SGMiner-GM is a revitalization of the sgminer project (source), brought to you by Genesis Mining and being developed and maintained by Philipp Otterbein, OhGodAGirl and Wolf. The latest version sgminer-gm-5.5.5 comes with support for ETH, XMR and Zcash and NiceHash has also just released a fork with support for their services for using the miner for selling your hashrate on their service for Ethereum and Monero. The recently added support for Zcash mining using sgminer-gm relies on the Zawawa’s Gateless Gate implementation, so it is not very competitive as compared to other faster solutions at the moment.

Similar to the Zcash implementation not being the fastest out there, there are also other algorithms supported by the SGMiner-GM project that may not be the best performing for the moment hashrate-wise. You can however try mining Monero (XMR) with this release of the sgminer-gm as opposed to other alternative miners as it seems to be performing very competitively hashrate wise as well as in terms of power usage. Below you can find a Windows binary of the latest xgminer-gm 5.5.5 release ready for you to try out if you want to check it out. It is the official sgminer-gm and not the fork with NiceHash support, so if you want to use NiceHash’s services use the link above to download their fork.

Another interesting piece of information about the popular ASIC manufacturer Bitmain as apparently the company is planning to launch their first Antminer L3 Scrypt Miner. Some of you might remember that back in 2014 Bitmain was planning to launch Antminer L1 Sctypt ASIC miner, but that one never came into existence. Apparently back then the company reached a stage that allowed even without launching a product to continue working and get an even more efficient solution and here comes the L3. There is some information available about the device already, even though it is not yet officially listed on the English website of Bitmain (you can find a product page on the Chinese one).

You can find some photos and even some early performance results online from peopel that managed to get some early units apparently, including a tweet from charlie Lee who created Litecoin (LTC) about getting one of these devices. More general availability is expected sometimes in February probably because of the incoming Chinese New Year, so we are going to have to wait some more time. What is the most interesting thing about the Bitmain AntMiner L3 Scrypt ASIC miner is the efficiency that the device not only apparently promises, but also delivers – 250 MHS hashrate with just 400 Watt power usage. This makes is significantly more power efficient compared to its only competitor with a recent generation of Scrypt ASIC hardware available – Innosilicon A4 Dominator (280 MHS at 1000W). The price listed on the product page is 1.825 BTC or a little over $1600 USD at the current exchange rate. Do note that the Antminer L3 ASIC does come without a power supply, but with the power usage the device has it does not require expensive and harder to find power supply, a decent 500W PSU should do just fine.

Bitmain Antminer L3 Specifications:
– Scrypt mining hashrate: 250 MHS
– Power consumption: 400W ± 10% (at the wall, with Bitmain’s APW3-1600 PSU, 93% efficiency, 25°C ambient temperature))
– Power efficiency: 1.6J/MH ± 10% (at the wall, AC / DC efficiency of 93%, 25°C ambient temperature)
– Rated voltage: 11.6 ~ 13.0V
– Chip Type: BM1485
– Chip quantity per unit: 144 chips
– Number of boards in the whole machine: 4 pcs
– External dimensions: 230 mm (L) * 135 mm (W) * 158 mm (H)
– Machine weight (without packaging): 2.5kg
– Operating temperature: 0°C to 40°C
– Operating Humidity: 5% RH-95% RH, non-condensing
– Network connection: Ethernet
– Noise level: 60dB

Bitmain has announced a new AntMiner T9 ASIC miner that should go on sale today for $1104 USD offering 11.5 THS hashrate. The new miner is based on the previous AntMiner S9, though it comes with a bit less chips that are apparently clocked at a higher operating frequency. The new T9 is a bit cheaper, but not as efficient as the S9 as based on the official specs it consumes about 1450W for the 11.5 THS while the Batch 22 of the S9 came with 11 THS at 1078W and Batch 23 was with 14 THS for 1372W. The new T9 miner comes with just 171 BM1387 chips while the S9 was based on 189 BM1387 chips. The two fans cooling the new device are the same as on S9, so you can expect similar level of noise from the device. So in short the new AntMiner T9 does not in fact seem so attractive to miners, but with the lack of new S9 miners you might not have much of a choice…

BitMain AntMiner T9 Specifications:
– Hash Rate: 11.5TH/s. A variation of +/- 5% is expected

– Power Efficiency: 0.126J/GH + 7% (at the wall, with Bitmain’s APW3 PSU, 93% efficiency, 25°C ambient temperature)
– Rated Voltage: 11.60 ~ 13.00V
– Chip Type: BM1387
– Chip quantity per unit: 171 chips
– Dimensions: 350mm (l) x 135mm (w) x 158mm (h)
– Cooling: Two 12038 fans. Front fan: 6000RPM, rear fan: 4300RPM
– Operating temperature: 0°C to 40°C
– Network connection: Ethernet
