Innosilicon is a professional ASIC R&D and manufacturer, covering many fields. The company's 28nm bitcoin mining chip and litecoin mining chip were among the first to circulate in China and dominate the domestic market.
Innosilicon's latest A6 LTCMaster was released in early January 2018. A6 LTCMaster is suitable for all digital currency mining using litecoin algorithm (Scrypt encryption algorithm). The official parameters are: hash rate 1.23Gh/s (+/-8%), the power consumed 1500W (+/-8% @25℃)

I. Unpacking:

The Innosilicon A6 LTCMaster is packed with styrofoam and five layers cartons box. The packing effectively provides protection from moisture and shock.

III. Testing:

The indoor noise was about 40 dBa. The room temperature was about 15 degrees during the day and about 8 degrees at night.

The average hash rate is between 1.2G-1.25 for long time operation, the curve of hash rate is stable, and there is no big fluctuation.

For overclock testing, first log in.

085838hw9l4fsdf94oqcvl.jpg

Then select "overclocking".

040857msfbvs23yizyavvv.jpg

The hash rate is about 1.29G.

040858d2k2eaaea46ymi6g.jpg

Power consumed is about 1738W.  

040859bzo18i88m86aa8oa.jpg

There are two options of frequency. They are "default" and "overclock".  The voltage is mainly adjusted to the stable operation of the power supply and the mining machine.

Automatic adjustment can also be set.
