DASH mining over the last year has undergone a huge network speed increase. Bitmain’s Antminer D3 ups that increase with a 15 GH/s X11 miner. While DASH and other coins are made to be ASIC resistant, when it becomes profitable enough to support the R&D and tapeout process, ASICs can be made for almost any algorithm. For the X11 algorithm that coins like DASH use, active development and rising value in the last year have seen several companies create small batches of X11 ASICs. The Antminer D3 brings a new manufacturer into the market. Let’s go over the specs.
Antminer D3 Specifications
- Hash rate: 15 GH/s (variation of ±5% is expected)
- Chips: 180 X11 chips
- Power consumption: 1200W (at the wall, with Bitmain’s APW3 PSU, 93% efficiency, 25°C)
- Dual exhaust fans
- 10 PCI-e power connections
- Ethernet connectivity
- Weight: 5.5 kg
- Price: $1450 USD from Bitmain
Bitmain APW3++ Power Supply Unit
- Tested using Bitmain APW3++ 1600 watt PSU
- The APW3++ can deliver a maximum power of only 1200W if it is connected to a 110V mains power supply.
- To obtain the rated power of 1600W, the APW3++ must be connected to a 220-240V mains power supply.
Unpacking the Hardware
The D3 arrived safe and sound in the usual Bitmain safe pack system. The D3 has three boards with 60 chips per board.
For this test, we used the APW3++ PSU from Bitmain as the D3 is rated for 1200 watts of power draw at 15GH/s; the APW3++ is rated up to 1600 watts and works on 110v or 220v.
Each board needs three power connections and one to the controller board for 10 total. The D3 uses the familiar S9 dual fan design in a push-pull which helps create an even airflow over the heatsinks.
Antminer D3 Simple Setup
Setup is simple. As with all Bitmain miners you’ll find the familiar control panels — as usual, setting up a custom password is first thing.
We tested the D3 on suprnova.cc pool and P2Pool nodes. The results were very similar on each pool, with the P2Pool node having a 1 percent improvement due to being a local node.
The Antminer D3 sustained 16.2 GH/s at 1186 watts from the wall at default settings. Ambient temps in the data center are 68F, which also meant the fans were running at 3200 RPM putting out 74 dB at 4 ft. As with the Antminer L3+, they can ramp up to much louder outputs in hotter conditions.
How Did It Run?
The Antminer D3 ran very stable over the course of our tests.
The DASH network has seen most of the X11 hash power being deployed to it in a short amount of time. This is good from the standpoint of securing the network, and Bitmain selling more miners to more people helps decentralize the network.
Previously, there was only a small number of miners who were able to get any of the small batches of the competitions units.
The Bitmain APW3++ PSU is another worthy entry into the market of PSUs created specifically for mining. It is not loud, and has 10 dedicated PCI-e connections. It also not very large — roughly ⅓ smaller than desktop PSUs, putting it more in line with server PSUs. The ability to run at 1600 watts on 220v gives plenty of overhead for running D3s, S9s and other miners.
Conclusion: Another Solid Bitmain Product
The Antminer D3 is another solid ASIC miner from Bitmain. Ease of use, compatibility, build quality all make it a recommended buy. Bitmain begins shipping very soon, with the first batches already sold out months ago.
DASH is the third major coin that Bitmain is producing ASIC miners for. We are looking forward to what is coming next.
