DIY FPGA Mining rig for any algorithm with fast ROI

[Grumo]

fpga now worst than asic.

already became nice doorstepper ! 

How do you define doorstepper? Something with long ROI, or something which cannot earn at least for its electricity?
VCUs electricity cost is still under 20% of earned amount for all the already released algos (and the more profitable algos are only going to come).

something with a so huge long roi that now the problem changed from paying the electricity to a new one where you will never see your spent money back

But difficulty is only ever going to go up as newer and better hardware is continuously coming along, which means that short ROI always turns into long ROI, and long ROI turns into a never ROI.

You forget ROI's can change dramatically with price of coin.  Never know in that 2 year ROI BTC shoots back up to 20k.

Keccak (Smartcash, Maxcoin): 136GH/s (17GH/s per card x eight) ($160/day at Apr-30 prices)
Tribus (Denarius, Virtus): 16.8GH/s (2.1GH/s per card x eight) ($304/day at Apr-30 prices)
Phi1612 (Luxcoin, Folm): 5.2GH/s (650MH/s per card x eight) ($456/day at Apr-30 prices)
Skunhash (Various coins): 10.4GH/s (1.3GH/s per card x eight) ($261/day at Apr-30 prices)


I wonder what the profits are today. 

Divide all by around 5

Yup.... so ~$5 profit per card. ROI? Maybe 3 years.

This is with the worst algorithm possible.
Other algorithm should be far more profitable

"Should be". When it materializes. Except the size of the coins based on those algorithms makes them a relatively risky proposition.
I had high hopes for this project purely for mining regularly forking cryptonight, but I guess that's far too lucrative to share.

Any progress on artix 7  video boards?

Reading FPGA threads for months ... Watching people brick their 3K FPGA ... Not even close to ready for mainstream ... Check back next year

Will the bcu owners need to get the DC1613A dongle for hash boost like the vcu's?

Latest information on Discord is that DC1613A is not needed for BCU.

They have received a go from xilinx to control the voltage via the application ?

Yup via the BMC

Ok thats nice, thank you for you replies.

I'm here on site doing some testing on the boards. I've never had access to so many. Running through and trying to get an understanding of what median chip quality expectations should be. We finished testing around 600-800 this week but some still have a couple more hops they need to make before the end up at shipping.

^ testing 80 boards (16x boards per system 5 systems -- The 16x boards courtesy of https://blackbox.cat/ )

and a screen shot..



...

So far, results of this 80.. They've been running over an hour at 0.85v with a 0.45 multiplier (36-37Mh/s lyra2z) and not a single one has had a bad share (note: hashrate's dont match and there are some pool side rejects. but as far as shares invalid due to fpga misscalculation there are none). Time to move the multi up to 0.46

Cool, my last information was that they were waiting for the "OK" from Xilinx... Great news

Xilinx Alveo boards, just launched, looks like they can take in a lot faster memory bandwidth.  Ideal for memory hard coins.

Alveo has no more memory bandwidth than BCU1525, both have 4 DDR4 DIMMs, not sure what you're looking at.

What is BMC?  Is this an application from xilinx outside vivado?

Need special cable for that?  Accessible through which software?

to op, your website only has  0xbtc and nexus available for download.  where do we get these bitstreams?
