent DC-DC converter on the Titan instead of sourcing power from the control board, etc) the basic design with OEM power supplies surrounding a chip die was not a bad one. And the cheap-o case is pretty iconic.

Still, the ones they did build have lasted for a couple of years now (in an era where miner operation is measured in weeks it seems) and as long as you don't do the obvious bad things (run them over 45c per chip, keep them around 65mh per cube tops, keep the power supply temps in the 60-70's, don't unplug them while running, don't run them in a fucking horse crap filled barn*, etc) they seem to tick along pretty well.

C
(Why yes I did have to repair one that was chock full of horse crap and hay. That one got the hose....)

Thanks for all the knowledgeable replies guys, yes something inside did tell me this was a scam but there is always a hope for it to be real.....

Once again this community has saved others from losing their hard earned money....great job guys!!!

hi, I find scrypt miner on nodecrypto.com (http://nodecrypto.com) , it is refurbished one it is good price.. somebody know a better product or price of scrypt miner ???

 Gridseed merged with WiiBox to become SFARDS - their SF100 was a serious failure, wasn't competative on the SHA256 side by the time they released it, and WAY too high priced on the Scrypt side.
 It also had some serious reliability issues, per some of the very few folks that ever managed to get of one.
 I believe they built one batch, managed to sell that single batch off, then gave up entirely on cryptocoin as nothing has been heard out of SFARDS for a long time now.


 The Titan was notorious for going bad due to DIES on their chip dying, not just the horrible board-level design choices they made. Arguably the lowest reliability design anyone ever produced, though it was the long-time king of efficiency for Scrypt when it DID work.



 I would be EXTREMELY cautious about that "nodecrypto" site - NOBODY makes a 900 Mh Scrypt miner at this time, and the prices are very suspicious on their L3+ listings (and how the heck are they supposedly having REFURBISHED L3+ units).
 I smell a very strong wiff of "scam" out of that site.

likely a scam site..you can mine those on www.prohashing.com (http://www.prohashing.com) for more than they are asking

so I call scam

so don't do anything with out escrow from someon YOU PICK at least

 Actually, it's more accurate to say that BitMain has challenged Innosilicon in the scrypt market - and appears to probably be winning.

 I'm not sure if the TOTAL hashrate for all Bitmain Scrypt miners has passed the TOTAL hashrate for all Innosilicon Scrypt miners yet - but it's getting close if they haven't done so.


 Miners living for years is NOT uncommon - the long-time issue was always more about "miner is no longer profitable after a year or two, shut it down" in SHA256 due the greater competition.

 I've got A2 units that were bought USED from Zoomhash (who had mined on them likely for a year or two BEFORE they sold them) and I've had for almost 2 years now, have had ZERO issues with them other than a couple of the fans dying and needing to be replaced and one PS that died early on (the original PS was a bit underrated for the 110 Mhs units).
 The actual MINERS however have been rock solid reliable despite probably being 3-4 years old now.

oops Scam site is now offline. Good work

I disagree. Run Titans at 60mh per cube and they will run pretty much forever. The errors came when people ran the things at 80mh, which caused:

1) Dies to fail from too much heat. I have seen boards with burn marks on the back.

2) Power supplies running too hot. Once again have seen supplies with caps and FETs that caught fire.

3) FPGAs on the controller blowing up: This is caused partially by a crap design, part because people unplug the miners from the controller while running.

4) Removing and replacing the heat sink without new thermal compound (it's a one time use).

5) Running miners in barns, sheds, and places where either there is not enough cool air or there is literally horse crap everywhere (oh yes, I have had to clean those miners....)

6) Torquing the bolts so tightly the board tacos (this can be addressed by putting one of those rubberish thingies under the board between the front two posts).

7) PCIe power plugs burning due to crappy power supply cables or running too hot (don't use a little supply with cheap wires. Bad)

They weren't the best miners in the universe, but they weren't too bad. With the exception of 3 (and that's a biggie, using fucking optoisolators would have made everything ok) they're pretty good at 60mh, <42c on the die, under 70c on the supplies. Exceed that and things get more complex.

YMMV.

 Per KNC's stated specs, they appear to have *supposedly* been designed to run at 80 Mhs - like the A2 was "base clock" at 1000, but if you upgraded the OEM power supply they have proven to be rock solid reliable at 1200 (the OEM power supply was only rated for 1100 watts, which is comfortable at 1000 Mhs clock but VERY marginal at 1100 and NOT ENOUGH at 1200).

 The PCI-E connectors even at the 60 Mhs level were very marginal for the power draw, though not much worse than the Spondoolies SP20 (which was NOT notorious for flames as it had power limiting in the controller).

 A LOT of the reported fails were on machines that the user had NOT done any form of "modifications" to.

 A2s are quite comfortable running in high ambient temps in "turbo mode", they have some SERIOUS airflow through the cases and lots of heatsink for the design power dissipation (though the 2 fans in the rear of the case were a waste, nice to unplug them to have around as spares though).

 Compared to the A2, the Titan was JUNK on reliability (except the A2 original power supply if you pushed it too hard), mostly due to BAD DESIGN DECISIONS that required folks to run them WAY too hard to meet their stated hashrate spec.


 This also wasn't new for KNC - at least 2 of their SHA256 miners had the same sort of issues, the Neptune might have even been WORSE on the same points.
