this is generate by smartXplorer flow.
actually, it's used for a higher P&R speed. you certainly can run with out this guild file, and turn to smartXplorer, but it cost a lot of time...

no, please do not deduce. i do not have a -3 device, so there is no test under them.

and, 380 to 400 only a 5% difference, it there really necessary drive the FPGAs to such a limiting case?

after the shipment over, i will clear up all the code and put them on github, if any one want to try a higher speed version, just do it. anyway Icarus present is a  warranty invalid product.  

no map need at the first step. just sync and get a NGC file.

a close beta ver bitsteam is already reached that speed (400M average), but looks like not 100% stable on all -2 device.
so ...

do you copy the "sha256_top.ngc" NGC file(first step you got) to the 2nd step "right_with_bigID_and_ZERONonceMod2" folder?

another reason is FPGA mining system has smaller size and heat.
here in Beijing, China, the housing price (flat) is about 4500$/m^2 . (*2~*3 for house).
a 5G GPU mining system can take over 1 room with no difficulty. that means wast your 40,000$(for a 8 m^2 room).
and a same hashing speed FPGA system can easily deploy next to your desk with <300w power consuming.

8 package, 16 Icarus are on the way. delivery with reinforced packaging. all payed buyer's product is on the way.

i will send them to EMS agent tomorrow.

Xiangfu already received the first 3 boards today, we are in the same city.


i'm still thinking...

it looks like my future plan will reduce to 1 FPGA board. and with a daughter - mother architecture.

i agree with you.
that "resistor" infact is a ceramic capacitor. soldered  by hand and looks ugly. because i forgot to reserve a PCB edge for the SMT. 

oh, it looks like this capacitor is touched by some stuff during the transport.
it there any issues except the skew?

and:

i suggest return that board and change that capacitor, i afraid there will be some damage inside that capacitor.

and and:
looks like i must open the package again and do some reinforce to the package...

after i finish present shipment.

ADD@1/12

i finished packing tonight. but a burst work from school made me very busy these days. i hope can send them out tomorrow.

fans are included.

hi, everyone.
2nd batch order/ pre-order now temporary paused. i do my best to ship out all Icarus that already payed.

about 25$

check it here:

http://www.ems.com.cn/serviceguide/zifeichaxun/zi_fei_cha_xun.html

 and you can use them as your own risk under GPL license.

1, unknown.
2,tomorrow begin to prepare, take 2-3 days to finish.
3,yes. with a pc.
4,no use for noob.
5,less than 10.
6,no. depends on where you live, and the package weight.  maybe 20-40$ for one.

ADD:
very sorry, i just contact the local EMS international shipment agency, he sad they will in the "new year holidays" until Jan. 10.
that means i will send first 10 boards to ship 3 days later.
 

ADD: first 10 boards all pass the test (mining for 1 week).
payment start.


i send email to pre-orders. but now i'm really in a email jam. so if you pre-ordered, but not received any payment email, please re-send a remind mail to me. really apologize.

no, will ship buy with a final released core.

i will do it, but now at github is a beta ver bitsteam... my original purpose is that who don't know how to use, then don't use (at this time).
still some small modify is needed. and i may write a guide.

nearly half of the 1st batch buyers are developers, not (fully)for mining.

OK , all updated @ 1st floor.
