  • Overclocking: Dual CPU systems can be overclocked to achieve even higher performance, but this should only be attempted by experienced users who understand the risks and proper overclocking techniques.

Following these optimization measures will help ensure stability and maximize the performance of a dual CPU system.

Cost Considerations

Dual CPU motherboards and the associated components can be more expensive compared to single-CPU configurations. The cost of the additional CPU, memory, and power supply should be taken into account when planning a dual CPU system. While the benefits of increased performance and scalability may outweigh the cost for professional applications, it is important to evaluate the specific needs and budget constraints before investing in a dual CPU setup.
