This is a thread about Arsbitcoin, not about my phone or my miner.

If I trust a pool, the pool must be worth of my trust, and I should not be worried looking my miners.

So, If this is the answer... bye, bye.

I've just started mining here and now I'm far from my miners. So, I can't change the server.

Bad start, guys. 

Perhaps you should go to cgminer.

It has control system over fan and engine clock (you can switch them or not) in order to set temperature under fixed target (by default 75C). You can define highest temp to stop mining (def. 85C) and highest temp to keep away (def. 95C).

Give it a try. It's sticked in top ten.

OT

I'm curious about your settings ...

OK. Tienes toda la razón. Yo no soy economista y había visto el palabrejo precisamente en artículos bitcoin para hablar del dinero apoyado por el Estado.


Bueno, "fiat" también es una forma verbal del verbo latino por "hacer": "fiat lux" = hágase la luz

;-)

Muy bueno, sí señor.

Sólo dos detalles. El primero un poco frívolo: la palabra fiduiciario sí es la adecuada para traducir el concepto "fiat". Suena a rayos pero es la palabra fetén.

Y la segunda: yo creo que el acaparamiento sí que socava el despegue de bitcoin. A ver; si bitcoin estuviera ya verdaderamente rodado, el acaparamiento no sería tan problemático por las razones que tú apuntas. Pero en el actual estado de la cuestión acapar bitcoins impide que se mueva la moneda, y si la moneda no se mueve entonces pierde valor (=no sirve para nada).

Tampoco hablas de la volatilidad: una web de comercio electrónico que acepte bitcoins  juega con el riesgo grande de que en unas horas la transferencia que le han hecho se haya depreciado de forma significativa.

En cualquier caso, enhorabuena.

To solve a block the second group of numbers should be 0 most of them.

With Catalyst 11.8 and 'cgminer' I can't overvolt my Gigabyte 5850. It locks at a maximum 1.088V

I'll give a try to this.

I'm talking about the one-to-one function y= SHA256(x') where x' is a 256-bit number. I'm NOT talking about general SHA256(x), which could be much more difficult to analyse.

I'm talking about that the effort obtaining systematically pairs (y|x') has never been done until bitcoin. So, it doesn't matter what say the millions of dollars invested because now, with bitcoin, there is a big chance to get deeper in old analysis.

So, if the owner of powerful pool cared analysing those pairs (y|x'), he/she may eventually discover some some (tiny) correlations between bits of y and x', (correlations that only the big computing network of bitcoin can reveal) and take some (tiny) advantage selecting the x' = SHA256(block) vectors that should be the target of second SHA256 round.

Do you understand now?

You are too "naïve"

I thought about this. It has the side effect, that one can analyse 256 bit -> 256 bit function SHA256(x) (x: 256 bit) in order to find correlations between input and output bits.

If somebody cared, the amount of computed hash is so big that it should be give some statistical correlations at this time. Who owns this information can take advantage on mining, because after the first x = SHA256(block) calculus, may be she can decide to perform or not the next step SHA256(x) depending on statistical probability to get a share.

Ok, thanks for the help!

Perhaps a really dumb question but I'm curious if I can plug rightly (without risers and/or extender cables) a PCI-E x16 card onto a PCI-E x1 slot, if there is enough room around in the motherboard.

In other threads I've read that connecting x1 -> x1 cable to x16 card is possible and simple. So I wonder if it is possible doing this without the cable.

I'm happy to see you here Luke! did you test cgminer against eligius? In earlier versions cgminer reported a lot of rejections with your pool.

OK, thanks. I still didn't taste this new version; I guess your damp is a kind of differential control. Anyway, what I have in mind is something like this.

Fi: actual fan value
Ti: actual temp.
Tc: target temp

Pi = Ti - Tc
Di = Ti - T(i-1)
F(i+1) =  Fi + aPi + bDi

where a,b are constants that should be elected after some tryings.  See, that integral control is implicit in the dependence of old value.


I don't think so... I've monitored the fan speed and It shows often near values.

My congrats for the effort and the brilliant result. Just sent a tiny contribution.

Some comments and easy points to score:

* Please, include the last fresh version in the subject line of the thread

* In GPU menu, when I want to change parameters, (key "C") the program asks about GPU-id. The question is pertinent with at least 2 GPUs but with only one... much better go ahead to the only one that can be modified.

And now a not-so-easy point.

Fan control is a bit unstable. I'm mining in my own desk computer, so sometimes I must throttle down GPU (dynamic on). When miner works alone(I=10), at some point it is reached a stationary state, where fan power is stable. But this state is reached after a not so short period of instability, where fan speed increases and decreases randomly. When I work and mine together, the behavior of fan is very crazy.

So I suggest a PID-like control of fan speed to ensure quicker stability. If you don't know about this, I can give some ideas.

Cheers!

It works like a charm! 

Thanks again 

Anyway, thanks for the tip.

Use gpuminer with ADL support.

It manages the fan (and the engine clock, if you wish) to keep temperature to a given value (75 C by default, but I fixed it at 80 C).

I guess you've bought a PCIe x1 -> x1 cable extender
