How much international shipping and handling in Europe?

Thanks W_M

Technobit are in the EU, Wolf_Miner, so no import duty or any of that nonsense.

Nice, any pictures yet?

It looks exactly like a Hex16B I suspect. Same 55nm chip package just 25% more hash on Bitfury v2. Wink

$35 in FEES???! Seriously? Yikes...

What people don't realize is that Ebay & PayPal are the same company so they in effect charge you twice. LOL Tongue

Hi !

I ordered the 130 Version
Order Reference QSUFGPQFI -- placed on 2014-03-06

at this Point the Homepage shows 499 Euro with Shipment March

Today i checked the Status and the Homepage shows
130er Miner at 409 Euro and Shipment April 7th

Mhhmm ok lost 90 Euros cause Early Adapor ;-)
But when will it Shipped ?


@Marto : can u do me a favour and add a TP Link 3020 Router to my Order ?

Greetz Glen


Answering all
e-mails and PM about 130 GHs units
The shipping of 130 GHs units will start mid march.
All end of feb 260 ghs units already shipped out

From experience Technobit are not good at adding stuff to orders. I'd recommend ordering a TP-Link off eBay and doing the firmware upgrade yourself.

167  Bitcoin / Mining support / Re: Have I killed my graphic card? on: March 15, 2014, 09:34:38 PM
Hey guys, I went out earlier after just installing windows 8 and setting up a miner for my R9 270X and when I came home, all it shows is the windows 8 activation screen. As in, even if I reboot into linux, it just shows the same static image of the activation screen with a mouse pointer in the middle.

Seems my card is just displaying the last frame it "saw". Is there any way of clearing this and getting it to work again or is it totalled?

Not sure if this is the right forum but any help/adive would be appreciated. Has anyone had this happen to them?

Maybe it's just the case that Windows 8 takes over your PC and stops you installing anything else? Tongue
http://www.pcworld.com/article/2027864/secure-boot-loader-now-available-to-allow-linux-to-work-on-windows-8-pcs.html

What happens if you pull the graphics card out and plug your VGA into the motherboard?

hey marto74, what's the chances of getting something (say.. extra h/w) for the DOA and $500AUD to DHL the damn things back to TechnoBit? Tongue did I mention the lost shares from half a THs of hashing power while I go through this RMA process?

Cheers,
QG

Sometimes DOA can just mean the USB leaks power and your power protected USB hub wont let your PC talk to it.

It's always worth trying it directly plugged into a TP-Link TL-3020 (running the Technobit firmware), bypassing the USB hub, to check if it works. (risky to do this with a PC/Laptop! but it won't break the TP-Link)

If it does work, you can solve it by taping out the ground or +5v connector in the USB cable, then it should work back on the power protected hub.
USB1 hubs/PC ports can cause problems too as they are not fast enough and some power supplies have issues if there is nothing plugged into the 5V line.

170  Bitcoin / Hardware / Re: AntMiner S2 1TH/s Miner (1w/GH/s) on: March 14, 2014, 04:21:02 PM
If you're stuck on 55nm just sell the S1 underclocked and let people build up their 1GH/W hashing power from smaller cheaper units. Roll Eyes

Underclocking the S1 doesn't decrease the production cost.  All it does is decrease the effective $/gh and makes them less appealing.  If buyers are stuck on GH/W then they should underclock the S1 themselves.

You need to underclock the frequency and volts together (to balance H/W errors). But really I'm saying the the new 55nm chips have the same size package so just stick them on the same boards/chassis that everyone knows and loves. It makes no sense to re-design everything into a big silver box. Just sell 100GH/100W units @ 0.5BTC. If someone wants 1TH they can buy 10 of them for 5BTC and you ship it in one big cardboard box. Wink

There is a huge variation but it's in both direction over 5s average, but it evens out, the second number is the true average and it will settle down after a few days running. Set diff to 1 while you're tuning Freq/mV settings. Like other people said, put something on the PSU's 5V line, if you have powering down issues.

173  Bitcoin / Hardware / Re: Where invest my budget to get some profit? on: March 12, 2014, 11:21:07 PM
Don't, mining is not profitable while difficulty rises 50% a month, you'll struggle to get back what you invested.

If you really like the whole Bitcoin idea just buy the coins and speculate on the price movements.

174  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: March 12, 2014, 10:28:56 PM
I'm not sure I understand the complaints about mining farms undermining non-centralization.  That was from the days of mining using Bitcoin-QT, with the CPU both maintaining a current record of the blockchain and mining.  

The point was that there were copies of the entire blockchain on every computer using Bitcoin-QT or bitcoind.  That was what needed to not be centralized.

Our miners do not maintain a blockchain with all the blocks.  The pools do tho and some who solo mine might, don't know.

There are two things you do not understand about decentralizing the mining.

1) It makes it hard for those who hate Bitcoin to close us down.
2) It makes transactions more secure. If a farm/pool has enough share to complete 10 transactions in a row it means you cannot know they didn't cheat until you get 10+ confirmations and the integrity of the blockchain is confirmed by another farm/pool.

You will find the biggest ASIC makers both run the biggest farms and pools. It becomes a conflict of interest. You trust these people with you wealth?

The angle of your solar panels is wrong they should be somewhere between (Summer bias)35-45(Winter bias) degrees.

Did you see the new Bitfury2 chips? 25% more hash and 25% less power. http://www.bitfurystrikesback.com/product/bitfury-55nm-rev2-samples/

Good luck with your project. I'm seriously thinking about a 4kWh grid tie solar to bring down my electricity costs. At 15p/25c kWh it starts to look economical.

It is a complete scam though, if it wasn't for central planners deciding the cost of electricity, solar wouldn't be viable in a free market!
I feel sorry for the poor sods without south facing roofs subsidizing those with them, it's not fair!

HEX16B with Bitfury Rev2 chips




Damn, i knew it. I should just buy the engineering sample chips while they available & send it to you. Now they already out of stock  Cry Cry Cry

Checked this morning with BitFuryStrikesBack and it says "in stock" 32 chip order limit.
I guess someone made a big order and wiped out the stock on the system and they've put it back in.

178  Bitcoin / Hardware / Re: 750 GH/s - 3TH/s Miners from $3565 - www.bitcoinultra.co.uk on: March 12, 2014, 12:25:54 AM
The maths just doesn't add up, the ROI on this unit is just not worth it.

Why not just buy 5 ANT Miners?

5 x 180GH/s = 900GH/s  - That's without over clocking.

Because UK scam electricity is now 15p kWh.

5x 360W = 1800W

1.8kWh x 15p x 24hr x 90days = £583.20 on top of every normal electric bill you pay.

And there's no easy way to cash in your Bitcoins to pay your electric bill because the banks block the bank accounts of anyone who tries to setup an exchange.

Is the problem with bitfury devices only sending in some of their proofs of work fixed? Was there a firmware update or something like that?

Or is it still necessary to set a high difficulty or other tricks?


Yes, I noticed 25GH higher work recently than the past few days. It was something the pool did. I'm back at 700GH.

That is why I'm asking...

Mato would you by any chance compile a windows cgminer... I can't figure it out how to do it... Follow the instructions but it looks like I'm missing something...

https://github.com/ckolivas/cgminer/blob/master/windows-build.txt

Step * Install mingw32

I think I do something wrong hire since I'm missing

Start Icon/keyboard key ==> All Programs ==> MinGW ==> MinGW Shell

in next step... I think instructions are too old and MinGW is now different...

Try this old video tutorial... http://www.youtube.com/watch?v=l9SgoVm16Sw You need a proxy for it to work in windows.
Seriously though use a TP-Link TL-3020 it saves you loads of power don't bother running anything on a PC!
