Canaan Technology Launches New Avalon A13 Series Bitcoin Miners

Canaan Technology Launches New Avalon A13 Series Bitcoin Miners According to the latest news, Canaan Technology announced the launch of the new Bitcoin miner Avalon Made A13 series, including Avalon A1346 and Avalon A1366. Canaan Technology said that the new generation of miners uses advanced ASIC technology, and the A13 series will include two different models. Compared with the 90 to 100TH/s hash rate offered by the A12 series, the A13 series has both hash rate, and energy efficiency has been enhanced. Canaan's CEO said the all-new A13 is a milestone in the company's over-computational energy consumption analysis. The model A1346 has a hash rate of 110 TH/s and an energy efficiency of 30J/TH. Model A1366 has a hash rate of 130TH/s and an energy efficiency of 25J/TH. Comparing the energy efficiency ratio of Bitmain's flagship S19 XP of 21.5 J/TH with that of Bitmain's M50S of 0.026j/Gh, the new series of A1346 is "very competitive" in terms of efficiency at

Antminer L3++ Litecoin Miner Review

Antminer L3++ Litecoin Miner Review

L3++Antminer
At present, the Antminer L3 series includes three versions: Antminer L3 (Hash rate 250Mh/power consumption 400W), Antminer L3+ (hash rate 500Mh/power consumption 800W), Antminer L3++ (hash rate 580Mh/power consumption 942W), all use BM1485 chip.

L3 series LTC miners are also known as Scrypt miners. Besides Litecoin mining, it also works with any Scrypt-based cryptocurrency.
This time, we will review the Antminer L3++.

Unpacking photos

Antminer L3++ is packed in an industrial carton with complete logistics and storage labels and brand logos.

Install and test

The installation settings of Antminer L3++ are similar to Antminer L3+ models. It is recommended to refer to the Support - Asic Miner Manual page of ZEUS MINING's official website. After the setup is complete, the miner starts running after tens of seconds. Live status is displayed on the Miner Status page.

Performance testing

The test uses the Antminer APW3-12-1600-B2 power supply, and the conversion rate is as high as 93.5%. In this test, the indoor noise is about 39dB, and the indoor temperature is about 26°C during the day and 20°C at night.

The default frequency is 450, long-term operation, the average hash rate is about 593M, the curve is stable, and there is no apparent fluctuation.

The test power is 1040W.
power test
Overclocking concept: Each miner is slightly different according to its quality. Under the premise of stable operation, it can be increased by two to three gears each time. In our tests, the default frequency was 450, raising the third gear to 469.
overclocking options
The average hash rate after a long run is around 610M.
average hash rate
The test power is 1080W.
power consumption test
During regular operation, the fan speed is about 4300 rpm during the day, and the measured noise is about 83dB at a distance of about 20cm from the miner.
noise measure
The default setting of the fan speed is automatically adjusted according to the ambient temperature. During regular operation at low temperatures at night, the fan speed drops to about 3900 rpm, and the measured noise is about 80dB at about 20cm.

In terms of temperature, when the miner runs normally and stably, the chip temperature on the "Miner Status" page is 50-58°C. However, the measured temperature of the air inlet is 30.1°C.

The measured temperature of the air outlet is 34.6 ℃.

Generalize

·LTC Antminer L3++ is an optimized and upgraded version of L3+, and the hash rate of a single miner is increased by about 90M.
·Long-term stable operation, the measured average hash rate is about 593M, and the power is 1040w.
·There is a particular overclocking space (depending on the actual situation of each miner).
·Applicable to all cryptocurrencies using the Scrypt algorithm.
·A bit noisy, but now common for large hash rate miners.
·Good heat dissipation, the slight temperature difference between front and rear, conducive to long-term stable operation.
·The compact and robust design makes it easy to handle and is mainly used in mining farms.
