"Dedicated to scrypt mining"

Awwww, KnC, so close, so very close with yesterday's experiment with time-travel.

Shall we say it again a little louder in case you didn't want to hear it properly the first time, "DEDICATED TO SCRYPT MINING".

Your words, not ours.

Not a lot of grey area there. Fairly cut and dry, wouldn't you say?





and in the world of altcoin mining, it is recurrent that the most profitable coin to mine is a coin which you mine at launch, and as soon as possible, cashout to BTC on some toy exchange or other. Call it 'prospecting'.
For me, this has been a good way to make some half-decent profit from altcoins (scrypt specifically)

today, I would recommend that titans should all be mining this, if the miner worked correctly as it was advertised: https://bitcointalksearch.org/topic/ann-positive-innovation-for-multi-payment-cash-solutions-871506

making any kind of profit from LTC mining alone is tough, KfC have INTENTIONALLY misled their customers continually and continue to do so.

Oh KnC, it is fun to see you scrabbling around in the murk of the past to try and re-write history.

Quote from: KnC announcement of the 24th November
When we launched the Titan batch 1 miner and accepted pre-orders we advertised a 100/250 MHs straight-forward Litecoin-miner,

Do be careful you don't end up incriminating yourself as having intentionally misrepresented a product through omission of your, current, claim towards the original sales specification of the Titan as being solely designed to be a 'Litecoin miner'.

After all, whether it be your own archived announcement history, or the wayback-machine archive evidence, the only claim you could possibly make regarding an attempt to imply you were selling this device solely as a 'Litecoin miner', would be the labelling of the web-page you were selling the Titan from being in the 'Litecoin mining' category.

Entirely absent from the explicit specifications you did list for this unit, was any mention of it being intended solely as a 'Litecoin miner'. In fact the evidence from your own website shows you listing it as not just a 'scrypt mining' product but, in fact, it being 'dedicated to scrypt mining'.

"Dedicated to scrypt mining"

i'm sure the mass majority of the people who bought that miner, certainly wouldn't have done so if they thought all they could mine with it was Litecoin.
changing the specifications after the fact is a serious breach of trading standards.

Try changing the voltage/speed of the others? I have some KNC gear that would act like that and required I actually raise the speed of the bum ones above stock, and in some cases lowering voltage. I've also noticed sometimes neighboring DC's if running too high, would shut down the bum ones. Almost seemed as if they were pulling current away from them.



Thanks for the tips, I'll try that. Can't raise clocks above stock, though. 300MHz is the highest selectable speed.

I found a config file in the Titan SD image that had a preconfigured max speed of 475Mhz for the Titan.  To overclock the Titan edit waas.c, recompile and install.

Edit: /home/pi/knc-asic/waas/waas.c

Change this line from 300 to 475:

Code:
#define MAX_DIE_FREQ_TITAN              475

Then:

Code:
cd /home/pi/knc-asic/
make raspberry
cp waas/waas /usr/bin/

Next time you restart bfgminer the advanced page will have selectable speeds up to 475 mhz.

FYI: I had a titan cube overclocked to 400Mhz and was getting about 100Mh/s but the hashrate slipped down quickly over time (even though dcdc's were fine). Not sure why, temps were decentsand everything was working fine.

Might try again at some point.

Note if you are overlocking you had better have damn good connections at the PSU and the Titan.  The one I was overclocking was soldered directly to the Titan cube using TWO high quality 6x PCI-E connections (NOT the cheap square pins with the split down the middle).


Anyone have any luck with overcloking? I have now soldered on the power cables after haveing all my cubes turn the pci-e connectors brown. Tried this with 1.11 and can choose up to 475MHz, but whatever I choose above 325MHz, it is not setting the frequency.

Maybe there is some other files that needs to be changed aswell?

The FPGA on the controller quietly ignores clocks above whatever "IT" has programmed as maximum.
The file that is programmed into the FPGA is
spimux.rbf
It is a proprietary Altera format that is not readily reverse engineered.

There is a possibility that the
spimux.rbf
from a neptune would work on a Tit.
If it did you could go to 500 if there was enough power.
(the problem with the Nep is there is no power even if you did manage to set it higher)

You could also end up with a bricked controller!


YMMV

I am so glad I got out of the mining game and managed to do it at the correct time.

Btw what is the current lowest price for GH/s for a complete product and have we reached the point where the electricity cost has surpassed the mining revenue?

It's getting there if you have expensive electricity.

Antminer S3+, $210 USD, 450 GH/s

income = $2/day
electricity@$.15/kwh = $1.25/day.

I'm not growing my farm now, but the income and spare heat is quite nice this winter.

These attract VAT+duty when imported in the EU, so the total comes around 250USD. Then you need a PSU, so let's say 30USD more.
Total = 280USD

Basically these will never see break even.
Here in the UK these will bring 0.30GBP profit daily  Shocked




this.

we should be seeing a far bigger drop in difficulty than we are. however, from what I see across these forums, there seems to be even more new miners than there was last year at this point. insane.
the only reason I still have 8TH/s running is because my electric is free. If it wasn't for that, I doubt very much i'd have such 'confidence in the price of bitcoin'

 Undecided

I don't think we will see a very big drop in difficulty, because mining has moved from the home of the average person to large industrial data centres where they pay cheap electricity rates.
So these mining companies are still very much profitable.

posts like these crack me up ...

the average miner is invested in equipment they cant sell , so why would they stop mining ?

even if you make $10 a day per 1.5TH after electicity of .13cents/watt its still free HEAT and free $$

in spring and summer when things warm up and you have to spend $$ on cooling that 1.5 TH things will change. 

Its pretty much clear that any gains made in the global hashrate over this winter will be erased quite dramatically when summer starts up again next year

and all these winter miners have to finally dump their hardware.

Since you guys are still taking about KNC here, I am not sure if anyone has seen this...

https://www.kncminer.com/news/news-118

I am not sure what to make of KNC's position on the extra miners that the B1 and B2 owners (including myself) are still waiting for after seeing this and no mention of the Neptune's under their Bitcoin Mining section on their main page.

Thanks,

Well, i am still waiting for a refund asked during May for an order made on February!
Their answer is the same always, "sorry for the delay, you refund is in its way"  Angry

AKA, they haven't mined it yet.

I did ask for a refund a few months ago and declined of course. Was there another way to "cancel" the order ?

Well, I cannot say, yet, whether KnC's failure to meet the specification of "all scrypt applications" is sufficient for an across-the-board liability and obligation to honour every and all cancellation and refund request, however, given that my friend's company's legal challenge to KnC is within their asserted 'B2B' trade agreement meaning that, unlike a consumer product you cannot simply cancel on a whim, the fact they have failed to deliver a device which can work for all scrypt applications and were informed of the cancellation and refund request after they themselves had confirmed it could not mine on p2pool or fast-block-time coins, means the cancellation instruction was not made 'on a whim', but because of there being a serious deviation from the original specifications, with a limitation of use that was not disclosed at the time of purchase, it is possible that said product limitation will expose them to being obligated to give full refunds to anybody who asks for one, or it might be limited only to those cancellations and refunds they were advised of prior to despatch and based on the units being of limited use.

That they are grossly late in delivering these Titans is irrelevant because, as everybody observed months ago, all they had to do was ship one Titan out before the end of September, which I believe is what they did.

That the units didn't mine reliably or at the promised speeds was always going to see KnC excusing themselves with "the promised speeds were only estimates".

That there was now little-to-no chance of ever making ROI was, to be fair to KnC on this point, legally nothing to do with them.

A limitation of use, however, is something that must be disclosed at the time of sale/purchase for a product that would otherwise be reasonably assumed not to have such a limitation. No other scrypt ASIC miner on the market is sold with a limitation on where it can function, the Titan is the only one with such a limit and, even up to the end of last week KnC's sales web-page was touting the Titan as being able to be used "for all scrypt applications" when, the fact is, no, it cannot be used for all scrypt applications.

BTW, I realise actually that the removal of the "all scrypt applications" element of KnC's sales page on their website is because they have posted, "All litecoin mining hardware is currently sold-out."

Which means the offending text contained within the Titan sales description is not there anymore.

For those who miss its bold, confident, albeit false, assertion:
Quote
The Titan Scrypt Miner chip sports 2284 cores running 18272 threads. It can be utilised for any Scrypt-based application

So, KnC, any chance of answering this gentleman's valid question?
http://forum.kncminer.com/forum/main-category/hardware/69437-when-will-the-titan-be-able-to-mine-all-scrypt-based-coins


In my (lay) opinion, this is the very best legal argument available for a refund - the product they delivered was not the product they advertised. I am surprised to see that prominent actions against KNC have not adopted it, preferring the '14 day cooling off' regulations for consumer customers and 'time is of the essence' argument for business customers.

indeed, i can't argue against any of that comment. In fact, i very much doubt we will see any decrease in the difficulty in the rest of 2014.
so... it's all going to boil down to who has the cheapest electric costs? (Dr Bunsen and Beaker will be rubbing their hands at this!)
