At current DCR price and current difficulty, CryptoCompare's mining calculator (https://www.cryptocompare.com/mining/calculator/dcr?HashingPower=7.8&HashingUnit=TH%2Fs&PowerConsumption=1410&CostPerkWh=0.16&MiningPoolFee=1) estimates $530/month in profit at $0.16/kWh. Obviously, this will change as the price/difficult changes.

That power efficiency is so so bad, if you compare it to the WhatsMiner D1 44Th/s.

This antminer takes about three times the power per hash.

Great point, but keep in mind that the Pangolin Whatsminer D1 (https://pangolinminer.com/product/whatsminer-dcr/) is out of stock and costs roughly 5 times more (total).

It's manufactured by MicroBT a.k.a. Bitwei.    www.microbt.com


Pangolin is a distributor.
They seem to have december batch for sale https://pangolinminer.com/product/whatsminer-dcr-with-psu-shipout-on-dec-5/

but I agree it's a long time before december hits

530 dollars a month profit right now seems great. I don't know how it last because usually the ASICS start going down in profit once many people start using them, just as GPU-mining, only here the profit decrease at a much faster rate.

Yet this ASIC seems doing really well even at a 0.16 kw/h power consumption, so probably the people with cheaper electricity I think will buy 2 of them. It seems so enticing right now.

Plugging in the numbers, it's $12/day revenue, $9 profit at 9 cents power.

Assume they ship 3k units, which increase difficulty by 25% over a month, revenue down to $9/day, profit $6/day. Seems like a 100 day payback investment, but whatsminer DCR shipping in 60 days.

Nah this will get wrecked.

Maybe after December, only the whatsminer miner can make profit due to the high efficiency.

0.27 the efficiency of the Whatsminer DCR. You plug in the DR3 in October and DCRs start pumping in November. ROI by December and make whatever small change is left by the Whatsminers. Doesn't seem really worth the trouble to me.

But it won't be worth mining in December.  You will never see payback on their $4000 USD miner.

I jumped and ordered 2 of the Antminer's early this morning hoping to see payback.  Still very risky.

I was early on the Z9 mini's which had a similar quick 2 month payback.  3 months later mining about 30% from where it began and still not paid back.  Will be lucky if that happens by year end.

An now we have the Trump tariff to pay on these miners.

You guys are also forgetting that Obelisk is also shipping out their Batch 1.  They are tweaking the firmware and batch 2-5 will follow suit

Then why you ordered the DR3's?

At least Bitmain is doing the Maximum order quantities or these. I wonder how many we can source for buyers for Sept. Our listing should be up in a few hours but a soft quote is looking like over $1k to import to the US using web service payment. Most of our international buyers decide to take on customs responsibility themselves and we're seeing more US buyers request quotes to do so as well.

Forgot to ask how this rates with Innosilicons model?

DR3 is 2.4 times more efficient.

this profit right now seems great but I could not find any difficulty chart, In my country the energy is worth $0.065 and how I calculate the difficulty change and how much time will need payback?

There's no way to know that for sure but the difficulty is expected to increase significantly based on all the different manufacturers that are releasing miners for this algorithm.

If antminer holds the max of two for first batch these look to ROI before the D1 is shipped out.

Now Decred have got  80Ph...
This miner have 7.8 Th of hashpower...
Is equal about 10500 Miner... if Bitmain sell 5000 Pcs the reward ( now is about 14$) decrease until 7$.
The cost of electricity is important... ( 1400 watt equal to about 34Kwh/day....)
I think that if we are lucky ( low electricity cost ) ROI is about 220/250 days...... if we are unlucky ( hight electricity cost) ROI is about 1 year or more...
During this period more powerful asic miner arrive........

Note that if you use an APW3++ PSU @ 93% efficiency the power usage at the wall will be 1516W.

--Edit:
I realized that's wrong: Advertised 1410W consumption is already measured at the wall.

Here bitmain goes again trying to churn out a non efficient miner quickly to kill competiton and wreck their market like the D3 and oblisk

what a foul miner this is.

IF you want 44ths DCR miners get at me far more efficient than this bitmain old crap they've been mining with for months.

I'm a gambler.

Always good to hear a salesman put down the competition. ::)

:D  ;D

its easy when they make such shitty miners

Was on crack earlier? I see only profits of $10/day with $0.12 power cost with this unit now. 

Batch 1 is SOLD OUT now!

looks like people are buying these up..

One algo, one coin, Not the most efficient, difficulty will skyrocket , not worth it unless you have free or very cheap power.

nailed it lol

Bitmain likes to do dirty tricks with SOLD OUT to cause FOMO to save their company from going bankrupt. Nice try bitmain, that worked last year but 2018 is way different.

This shit ain't sold out. Especially with 25 percent added tariff's and a far superior DCR miner comming out from. Whatminer, plus obelisk DCR going online. I would not touch bitmain DCR with a 10 feet pole.

If you want DCR that badly just buy the damn coin. You'll get more units more so than what a miner can ever generate . Crypto is risky enough and mining is even riskier with no reward potential with current increasing mining difficulty and oversupply of miners.

If your the guy that bought a bitmain DCR you just went full retard.

sold out of first batch.....second batch has been up since launch so they're not sold out at all.

people said the same thing on the Z9-Mini .. 1st batch buyers made out.

-Matt

The added tariffs on everything makes things even worse for us American customers; I assume this now applies to all Bitmain machines imported from China as well. I can’t really see this being profitable as of now with the way crypto is right now, but seems like a $1K gamble to me. Might make some profit, might not.

Ah, thats why DCR diff skyrocketed since about a month ago ;)

The equihash algo is huge, and it kicked out gpu miners, dcr network hashrate is not as vast, only one coin to mine whIle equihash has many, z9 mini use little power, this does not. Decred already has asics, equilhash didnt. ROI will be harder on these. The question is how many of these dr3s were contributing to the existing network hashrate for "testing".

 There's also the possibility of a second generation of dcr asics from innosillicon, the d9+ was probably just an overclocked d9. If 44th can be achieved on the whatsminer there's likely to be something  that fast around the corner.

Bitmain are probably building their new dcr asics on their new 7nm chip process, which they will start to flood the network when they have finished milking us the dr3s. Plus if whatsminer mines on their 44th miner after they sold out a batch or two it won't be pretty in a month or so.

Stick to miners that mine large major algos, eg sha and scrypt.  especially in this market. New miners will come.

So basically thanks to all these ASICs my RX GPUs will never dual mine again most likely.

Since all these algos are GPU compute, they are very easy to replicate an ASIC for.

Sure miss the days of July 2017 when I was making like $2/day extra on top of my $6/day with my RX 470 4GB mining ETH+SC.

First batch will make some money and should ROI or close but yes months of mining before release doesn't give consumers incentive to buy. I imagine the spike is do to any manufacturer developing a new blake256 miner as well.

yep. Those halcyon days of Dual mining eh. Now all blood, tears and Bitmain manipulations. What fun we have.

Exactly! I'm getting a serious dose of Bitmain's A3 Siacoin miner deja vu here. The only coin on that algo (blake2b) and it got completely destroyed in what? 2? 3 months? I'm not falling for this shit again.

lol , its hillarious they think ppl will buy these after they milked the real profitability out of these miners what 5 months ago? loool , charts don’t lie...shitmain does

actually the tarrifs are the only thing saving you fewls from making dumbass decisions, trump is saving u idiots

Innosillicion, Halong, Ibelink have been selling decred miners for the past few months.

yeah , i know that but , they didn’t sell many as to raise the hashrate that much , did you see the prices they were selling for?  Not that i think for one seccond those other companies were not doing the same

anyone get a ship notice?  such lack of enthusiasm here..  I don't think there were that many units sold for the first batch.

Someone on rebay claims to have a ship notice for "Sunday-Monday".... Yeah.

-j

Two of mine from the first batch shipped yesterday DHL.

Want to get me the firmware off of yours when they land? Willing to work with you on it...

-j

sure

Awesome, thank you. I'll PM you email (you may already have it) and we can work it out.

-j

Looks like batch shipments are gauged around their holiday. Nice that these are leaving on time.

ETA Tuesday for eastern USA. I will check with him Tuesday to see if it got there yet.

Keep us updated

Ok I have two arriving Monday as well.. what do you plan on doing to the firmware?

Matt

DHL indicates Monday delivery for me too - east coast USA.

We can still roll 20 units out batch two. Maybe watch diff till through GMT -9 Tuesday before committing. We hate wafflers here.

you guys getting slam'd on the tariffs in the USA on these yet? (I'd ask whoever ships for hidden bills later).

Also the increase in import fees to boot, I think also? (not sure, but you will be the first to know I guess, s

just asking)

thanks

brad

@Matt - hopefully unlock it if it has more potential. See my other thread on the Z9 for example: https://bitcointalk.org/index.php?topic=5036968

Jason

My order for the DR3 miners just arrived, YAY!!

Mine is arriving today. BTW, what pools do you guys have in mind?

Can it be overclocked?

was thinking this one:

https://mining.luxor.tech/

lower fees, decent overall rate and has a US endpoint..

im using beepool.org

Yes, default is 410mh/z and there’s an option to boost it to 450mh/z but I haven’t tried it though

EDIT: chain #3 is giving high HW errors above 1300 soon after startup on both of my dr3 (default settings)

The first batch is not yet fully launched, and the profit fell to 8-10 dollars, depending on the cost of electricity.
https://www.asicminervalue.com/miners/bitmain/antminer-dr3
Now purchase orders are set for October 8-15. By this time, the profit will fall several more times and the asic may not be payable.

Those who bought in September will probably earn if they sell it now :)

Luxor is good and they're only a 1% fee PPS, but they haven't implemented user accounts yet so the payouts are fixed at 0.2 intervals. I've been using Luxor and https://www2.coinmine.pl/dcr/ for the past 5 months (coinmine is 1% fee PPLNS). Both have discord channels that they are responsive to. I'm favoring coinmine right now because they have user accounts and an android phone app so you can monitor account progress remotely.

A man giving out free advice on how to make money, seems sketchier than paying $99 for an ebook lol

Are you a unix-type-person? In other words, could you tar up the filesystem and share it with me?

0j

https://asicminermarket.com/product/strongu-miner-stu-u1-dcr-hc-miner/

11TH/s at 1600w

Perhaps that's Bitmain starts its sale...

here's the fees UPS wants:

$189.18 USD

for one unit.. 

They better get those American ASIC companies up and running pronto (so we can pay like 15% more than before, but 10% less than we have to pay now)

UK import fees £120.12

What kind of temps are your dr3 chips running at and at how much wall power?

Mine temps are 88C, 85C, and 83C at 100% fan and my meter is telling me it's pulling 1570W. Miner says it's between 7.8 and 7.9 Th/s.

At least I don't have any chain errors and my HW errors are relatively low (less than 50 after 10min).

what frequencies are available by default?

Can you set a frequency other than the included ones via the browser/inspect or editing /config/cgminer.comf?

If so, I can move on, if not, I want get get the firmware and open it up.

-j

Default frequency is set to 410M. Looks like normal frequencies available to select up to 450M are available. I tried SSH into the miner with user/pass as root/root but denied. I'm not really comfortable with setting new frequencies yet as I'm still gauging default characteristics, but would be happy to get you firmware image if you know of a way.

try root/admin

that's the default unless you change the password in the web server.

Yep, those worked. Here's the interesting info of the cgminer.conf (after the pool info):

"api-listen" : true,
"api-network" : true,
"api-groups" : "A:stats:pools:devs:summary:version",
"api-allow" : "A:0/0,W:*",
"bitmain-fan-ctrl" : true,
"bitmain-fan-pwm" : "100",
"bitmain-use-vil" : true,
"bitmain-freq" : "410"

Anything specifically, I can help out with? Feel free to PM me.

Yeah, just something simple, pick any frequency that is NOT in the list on the web page, and change the '410' value to that freq. like, if 415 isn't listed, change 410 to 415. (I assume you know how to use vi? I'll try to describe the actual commands, one per line, just below this comment by pretending I'm editing it... Once that's done, run "/etc/init.d/cgminer.sh restart". All I'm looking to see is if the actual frequency changes to what you put in (like 415) or if it goes back to 410. The change will show up in the web interface with the regular miner stats.

SSH in, type these commands:
vi /config/cgminer.sh (hit enter)
/410
cw415 (Hit Escape)
:wq! (hit enter)

Then restart cgminer.sh

So that's literally typing 'c', then 'w', then '4', then '1', then '0', as if it was one word. no spaces, no enters, only, etc.

Thank you for helping as best you can!

-j

I can usually fumble my way through linux, vi, and an ssh interface.

I assume you meant cgminer.conf. The value 415 is not available in the web interface drop down. Changing the 410 to 415 in cgminer.conf results in the listed frequencies in the Miner Status page to show 415. Going to the Advanced Settings page where you would normally change the frequencies using the drop down, the drop down box is blank.

For this test, I had to reboot the miner via the web interface. How do you restart cgminer through the ssh?

Yeah,I meant cgminer.conf, doh.

This will restart it through the command line: "/etc/init.d/cgminer.sh restart"

I expect the web interface, after changing to 415, will be blank (don't worry, if you select any other frequency and apply, it'll be back to the way it was) since the web interface is reading the frequency and doesn't have a match in the html for "415".. so it just shows blank.

Ok, so if the miner status page showed 415, that suggests this one is *NOT* factory locked on frequencies.

It's just a matter of figuring out how far it can be pushed... Thank you!

-j

Just setup. Everything looks smooth under Miner Status (https://imgur.com/IjdC7vM):

https://imgur.com/a/KEq2iu9

Pulling 1487W on an APW3++ @ 18.1C (65F) ambient temp with 65% relative humidity.

Ah, so at 1487W, you don't have much room power wise to push it more with the APW3. That's getting close to the power limits on that PSU. Hmmmm....

APW3++ is 1600w so it'll do fine stock like said and is the psu bitmain "add's on" for sale with the DR3. The APW7 is same price but 1800w and same price.

Is it possible to get these miners in Serbia?

Buy them locally? Maybe, I'd just buy straight from Bitmain though.

What about asic resistence? I`ve not read enough about DCR and the new Antminer DR3, but I saw it with monero, Bitcoin Gold which in fact it became asic resistence and therefore I`m careful.

Anyone OC these?  I'm at 420 and its 8.05 gh/2

433 mhz its 8.44

Is that a bathroom? Seeing how piled up things are I'd leave at least a fire extinguisher ball in there.

Hows is the static pressure in those coolers? I wouldn't have thought these would be that loud to necessitate a sound box. 

there's alot of airflow..  its not needed but I like keeping the sound down the 8 in exhaust fan is louder than the miners..

if u can figure out how to turn sound on imgur, check it..

https://imgur.com/4HM22Sd


also good idea on the fire extinguisher balls.. I just ordered 3 for the various locations I have miners at!

POOLs:

I couldnt get luxor to work..  maybe I had the wrong url.. Coinmine works..  which is fine I have code to interface with their api so I'll just use that..

Does anyone have info on the import duty with DHL?

$189 each via UPS.. DHL should be the same if they charge it..

bathroom update, running at 83 F degrees in there.. normally 79 ..  used to hit 100 degrees when I had 28 GPUs in there.. That is with an extra 6 in exhaust fan.. so the cooler setup is the way to go! unless you plan on scaling and running a bunch.. I dont..

https://imgur.com/a/l6Qv2oT

hashrate at the pool is averaging 15.4 with the two overclocked.. one at 431 and one at 420.

im in UK
import tax
DR3   £120.12
APW3++ £35.35

What is the best pool?

best hasrate i get on mine is 8.7gh/s  at freq 450

My hashboards generate about 20 HW per minute together and lose one or two chips a few hours after reboot (status becomes "x"). This miner so far is exhibiting the stability of the D3, which wasn't great... at least compared to the S9.

27.6% listed price.

Do you guys think this is worth buying for the current batch? (considering shipping to US)

Depends on what you mean worth? US buyers won't see ROI before new equipment is released in two months on $0.10 power. If you're able to get 4mo. of good profit you may break even but that's very optimistic. Conservatively you should capture $400 back safely and push to drive market by trading to BTC to increase scarcity and value in hand. Or you're betting on bull and gearing up for a good run, or have very cheap power and can afford the risk of larger farming operation. Or you already mine blake256 and looking for cheap th/w upgrades.

Has anyone managed to lower the voltage below 1080mv? Seeing almost 1% HW rate right out of the box... ???

i clocked both of mine to the max at 450 Frequency, lots of HW errors - im at 3.6% HW error rate doing this at max frequency

From the web interface
1d6h34m24s   Current GH/S  8,526.48    AVG GH/S  8,531.99  

Both run about the same, (the other is showing 8.7 TH/s

Got 1 on monday and other on thursday (due to held up in customs).  No fees via Fedex for US customs on both (both were in same order too, dont know why 1 came monday and the other was delayed until thursday) - no power supplies ordered, but i can tell you bitmain is gaming the paperwork with random jibberish as to whats inside so fedex probably too confused on that aspect.  Different from prior antminer orders.

From the dashboard at btc.com (im in the US, using their china node so not optimized but didn't have time yet to setup anything else) as  i'm not on any pools that supported DCR stuff.  And as usual it wouldnt work at nicehash when i tried there first.

DCR earnings Yesterday
0.56099935

And its showing 17.56 TH/s avg at the pool for what it's worth and 16.5 TH/s 'real time' showing at BTc.com's pool. .  So obviously my hw errors and reported speed net down to the real number they show.

I've got too many items plugged in to tell what its pulling at the wall with the over clock sorry.  But my APC PDU shows 3.92 KW with (2) of these Antminers, and 4 x Z9 mini's and about another 200 watts for a couple of cisco ASA / switches in thatrack powered on the same pdu.  

No doubt it will be a long ROI battle at the end, but getting in as early as possible leaves some hope.

But figured that info may help some.  My opinion, its a horrible power hungry box compared to other DECRED miners coming soon, but i've learned my lesson - get the very first units, or don't bother.  Then sell it on ebay about 30-45 days in... guaranteed roi that way.   Of course just because i learned my lesson doesn't mean I will follow it, i just keep running them in the farm long past when i should sell them off usually.

My order of 2 got stuck in Fedex customs all week.  Some stupid excuse about Chinese National Holiday week.  Fedex Trade Networks was not answering the phone for most of the week.  Hold for 60 minutes then they hang up on you.

I am hoping they clear and arrive on Monday or Tuesday.

Lame, we have a few orders we just had manufacturers hold till after the holiday, so they could transit more fluidly. If we're lucky we'll see batch two ship notifications start coming tonight or tomorrow.

You ordered these into the US? With traiffs none our batch one's went into the states.

Second batch sold out. The model did find buyers.

A fewl and his money.... Ill leave that here lol

Hi , can you help me, my DR3 dont mine correctly... How resolve it ... with 2 DR3 in 24h i have win 0.1 DCR...

https://media.discordapp.net/attachments/496992210642796562/500980728981618699/unknown.png

Have you tried using other pools?

i hope everybody who bought it never make roi

This must be the worst bitmain product they came up with.

They mined this 'puppy' for months before releasing it to the public...and only after the monster innsilicon units came out and the next obelisk decred units

were to come out...this is always the case when they announce on a Friday and say they will ship yours on Friday's order, the next week! (production run is well in hand

from their previous filling up of their data halls)

this was true of the D3 the B3 and the DR3 (note the 3 where the hell are dr1 and dr2?) anyway all had quick out the door orders

it is how they roll now..make a boutique one off miner off an obscure coin in ASiC mode (1.5 months to mask the chips and 1.5 months to make the unit)

use on own data hall for months...then dump the dregs on to the silly consumers

rinse/wash/repeat

(Bitmain: We do evil well!) (tm: Bitmain)

I received my miner yesterday. I was hoping to overclock but even at the stock 410 I’m getting chip errors on the second and 3rd boards. I contacted bitmain support and their solution is to reduce to 400 and restart several times.  Even if I get the chip errors they say it’s ok as long as it’s stable and no further action is needed. What a load of BS. Brand new unit, ROI is already down the crapper and it can’t even run at the stock frequency.

Some HW errors are normal, but if it's visible affecting the hashrate keep bugging them until they replace the board.

Yes but I’m not talking about Hw errors showing in the Hw column, my boards are showing some “x” instead of O. Same thing even at 400 frequency so I’m thinking some of the chips are damaged.

About 2 or 3 chips show as "x" on 2 of my boards after and hour or so. The hashrate does not go down by much though. So I'm just letting it be.

What frequency are you mining on?

7.4 GH/s (Real Time). Chain #1 has 3 x and chain #2, 2.

Hi guys,

Does anybody have pictures of the PCB / inside of the DR3. (chips used? BM xxxx)

A3 and DR3 should be quite the same as the algo is quite the same. (check blake algo)
So maybe the DR3 is a modification of A3?

Thanks for information!

Bye, FNT

Mine is working much more stably now on 230V. While on 115V it threw hw errors at very high rate and lost chips status gradually.

I fired my DR3 back up recently.  Would like to under volt it.  I am just shy of being able to fit another miner on my 20A circuit.  Anyone under volt these?

Wondering if this script will work?

Hi.
Does anyone got firmware for DR3 from 2018? Cause this from 2019 doesnt have custom fan control
