It's a 38Ghs machine sold at taobao.com for 1999 CNY, which is around 1BTC now.

that is the cube.  should be out very soon.


 if it is 1btc for 30 gh that is a good price.  it will sell like mad.   cex.io is  .092 for 1gh  that is .92 for 10gh. 

so if you buy from cex.io you pay 2.76btc for 30gh  .  if you buy this at 1 btc that is a lot less.  I want 2 for that price.

1 BTC! I will buy 1 to test myself.

yeaaa, but what about shipping?

yeah I figure it to be more then 1btc for usa buyers. but if it runs 1.25btc or 425 usd shipped to any usa state I would want one.  if it is 1 btc or 340 usd shipped to any usa state I would take 2.

I want one!

That is a really cool looking machine.  I love hardware.

The Aluminum case isn't too bad

whats the power usage?

A quote from the listing

Looking the pictures over, looks to be six boards with 16 chips apiece for a total of 96 chips, the same as three blades. A stock blade runs off 12MHz, with a theoretical limit of 10.752GH so three would run 32.256GH max. The V1 blades had a secondary oscillator at 14.318MHz with a limit of 12.83GH so three would run 38.49GH max. The boards in the Cube also appear to have two installed oscillators.

I'm gonna guess the Cube is 96 of their standard BE100 chips on six boards, running 12MHz primary and 14.318MHz overclocked. Two VRMs on each board, my guess is in one of two configurations. Possibly they run in parallel each powering a bank of 8 with software-selectable voltage output tied to oscillator selection, or if one runs stock 1.05V and one runs 1.20V such that when "high speed" is selected in software it automatically drives the secondary VRM and disables the primary.

If it's the case that they're the same BE100 ASICs present on Blades and USB BEs, then the power consumption is going to be the same as everything else - in the neighborhood of 250W for stock 30GH operation. Using an automotive blade-style fuse could be seen as a convenience for replacements without requiring disassembly, or because it's easier to find 20+A fuses in automotive than standard SMD or tube packaging?

The only question I have presently throwing that power estimate around, is the twin six-pin power connectors. If this is to be used with a standard ATX power supply and twin PCIe power leads, the six-pin connector is only required to supply 75W of power giving this a total intake capacity of 150W.

Looking forward to hearing more official information, and definitely getting my hands on a couple to play with.

better to look at this groupbuy, because https://bitcointalk.org/index.php?topic=233624.1680
There is a upgrade module. 1BTC=7 shares=around 50Ghs. Better than the box. We are getting paid for this groupbuy, but buying the module is at your own risk. Don't blame me if you lose your money.

ffs people haven't learned anything from the usb miners  ???

Shares and hosted mining is lame. For me half the fun is having and playing with the hardware. Actually, pretty much all the fun is having and playing with the hardware - the reason I'm looking into getting one of these boxes is so I can tear it apart and make it work better than anyone expects.

But yeah for people whose primary interest is just buying in and making money, look at that guy's group buy.

nice , thanks. now how to get 50?

you fucking serious? Why don't you look into ragingazn628's history.. It will make you CRINGE!

Are those boxes ready to ship?

I can see you just dying to throw a 16,384 Mhz crystal in one....

Maybe, depends on power handling and cooling ability.

Qouting another member from a different thread:

 
If this is the case then sidehack's usual skills should be able to push one of these to a theoretical limit of 45ghs, with improved power handling also it should not go much more than the 500w.  

Question is with dual pcie for power only, how's it going to do that; as someone else stated, pcie only does 75w per lane.  

Either way a disappointment from them, I was expecting a new product, not the same thing as before in a shinny new box.

Right. My three overclocked blades run about 400W at 44.7GH - not exactly efficient, but it's winter and this house has electric heat so I'd be paying for those watts anyway. With the compactness of the box it's gonna be fun figuring out how to heatsink these better; already got some good ideas and the modularity of the device should make hacking and testing easy.

agreed AM has made enough money off us with this outdated tech....  was expecting much more from them...

I would have rather seem them continue the Erupters and hubs then this. Its not aimed at the beginner

i'll need some solar panels to offset electricity costs after winter... :(

I've been researching solar nonstop for the last week and a half, unfortunately renting a house with landlords who won't budge on installation we're up the creek without a paddle.  Would imagine some company would be working on a more plug'n'play option for folks in condos, townhomes, etc., who cannot necessarily "install" something but can still benefit from the renewable power supply.

PCIE is only limited to 75 in PC aplications. See the 300w BFL single powered by 2x 6pin.

ive been thinking about something like this..... ran into a grid tie converter....  cant afford to go all solar...  but might help keep the bill down to a reasonable level,

I can get them sourced for £427 so that's 1.7BTC at current

Cheers

Double the price :(

Yeah, there are loads of china suppliers selling them, some with power supplies that can provide the correct overclock, but for the price I would wait until much cheaper. Same chips just dressed up in a different box plus still supporting the OLD protocol, clearly no improvement has been made.

at least they overclock....

OLD protocol = getwork?

I'm intrigued about the USB interface, if they're coded to work with cgminer like the USB BEs or what needs to be done there.

yes getwork is the old protocol  port 8332

I wish the gid tie inverters were sold at Home Depot, I'm about to do the same.  I can only find them online...

More cards & Less chips per card = more crystals required = more expensive to do the mods.

these are set up like the version 1 blades, low speed and high speed,   each board already has 2 oscillators

Agree, but it's been proven that a even higher frequency crystal can be used to push the chips further while maintaining stability.

 how much life are you robbing from the devices by making them go faster than originally designed for?  i know it would instantly void the warranty...  id rather have a year at 100ghs than a month at 140ghs

Actually, sidehack usually uses high end products and cleans up the voltage variations also, probably even extends the life of the product even with the overclock.

still won't roi

And will still outsell and get out of stock ;-) That's the way it works in Bitcoin Mining (or mostly for Asicminer)

im might be a big shock.... but have you ever heard of a hobbyist miner?   Someone that does it for curiosity?  Fun?  The learning experience?  Most College Educations wont ROI.... I dont see a lack of customers for them.

This cube can hardly pay themselves back. Don't buy if you want to make profit. Buy BTC instead.
