Bitmain Antminer Z11, a New More Powerful Equihash ASIC Miner

19 Mar
2019

The new Bitmain Antminer Z11 ASIC offers a hashing power of 135 KSol/s for the Equihash algorithm used by ZCash (ZEC) and other crypto currencies and is essentially the successor of the Antminer Z9 from the last year that offered 40 KSol/s and the Antminer Z9 mini that was just 10 KSol/s. The Antminer Z11 uses Bitmain’s latest proprietary 12nm chip, which is made using advanced Bare Die molding technology for better heat dissipation and has a power-efficiency of 10.50 J/KSol, so it is with significant improvement over the older hardware. The recommended power supply for this miner is 1800W, though the actual like the APW7 PSU from Bitmain, though the actual power consumption is lower (1418 W power consumption claimed). The current price of the Antminer Z11 is $1242 USD and shipping should start around the end of April (20-30).

New GMiner v1.36 With Improved CPU Usage For Cuckoo Cycle and GPU Intensity Control

15 Mar
2019

The latest GMiner 1.36 miner comes with significantly decreased CPU usage for cuckoo cycle algorithms for Nvidia GPUs (up to 40%), so it should handle better on mining rigs with lower-end CPUs. The new version also has added adaptive CPU usage adjustment for cuckoo cycle algorithms (increase hashrate on weak CPUs), do note that the miner need a few minutes to adapt CPU usage on a weak CPU. There is also an added option to control the GPU intensity (--intensity, 1-100) with the default intensity being 100, but lowering it may be useful for some mining rigs that have stability problems with the highest intensity.

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 and Beam’s Equihash 150,5). 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.

RHminer RandomHash CPU and Nvidia GPU Miner for PascalCoin (PASC)

13 Mar
2019

If you are looking to mine PascalCoin (PASC) on your crypto mining hardware you need to check out the RHminer for the RandomHash algorithm. The miner is open source with official binaries available fo Linux and Windows for different CPUs as well as for more-recent Nvidia GPUs. The current implementation of rhminer for the RandomHash algorithm does manage to provide faster performance on a more recent CPU than on Nvidia GPUs, the faster the CPU and the more the cores you have – the higher performance you will get. Still there is work being done to further optimize Nvidia GPU performance (currently supported are Kepler, Maxwell, Pascal and Volta architectures with their own binaries). By default the official binaries are with 1% developer fee built-in, though you can compile from source with no dev fee if you want to have that removed.

There is another interesting alternative to maximize the performance of your GPU mining rigs if you use the Nanominer for GPU mining and at the same time for RandomHash CPU mining as the miner supports this kind of dual mining mode. Of course this solution will be better if you have a more powerful CPU and not a slow Celeron processor as this may actually hinder GPU performance in some cases if you try to dual mine… still it won’t hurt to give it a try.
