Introduction

The period of dwelling Bitcoin mining is over, or that’s what some individuals hold repeating within the boards. Folks have been complaining that huge mining amenities inflated the mining issue at such level that it’s unimaginable for a person to revenue from mining. However is that so?

Some months in the past Bitmain launched a brand new Antminer mannequin, the R4, generally known as the “Final Bitcoin miner for dwelling”. Bitmain is well-known for his or her Antminer line. For example, the Antminer S9 is named the quickest miner in the marketplace.

Their product motto “Bringing Mining Again Dwelling” shouldn’t be with out a purpose: the Antminer R4 is by far the very best answer for dwelling Bitcoin mining. It options extraordinarily low noise ranges, nice hashrate and low energy consumption.

The miner was well-received and it gathered many nice opinions after its launch. There have been nevertheless, some technical points too. On this assessment, I’ll attempt to sum up all the things and offer you a whole image on the miner – what to anticipate from it and find out how to revenue with it.

Antminer R4 Specs

One look on the specs is sufficient to make a conclusion that the R4 has some potential.

Noise stage: 51dB (at an ambient temp. of 35C)

Energy Consumption: 845W +- 9%

Hashrate: 8.6TH/s

Working Temperature: -20 – +60C

Working Humidity: 20%-90% RH (non-condensing)

Interface Sort: 7 pairs of 6pin PCI-E connectors; 380mm size for every PCI-E cable.

Dimensions: 266mm*125mm*86mm

Weight: 2.5Kg

Package deal Weight: 9Kg

Product dimension 515mm (L) x 100mm (W) x 222mm (H)

Package deal dimension 610mm (L) x 215mm (W) x 340mm (H)

Design

Like the opposite Antminers, the R4 is huge and heavy, although not as huge because the S9. It is available in a sturdy metallic field. The steel provides each to its sturdiness and cooling. Speaking about which, the R4 is praised as one of many most silent ASIC miners in the marketplace. This is among the primary options that make it the selection #1 {hardware} for dwelling Bitcoin mining.

The R4 comes with a customized low-revolution fan, which is routinely managed by the miner. This fashion the fan is at all times spinning as sluggish because it presumably can, whereas guaranteeing optimum functioning temperature for the miner.
It runs at full velocity solely when the temperature of the warmth sink is increased than 80C. The miner additionally comes with an overheat safety.

Folks have been stunned how the miner would work quietly than a pocket book. This alone makes the Antminer R4 an awesome choice for dwelling mining.

Energy Provide

The AntMiner R4 is designed to be powered by the APW5 PSU manufactured by Bitmain. Identical to the miner itself, the PSU may be very silent. It will probably deal with each 110 V and 220 V inputs, and it outputs 1300 W and 2600 W respectively. It will probably, nevertheless be powered up by a third-party provide. It’d work barely much less effectively and clearly extra loudly. The enter voltage needs to be 12V.

Profitability

The bottom worth of the miner is 1132 USD. This doesn’t embrace the PSU, so that you would want to take a position one other 240 USD to get one. Nonetheless, you should utilize one single APW5 PSU to energy up two R4 miners in case your enter voltage is 220V. You’d additionally wish to buy a C13 energy twine that helps as much as 10 A of present.

Now let’s check out energy consumption, which might be the principle issue to think about when buying this miner. 850W is rather a lot, and your earnings may range from 1360 USD per yr (Idaho) to 622 USD per yr (New York), relying in your electrical energy value. Individuals who get electrical energy without spending a dime may count on earnings of as much as 1955 USD per yr if we don’t take note of any sudden modifications in Bitcoin worth or issue ranges.

Earlier than to proceed additional, please share this 🙂 thanks!

Hashrate and Effectivity

In accordance with opinions and exams, the miner outputs 8TH/s (Batch 3) and 8.7TH/s (Batch 4). The massive hashrate is because of the truth that it employs 126 microchips with TSMC’s 16nm FinFET expertise. That is additionally the rationale why the miner effectivity is 0.098 J/GHs.

Utilization

The R4 may be very straightforward to arrange and use. Not like most different miners, the R4 has an intuitive and clear person interface – all you must do is to attach it to the web, verify your miner IP tackle, entry to the management panel and configure the swimming pools and the pockets. That’s all you want in an effort to begin mining.

Word: The default username and password is lowercase “root”.

Identified Points

Some individuals complain that their miners lose hash energy after some days of utilization. Appears like there are a number of causes which may trigger the problem. Sadly sufficient, this drawback isn’t unusual, so I believed you will need to point out it right here:

1 Making use of modifications in the course of the warming up part may disable considered one of your boards. There’s a strategy to keep away from that, although — When you activate the miner, you must wait about 10 minutes for it to heat up and begin hashing. Solely then you possibly can safely change the Config.ini script.
2 A few of the signs of a “lifeless” or “disabled” board embrace:

No default frequency on PIC

PIC voltage altering randomly between 790 and 940

Chain 7 (J8) ASIC depend 0

Deceptive temperature studying

3 There’s an opportunity that the miner gained’t launch if the ambient temperature is beneath 20 C. Pre-heating it from the surface will normally make it work.

Now, if by some purpose considered one of your boards was disabled or “died“, there are some steps you possibly can take in an effort to try to revive it. In accordance with suggestions from a number of customers, this methodology helped to revive the boards with out the necessity to ship them to Hong Kong for guarantee service:

1) Flip off and unplug the miner from the wall

2) Unplug the working board – disconnect the white cable from the controller board

3) Launch the miner and wait till it begin to hash; give it a while

4) If the lifeless board recovers its hashrate, then flip off the miner once more

5) Plug it out off the wall and plug the opposite board again

6) Begin the miner and wait till it hashes.

Word: You’ll be able to try this a number of instances till you get the specified outcomes. You too can verify the board efficiency through Putty.
