The ethernet controller is the same of the Tube ?

You have a new firmware ?
22  Economy / Service Announcements / Re: Avalon4(A3222) 28nm Chips are now on sales @ ehash.com on: September 12, 2014, 09:22:27 PM
For anyone who can't be bothered to use their brains, the prices are specifically high because they are SAMPLE chips. Its to discourage one developer buying more than they need which is unfair - Avalon will only have a tiny batch until their actual batches for SALE come in.

Hmm i think they should be free for established proven developers.
Such strategy is better for chips adoption.



They don't need better chip adoption, there is limited supply and they have to open it up as a level playing field. There are more developers than there are chips.

Asia has been busy buying 1,000,000s of Avalon chips while the forums have 'boycotted' them thinking its still Yifu when they quite simply don't care. This isn't the company Avalon, this isn't the company that did trade ins, this isn't the company that random batch 1 2 and 3. If people don't want to buy, they don't have to.

You will receive a module to test ? If yes, when ?
23  Bitcoin / Hardware / Re: ASICMiner Tube Sales Information Thread [Round3, Price at <1btc per TH/s] on: September 07, 2014, 06:35:00 PM
My 3 tubes are hashing  at  196 to 210 GH/S per board for 2.45TH/S total at stock clock, with 1 stock fan.

Am I just lucky, or is it something I've done differently?

Well, I'm not sure, so here are my observations.

1. I think assembly technique is important. I applied the thermal pads to the heat sinks first, then made sure there were no air bubbles under the pads. Then I used an impact driver to tighten the screws in a random pattern so as to equalize board contact with the heat sink. I have the fan blowing "in", and faced the handles "out" as some others recommended.

2. I used high quality power supplies providing at least 250watts per blade.

3. I placed the tubes on a wire rack shelf providing airflow to all four sides.

4. I'm using Slush's pool with bfgminer 4.7 as a proxy. I know it should work fine without the proxy, but I hesitate to mess with success. Wink

You are using one or two pcie power connector per board ?

Only one for now. It's near impossible to find power supplies with 8 independent pcies, e.g. separate cables all the way back to the ps.

The cables get hot after a while or they are holding well ?

26  Economy / Computer hardware / Re: LA 1.5TH - 1150USD - BEST PRICE! on: September 03, 2014, 08:00:28 PM
Wrong. taken Direct from their thread:

Type 1:  Dragon 1.5T miner with initial PSU; 999$ :
Order link: http://www.easy2mine.com/goods.php?id=75

Type 2:  Dragon 1.5T miner with upgraded PSU(Great wall 1250w):1039 $:
Order link: http://www.easy2mine.com/goods.php?id=76

Both are too expensive.

The cost to buy the tube, S3, T1 is much smaller per GHs

I haven't heard anything about this chip, anyone knows the specification ?

Their last chip (A3233) was worse than the competition.

We can hope for a better product now ? What do you think ?

Did you received the units already ?

Just finishing setting up my Rockminer T1 800-900 Gh/s ASIC Bitcoin Miner!

Here is a pic of my  hashing away:

And the speed:

898 GH/s!!!

Thank you Rockminer and Alex for helping me set it up Smiley


Each board has one or two PCIe power connectors ?
32  Bitcoin / Hardware / Re: ASICMiner Tube Sales Information Thread on: August 20, 2014, 01:20:29 AM
1. The miner can not directly run with f2pool. If you want to mine on f2pool, you need a PC or a raspberry PI
with a mining proxy. The ethernet controller needs to be pointed to the proxy instead of the pool.

2. We now offer the shipping of fully assembled devices. If you need them to be shipped as a whole please specify
in your order. We still prefer separate shipping though, because it will reduce the potential shipping damage significantly.

3. The ethernet controller needs a 12V 1A DC input. You could either use a separate AC/DC for it, or wire one
directly from your PSU for the hashing boards.

4. Shipping to countries outside mainland China is free.

What is the MOQ for fully assembled devices ?
33  Local / Português (Portuguese) / Re: Alguém já usou brascoins? on: August 18, 2014, 10:26:23 PM
Realmente o Brascoins oferece os melhores preços, é só melhorar o método de pagamento.
34  Bitcoin / Hardware / Re: ASICMiner Tube Sales Information Thread on: August 18, 2014, 02:45:33 AM
You should decrease the MOQ to 5 full sets.
35  Bitcoin / Group buys / Re: [OPEN] ASICMiner Tube Group Buy #1 on: August 17, 2014, 11:48:41 PM
Is this GB over?  I sent payment on the 16th, did I miss the deadline?

Thanks!
Nope, you're good.  My order to fc went in by 16th.

I have an internal tracking number that will get out order to Hong Kong, then it's picked up by DHL.
So I expect these in a few days after DHL number is provided.

How many you ordered ?
36  Bitcoin / Hardware / Re: ANTMINER S3 Discussion and Support Thread. on: August 17, 2014, 11:04:58 PM
Anyone knows how to determine the batch number of the ANTMINER S3 ?

There is something like a serial number in the product ?
37  Bitcoin / Group buys / Re: [OPEN] T1-BOX RockMiner production, small batch on: August 17, 2014, 06:41:50 PM
They now have specs up on website for the T-1.
 
HashRate: 780~840GH/S ;
Power Consumption: 1000W;
Cooling: Air cooling system;
General Size: 250mm*250mm*200mm
Blade: 250mm*150mm
Net Weight: 4KG
PSU: 4*6PIN PCI-E
Controller: BE Controller
Noise: 55-60DB
(note that last couple of their models were at the high end -- or slightly above -- noise estimates)

Price looks comparable to other miners for sale right now. Would love to get my hands on 1 or 2 but don't have enough right now to order the minimum of 4 from Rockminer directly.
Noticed that Zoom has them listed on their site already but you can't actually add one to cart yet (yes I tried multiple times). Anyone run across a US reseller that has them in stock yet?

The price just increased from 4.6 BTC to 5.3 BTC.

It's better to buy the tube from the other canary group buy.

Comprem seus Bitcoins com pessoas ou exchanges aqui do Brasil. Ajudem a nossa pequena economia Bitcoin a girar

A diferença depois das taxas e tempo de retorno dos Bitcoins não é tão grande assim ao ponto de comprar de empresas de fora

Então, só vejo o mercado bitcoin aqui no Brasil e o preço normalmente é mais alto do que o "mercado".

Existe algum outro ?
39  Local / Português (Portuguese) / Re: Alguém já usou brascoins? on: August 17, 2014, 02:43:30 PM
Já comprei la no passado mas a empresa aparentemente deixou de ser honesta.

Eles implementaram limites baixos (tipo R$500 ou menos) para que o usuário seja obrigado a fazer varias transações e pagar mais taxas.

Portanto não recomendo de maneira nenhuma.



A empresa AstroPay estabelece limites de pagamento baseada no sistema mais seguro do mundo. Esses limites não tem relação alguma com os limites da nossa empresa, Brascoins (R$ 50,00 até R$ 10.000,00 por operação), portanto não é verdade o que o senhor diz, nós não disminuimos o limite para que os usuários sejam obrigados a fazer várias transações e pagar mais taxas, nosso limite continúa sendo de R$ 50,00 até R$ 10.000,00 por operação.
Conforme nós informamos ao senhor por e-mail deve entrar em contato com a AstroPay e criar un histórico de confiança para que seu limite seja aumentado.
Também sugerimos explicar quál o problema, com certeza tería sido resolvido. Se o senhor tivesse explicado o que disse neste fórum já não tería o problema  Wink mas somente disse "Estou tentando fazer uma compra pelo AstroPay mas não esta dando certo." Por que?
Lembramos que a empresa AstroPay é quem podería ter liberado seu limite, não o pessoal do fórum.
Sínta-se a vontade para comprar seus bitcoins no site que preferir.



No passado fiz compras maiores sem problemas, porque eu perdi a confiança ?

A situação me aprece muito comoda para vocês, ao colocar a culpa no AstroPay e oferecer apenas esse método de pagamento.

O honesto seria colocar que o limite é contingente ao que o AstroPay permite, uma vez que esse é o único método de pagamento.

E eu não permiti que vocês colocassem meu nome e email aqui no fórum.
