A ship's CPU is the computer that controls the modules (such as weapons, repair systems, and so on) that you have fitted to your ship. The CPU has limits, and this page explains how to make the most of your ship's CPU.
Your ship has fitting slots that you can use to install modules on your ship. When a module is online (i.e. turned on) it uses some of your ship's CPU power. Because of your ship CPU's limits, you might not be able to have all of your modules online at the same time.
You can increase your CPU output by training the CPU Management skill. It will boost your CPU output by 5% for each level of CPU Management that you train.
There are also skills that allow you to make more efficient use of your ship's CPU, reducing the amount of CPU required by different types of modules that you can fit to your ship. They are summarized below:
You can also add co-processors to your ship to increase CPU output. There are a number of different co-processors available in the market. For example, Co-Processor II boosts CPU output by 10%.
Your character can install neural implants to further increase your CPU efficiency. Implants such as the Zainou 'Gnome' and the Inherent Implants 'Highwall' reduce CPU usage of specific module types.
Just as there are implants for your grey matter “CPU”, there exist a number of rigs that you can use on your ship to reduce CPU usage of modules. For example, the Liquid Cooled Electronics rig will reduce CPU needs of Electronics Upgrades modules.
