Swedish ASIC miner company kncminer.com

[FeedbackLoop]

Had an interesting incident last night. I check my email after six hours and it says the KNC is dead, so I check with Putty and line after line says the share I'm submitting is from the previous block. Anyone else ever had this happen? I'm not sure if it is a cgminer error after running for 3 days or if it's because I'm playing around with a hotter miner. Anyways, resetting the miner worked and it's back to normal. We did have slightly warmer weather yesterday, but I never saw a temp higher than 48 on the miner. I would have grabbed a screenshot, but was worried I bricked the miner. lol  If it happens again, I will grab one though.

Just a note about the temps. I really don't think they are measured at the ASIC so careful with those. Wasn't it you measuring them with an IR thermometer though?

I just gotta say.....Bullshit... I ran 2 of my Sats all the way up to 95C.
All 3 sats love to run at 70C, that's the "Sweetspot".  How can you be warning peeps at 48C? That's just not correcct... at all.

Call bullshit all you want but re-read what I said. I was warning about the placement of the sensors not the temperature itself. In my experience I can stop the cooler fans and the temperature will barely rise. If I stop the case fans it will rise some 10 C. I cannot say for sure the sensors are not on the ASIC but I still think it's a nice warning to the most daring mod posted here (covering the coolers with plastic bags), especially if the temperatures reported are in the 40-50C and he was getting problems. I even asked about the IR sensor precisely because I am not sure.

If you re-read my posts you will see that I am not a "defender of cold temperatures" at all (and if I genuinely were, why wouldn't that be correct?).

After that tell me what exactly is "just not correct at all".

Do you really think they meant temp from some other source than the thermometer reading they provided? ....lolz. That's just ludacrist.
and by not correct..I specifically mean you warning peeps about 45 degrees, when KNC specifically said "up to 105"...   Are you trying to confuse people?...  Those are the specs. Period.
45 degrees isn't even half the rated "max temp." You can't understand that?

Anyone that puts out at least 1 Gh/s can mine there and sell their output on cex.io.

Sorry for the slightly out of topic, but how does this work? You point your miners to ghash.io and sell your hashes on cex.io?

I thought ghash.io was just a pool for miners and for those who bought shares on cex.io ?

no, you cant sell your hashes on cex.io, if your miners are pointed to ghash. only in-house hasher are for sale, and your miners get btcs like on any other pool.

I run mine at 69C reported and I posted a lot about the improvement from hotter temperatures with my own setup. What the hell is your fight? Do you think there is a "cold KNC" conspiracy out to get you or what? Seriously, some people will take anything posted as a personal fight. Get off your high horse!

Are you also selling your BTC for fiat? If not, to get a completely honest answer you should be doing your calcs in what you would have paid in BTC when you ordered. BTC has appreciated significantly against the USD since you would have ordered.

this dogma will never die here..   I guess it is a clash of old btc-in-hand miners vs the new credit-in-hand miners

the new credit-in-hand miners take your equation and find out they would have paid 0btc for miners since they wouldn't get a miner if they had to try to buy btc on credit first..  would be a total waste of fees if possible, so they just keep the equation in $$$ and factor in the increase of btc value as part of their investment.

I'll say it again.. for a lot of the new miners, there is no 'if you bought it with btc' or 'if you just bought btc'

are all the old miners myopic??  staring at hashings screens for 2-3 years probably does that

Agreed. If you have 50 BTC and have the choice to buy a rig with it (that may or may not break even or even arrive) or just keep your BTC buying a rig is stupid. Buying a mining rig to possibly return what you already have, plus the avoidable risks inherent in the system that are solved by Paypal or CC protection. The very last thing you should use to buy with bitcoins is a miner to create them..it's illogical. Even more so given the past scenarios when people found themselves up shit creek after buying BFL and other manufacturers rigs in BTC.

If the value of BTC rising is your game you're better off trading them properly with leverage and being able to gain from both rises AND falls in value rather than sitting on them .

I paid in dollars, if my rig makes me more than I began with...that's a profit. Simple as that. I can make more in a month trading BTC than any rig should I be up for a gamble, but compared to buying rigs from unknown companies it's a lesser risk.

As for rigs that have run for a couple of weeks and made 1/3 of their value back...that means that so far difficulty hasn't shot up is all. It doesn't mean they will break even, unless the BTC value continues to rise. A week earler on time delivery would have missed a huge increase in difficulty and they would maybe have been 50% or more recovered by now. By Xmas we'll all be crying when we see the amount they manage to produce even compared to now. We knew that though, but we had the word of KNC to deliver to rely on to make our decision. Those early days let us all down badly and some people who lost out over 2 diff increases were royally screwed.

Reality seems to be the enemy of people buying this gear.

When are people going to get it through their heads that ghash.io is NOT a "bitfury pool"

Probably about the same time they remove this from their login page:

+1

Re-reading that I don't feel sorry for thinking it was associated with Bitfury (in fact isn't there any link really? I would really like to know). My initial post, as quoted, remains valid in the sense that the current allegations about Ghash.io may indeed hurt Bitfury's reputation (to the benefit of KNC which was the context in which I was replying to). The allegations against ghash.io are serious and the evidence is compelling.

I respect your thoughts, so I'm trying to understand what the hell you are talking about...
Then why did you warn him to be careful, when he said his temps barely reached 45?  
What is to be careful about then considering sensor placement?
I'm even more confused now.....
What is the point?
What is the concern/why should he be concerned with the sensor?

I think I was quite clear but here it is again distilling the arguments for different sensor placement THAT I KNOW OF (again I am not attacking you and I was not trying to prove anything about sensor placement, I was just giving a word of caution.)

Sorry to the readers that have read this already above and that are getting tired of a 1000 page thread:

Reasons to warn another user to be cautious about the assumption that the sensors are placed directly on the ASIC:
1 - user's unit has bags wrapping coolers instead of fans and is reading a low temp
2 - unit mentioned above started having problems (should we abstain from posting one line of concern to not get anyone offended??)
3 - my own posted personal experience removing cooler fans (small increase of T) versus removing case fans (large increase of T)

Reasons to not warn another user about the assumption that the sensors are placed directly on the ASIC:
1 - Emilia said so apparently
2 - hot is good and we don't want to mislead other users that can only read 1 page back in the thread.  


Frankly KNC's customer support told me a lot of things that were not true before because they wanted to rush me (such as 5 different delivery dates and different locations of the unit). Perhaps that has changed but forgive me for posting warnings based on observations to a guy with plastic bags for fans (which I think is totally awesome and have reposted before but still plastic bags for fans):

Strange things happening...

I tested the Jupiter on p2pool last night for an hour.
When I brought it back to Eligius, It starts hashing faster than it ever has...

Sorry if I sounded aggressive. You were the main person who made me take the jump to a hotter setup back in 0.95. You are also one of the few taking the brunt of the (voluntary) effort to  give support here. You deserve a lot of credit for that (from KNC also)! It gets a bit hard to not get a bit defensive when you see some people acting way too sensitive to well intended posts (fortunately for me, so far, I only had one of those which I mostly brushed off but you do see it a lot here).

Ditto...sorry if I sounded jerk-ish, Ewok didn't mean it...

BTW...
I just ran Bertmod for the first time,
It showed all cores on all machines at 100%, except one had 3 cores on a single die...dead...
I tightened the screws a bit more on that board... (very tight)
It brought them back!!!!
Bertmod is awesome!
Now 100% on all boards!

edit...spoke too soon... they shut off one by one within two mins still...  
will try to coax them back....

How does Eligius pay out directly from the block then if it must receive the block first???

... in pool "mining" there must be an entity to receive the reward, what is not the pool participant. The reward needs to be transmitted (first transaction) to the entity which "solves" the block.[/b] You are failing to understand that the receiver (thus the "solver") it is not the pool participant.

That is not a correct statement.   p2pool and eligius are evidence of that.

The pool creates a coinbase entry assigning the block reward to itself.

That is also an incorrect.  Note the specific pools I named.  If you don't know how they work well thats fine but it might not be a good idea to provide "corrections"

True.

I was not aware that Eligius pool had changed their way to pay the shares. So you are right, my statement was incorrect.

https://en.bitcoin.it/wiki/Eligius

When a block is found, all miners who have reached the minimum payout threshold (currently about 0.17 BTC) are paid via the Generation transaction.

I am sure everyone has read through and absorbed this nugget, yes?  If not do so and see what most likely lies ahead.  Not to scare anyone, just to be an informed miner.


Estimate of ASIC pre-orders: 11 to 13 PH/s (diff 1.5B to 1.8B) by end of 2013

Go thru that list and laugh at all the failure....

ASICMiner? Haven't shown much as of yet and gen 2 was a fail.
Avalon? Lol...outdated chips and they screwed the entire community.
Hashfast? Delivery before Dec 31st they are now saying....many of their cusotmers are realizing that they will never make money and are jumping ship.

Bitfury...legit deliveries...only real competitor right now.

Basically everyone who bought late is now asking for a refund and they intend to buy instead of mine.

I'd say there will be no where near the difficulty that thread is proposing by the end of the year.

It's got maybe a couple more big jump in diff left and then it will stall for a bit.

The network hashrate has been growing by over 100TH per day. Even with KnC having shut down manufacturing till mid Nov, and ASICMiner/labcoin/tytus/HF/cointerra are late, the network is still growing at an increasing rate

Regarding temperature sensor data, I decided to do a simple test...

Dude I've said Bertmod gives VRM temps, as has Uski.

Reporting back on FW 0.98.1

Jupiter 3 with 2 bad dies was hashing at 487 GH/s

20mins in with FW 0.98.1 I'm now hashing at 526 GH/s 

Still not 550- but I'll take it.

Thank you for your report. Anyone tried to upgrade already good miner?

I dont know if I have to risk messing it up
