Description

With the Antminer DR7, Bitmain presented a miner for ScPrime in June 2024. It computes the Blake256R14 algorithm and reaches 127 TH/s. It is cooled by four fans, and its power supply is built into the housing. It is no longer available.

‍

Performance of the Antminer DR7

At 2,730 watts that gives 21.5 joules per terahash. Both values apply at the wall socket at 25 degrees ambient temperature.

‍

Design, connection and cooling of the Antminer DR7

The DR7 measures 430 x 195.5 x 290 mm and weighs 16.1 kilograms, power supply included. For shipping, that becomes a parcel of 570 x 316 x 430 mm and 17.7 kilograms. Four fans cool it, and in operation it reaches 75 decibels.

‍

Two power inputs at 10 amps each supply the DR7 from 220 to 240 volts at 47 to 53 hertz; for the network it has an RJ45 socket. Permitted are 0 to 40 degrees ambient temperature and up to 2,000 metres of altitude, with the temperature limit dropping by one degree per 300 metres above 900 metres. Humidity may lie between 10 and 90 percent as long as no condensation forms; storage is possible from minus 20 to plus 70 degrees.

‍

The DR7 shares its dimensions and weight with the Antminer HS3, which Bitmain brought out for Handshake a year and a half earlier.

‍

Verdict: ScPrime mining with the Antminer DR7

The DR7 is the only machine we have that can mine ScPrime. So far, the DR7 units we have shipped are doing their job properly.

Warranty provided by our German Company

When you buy mining hardware via Cryptohall24, you get a guarantee of 12 months In contrast to manufacturer warranties, our warranty only begins when the hardware is sold to our customers and not as soon as it leaves the factory. Since there can often be several months between production and sale in the mining market, our customers often have a longer effective protection than with the pure manufacturer's warranty.
‍
Optionally, the hardware can be added to insured for up to 36 months become.

FAQ
Do you have any questions?

How does buying a miner work?

The process is clear and done in a few steps: you enquire about the device you want, you receive a written quote with the final price from us, and as soon as you accept it, we issue the invoice. After full payment is received, we trigger the order and the hardware is on its way to you.

That way you know where you stand at every point - from quote to delivery, a continuously supported process with a personal contact.

How can I pay?

You can pay conveniently by bank transfer in euros, in crypto (Bitcoin or USDC) or in cash against a receipt.

As throughout our business, payment is in advance: we trigger the order as soon as payment has been received in full. That keeps the process clean and predictable for both sides.

Are there discounts for larger quantities?

Yes, discounts are possible for larger quantities. How large they are depends on several factors - the device, the quantity, the delivery location and the respective procurement conditions.

That's why we state the right price best directly in an individual quote. Just tell us the model and the quantity you want and we'll work it out for you.

What is included in the delivery?

On modern ASIC miners the power supply is built firmly into the machine and is therefore always included - it does not have to be bought separately. An external power supply only existed with very old first-generation models.

So you receive a ready-to-run device. Whatever else specifically belongs to the respective product is stated in the product description; in case of doubt we clarify it in the quote.

Is the miner in stock and how quickly is it delivered?

You can see availability directly on the product; in case of doubt we confirm it in the quote. The majority of our hardware is located in our main warehouse in Hong Kong and is shipped from there directly to your destination.

Individual devices are in stock in Germany (Hamm) - those reach you particularly quickly. We state the concrete delivery date bindingly in the quote, as soon as device and destination are clear.

How is it delivered - internationally and with customs clearance too?

We deliver worldwide. We handle the shipping and the complete import processing including customs clearance for you - you don't have to deal with it yourself. We state the shipping costs transparently in the quote.

That way the miner arrives ready to use at your place or the desired site. On request we deliver directly to our hosting, then the device goes into operation without a detour.

What requirements do I need for operation?

To operate at home or in your own business you mainly need three things: a suitable power connection (ASIC miners draw several kilowatts continuously, large devices often three-phase power), enough space with ventilation, and a stable internet connection via LAN.

On top of that come noise and waste heat: air-cooled devices are very loud and heat the room noticeably. Anyone who doesn't meet these requirements usually has the miner hosted - then we take care of power, cooling and operation.

How do I set up the miner and can I get help?

Commissioning is straightforward: connect the device, plug it into the network and configure it to your mining pool and wallet. After that the miner runs around the clock.

We don't leave you alone with it - we support you with setting up pool and wallet and the first steps, even without prior experience. Your personal contact is available for questions.

What warranty do I have on the device?

As a German company we offer you 12 months' warranty on your hardware as standard.

Alternatively, you can exclude the warranty in the purchase contract and handle it via the manufacturer's warranty - then the device becomes cheaper. We offer both routes; which one makes sense for you we clarify in the quote.

Can I have this miner hosted directly instead of running it myself?

Yes. You can buy the device from us and have it hosted in the same step - then it runs at a site with low-cost electricity, without noise and heat at your home.

For many this is the most economical way. You can read how hosting works on our hosting page.

As a business customer, can I cancel or return?

We sell our devices to businesses (B2B). A statutory consumer right of withdrawal therefore does not apply in B2B business; in addition, we procure and import the hardware specifically for your order.

So you buy in a targeted and binding way. That's exactly why we calmly clarify the right device for your project before the quote - so you make the right choice from the start. If you have questions before buying, we are always reachable.
