@whitefire990

thanks for your effort on the FPGA,

i wanted to find out if you have support for Decred ? is that something that is available right now and do you have any stats ? im planing to build a FPGA miner and would be great to get some stats.

thanks

Please add Linux HOWTO as well...

(both FTDI D2XX drivers and Vivado Lab Edition are available for Linux)

Disclaimer: Any forward looking statements are my own and should not be taken as economic advice; only my own personal opinion and what I'm basing my own personal decisions on.

This current batch size of units (the total numbers of units that will come online between now and december) is about 20% of your total number. Even if there are secret groups who are purchasing, the saturation point isn't going to be hit for awhile. I believe the numbers will be closer to $40/day for the next 6-8 months barring some major unforeseen influence or unanticipated situation.

Hi Whitefire,
will there be a more specific "how to" for the Hardware-Optimizations, wich have to be done to the Boards, to get full speed?

This is pretty accurate which is why on the website it says that for longer term profit projections, a value of $20-$30 USD/day, per card, is a realistic estimate.

You never got an answer in that - these are VCU1525s, not a custom design. Just specialized crypto pricing and some options to preconfigured voltage levels.

Thank you for your work and also the no BS, honest assessment.

IMHO, there is an error in your working when you assume that a 50% increase in hash-rate will not change profits much. A 50% increase will decrease overall profitability by 33% per hash. So the estimate on Tribus at $41 per card will actually be $28.

Also in your working I think you have split the profit half-way between DNR (33) and KEYCO(46). Whereas their network hash-rate is 439 MH/S and 113 MH/s respectively, and hence the actual projection should $36, further adjusted down by 33% to $24.

To me its  clear the once mainstream mining oriented FPGA card are available, that will be the future as regards to non-ASIC space.

Hi all,

Sorry I haven't had time to read this thread, I have been working like nuts trying to deliver as promised.

The Keccak-24core/708MHz (17GH/s) bitstream burns 306A and will run on an unmodified VCU1525 for approximately 10 seconds.  To run it continuously requires extensive modifications as described here:
http://zetheron.com/index.php/hardware-modifications/

The Keccak bitstream is now posted live on the website:
http://zetheron.com/index.php/downloads/

Also, there is an interesting table where I calculated how many FPGA's each algorithm can support:
http://zetheron.com/index.php/fpga-performance-profit/

So based on the current market, FPGA-friendly algorithms can support 25,000 FPGA's.

You need proper cooling with these FPGA VCU1525 boards. I prefer the passive version cards placed in a server chassis in a data center environment. I do not think that you can properly cool the active version cards without voiding the warranty, something to think about.

Edit: Assuming maximum throughput while pushing the cards hard.

Gonna watch this thread for sure

Whats the discord channel?

I see a couple of updates on discord.

Yes, may/30 was promised as released date, But
you forgot to post an image:

LOL

still waiting for the miner software...

30th May is the date of release ?

Forget lyra2z, mtp(new algo) soon.

This thread has 44 pages now and you(fpga devs) not provided any proof, just theory.
You(fpga devs) say : go, buy fpga and later we maybe implement and maybe release some bitstreams.

I ask again : What are you going to mine with this fpga?

Let's sum up this discussion

Keccak - will work, low profit
Tribus - will work, low profit due to low network hashrate
Phi1612 - will work, forget it, devs changing algo due to anti-fpga and anti-asic policy
Skunkhash - will work, low profit due to low network hashrate
x17 - will work with 2 FPGA, need a verilog masochist, profit will be destroyed with 450x fpga
x16r - most likely will not work, or skip hard blocks at hashing,  need a verilog masochist
x16s - will work with 2 FPGA, need a verilog masochist
lyra2z - will work, forget it, devs changing algo due to anti-fpga and anti-asic policy
lyra2v2 - will work, low profit, asic soon
lyra2 - will work, low profit, low network hashrate
ethash - will work with ddr4 ram, low profit
equihash  - will work with ddr4 ram, low profit
cn-7, cn-light, etc - will work, low profit
Xevan - will work with 4 FPGA, need a verilog masochist, low profit due to low network hashrate
bitcore - I think, it will fit, and work with good hashrate(600MH), but profit will be destroyed due to low network hashrate
nist5, neoscrypt - I did not investigate, possible candidates for fpga. |

What algorithms have I forgotten?

After follow this thread for a few days, I took a look at all algorithms I could find. I reach the same conclusion as above. There will be limited choices for our FPGAs.

Besides, the cost recovery period will be double/tripled when all these FPGAs rush into the market. This is like the Bitmain asics. 3-month payback period when you order them, 6-month when you got them, and you need actually mine with them for 2 years to get back all the cost in the end.

I have to say WOW, so cool.
New miner since last year, and well, ive been hooked.
this is worth getting into.

even if only 1 card setup...

Did Whitefire ever post the software? I've been waiting to see the community test run these for a while before pulling the trigger.

You *can* read 50+ pages but you *won't*. So the answers are: no assurance, no proof. Otherwise read this (and more), find other places people are talking about this and judge for yourself. Or watch and wait.

i m waiting for the fpga miner to test my fpga
