will be back up later

[Xer0]

pen the pdf files in a sandbox to be sure

[Cheshyr]

Is this new?  The website goes to a godaddy parking page.  The Github has has some preliminary data though. It looks interesting, if we can get more information on it's status and timeline.

[miter_myles]

No HDMI port?  wtf...

[fasmax]

Avalon hardware level protocol match.

Where can we see the address map for this chip?

EDIT: Never mind found what I was looking for.

 

[webjoe]

Are you only selling the chips?  Or do you intend to sell a full mining system. 

[kr105]

Looks promising, but we need info about if you plan to sell the chips or full systems, tentative release date and maybe fix your website lol

Looks promising, but we need info about if you plan to sell the chips or full systems, tentative release date and maybe fix your website lol

there is conference on 8th dec in Beijing for launch where you can pick up raw chips & development board. other regions will be added later

for now there is no vacancy for official agents/resellers outside china, so only need to check back on the website for latest news.

chips will be released over time, and slowly gen2 will be on market, with greater hashpower, but to avoid the 51% attack on litecoin network, release is staggered.

Hrm. 

http://www.gridseed.com/ appears to work, even though the initial link does not.  The website currently consists of the words Gridseed and a shiny little javascript glitter pattern.

Some other info I dug up:

While experienced a few months ago notorious Beihong times wild , with the recent upsurge currency, futures and pre-sale everywhere, chips and mining machinery industry is currently true and false news sky fly. Regardless, the mining machine is a high-risk investment, please self-assess their risk tolerance, and saw the loss of cool soaring currency, it is very dangerous.

Recently it was fake Gridseed and Gridchip in online sales on behalf of the mining machine, to remind the miners: 
1, Gridseed not yet authorized any company or individual selling any mining machine based GC3355 product. 
2, Gridseed's official website is http://www.gridseed.com/ , in addition there is no other website. 
3, after the mining machine Gridseed official product sales, will announce sales channels, price, dealer information, etc. on the official website. Not released official online sales channels all fake. 
4, Gridseed mining machine products are in stock, after the customer orders 24 hours to pay the full amount, confirmed after payment is received within 3 days of delivery. Sell ​​futures were all fake. 
5, for any impersonator, Gridseed right to further pursue its legal responsibility reservations. Gridseed

first sale of USB mining machine is four or five chips, depending on the final product of power consumption and heat dissipation. 
Citie conducted USB mining machine price quiz, rules are as follows: 
1, in this post Reply Guess price elsewhere reply invalid format roughly as follows: 4 chip USB mining machine: XXXX million 5-chip USB mining machine: XXXX yuan 
2, each Only a valid ID quiz price, if multiple quiz , follow the results of the first quiz prevail. If the first quiz replies were edited, this ID is invalid 
3, after the final price of the product officially announced Guess price and the final price which is closest ID, this ID to get a reward USB mining machines. If there is more than one ID, like the closeness, then who should reply who gets the mining machine 
4, quiz End Time: Beijing at 8:00 on December 4, 2013 (ie within 72 hours)

So, it looks real, albeit a little difficult to plan for currently.

Any one know more about this chip?

Any one know more about this chip?

specs are here

https://github.com/gridseed/gc3355-doc/blob/master/GC3355_DataSheet.pdf

And holy shit, it claims to do 59.6 KH/s while using 0.44 W

This is 0.00738 W/KH/s versus 0.300 W/KH/s for a GPU -- a 40.7 fold increase in efficiency.  This is about the same increase in efficiency as compared to BTC when ASICMINER first introduced its chips; I'm curious to see how they did it.

[Cheshyr]

First chips are getting into developer hands today.

Scheduled at 10:00 on December 8, 2013, in West Street, Haidian, Beijing, 70 3W coffee (Haidian Book City, south of the membership across the sea floor), held Gridchip GC3355 chip product launches and mining machines. In addition to the chip and mine-site machine product launches, and BTC, LTC demonstration outside mining, but also on-site sales of 50 sets of single-chip development board and a few chips.

Development board: each 500 yuan 
chip: 400 yuan per piece, per pack of 1600 yuan four chips 

This price is only preliminary offers developers, not as a formal reference to the product price. Each person can purchase two development boards, chip purchase of two packs per person.

$65 a chip for the early pieces.

Very interesting !

LTC & BTC chips...i buy ! 

[Vagnavs]

just chips or a miner?

[tacotime]

Chips and dev boards for now

Pictures confirm the release event and functionality.  One person was able to get a single chip to hash at 84 KH/s.

[papamoi]

hi

so who is producing it?

This could be a game changer.. at least as hardware is concerned.

getting very interesting.
