681  Bitcoin / Mining support / Re: Bitmain AntMiner U1 Tips & Tricks on: April 29, 2014, 10:03:40 AM
How can I overclock the u2 (supposed to be u2+'s  I got) with bfg past 2.2?  I have two plugged in my desktop doing 2.2 with - hw errors so I know I can take them higher.....

You'll need a few of the correct resistors to solder in, a fan, some heatsinks, and a powered USB hub.  Then, look at https://www.bitmaintech.com/userfiles/download/AntMiner%20U1%20user%20guide.pdf

Sorry, but that was to the the U1.
The U2 already have the resistor soldered on and the heatsink.
All you have to do is use the correct version of CGMiner and input the correct frequency parameters, as described in earlier posts on this same topic.

That's odd I have 3 Ant's with board 1.2 (I think that they are really U2 because they came with the larger heatsink and the board layout it's a bit different) and none came with the R2 resistor soldered, tomorrow or maybe the day after I'll receive 2 more and i'll check if they have the resistor soldered

Hum, you might be right...
In this photo

I can't find see the R2 resistor soldered...

But then,


The Antminer S2 does not appear to have the same resistor configuration.  Has anyone looked into what would be required to increase the voltage?

Did you meant "U2?
I read somewhere those already have the resistors soldered on.

Yes, the U2.  They do, but they seem to have OC issues at anything higher than 2.4Ghash.  Seems to be a voltage issue.

So, now I'm confused.
Can somebody clear this up, please?

I've found that in fact some Ant's come with the R2 resistor soldered



I think that those are called U2+ the others are just U2

Great...!!! Now we have to be aware of possible scams when the seller claims they are U2+ when in fact they're not...
Thanks for the info!

Fazendo as coisas com muita cabecinha e não carregar no botão de buy ou sell com o coração/emoção/receio/etc, podes obter bons lucros a fazer scalping em qualquer exchange, tendo em conta, claro, o volume de negócios e o crescimento (ou não) das moedas que utilizares.

coinbycall is down since many days! not reachable, server error, etc.

i don´t listen radio without knowing whether I get paid for it.


It's true the site has been having some quirks but I've been paid yesterday.

Não há volta a dar...
Afinal de contas, o que nos une são estes bytes reluzentes!!!
Vou apanha-los todos... são, meus, meus, meus!
Meus preciosos, meus reluzentes, meus!

(Ora aí estava uma gira: reescrever o sr. dos anilhos trocando o anel por uma wallet, um blockchain ou bitcoins!!)

Transacções dessas importâncias eu não tenho!!  Grin



Mas confessa lá, também querias, não querias!? Cheesy (também eu!)

Olha o desaparecido do sobrinho!!! Cheesy
Eu estive aqui a dar voltas ao miolo e a este disco e de facto, não poderei nunca tirar prints da minha primeira carteira, já que a mandei à viola depois de transferir o conteúdo.
Mas tenho umas transacções giras com uns aninhos na actual.
Se calhar, por curiosidade, vou espreitar no blockchain.info a primeira transacção, quando mandei para lá o conteúdo dessa carteira!

Mike, mine has been working fine, for now. Never the less, I've backed up the private keys. It's always an advisable security measure.
Could you please shed me some light on the "Change Back" question?
Thank you and keep the good work.
691  Other / MultiBit / Re: Multibit turned out to be a scam on: April 10, 2014, 08:50:26 AM
If multibit were to be a scam, the addresses would belong to someone and not show in multibit's user wallet.
It's just pure amateurism as many services surrounding bitcoin - but that doesn't turn the bitcoin itself into a scam.
Some of those who claim bitcoin is a scam or a ponzi are either those who scam, those who run the ponzi schemes or those who don't stop for 1 minute to seriously think about what's being offered by others or to take security measures.
I've been testing multibit for weeks, the addresses in those wallets were used just for receiving but later today, I'll be exporting all my private keys and importing them in bitcoin-qt to prevent any surprise, until all of this bug has been sorted out.
It's only 7 bitcent worth, but it is something.
By the way, I haven't quite understood not even found information about the "change back".
Could anyone be kind enough to explain it to me or at least, point me in the right direction, as I've never experienced it on any transaction I've made on bitcoin-qt?
Thank you!

Pois, naturalmente.
Mas é um belo print! Cheesy
693  Local / Portugal / Re: Momento de Nostalgia on: April 09, 2014, 02:15:35 PM
Nice!
E só por curiosidade, se não for indiscrição, qual o total neste momento? ou esvaziaste-a totalmente?

I am not an electronics guru. I am a merely man with some soldering equipment and a willingness to injure myself and damage sensitive electronic equipment.

So pardon me if this is a silly question...

Am I to take it that by replacing the resistors per this chart we can increase the voltage and thus reach the hash rates beyond the published overclockable speed? (Which would presumably require increasing the ability of the U1 to dissipate heat.)
Huh

I am having a hard time believing it would be that easy but the ASICMINER upgrades were (after a huge thread of experiments by many talented individuals https://bitcointalk.org/index.php?topic=241652.0)

The Antminer S2 does not appear to have the same resistor configuration.  Has anyone looked into what would be required to increase the voltage?

@alfmar, o AntMiner S1 está esgotado.

Tenho para venda ainda 2, 500€ cada, apenas os vendo pois vou ter tb os Dragon para venda, no entanto as primeiras unidades que chegam no final desta semana já estão vendidas

Agora é que me perdi mesmo... quais são os "Dragon"? Cheesy
Obrigado!

I'm unable to access the site for 4 days.
Is it everything ok?
697  Local / Portugal / Re: Portugal OFF Topic on: April 02, 2014, 11:23:21 AM
Obrigado Adriano

Por acaso também li os mesmos links.
O problema é que eu não tenho conta na Coinbase em nenhum dos endereços onde recebi esse mail.
Só me preocupa que vou ter de os mandar dar uma voltinha trocando os endereços numa série de sites. Cheesy
Quanto à maneira como a Coinbase está a lidar com o assunto é precisamente mais um dos motivos que me leva a nunca lá criar conta por motivo absolutamente nenhum e desaconselhar os meus amigos de o fazerem ou de terem sequer lá algum valor.
698  Local / Portugal / Re: Portugal OFF Topic on: April 01, 2014, 06:28:30 PM
Não, não, não, Raoul!
Eu também quero é 99999.9999BTC!!!
Mesmo que fosse para os enviar a alguém, tinha de me sair primeiro o euro-milhões!!
(Ou apanhar umas quantas carteiras ao Satochi? :p)
699  Local / Portugal / Re: Portugal OFF Topic on: April 01, 2014, 04:34:23 PM
Cheio de sono...
Alguém recebeu mails da coinbase a pedir pagamentos de 99999.9999BTC? (também quero!!!)  Grin

Caaalma Wipeout!
(Ps, eu adorava esse jogo!!!)

Antes de mais, um consumo de zero watts é fabuloso. Quero uma dessas!! E um unicórnio fêmea. Cheesy
Não coloco em causa nada do que disseste.
Alias, é precisamente esse o desdobramento que tentei promover com a minha "tabela" e pelo qual te agradeço já.
Como disse antes, estou um bocado a leste das Alt por diversas razões.
Os preços não tenho os valores correctos, especialmente depois desta liberalização, mas alerto os demais que se trata do preço por Quilo Watt Hora.
Assim sendo, temos 55w*12h*0.00017€/wh=0,1122€ + 55w*12h*0.00007€/wh=0.03696€ para um total de 0.14916€/dia.
Em 30 dias teríamos um custo (bruto) de electricidade de 4,48€.
De facto não é muito para uma gráfica em scrypt.
Agora, não nos podemos é esquecer que a gráfica precisa de um computador a funcionar, desktop de preferência e aí o consumo upa upa.
Supondo que já se tem uma Raspberry e supondo mais do que uma gridseed, não ficaria mais em conta pelo menos em termos de consumos?
Não me leves a mal as questões, estou somente a tentar criar um consenso: uma pode não servir para nada, mas a partir de que número seria rentável.
