hi guys, here is 2 hours to the new year! happy new year everyone!

i just released a beta ver fpga code and miner software. speed up to 380Mh/s per board, and power is (looks like) equal as the old one. long pool is supported. and the logic is very robust.
the source will release soon.

10 boards is under test. Grin

Awesome.  I have no doubt that given enough time you will hit 200MH/s per chip.  Was 80%, now it is 90%.

So are you saying it might be possible to push BEYOND 200 MH/s?  If so then even more awesome.

Nice work on getting the hash rate up!

Are you referring to the number of FPGAs?  I haven't seen anybody with 3FPGAs on a board.  I think rph is working on a 4FPGA board, but haven't heard if it is working.  

If you're referring to the grade of the FPGA, the X6500 has 2 -3, but as far as I know they are getting around ~280MH/S for the whole board.  I thought you're using a -3?

no, -2 and -3 refers to the device speed grade. -3 is 15-20% faster than -2 device.

oh ,the opposite.

-2 which i'm using is 15-20% SLOWER than -3 device.
but cheap.

I see.  Even more impressive to get within 10% of ztex w/ a slower speed rated chip.  Very impressive.

sorry guys, today i took some holiday time. the order/ pre-order looks like will delay for some hours.

i received huge numbers of email and PM for order, but the order flow is really not started yet.

notice that i reserve the rights to choice my customers. so it's no need to feel worry about the pre-order.

What do you mean by "Upgrade to 12V/3.33A power adapter : 10$/each."? Am I correct that there's no power adapter included but basically every one with the given specs would do?
edit: forget the first question, I just reread your initial post and found the answer Smiley

Is the dev kit required to use new updates in the mining software (to load new bitstreams)? Or is this only required to create own bitstreams?

It's impressive but I hope these things never get to a price that would cause the main stream to buy them. It would drive the bitcoin price down since they use such little power. Investing in a normal mining rig is not to risky, even if the price dropped to nothing the parts could be sold for a decent return. I would image these would be near worthless outside of mining.

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

It is inevitable but IMHO the switch will be longer paced then from CPU to GPU.  Like you said there is substantial capital risk.  Especially if you bought a lot.  Still I plan to dabble in FGPA in 2012 but it likely will be some time before I have 10GH of FGPA miners to replace my 5970 farm.  

Still on a long enough timeline (say 3+ years) I see FPGA slowly killing off GPU mining.  A re-enactment of the GPU vs CPU battle on a larger timescale.  AMD craptastic (for mining) 7000 series only helps FPGA.  Had they delivered double the performance per watt and per dollar it would have readjusted the comparison metrics for FPGA and made them risky.  Luckily for the OP AMD didn't deliver.

I think it will take longer then that. The power costs are still pretty low on the gpu's. I pay under 3 cents a watt, which is around 6 percent of profits right now. It could play a bigger role if the bitcoin price drops under $2.00 and makes it unprofitable in areas with high power costs. Even then they will still be competing with people like me who can profit unless it drops under $1.00 I think maybe in 7 or more years it could compete, depending on how well bitcoin holds its value.

Electricity costs are 6% of the profits because you are only competing with miners that have cheap electricity like you. FPGAs will allow almost everyone to mine. You can expect a significant difficulty increase during 2012 even if the bitcoin price remains the same.
