The three boards I am going to initially support are the Nexys Video (XC7A200T $490), Avnet AES-KU040-DB-G (Kintex Ultrascale+ $975), and VCU1525 (Virtex VU9P $3995). I will start a thread soon and list which algorithms will be released for each board (the Virtex can run all the algorithms, the Kintex can run most, the Nexys can only run a few).

My implementations are 100% unrolled pipelines running at one clock cycle per stage. The ROI on the Kintex and Virtex boards range from 50-150 days based on the algorithm, in today's bear market with 1-2 year ROI's on GPU's. If the market rises back to Dec/2017 levels, ROI would be ridiculously short.

There's also a dead end in this.... All those dev boards are produced in china! Shitmain and other fat wallets will just HIGHJACK this and the loop will just start cycle again.

As I've said before, I'm willing to design the PCB for an FPGA miner if someone else writes the HDL. There could be some cost savings by stripping out a lot of the extra crap that is on the usual FPGA demo/devkit board as well as more flexibility with the choice of FPGA. It probably wouldn't be smart to stray too far afield from the devkit FPGA choices, however, as that will make debugging a lot more difficult. That said, there's no reason to throw in the towel just because the devkit boards are made in China. Bitmain can't get its way on everything, you know.

What type are slot requirements for those cards would be if exploited for mining purpose? I thinking about compiling an Octominer mobo on linux snaphot distro with miners software ... could be a great bundle set... can't wait for you to open up a different discussion about this! Wink
