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...

I respect your thoughts... that's why I ask...
...and why the info struck me as odd...
Yeah...  the bags did give me a chuckle...
There has to be a better way for Him...
Like getting the thing out of that cold basement...

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):

Unofficial/beta firmware addressing the die #0 failed issue:
https://bitcointalksearch.org/topic/knc-die-0-disabled-323116 (see 2nd post)

Is good idea for a good miner to install firmware 0.98.1?

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?

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.

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.

I was warning about sensor placement (go read my previous post on why!) and you insist on ignoring what I write. Stop distorting what I said!

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!

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. 

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 ?

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?

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".

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.
Emily even stated in an e-mail---rated to 105...  
Do you really think they meant temp from some other source than the thermometer reading they provided? ....lolz.

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

Try going back to 0.96

Thanks. Edited above post accordingly.

When are people going to get it through their heads that ghash.io is NOT a "bitfury pool" - it was a private pool that has nothing to do with BFSB, or MBP, or Tytus.  ghash.io is NOT the 100TH mine.  Anyone that puts out at least 1 Gh/s can mine there and sell their output on cex.io.

They happen to mention Bitfury gear on their OP, but I know for a fact there are many KnC's mining there - they don't restrict the hardware you use.  It started out as a pool for some private board builds using Bitfury chips, but is now open to all.

Looks like 0.98.1 beta did not help out my dead die.  Its been running for an hour and the current has only improved 0.1A, not enough to bring it to life.  That's a bummer.  Looks like its RMA time. 

Yeah, I rebooted and got rid of BertMod. Does not work well on my machine. Everything is back to current "normal" of 269 avg hash & WU of ~3800. Also, adjusted the bags to block the heatsink slightly less, to be safer.
