19861  Alternate cryptocurrencies / Mining (Altcoins) / Re: Exploring the Threadripper 2 and its mining capabilities on: June 11, 2018, 02:34:11 AM
I am keenly interested in upgrading to a Threadripper 2 for my main desktop, so I'm watching for specifications and pricing very closely. I almost upgraded to a Threadripper 1 setup last summer, but the high RAM prices put me off at the time. Sadly RAM is even more expensive now, but depending on final specs/prices I may go for one.  I don't think I would buy it just to mine, but I sure would mine with it when I'm not using it for other things.  I expect it could pay for itself in a year easily that way.

I guess philipma's electricity cost is cheap but how do normal people figure CPU mining with these threadripper is profitable? It seems to consume much more electricity compared to GPUs. As far as i remember the 1900x threadripper mines 1k h/s cryptonight while cosuming above 200 watts. Seems like you can't compare that to a Vega56 that can do 1.8k h/s while only consuming 160-180 watts.










rig is fully roi'd

edit  I check rig

here are stats  mining with 2 gpus  I pull 505 watts on kill- a-  watt meter

I am doing 2 1080tis.

no cpu mining with the ryzen 1800x

power up  the cpu mine monero 7

watts jump to 555

505 = 12.12 kwatts a day

555 = 13.32 kwatts a day  

at 10 cent I am   $1.21 a day  gpus only
at 10 cent I am   $1.33 a day   gpu + cpu

at 20 cent I am   $2.42 a day gpus only
at 20 cent I am   $2.66 a day gpus only

I earn  5 dollars with the gpu and 60 cents with the cpu.

worst case  is 60 cents - 24 cents = 36 cents  extra with cpu

best case is 60 cents - 12 cents = 48 cents extra with cpu

reality for me is maybe I gain 40 cents a day with that cpu.  that is paid off fully.

so for the 1800x  it is worth having.

my guess is the 2700x may be good.

thread ripper 2 is a long way off have to wait and see if it is worth it.


below was not accurate  I set a meter up and results above are good.

the 1800k pulls about 100 watts maxed  that is 2400 watts in a day  at 13 cents that is 13 x 2.4 =  31 cents a day. and I earn 60 so I net about 30 cents.

Why not take the 30 cent profit.

https://www.amd.com/en/products/cpu/amd-ryzen-7-1800x

the 2 gpus make  about 6 a day burning  350 watts.

so 6.60 earn  and  350 + 100 = 450 watts  that is 11 kwatts at 13 cents = 1.43 in power cost.

so this rig nets 6.60 - 1.43 = 5.17 usd a day.

phil - help me here with some 100 level economics.  Btc price right now is less than 7k.  If one believes that btc will be worth $xx,xxx.xx a coin in the future, isnt there value in mining at a "loss" now, to acquire btc?  This is something i often find myself thinking about.  It's a like a tug of war in my mind.

Complex question.

Selling gear say an older s9 for 500 in btc.

Or mining at a loss.

I would say sell the gear.

How long does it take to earn that?

About 110 days to earn .071 btc.

If you sell the s9 for 500 you have the btc today.

I constantly hedge cash coin gear.

And try to get more solar done.

Has anyone looked into the specs here, looks like a nice upgrade for some of you.

If you're looking to build a gaming PC that could be used for mining while you aren't using it, then this could be for you. However, if you are solely at it just to profit from mining, then this CPU would probably be a bad idea. GPU-mining is coming to an end, much more CPU mining. Invest wisely, do the math, don't just be blinded by the specs.

Well since monero has promised to fork against asics.  This cpu could be okay

Along with the m.2 fpga accelerator and one Vega gpu


Gotta love Monero's dedication to CPU mining!

Yeah I have an 1800x it makes 60 cents a day and burns 30 cents to do it.

So 30 cents a day while it mines with 2 1080x

What the heck is going on with the market? This sudden drop of all coins. Did something just happened and I did not read about it? Weird...

I'm still chasing ravens with my 1080ti, I'm happy with the rewards so far. And sometimes I switch over to Luxcoin.

I am holding 5200 ravens

I am Mining zec to btc

I am Mining bis and holding.

I purchased some btc today at 6700 usd a coin.

I am holding most everything in cash.

22k cash
10k coin

Gear may be worth 15k it is all paid off.

If the room rate is 95F, I think you will have problems. I have one that rarely runs longer than 24 hours at 20C and the receiver temperature is constantly 28-30C for some reason.You may or may not get the results you are looking for right now. I have two working in my basement, here's the pace at which they work, with the shift -1/32/75 and 31/77 with suction pulling the cold air and most of the heat, I live about an hour of ST. Pittsburgh, Pennsylvania.

when set to lower voltage numbers gear runs okay at 95f

If your gear is not working at 20c  

you have:
 bad unit:
 bad psu
 or you set voltage too high 0 or +1

none of us had issues at 20c

Maybe a bug got stuck in the gear.

Problems abound due to the huge fall runup.

Bitmain saw really big profits last year.


So much so they got ideas on what to do with excess profits.

I find it very interesting that  innosilicon now has

A better zec miner more hash less power.
A better decred miner more hash less power.
A better sia miner more hash less power.
A better sha miner more hash less power.

As compared to bitmain.

Yeah bitmain is cheaper but the specs are better for innosilicon.

This kind of proves how ridiculous it is that people are howling for hardforks every time a new asic comes out.  Obviously they are butthurt that their GPUs will no longer be as profitable.  But when multiple companies are making ASIC miners and competing with each other, how exactly does that cause centralization?  No different than only 2 GPU companies competing.   The notion of decentralization based on expensive and inefficient but widely available (though availability is a subjective term) GPUs is kind of idiotic.  It would almost be like rules requiring all prospectors to use pans from the 1800s for gold mining because its more fair than large companies with industrial equipment.

I ask for no nasty attacks you did a nasty attack I deleted this.

This thread is not to say asics rule gpus suck and fpga's are tripping ..

All three have a place in the game. I don't want to discuss why the game fails without all three and even cpus are needed for the game to work.

If you choose to be all asic good it is your choice. If you choose to be inclusive also good that is your choice.
If you choose to insult gpu miners in this thread or insult asic miners or insult fpga miners or insult cpu miners with terms like butthurt or idiotic  I delete it.

back to the thread.  solar has some value in smaller ops off grid.

buysolar has spent months looking for a good inverter converter power source for a 1000 to 1600 watt setup.

My push is in this direction here is why.

Lets take sha-256 asics 

 I own t1
avalon 841
s9
s9i on the way.  all of them run about 92 to 110 watts per th

the new go B2 lists at 81 watts per th.

even if bitmain and avalon do 7nm  they will not go much better then 75 watts per 1 th.

so do some math if the solar setup I get built comes to 4 cent a kwatt over ten years

vs 10 cents a watt buying from a hosting service.

it is viable  to run a 110 watt per th miner
vs a 75 watt per th miner.

So the game goes back to low power cost = winner winner chicken dinner.





Sorry if I offended you Phil.  I wasn't attacking anyone or any style of mining.  In fact, I don't own ASICs or FPGAs, only GPUs and CPUs.  Let me rephrase my point;  I think its shortsighted and misinformed to want a coin to hardfork simply because an Nvidia or AMD GPU is no longer the most cost effective way to mine.
lol why ? you think it’s shortsighted, but give no explanation for your reasoning, leme guess becuase nothing you could come up with makes any sense.  There is zero benifit to letting asics canabalize a tokens network
It defeats the whole point of decentralization

neither of the above  are nasty posts thank you both.

I don't want us to spend time defending or attacking  asic/fpga/gpu/cpu mining or pow vs pos vs (pow+pos hybrid)

The reality is we have that world to live in or mine in we don't need to argue  why one part is good and the other part is evil.

The game today as we mine is cheap power is king  and lots of cheap gear can be found  how do we cope as miners.
19874  Bitcoin / Mining speculation / Re: How about a solar power source for pop one price mining on: June 10, 2018, 04:02:02 AM
You may be right about shell LLC's designed to block all warranty claims, but it is possible to shield electronics from wind, wet, and snow.

I'm not saying it is street legal, but I have used your typical eBay inverters (sellers like: ChargerAngel) to backfeed power into my residence.  The inverters are housed in marine battery boxes, with the top vents sealed with silicone.  It's cheap, and the inverters have made it through snow, rain, Nor' Easters, and hurricane Sandy.  Solar is pretty damn set it up right and forget it.  Completely different than setting up miners.

If you can find a good spot to lean solar panels up against your dwelling, you can do this.  You don't need to roof mount, you don't need fancy frames.  Use the space underneath the panels to house inverters and whatever other electronics you are working with.  Keep everything off the ground by a foot or two or three.

I haven't put a miner outside, but so long as it is elevated off the ground, and there is a decent plastic housing that is waterproof, I see no reason why this can't be done.

Also:  spray silicone can help so long as you let it dry completely.  As in apply it, go away for a week or more before applying power to what you sprayed.  Yes, I have done this.  All my Vega cards were stripped down, sprayed with silicone, Raijen Morpheus heat fins & 120mm fans applied afterwards.  Very quiet, cooler than the reference blower, and running just fine.

Try the silicone spraying on something very cheap.  Let it dry thoroughly.  Test it.

the panels we use are these

http://sepbatteries.com/ecosolargy-230w-poly-crystalline-solar-module?gclid=CjwKCAjw9e3YBRBcEiwAzjCJuolmm5yZWCBbii562Sy355bQTVhVhQZCgbk4m4QsQCvCwwwL5c7LMxoCsYYQAvD_BwE

they are 39 by 64  inches

seven are about   23 feet  wide by 5 foot 5

should do about   1610 watts which may do an s9i  will certainly do 2 L3+ on a bit of a down clock

The game at the moment is cheap power.  If you build the power source/panels for 1k it is viable plan with a path to profit.

Most people can't do this as they can not source parts cheap enough.

the cost for the panels on that website would be 7 x 100 = 700 so you would need to spend under 300 for inverter.

as for keeping the gear dry the big issue would be down time on the s9.  as it would be turned off most of the 24 hours. and run for 6 hours or so each day.

in the winter cool air may prevent it from starting when sun comes up.
19875  Bitcoin / Mining speculation / Re: How about a solar power source for pop one price mining on: June 10, 2018, 03:49:37 AM
[...] Basically it has been tried already in the days when Bitcoin could still be mined by the GPU cards. Some guy did that in Germany or in Finland. It was linked on this forum, but either I can't find it or it is gone. He couldn't keep his setup working even a single full year.

The main technical point is that protection from the elements in a non-trivial undertaking. It is not only about keeping it cool, it is also about keeping it warm and dry when not operating or operating with constrained power.

The moisture condensation and icing will void any warranty for the electronics, unless you buy marine-rated equipment.

Additionally, the warranty on panels in the USA will probably be unenforceable. I've been told that those companies reselling and installing the solar equipment are intentionally created to go bankrupt, they may as well offer 100 years of warranty. That is apparently some political stuff more difficult to explain, which I don't fully understand. I didn't see the actual panels discussed in this thread, but I've seen some other sold and installed in the USA and they weren't designed to last.

I'm sorry for raining on your parade.

Yes, but let's dust off the MagikSmoke 8 ball and look at the next few months:
-snip-


Great analysis and summary of GPU outlook overall. This should be stickied for all those still asking "will GPU mining still be profitable?"

I'd like to get your opinion though, does this mean to you that the best time to sell GPUs would be today? I'm asking because i'm curious if we can still ride out our GPUs for 1 or 2 more months before the shit hits the fan. I'm pretty happy with ROI and all the coins i already have for long-term holding.

I sold off my 1070's.  Sold off my RX 480s.  I reduced my 1080 Ti's but keeping some, and keeping my Vega's for now.  I do think 1080 Ti's are not going to go to $0 any time soon but I do keep a watch on eBay.  If you've gotten your purchase price back out of them, not as big an issue.

Never had an ASIC miner until this year, and boy has that been a turn off.  I ordered one of the Senseless modded FPGAs.  Happy to share with the group how that goes once I get it.

In the meantime, I've got to dig out a small manual I put together on how to setup a *small* solar system.  I'll post it when I find it.  It's not that difficult to do on a small scale.  There are some good YouTube videos on how to make the connections, etc.  The tools needed are cheap:  Harbor Freight crimping tool, bulk connectors from ebay (China Post), inverters depending on what you want to do, or battery controllers.  Main advice is this: if you buy panels, get the largest wattage that are cheap.  Don't waste your money on 100w panels.  Start with a 200+w or 300w panel.  There are some crazy sales on those every now and then.  CargoLargo was dumping a bunch a few years ago, and that kind of opportunity is not uncommon.  And remember that DC only travels a short distance before significant losses; AC travels much further -- so place your inverters on or close to the panels, do the long runs with AC.

For 2018, here is what I like:  smaller honest pools like what Marvell2 has done.  I'd like to see others in the group follow.  Solar power where you can fit it in like Phil has been mentioning.  And I do think FPGAs are going to be the next wave, but that's just my educated guess.  YMMV.  Oh, and screw Bitmain.  I kept an open mind on them until I experienced up close and personal how they work.  How can a billion $ + company have such completely crappy service?  Wonders never cease.

Edit:  Please no more of these "kudos" to Vorrick or for that matter Zooko.  Tools, nothing more than tools...


we Try to get 200-230 watt panels  at 20 cents a watt or less. We can do this  at auctions of new old stock.

we sometimes get this under 50 bucks. 7 at 50 give 1600 watts for 350 usd  it is about 3 by 5  well 39 inch by 64 inch

you need 7 of them  to run an s9 for about 5 hours a day

http://sepbatteries.com/trina-310-watt-tsm-310pd14?gclid=CjwKCAjw9e3YBRBcEiwAzjCJutlBzUkSK_DiijhNqGCna7eU7Zg0Va-bNCJ6om25iqvOLIgyzJiqjhoCDhMQAvD_BwE

this one cost more hard to get under 100  it is about 3 by 6    5 of these  would be a 15 by 6 foot row.  and provide about 1500 watts 5 hours a day . cost of  500

the key is find deals have space for a row.

you need an inverter/converter plus some wires.

if you have a spot and get this setup for 1000 bucks you could see 7.5 kwatts a day for more then 10 years  that is 7.5 x 365 x 10 = 27000 kwatts of prepaid power so to speak.

So is it worth it ?  well it makes mining gear of any kind earn money since the power cost is up front.

if you get 27,000 kwatts for 1000 you paid under 4 cents a kwatt.

as this project goes on  our goal will be well priced panels  and well priced converter/inverter as a diy kit.

I have multiple photos of   a doghouse to house the miners

https://bitcointalk.org/index.php?topic=4415357.msg39741539#msg39741539

that doghouse setup is well under 100 bucks.  So since the row of solar is say 15 by 6 or maybe 18 by 5  the doghouse size is not much of an issue.


the panels I show above are too costly at those links.

the 230 watt is listed for 101 usd it needs to be 50 usd or less
the 310 watt is listed for 145 usd it needs to be 100 usd or less

you need a 1600 watt inverter/converter with good warranty.

buysolar has 7 230 watts panels wired I have the doghouse setup we are waiting on inverters. to fully test.


As a small system 1400 to 1800 watts would be max.  to be practical.
no grid tie
no battery

and
4 hours north               6.0 kwatts
5 hours less north         7.5 kwatts
6 hours more south       9.0 kwatts.

We are sure about the enclosure
we are sure about the panels
eth wires etc all pretty sure.
inverter/converter is our unknown it needs to be good and not costly and water resistant /proof

Phil, i met Sky at the training at Canaan in Beijing last April. I believe solar is a very powerful and possible idea for south american and central american countries. Excited to see the develop of this, and if you need to test this here just let me know Smiley Sky has my contact info



I do have a prototype  that can hold 2 L3+ or 1 S9i

It is outdoors a doghouse available at Amazon.com

I am going to take a photo or two of it now.

about 28 inches long

about 25 inches high note air intake

note air leaving
https://i.imgur.com/th1HHmF.jpg

pair of L3+
https://i.imgur.com/vERn9pS.jpg

could use 1 s9i I am waiting to get some to check how well it cools.

2 L3+  doing voltage mod pull 1360 watts and run cool

https://i.imgur.com/CB8Phmg.png

Note to mods this is not about  L3+  As my goal is to build this with s9i

s9i is cheap  my tests show power and heat can be managed for L3+
the s9i come soon  will show tests for it when it comes.

Sky has inverter/converter power source on order.

If we can  build a solar power source with this in the 1500 watt range doing 5 hours per day in NJ  where 13.7 to 16.7 cent power is common  the source gives 7.5 kwatts a day   that is 1.03  to 1.23  usd a day in power or 375 to  457 usd in power in a year.

The power source should have a long life  no batteries involved
Easy to setup  no grid connection.

the panels rate 20 years
the inverter/converter is 5 or 7 years.

So if we can sell it cheap enough it could work out.

Of course practicalities come in
maybe the ratings are too high .

maybe it does not last the timespan it should 

we won't know till we rest a bit.
