New lolMiner 0.9.7 OpenCL GPU Miner With Cuckatoo 32 Improvements

29, Jan 2020

The latest update of the AMD OpenCL GPU miner lolMiner 0.9.7 brings nice performance boost for the Cuckatoo 32 algorithm for GRIN s well as a GRIN Auto profit switching functionality on some pools (2Miners, BTC.com, F2Pool and Grinmint). Windows users can expect to get 15-18% performance boost for GRIN-C32 on AMD Navi cards and Linux users can expect to get 15-18% boost for GRIN-C32 performance on AMD Vega, VII and Navi cards. AMD Radeon RX 580 8GB GPUs are also supported forC32, however performance is nothing to brag about at just about 0.13 G/s on Windows currently. lolMiner was the first AMD GPU miner for 8GB cards with experimental support for C32 and each new version has been improving stability and performance.

Expected Performance for Grin C32:

- Card - Windows - Linux
- Radeon VII: 0.65 g/s - 0.77 g/s
- Vega 64: 0.42 g/s - 0.49 g/s
- Vega 56: 0.36 g/s - 0.42 g/s
- RX 5700: 0.4 g/s - 0.4 g/s

The primary Grin proof of work Cuckatoo 31+ is designed in a way that the original instance – Cuckatoo-31 – will fade out beginning mid January 2020, which means its difficulty will increase slowly over a period of 31 weeks until it gets impossible to mine a C31 block on the chain. But as by design also more difficult instances of Cuckatoo, namely Cuckatoo-32 … Cuckatoo-63 are implemented on the chain that also can make blocks. The difficulties of this higher instances will remain stable, such that at some point it will be more profitable to mine Cuckatoo-32 instead of Cuckatoo-31 (likely from mid of February).

We remind you that lolMiner is a closed source OpenCL GPU miner available for Windows and Linux as pre-compiled binaries only and that there is a 1% developer fee for using the software for all supported algorithms. The miner should work on Nvidia GPUs with OpenCL, however stability and performance could be far from optimal, so it is best for use with AMD GPUs.

New lolMiner 0.9.2 OpenCL GPU Miner With More Cuckatoo 31 Improvements

3, Dec 2019

The latest update of the AMD OpenCL GPU miner lolMiner 0.9.2 brings some extra performance boost for the GRIN-AT31 (Cuckatoo 31 algorithm) on 8GB and 16GB video cards of up to +5% on AMD Polaris and AMD Vega GPUs and up to +10 on AMD Navi GPUs. The latest version also adds experimental support for GRIN-AT31 and Polaris, Vega and VII using AMD ROCm drivers under Linux. The lolMiner 0.9.2 has added range checks to GRIN-AT31 code for improved stability as well as added function to call external watchdog scripts in case a GPU fails during mining (if the miner detects no action of a GPU for at least a minute it will call the included reboot scripts).

Grin C31 lolMiner 0.9.2 expected hashrates:
– AMD Radeon VII (stock): 1.79 G/s
– AMD Radeon VII (1340/1000/0.825v, 130W): 1.37 G/s
– AMD Vega FE (stock): ~1.3 G/s
– AMD Vega 56 (1220/900/0.825v, 130W): 1.0 G/s
– AMD RX 5700 (Red Dragon, stock): 0.91 G/s
– AMD RX 580 8GB: 0.56 G/s

We remind you that lolMiner is a closed source OpenCL GPU miner available for Windows and Linux as pre-compiled binaries only and that there is a 1% developer fee for using the software for all supported algorithms. The miner should work on Nvidia GPUs with OpenCL, however stability and performance could be far from optimal, so it is best for use with AMD GPUs. For Nvidia GPU miner with support for Cuckatoo 31 you can check out the latest GMiner, NMBiner or some of the other option like BMiner etc.

New lolMiner 0.9 OpenCL GPU Miner With Cuckatoo 31 Performance Boost

20, Nov 2019

The latest update of the AMD OpenCL GPU miner lolMiner 0.9 brings significant performance boost for the Cuckatoo 31 algorithm used by Grin on 8GB AMD cards (+22% on Polaris and up to 30% on Radeon VII) and reduced Grin stale shares. The new version also has the 16GB solver for GRIN-AT31 disabled as it seems that the 8GB solver is faster at the moment in terms of hashrate. Do note that currently AMD Navi support is disabled for the new algorithms and Cuckatoo-31 on ROCm drivers falls back to 4GB kernel.

Expected performance on Cuckatoo-31 (stock settings):
– Sapphire RX 580 Pulse 0.55 g/s
– Radeon Vega 64: 1.2 g/s
– Power Color Radeon VII 1.53 g/s
