limit to cryptonight :
there are 2160BRAM+960URAM in XCVU9P,you can use 38MB in big ram cascade mode,that is 19 core
each cryptonight  hash need 1M memory read and write cycles.
if you remove all pipeline,you may get 100H @100MHz per core.
if you all pipeline to improve fmax,you will get slower hashrate.
it maybe very hard to run 100MHz with no pipeline.
assume it is 100MHz,19CORE, the max hashrate is 1900H/s.
if using extern DDR4,the limit is bandwidth,36MB per hash,each DDR4-2400 may get 533H/s,
but the cryptonight  random access rate is 16byte ,memory random access rate is 128byte , the valid efficiency is 1/8
each DDR4-2400 may can get 66.6H/s,and 4 DDR4 you get 266H/s

the max theoretical cryptonight hashrate is 1900+266=2166 H/s
Don't dream to get 22KH/s

You couldnt really say "beat to death as mining hardware" when your creating it for that purpose. If its obeying the purpose, a 90-day warranty wouldnt be within the reasonable standard. There are many factors when coming up with a warranty, and for this product being $3000+ and being used for its intended use to break within 1 year, would most likely end in a lawsuit with your company if someone wanted to. There is an implied warranty, and you will be held accountable for implied warranties if the product cannot do what its built to do for atleast 1+ years. This is why you see long warranties in the computer sector.

I know there are issues in the United States with 90 day warranties too, one of the main reason you couldnt order Mining Cards from distributors and major brands/stores.

Perfect, I have the 5 cards on 1x to 16x risers of course powered via sata cables for each riser card.  Look forward to learning something new.  Thanks!

Oh wait, one more dumb question.  My MB has only 2x PCIe 3.0x16 and 4x PCIe 2.0x1.  The risers are 1x to 16x, will that be ok to run 5 FPGA's this way or would it cause stability issues in your opinion.  Thank you again.

Senseless, there is something else.

Sorry,its 5 AM and I am not awake enough to search for the english one...

In English: its enough that you clearly state /write/ on the website that the  good you are selling have  a maximum of 90 days continuos use since the day of delivery.
if its clearly written/stated on the order, no consumer can invoke the standard warranty law after that period in the country listed above.

If you need help/ detail, I am on Discord and on your discord server as well.
And I will take one when will be available

BTW:  Will my current rig running a AMD Ryzen 3 CPU and ASRock 350Pro 4 MB be compatible with the cards?  It's currently powering 5 1080ti with a EVGA 1600T2 via a data center grade PSU connected to a 40amp line.  Will there be any other components needed besides what I already have?  Thank you for answering my questions and apologoes in advanced if it was answered before.  I read through the thread but couldn't figure out if it would have issues with the AMD setup.

Cheers

Ok so lyra2z is hashing at 20 Mh/s. A single RX 580 hashes at 3.2 Mh/s. A single Vega64 hashes over 6 Mh/s.
You therefore need 6x RX 580 for one FPGA. But you can get 6x RX 580 probably for around half the price of a single FPGA.

It is as I thought it would be. They are not so terribly powerfull, but they do have a loooot better hash per W ratio. They are expensive, so basically for those with deep pockets. On the other hand as this is still a fairly new field being born again from the ashes, this means there will be some birthing problems etc...In the end I would still bet on GPUs simply because they are proven 100 times over and flexible.

You all have to also bear in mind theat GPUs today are basically 3-4 year old arhitecture. AMD for instance is going on with the same artitecture simply because they did not need to get out anything new. I am sure they (and NVIDIA) have much more powerfull GPUs already prepared but are holding back. So it can as well happen you pay costly for FPGAs just to have both GPU manufacturers release relly powefull cards at the end of the year for instance. And because of mass production they will always be cheaper.

I am definitely going to wait to see how all this plays out

EDIT:

And I just read about 90 days of waranty. Is this correct? I get 90 days of warranty for a 3K$ worth piece of tech. Em ok. Meanwhile I get years of warranty for GPUs. Man if that thing dies after 6 months thats gonna be really bad.

I don't try to put anyone down here don't get me wrong. You seem legit, I am just that voice of doubt in the back of peoples heads Although I am sure most will ignore me lol.

So the sales has ended or has not started? I see everything is sold out.

Indeed Europe has a minimum of 2 years

What do you mean EU:EU?  Like selling from an establishment or an office in EU? In EU:EU case  is always advantagesous for a buyer  ( and it probably would not sound  as advantageous for the seller though), cause  if a manufacturer does not provide 2 yr warranty,  the seller will have to, regardless of the manufacturer)).

On the other hand, from buyers perspective it may make sense to get in touch with Xilinx EU distributors, there are some sales contacts in EU  I remember(Italy and France). Those would have to provide 2 yr warranty.
Indeed. I would be really upset even if a $500 GPU fails, not to mention a $3.5K-5K card.

@senseless, does this 90 day warranty apply to modified FPGAs only (due to modification) or to out-of-the box  (unmodified) ones as well?

I know there are issues in the United States with 90 day warranties too, one of the main reason you couldnt order Mining Cards from distributors and major brands/stores.
