NiceHash, a leading name in the crypto mining world, has just launched its first-ever custom firmware for Antminer KS series ASICs, and it’s all about boosting your Kaspa mining game. The firmware promises up to a 20% performance increase, lower power consumption, and built-in thermal protection to prevent overheating. It’s a game-changer for anyone mining on the Kaspa network!
Performance & Efficiency Gains
After real-world testing, the firmware has shown impressive results. Performance can improve by up to 20%, while power consumption drops, making your operations more efficient. The built-in thermal protection will help safeguard your expensive hardware, reducing the risks of damage due to overheating.

Installation Requirements
However, installing this firmware isn’t as straightforward as it might seem. Most Kaspa Antminer models are running CVITech control boards, which don’t allow for persistent custom firmware installations. To get around this, you’ll need to install a Cracker Card. This hardware add-on allows you to upgrade to the NiceHash firmware easily.

Supported Models:
- Antminer KS5 Pro
- Antminer KS5
- Antminer KS3 (9.4 TH)
- Antminer KS3 (8.3 TH)
Dynamic Fee Structure
NiceHash is using a dynamic fee structure based on overclocking levels, with fees ranging from 1% to 4%. You’ll be able to tweak your mining operations to match your performance goals, but fees will increase with higher overclocking levels.
Getting Started
To install the firmware, you’ll need to get your hands on a Cracker Card, which is currently available exclusively to NiceHash users. For smaller mining operations with fewer than 100 machines, these will soon be available for sale directly through the NiceHash shop.
This custom firmware is only available for use with NiceHash’s mining pool, meaning you’ll need to decide if switching to their pool is worth the benefits.
