NPMiner 1.0.91 Released
NPMiner 1.0.91 is now available. This release focuses on two practical fixes reported from real mining rigs.
- Fixed a HiveOS CPAY mining bug affecting NVIDIA RTX 50-series GPUs.
- Added the optional
--prl-cpu-cooldown <ms>parameter for Pearl CUDA mining.
--prl-cpu-cooldown <ms>: Pearl CUDA CPU cooldown in milliseconds between GPU filter-event polls [default: 0]. Value 0 disables the cooldown and actively polls the GPU filter event. Higher values can reduce CPU usage, but may reduce Pearl hashrate or increase stale/late shares. This option is Pearl-specific and experimental; use at your own risk.
Downloads and package notes are available on the NPMiner downloads page.
Thanks: our appreciation to @ivchobow for steering attention to the right edge cases, running the extra rig checks, and keeping the feedback loop grounded in real hardware.
Pearl (PRL) mining on NushyPool has moved from the old Pearl PPS pool to the new FPPS payout system.
For miners, the practical benefit is a smoother payout experience: accepted Pearl work can be credited to your FPPS balance without needing to wait for NushyPool to find a Pearl block during that exact mining period.
This reduces the day-to-day impact of pool block luck for Pearl miners. Your rig still mines the same Pearl pool endpoint, and the public Pearl pool port remains 40015. Pearl Solo mining remains available separately on 45015.
FPPS is currently available only for Pearl (PRL) on NushyPool while we continue monitoring the system with real pool data and real miners.
For a simple explanation of PPS, FPPS, and Solo payouts, read the NushyPool payout systems guide.
NPMiner now includes experimental Pearl (PRL) support for CUDA mining on NushyPool.
Pearl basics: Algorithm: pearl / PearlHash | Pool port: 40015 | Solo port: 45015 | NushyPool devfee: 0%.
Caution: Pearl support is experimental. Optimal performance is currently available only on NVIDIA Ampere / RTX 30-series GPUs. Support for other GPU architectures is coming soon.
Download packages and setup notes are available on the NPMiner downloads page. For pool setup examples, see the Pearl mining guide.
This is the first public npminer Pearl path, so real-rig feedback is especially useful. Please report GPU model, driver version, pool endpoint, accepted/rejected shares, and observed hashrate when testing.
NPMiner is now fully integrated with mmpOS and has a dedicated miner page on Hashrate.no.
Miners can use the mmpOS workflow for deployment and monitoring, and the Hashrate.no page gives an easy reference point for NPMiner setup and visibility.

Credits: special thanks to @ivchobow, @LoonieTunes, and @hashrate.no for the recommendations, support, and help making this integration available to miners.
Thank you to everyone who helped move NPMiner closer to the tools miners already use every day. Good integrations save time on real rigs, and that practical feedback matters.
NPMiner 1.0.8 is now available. This release keeps the focus on practical stability and small performance gains for miners running real rigs.
Download and setup notes: NPMiner downloads.
- Minor CapStash optimization for a small hashrate improvement.
- Fixed HiveOS pool URL input handling so pool URLs can now be entered with
grpc://,stratum+tcp://, orrpc://schemes. - Improved diagnostics for the CPAY issue on HiveOS when using NVIDIA RTX 50xx cards.
Thank you to every miner who keeps testing, reporting, and tuning on real hardware. Your practical feedback helps us keep NPMiner cleaner, faster, and more reliable release by release.
NPMiner now includes experimental CapStash support.
CapStash can be mined with --algo capstash using CUDA or OpenCL. The miner supports compatible Stratum pools and solo direct-node mining through rpc://host:port. This support is experimental for now: we are evaluating miner interest, and if demand is strong enough, NushyPool may launch a dedicated CapStash pool.
- Fixed the startup error message when running the miner on pure AMD rigs without NVIDIA drivers.
- Added diagnostic information when NVIDIA RTX 50xx GPU initialization fails on HiveOS.
Download and setup examples are available on the NPMiner downloads page.
Special thanks: Thank you to @ivchobow for the recommendations, ideas, and testing.
To every miner testing NPMiner on real hardware: thank you. We build and mine too, so the details that matter after long hours on a rig matter to us as well: stable startup, clear diagnostics, low CPU usage, and predictable mining behavior.
