Innosilicon G32 GRIN ASIC Miners Now Up for Pre-order

17 Apr
2019

The ASIC manufacturer Innosilicon has announced the specifications for their upcoming GRIN ASIC miner and surprisingly it will not be just one device, but three different models instead… similar to the offerings of their competitor Obelisk. If you though that Obelisk GRN1 miners were pretty expensive, especially when up for a pre-order, well Innosilicon’s won’t be much cheaper. The G32 GRIN ASIC miners are a little bit lower priced, but also with lower performance and that is only the pre-order price, not the “regular” price. The estimated delivery time if you pre-order now starts in August 2019 according to Innosilicon and in our opinion this will actually be very hard to manage with three different products, unless of course Innosilicon is already ready with the chip designs. Offering a GPU type of ASIC miner could be a bit of a challenge, although it will be a self contained miner with software and everything onboard, so no need to use it in a PC apparently.

What makes Innosilicon G32 GRIN ASIC miners a bit more interesting compared to the competition is the claim that apart from Cuckatoo31+, they will have Cuckatoo32+ algorithm support (with expected hashrates announced) and that they will also be Cuckatoo29/30 backwards compatible. This makes them more flexible for the currently supported and upcoming algorithm changes, though there is no information about the expected hashrate for C29 and C30. Innosilicon also gives a guarantee for April pre-order customers for full refund if their final G32 spec after actual product testing fails to meet the above Performance Target by Sept 30th this year. There is also an extended 9 months warranty (up form the standard 6 months) and “an additional ROI boosting feature, which will be announced before product delivery”.

G32-Mini PCIe Card (Wifi capable) Preliminary Specification:
– Performance Target: 21.5GPS (+-5%) for CC31+, 4.5GPS (+-5%) for CC32+, about 10X a good GPU
– Power Consumption: 140W (+-10%) normal mode, low power mode available
– Estimated Size: Standard PCIe Graphic Card Size
– Estimated weight: 1.2KG
– Installation: Easy installation like a GPU card, in fact is easier. The card is totally self-contained with software / wifi / Ethernet port embedded. Only the standard computer PSU is needed to power the card. Each Card can work alone or be cascaded.
– Pre-order special: $799 USD (regular price: $1500)

G32-500 Preliminary Specification:
– Performance Target: 100GPS(+-5%) for CC31+, 20GPS(+-5%) for CC32+
– Power Consumption: 520W (+-10%) normal mode, quiet miner, low power mode available
– Estimated Size: 125mm(W) x 155mm(H) x 270mm(L), super small tube
– Estimated weight: 5KG
– Installation: Come with Ethernet and a 220V/110V compatible PSU. Free PSU for this pre-order.
– Pre-order special: $2888 USD (regular price: $4500)

G32-1800 Preliminary Specification:
– Performance Target: 328GPS(+-5%) for CC31+, 65.6GPS(+-5%) for CC32+
– Power Consumption: 1800W (+-10%) normal mode, quiet miner, low power mode available
– Estimated Size: 250mm(W)*155mm(H) *360mm(L)
– Estimated weight: 12KG
– Installation: Comes with Ethernet and a 220V/110V compatible PSU. Free 220V PSU.
– Pre-order special: $9388 USD (regular price: $15000)

AMD Memory Tweak Tool for Changing Memory Timings On the Fly For Windows

17 Apr
2019

The very useful AMD Memory Tweak Tool that was initially only available for Linux is now also available as a beta for Windows users as well. With the help of the free and open source software from Evilop you can read and modify memory timings “on the fly” for compatible AMD GPUs that do come with GDDR5 or HBM2 memory (HBM was also supported initially, but is temporary disabled as it apparently need some fixing). Before starting to do anything with the tool you should check the Readme and run AMD Memory Tweak with the option --current in order to see what GPUs it detects and what memory settings are currently active. It might also help to see what other users have found out as good working configurations for their hardware and have reported on Bitcointalk based on their experiments with the memory tool.

New Innosilicon A6+ LTC Master 2.2 GHS Scrypt ASIC Miner

16 Apr
2019

Litecoin (LTC) has been doing pretty well lately and no wonder that with the returning user interest in one of the oldest altcoins out there, ASIC manufacturers are also trying to attract new customers for their improved mining hardware. Here comes the new Innosilicon A6+ LTC Master ASIC miner wth PSU included promissing 2.2 GHS Scrypt hashrate at 2100W of power usage ready for shipping at a price of $3000 USD (or 0.613874 BTC or 45.034 LTC with the current prices). Innosilicon A6+ is an enhanced version of last year’s Innosilicon A6 LTC Master with improved performance and energy efficiency. The new Scrypt ASIC miner almost doubles the hashrate with just half of the power usage increase and it is interesting to note that Innosilicon still sells the old A6 miner at a price of $2000 USD without PSU for 1.23 GHS hashrate with 1500W power usage (significantly less than the initial price of $6300 USD it had when announced). Unfortunately running the numbers for the new miner through an LTC mining calculator, while profitable, the profit you can currently get over the power cost isn’t really attractive to really make you want to pull the trigger and get the miner.

Innosilicon A6+ LTC Master Specifications:
– Hashrate: 2.2 Gh/s (+/-5% performance)
– Power Consumption: 2100w ( +/-10%, normal mode, at the wall, with 93% efficiency PSU, 25°C temperature)
– Size: (L)360mm*(W)155mm*(H)247mm (dual tube)
– Net Weight: 9.31KG (without PSU)
– Internet connection: Ethernet
– Ambient Temperature: 0°C to 40°C
