Yeah, you've solicited at fiverr or mturk.

You can't fight bullshit with bullshit. You sound like one of those people that would say that they "hired a dentist" when they go for the tooth cleaning.

The anger that comes through your posts is the same of the anger of the compulsive gamblers, that know that they have problem but cannot deal with it. You get the rush from buying the proverbial "pig in a poke" or "cat in a bag", but just can't admit that to yourself. All the rationalizations you are posting are just for your own consumption, to convince yourself that you don't have a problem. I used to work in the entertainment and "gaming" (polite world for regulated gambling that they use for themselves), I've seen the type at many trade shows.

Quoting the rest for posterity:

There are at least 3, maybe 4 independent FPGA devs in this post who are backing up the numbers of the original posts as reasonable or similar to our own. You may be fair to say you haven’t personally witnessed the evidence, but it is silly to insinuate that because you don’t know how to develop for FPGAs the performance is nonsense is a bit of a stretch.

At the end of the day mining is a competition, and most of us truly competing are not going to show our hands just to satisfy pundits.

It's all nonsense. There is no evidence to prove the hashrate and power consumption.

I think they already mining Ravencoin with fpga.

Don't be, I wasted all my profits flying all over the world trying to raise $5M to build out a huge FPGA mine. All the investors thought it was too good to be true and did not believe that I was mining on AWS. They kept saying "why isn't anyone else doing this", "I love the idea! come see me!", "I want to introduce you to my friend! They're ready to invest! You just need to go see them!".   -- Hey, at least I got to see india, china, hong kong, switzerland, germany, france . Definitely never going to fly anywhere to meet an investor again though.

After seeing posts saying someone fried an AWS F1 board with 300A, and that now there is a 150W limit but it is only a warning, I did a little searching and found that it appears AWS F1 limits your core power (Vccint) to 85W, which would be 100A at 0.85V.  They say they may/will shut you down (gate your clocks) if you exceed this, see https://github.com/aws/aws-fpga/blob/master/hdk/docs/afi_power.md

Also, someone suggested that since the power supplies are current limited, you could just raise the voltage to lower the current, unfortunately this is not how these chips work.  They basically take the same amount of current to do a given job, regardless of voltage.  So the lower the voltage, the lower the power.  This is why chip makers keep trying to run at lower and lower voltages, since it saves power.  

There is another power consideration in all these latest generation chips as well, which is static power (as opposed to dynamic), which is due to leakage in the transistors.  While dynamic power is linear with voltage, static power (leakage) is non-linear, going up as the square of voltage.  It also increases dramatically with temperature.  Static power in general has nothing to do with how much work is being done, hence the name "static".

Note that raising voltage may make you be able to run faster, but faster means yet more power, since dynamic power is highly dependent on clock rate.  You can run certain VU9Ps at 0.72V instead of 0.85V and this will certainly lower your power BUT it also kills your performance by 20-30%.  You can also run certain VU9Ps at 0.9V and get higher performance, with the associated higher power.  Of course the chip vendors charge a premium for these special devices over the standard ones.

So, determining the optimal combination of FPGA size, core voltage, and clock rate is not such a simple task.  As mentioned, we are working with the OP on this.

Wrong link ?


Sorry.
Looks like something went wrong on our end.

Head back to Steemit homepage.

Hey,

There is a problem in this line   if you you will see that the folder that you expanded from the tar file is actually named bminer-v5.3.0-e337b9a (could be something else by the time you read this, so check what you download and expand.

The correct command at the time of writing is  .

I have an updated tutorial and will be adding how to add a cpu miner to smos here.  https://steemit.com/@greerso . If I overlooked something in the rules about posting that kind of link here I would be happy to remove it and just paste the content here.  IMO a link to the source material that I may update is more useful.

Hey mate,

I followed your guide and I ended up here https://imgur.com/NCdp0Wt

am I doing something wrong?

Thank you for help :-)
