I asked for it to be moved to alt coins. so right now cn7 is going to be forked and in theory you gear will drop 4x of its speed. you are asking 25000 for it. my guess is you saw the fork coming and want to move this out asap. Since it is the developers of monero that say they will hurt fpgas 4x not me do you have a plan if this happens? The actual devs explain it much better: https://github.com/monero-project/monero/pull/4218" @SChernykh Contributor SChernykh commented 24 days ago New ASICs will also be many times slower because of the nature of these changes. @SChernykh Fixed armv7 build ed62058 @SChernykh Contributor SChernykh commented 24 days ago Well, that depends on ASIC implementation. We don't know for sure how their internals work. But according to a lot of scientific papers about hardware implementations of division and square root - yes, looks like 16x times slower." and "@MoneroCrusher MoneroCrusher commented 23 days ago So practically & effectively this makes FPGAs 4x slower, making them much worse in terms of $/hash (see Xilinx FPGA, 22 kH/s CN7 for 4-5k$) than GPUs and ASICs 16x slower still being better than GPUs in terms of production cost/hash but they'll be useless within a couple months and not break even. So this makes GPUs & CPUs the best thing to mine with, if Monero keeps the strict 6 months fork schedule. Is this correct? @SChernykh Contributor SChernykh commented 23 days ago Yes, it's correct. At least 4 times slowdown compared to Cryptonight v1 for all kinds of ASIC/FPGA." Me below so even if asics are made they will be 16x slower and fpga's once programmed will be 4x slower these are the actual developers words not mine So if they are correct monero should have legs here it could be your gear loses a ton of value. this was lifted from my alt coin thread. https://bitcointalk.org/index.php?topic=3843565.msg44771016#msg44771016

WOW , OK. I will respond to your concerns in order.
"so, right now c7 is going to be forked and in theory your gear will drop to 4x of its speed. You are askinf 25000 for it."
I have heard that Monero will be forking in the future. Are you suggesting that we should just hash on it for ourselves until if/when fork occurs. Or should we release it and let people mine on it for a month or so until fork. Right now there are 3 non-money making bitstream algos out there for the vcu1525..... that I can see. If/when monero forks. Our dev will have a look at it and see what it would take to write the new bitstream for it. You suggest our rig will not be as valuable if C7 is forked. You do know that this is not a 4 card cryptonight only rig?...right? It will be able to hash almost all of them where it makes sense. The C7 algo is "OUR" first bitstream with more to follow. Yes, we are asking 25000 for a turn key ready to mine 4 card rig with all mods done.
"My guess is you saw the fork coming and want to move this out"
Really? We just finished writing it and it is still being tested at this moment. We can't just go down to BITSTREAMS R US and buy any Algo we want. We are starting on a different algo next week and another one after that. Not to mention all the bitstreams that will be available from lots of other Devs. I guess I don't follow the logic on this. This Rig was not built to be a Cryptonight v7 only rig. The idea would be laughable.
So....Now that I have explained it. How many rigs can I put you down for brother!!!!

I don’t see any value in this. 4x BCU1525 (available now) plus other parts will cost you at max $16000. So this has a cost $9000 added on top just for “turn-key” solution?

I challenge you to build this rig for $16000. Put it in a server case run it at room temp and not melt your cards. A lot of work went into being able to cram 4 of these into a case and keep the temps down. lots of trial and error. We had to get very creative with our cooling solutions to keep the size down and spent a bunch of money. Sure were going to make a profit. But it is not the obscene amount you seem to think it is. Oh, and these are not BCU1525's. That descriptor belongs to another company.

Please forgive the skeptics here, but there’s been too many promises that haven’t been kept.
A couple of questions... Does going to 32gb ram improve hashing performance? Or would it be used for future algos?
How did you arrive at the 60 day ROI number?
Thanks

Let me put this here for you brother: your box currently does CNv1 only. XMR is forking in two days to a new version of the algo (CNv2) that is going to be 4 times slower for FPGAs.
Not OP advocate, but FPGA can be reprogrammed and these changes are not a problem to be implemented in FPGA the fact that the devs are putting the FPGAs in the same bag as ASICs makes me question their statement and its pure PR but again time will proof the only thing i can think of they are increasing the "space" requirement for the FPGA to implement the algo not the speed.

Correct. But OP claims 60 days ROI. That's a profitability metric. From that moment on he's leaning out the window and he's gotta back up his claim to potential buyers.

Interface PCI-E, USB Power 75W PCI-E + 150W 8-Pin AUX
In the photo I see that you use the USB ports as the ports of PCI-e free.
USB 2 0 - 5V 500mA or 2.5 for each port. USB 3.0 is 5V 900ma, or 4.5 W per port.
Why use a 1600 watt power supply for this configuration?
Will the USB interface be suitable for other algorithms?
What is in the M2 port?

Is there an easy introduction to FPGAs? Even as a hobby could one "bread board" together some old gear and get it to hash equihash BTG? What are the requirements to learn this hobby the least amount of money and is more geared toward learning FPGAs? Like these older links below: https://github.com/progranism/Open-Source-FPGA-Bitcoin-Miner

Hello will answer your questions as it follows Q1. In the photo I see that you use the USB ports as the ports of PCI-e free. A1. Correct they are controlled by usb not pcie Q2. Why use a 1600 watt power supply for this configuration? A2. depends on bitstream but each card can max out to 320 watts each x 4 + mobo, ram, hd, fans (making sure we have room for all above to work if is in full load) Q3. Will the USB interface be suitable for other algorithms? A3. Yes depends what bitstream you use Q4. What is in the M2 port? A4. none, we have M.2 to Pcie will be removed later time

The power may come from 3 sources: PCIe x16 75 W 6-pin 75W 8-pin 150W
Thus, the maximum power consumption of the graphics card with 1 8-pin connector and 1 6-pin connector can reach the following values: 75+150+75 = 300W How will you feed up to 320 watts through the 8 pin connector on the USB interface? The problem is not the connectors and not in the specification. The wires of the power supply are designed for a maximum load of 250-300 watts. But they are not able to work under such loads all the time. The wires will heat up and melt, and this can cause a fire. Many newcomers burned their farms because of ignorance of this.
If the FPGA consumes more than 150 watts, the USB interface is dangerous for it.
