1  Local / Mining (Italiano) / Re: le migliori Schede Video per minare doge? on: February 15, 2014, 02:50:49 PM
potete consigliarmi una scheda madre,un processore e quanta potenza serve all'alimentatore per 2 sappirhe Toxic?
Per i futuri calcoli sappi che quella scheda video consuma 280W l'una...una scheda madre con solo processore e HD attaccati consuma sui 105 Watt (dipende molto dal processore ma di norma intorno ai 90 Watt il solo processore).

Quando decidi l'alimentatore oltre i watt fai i conti del rendimento dell'alimentatore...esempio...se l'alientatore rende l'85% ed è un 1000 Watt utilizza hardware che non superi gli 850Watt per stare tranquillo Wink

Il rendimento non va considerato così. Se l'alimentatore è da 1000 W con un rendimento del 85% al carico massimo, i componenti possono consumare fino a 1000 W (bisognerebbe guardare la corrente sulle singole linee però), poi l'alimentatore si ciucccia dalla presa 1000 / 85 * 100 = 1176 W.

Piuttosto è bene non caricare mai al massimo un alimentatore per non distruggerlo in fretta, fra l'altro l'efficienza massima si ha quando l'alimentatore è caricato al 50%, poi più lo si carica più scende, è bene guardare le specifiche per scegliere l'alimentatore.

Io ci sono morto dietro le mie 2 7950, specialmente per farle andare sotto windows, ma ora sto utilizzando BAMT.
Le configurazioni che ho usato sono queste (la prima con BAMT, la seconda sotto windows 8.1):

intensity   20   17
worksize   256   256
lookup-gap   2   2
thread-concurrency   40960   15236
shaders   0   0
gpu-threads   1   1
gpu-engine   1060   1060
gpu-memclock   1500   1500
gpu-powertune   20   20
temp-target   70   70

con entrambe ottengo 630 kH/s

I'm trying to compile the client on debian squeeze.
First it cannot find the splash2.jpg file in the images directory. I resolved linking to the icons/splash2.jpg.
Then I receive the following error:

do you have boost installed?
Yes, I installed the dependencies as indicated in the readme-qt.rst file:

        apt-get install qt4-qmake libqt4-dev build-essential libboost-dev libboost-system-dev \
        libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev \
        libssl-dev libdb4.8++-dev

maybe the libboost version included in debian squeeze is too old? It is 1.42

I'm looking for a 32 bit linux version. I tried to compile it but with no success.
There is a precompiled 32 bit linux version?
