PinIdea 17GHS X11 ASIC Miner DR-100

27, Aug 2017

PinIdea has updated their product range with a new 17GHS X11 ASIC miner named DR-100 in order to be able to cope up with the increased competition from Bitmain and Innosilicon with their recently announced new X11 miners offering significant X11 hashrate boost. PinIdea seems to be planning to start shipping their new X11 ASIC miner in September with first-come first-served principle. Currently the miner is already out of stock due to the big demand apparently (or limited number of units), even with the price of a single unit close to almost 3 BTC.

PinIdea DR-100 X11 ASIC specifications:
– HashRate: 17000 MHS (+-5%)
– Power: 820W (wall power +-5%)
– Dimensions: 28cm x 18cm(h) x 15cm(w)
– Weight: 5KG
– Interface: Lan (100m/1000m)
– Fan: 2x 14038 Double ball fan (55DB)
– Operating Temperature: 0C~40C
– Mining Software: Custom CGminer

10.8 GHS iBelink DM11G Dash X11 ASIC Miner

6, May 2017

It seems that there is a new significantly more powerful X11 ASIC miner being prepared to be unleashed, a device offering 10.8 GHS X11 mining hashrate for Dash or other crypto currencies using the same algorithm. The iBelink DM11G is apparently the successor of the iBeLink DM384M X11 ASIC Miner that we have tested last year. There is still not much information regarding the new device, although there is a group buy apparently being arranged on Bitcointalk for $6750 USD with minimum order of 1 unit as well as a Russian company Bitbaza taking pre-orders for the device at $7500 USD with a minimum order of 10 units.

The new 10.8 GHS iBelink DM11G miner does seem a lot like the first generation from last year and we cannot confirm its existence yet, though there are some photos and a video of the device in action apparently. We had some doubts when we got some information about the iBeLink DM384M last time, but then again when we have purchased one unit it turned out real and delivered what was promised. So threat this information with caution for the moment, but also be aware that this product might be hitting the market in a couple of months (3 months for shipments to start). Do note that also getting in early with a so powerful hardware can make it easy and fast to get ROI on the investment, but if the manufacturer of the device manages to put out a lot of units the profitability can also quickly diminish in a matter of a month or two. Other competitors in the X11 market might also soon release updated products to match the hashrate of this device as well, especially with the 3 month shipping time for the iBelink.

Specifications of iBelink DM11G:
– Hash Rate: 10.8GH/s ±5%
– Power Consumption: 730 W (at the wall, with 25 °C ambient temp)
– Power Efficiency: 0.07 W/MH (at the wall, with 25 °C ambient temp)
– Number of TNB0303-FL28 chips per unit: 64
– Operating Temperature: 0 °C to 40 °C
– Network Connection: Ethernet
– Power Supply: 110V to 240V, 50Hz/60Hz, PSU 850W included
– Dimensions: 490mm(L)*350mm(W)*180mm(H)
– Weight: 22 kg

Power Usage and Noise of the iBeLink DM384M X11 ASIC Miner

11, Mar 2016

Looking at the official specifications of the iBeLink DM384M X11 ASIC miner state that the device should be capable of 384 MHS X11 hashrate (plus/minus 10 percent) with a power consumption of 715W measured at the wall with 25 degrees Celsius ambient temperature. This should be the numbers for the default configuration, however we did some measurements ourselves in order to get more accurate results in order to be able to do better calculations about the cost of operating the device. We have already measured on NiceHash an average hashrate that is slightly above the official number of 384 MHS, so this is good, but what about the actual power usage and more importantly noise level. In our first impressions from the device we already mentioned that it is pretty noisy and not suitable for use in room where people will be present, but let us see what is the exact noise level as well.

ibelink-dm384m-power-usage

The power supply built into the miner is an 850 Watts server grade one that is compatible with 100-240V range (for worldwide use). The exact model is ASPOWER U2A-A20850-D and according to the official specifications is it rated as 80 Plus Silver, so a high efficiency solution. At stock settings (110 MHz PLL) the power usage we have measured on the wall with 230V EU power input was 686 Watts as you can see on the photo, the power usage in Watts might be slightly higher in US and other 110-120V countries due to slightly lower power efficiency. Increasing the operating frequency with +1 MHz steps is resulting in the power usage going up with about 5-6W on each step, so the 850W capacity of the PSU should be able to take up some nice extra overclock if the chips are capable of working well when overclocked and cooled well. We are going to be doing more extensive testing about the overclocking potential with results on the power usage and performance changes, working temperatures and cooling very soon.

ibelink-dm384m-noise-level

Now for the noise level, as already mentioned it is pretty high… just like from a rackmountable server for example. With a measurement showing about 72.6 dBA average it is perfect to be installed in a data center or a dedicated mining room, but it is not suitable for home miners as the noise level is too much for people to be in the same room for more than a few minutes… and even in the next room it might be quite noisy. The reason for the high level of noise is that the unit uses server grade fans by Delta Electronics and they are set to run at maximum RPM all the time (no temperature control). The same goes for the fan used in the power supply, a powerful Delta Electronics fan running at maximum RPM all the time, even though the PSU is highly efficient and there is not so much heat generated. The good thing about this default fans setup is that even at not that good conditions such as high ambient temperature the miner should be able to operate without any issues at optimum level. The not so good part is that small miners might have issues with the high level of noise and would probably want to do something to make it less noisy without compromising performance – this is possible with some modifications and we are already working on a solution to optimize the cooling, so more on that will be coming soon as well.
