AntMiner R4 Evaluation – Is Dwelling Bitcoin Mining Again?

January 7, 2024

Introduction

The period of residence Bitcoin mining is over, or that’s what some individuals preserve repeating within the boards. Folks have been complaining that large mining amenities inflated the mining issue at such level that it’s not possible 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, often known as the “Final Bitcoin miner for residence”. Bitmain is well-known for his or her Antminer line. For example, the Antminer S9 is named the quickest miner available on the market.

Their product motto “Bringing Mining Again Dwelling” isn’t with out a purpose: the Antminer R4 is by far one of the best answer for residence 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 nonetheless, some technical points too. On this evaluation, I’ll attempt to sum up all the things and offer you an entire image on the miner – what to anticipate from it and the right way 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 degree: 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 Kind: 7 pairs of 6pin PCI-E connectors; 380mm size for every PCI-E cable.

Dimensions: 266mm*125mm*86mm

Weight: 2.5Kg

Bundle Weight: 9Kg

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

Bundle dimension 610mm (L) x 215mm (W) x 340mm (H)

Design

Like the opposite Antminers, the R4 is large and heavy, although not as large 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 available on the market. This is likely one of the important options that make it the selection #1 {hardware} for residence Bitcoin mining.

The R4 comes with a customized low-revolution fan, which is mechanically managed by the miner. This manner the fan is all the time spinning as gradual because it probably can, whereas making certain optimum functioning temperature for the miner.
It runs at full pace solely when the temperature of the warmth sink is greater than 80C. The miner additionally comes with an overheat safety.

Folks have been shocked how the miner would work quietly than a pocket book. This alone makes the Antminer R4 an incredible choice for residence 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 could be very silent. It will possibly deal with each 110 V and 220 V inputs, and it outputs 1300 W and 2600 W respectively. It will possibly, nonetheless be powered up by a third-party provide. It would 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 embody the PSU, so that you would wish to speculate one other 240 USD to get one. Nonetheless, you should use one single APW5 PSU to energy up two R4 miners in case your enter voltage is 220V. You’d additionally need to buy a C13 energy wire that helps as much as 10 A of present.

Now let’s check out energy consumption, which might be the primary issue to contemplate when buying this miner. 850W is rather a lot, and your income may differ from 1360 USD per yr (Idaho) to 622 USD per yr (New York), relying in your electrical energy price. Individuals who get electrical energy at no cost may anticipate income of as much as 1955 USD per yr if we don’t take into consideration any sudden modifications in Bitcoin worth or issue ranges.

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

Hashrate and Effectivity

Based on 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 could be very straightforward to arrange and use. In contrast to most different miners, the R4 has an intuitive and clear consumer interface – all it’s important to do is to attach it to the web, verify your miner IP handle, entry to the management panel and configure the swimming pools and the pockets. That’s all you want to be able to begin mining.

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

Recognized Points

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

1 Making use of modifications through the warming up section may disable certainly one of your boards. There’s a strategy to keep away from that, although — When you activate the miner, it’s important to wait about 10 minutes for it to heat up and begin hashing. Solely then you’ll be able to safely change the Config.ini script.
2 A few of the signs of a “useless” or “disabled” board embody:

No default frequency on PIC

PIC voltage altering randomly between 790 and 940

Chain 7 (J8) ASIC rely 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 skin will normally make it work.

Now, if by some purpose certainly one of your boards was disabled or “died“, there are some steps you’ll be able to take to be able to try to revive it. Based on 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 useless 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.

Observe: You may try this a number of instances till you get the specified outcomes. You may also verify the board efficiency by way of Putty.
