Obelisk has started with SIA and Decred ASIC miners with a bit of controversy back in 2017, and now they are apparently planning to extend their offers with new GRIN ASIC miners for later this year as it seems this is the new hot thing for ASIC miners – the GRIN’s Cuckatoo31 algorithm. The company has announced the start of a pre-sale for their new GRN1 miner that comes in three form factors: a traditional form factor (GRN1), compact form factor (GRN1 Mini), and an immersion form factor (GRN1 Immersion). The Obelisk GRN1 miners are designed for Grin’s Cuckatoo31+ hashing algorithm and they will NOT Work on the existing Cuckaroo29+ or future Cuckatoo32+ algorithm implementations.

Obelisk will be manufacturing a maximum of 2,500 GRN1 units (60,000 chips), available in first-come, first-serve fashion. GRN1 Mini units count as 1/6th, and GRN1 Immersion units count as 2. Only 2,000 GRN1 units are available in this sale. The remaining 500 will be sold by Obelisk at market-price when production is completed in October. This sale will close on May 3, 2019. Obelisk expects to ship orders in October 2019. Below you can find the estimated specifications and prices for the upcoming ASIC miners… as you can see the prices are pretty steep, though the hashrate they deliver currently is quite profitable, but who knows what will happen by the time you get the hardware in your hands. As usual with any pre-orders and specifications announced prior to actual products in existence you should be extra careful as very often the final specs are not the same as initially announced, meaning that you could easily get lower hashrate and/or higher power consumption. Though there are cases that the final specs may be better then initially announced as well, you should still proceed with caution and also check other alternatives such as the upcoming GRIN ASIC miner from Innosilicon.

The latest two versions of GMiner 1.37 and 1.38 have increased the supported range of GPUs over what the miner was capable of running on regarding Grin, Swap and Aeternity mining as well as some additional algorithms now also supported on AMD GPUs. GMiner 1.37 added Equihash 144,5 and 192,7 solver support for AMD miners on top of the already existing Cuckaroo29, Cuckoo29, Cuckaroo29s and Equihash 150,5 as well as some minor performance improvements for beam on AMD cards. A 5GB solver for Grin29 / Swap / Aeternity was added as well that allows the mining on 6GB cards under Windows 10 and in the latest release that was further improved by adding 4GB solver for Grin29 and Swap that should work under Linux and Windows 7 on 4GB VRAM GPUs.

The GMiner miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support, some algorithms are already supported on AMD GPUs as well (Cuckaroo29, Cuckoo29, Cuckaroo29s, Beam’s Equihash 150,5 as well as the recently added Equihash 144,5 and 192,7). Do note that GMiner is a closed source miner for Nvidia and AMD GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.

It has been a while since the last release CryptoDredge 0.17.0 was made available to Nvidia GPU miners, but here comes the new CryptoDredge 0.18.0 and it brings some new and useful features on the table. The new version brings support for the Argon2d algorithm (argon2d-dyn only) as well as the much anticipated support for MTP and Cuckaroo29 on NiceHash. Prior to that the only MTP miner with NiceHash support was TT-Miner and currently MTP is among the most profitable algorithms for Nvidia GPUs on the service. The new CryptoDredge v0.18.0 also makes API more compatible with ccminer API, adds support for mining Aeternity on GPUs with 2 GB of memory (Linux only) as well as introduces support for mining Cuckaroo29 on GPUs with 4 GB of memory (Linux only) and for windows users it indicates activity to suppress auto sleep mode.

Do note that the CryptoDredge miner supports only Nvidia GPUs and is a closed source software that comes with 1% built-in developer fee for all supported algorithms, however the dev fee is 2% currently only for MTP mining (Zcoin), there are binaries available for both Windows and Linux (CUDA 9.1/9.2/10.0).
