Topic: DIY FPGA Mining rig for any algorithm with fast ROI - page 16. (Read 99494 times)

Xilinx does thermal testing on all of their FPGAs. I was way short on the UltraScale+ parts actually. They ran it for a combined 170 years across multiple devices at junction temperature of 125 deg C without any failures.

When I say other components are more likely to fail, I am referring to things like the power supply, capacitors, and other discrete components or ICs.

There was no evidence of their other stealth miners either besides the hash increase.

Bitmain uses some smaller Xilinx FPGA for their management boards for their ASIC miners. There is no evidence yet there would be directly making FPGA miners.
All design details of VCU1525 including BOM was public on Xilinx website until recently. So anybody could take the BOM list and try to buy all the stocks of some components.

This whole thread is about the VCU and subsequent BCU group buy. Zetheron.com has details of the various mods. Buying a stock VCU will be a challenge, going direct is pretty much your only hope, and that'll take over a month at least. BCUs are/were on mineority.io.

Odds Xilinx partnered w/Bitmain and would do a pre-emptive release of ther FPGA hardware before this one?

Odds Bitmain got a hold of some of these boards, figured what parts to "hog" and bought the bulk of the stock?

Where is the best place to buy a Xilinx VCU1525? And how much modification does it need to work?

If there are better options now, I reckon we would all like to know...

Many people (including me) received their VCU1525 directly from Xilinx official distributors. As whitefire mentioned in the beginning, this card needs some modding, that's one of the reasons the group buy for modified BCU1525 started. So many people are already mining on these cards and using bitstreams from 2 distinct developers (whitefire/zetheron and digitalcruncher).

That more profitable bitstream should be available by 15.9. As whitefire mentioned, many changes in the coins happeneded in the last few months. He had to stop developments of some half-finished bitstreams due to either coins now having zero value or changing their mining algos. That also adds to the delays in bitstream publication.

Whitefire "advertised" (approximated) $20-$50 per day, but of course in the market conditions of that time (price, difficulty, algos). I guess he doesn't have a crystal ball to know how that all would be in 3 months.

Also since you guys don’t deal with individual consumers directly and only sell to businesses that in turn sell to consumers a bulk order would be for what 1000 units at least?  Around the ballpark of about $5 million or so.  So you can either gripe about a $5k-6k card where they are making let’s say even $1k a pop and as a retailer have every right to do so or pony up $5 million to buy at bulk order price and have all 1k units.  Makes sense to me. 

If you got a bulk price of $5000 or less that would have been for a CVP-9, not a CVP-13.  The VU13P is WAY more expensive than a VU9P.

The difficulty on equihash doesn't seem to be rising as fast as Dash. Anyway, like I said, I will never buy from bitmain

No indeed. I bought an early D3, and we all know how that worked out. Very clever, Mr Wu, very clever, but I'm not playing anymore.

Actually your dead wrong.  They have to release these. Decentralization is in jeopardy.  The whole crypto concept is in jeopardy!  They were selfishly mining away themselves till they were threatened by bitmain asics.  Now they dumping their bags on customers.  Most likely collecting interest off that pre order money to boot.  This is a clusterfuck if ever there was one.  FPGA needs to take it on the chin and realize asics are here now.  Game over

With zen not forking, it looks like the z9 has so more time to go before becoming uninteresting but personaly I will never buy from bitmain.

Nice one!  

As a side note, interesting that the more reasonable company reps are with people, the more aggressive they get. As a contrast, the (important to note: completely unrelated) Dwarfminer scam thread barely saw this much angst, and that was a bust from the off.

Finally, while there might be delays on this group buy, what are the other obvious options for a keen miner? Buy new Nvidias? Sell all GPUs, buy....Biakal/BM asics? None of these look particularly tempting from here anyway...

Zinger !!!

If you're going to use federal law to threaten someone, it helps to not use documents from 2001 that are no longer accurate.  The rules have since changed to allow a business to not provide a revised shipping date so long as they have a reasonable basis for doing so:

Try harder next time.

Makes a lot more sense for his FUD and “senseless” anger (pun intended).  I can see why he is pissed off and angry.  He is a miner and makes his living off of mining and at the current market in the crypto space probably either running at a loss or barely profiting so he is salty either way.  Saw this “BCU1525” as the answer to his woes like a lot of other miners including myself, but didn’t have a backup plan in case something like this was inevitably was going to happen since this is a first time for everyone including the good people at SQRL LABS and Mineority (thanks you guys!).  You really should heed your own advice and “own up to your own mistakes” in 1. Buying said equipment from a company you hardly know or think they are doing unethical or deceiving practices like taking crypto for payment and not forwarding Xilinx payment (man’s got great imagination) 2. Nobody has pity or sympathy for you having to sell gpu’s to buy or afford the fpga’s.  Shouldn’t be risking or selling off equipment you use to make a living if you couldn’t afford to be without it for said unknown amount of time.  You knew the risks and you took them anyways.  I don’t believe SQRL or Mineority or anyone for that matter FORCED or THREATENED you in anyway to buy their products (hopefully Dave @SQRL didn’t send like evil squirrels and threatened to take your nuts or acorns, lol) besides the point.  In your own words “OWN YOUR MISTAKE, DON’T BLAME SHIFT”, and most importantly TAKE IT ON THE CHIN LIKE A REAL MAN, myself and several hundreds of other people just like you probably knew better and “had a backup plan” like you mentioned in case something like this would happen.

Sorry for the rant guys, I just hate how people like this feel they are the only ones in this situation and nobody else is being affected from this but themselves, but as civil and supporting community members in the space we appreciate the overall bigger picture SQRL LABS and other affiliated parties are bringing to the space that they didn’t have to, no thanks to assholes like COINKING7 and other trolls!

Well said and agreed.

This is actually quite funny and assuming.  Who the hell is COINKING7?!?!

I'm going to bed. You can wait til tomorrow Senseless. Nice handle by the way. lol
