1. CPU and Motherboard Compatibility

The CPU (Central Processing Unit) and motherboard are the PC’s foundation. Here’s what to consider:

• Socket Type (Image of LGA 1700 and AM5 sockets): CPUs fit specific sockets. For example, Intel’s 12th, 13th, and 14th Gen Core processors require an LGA 1700 motherboard, while AMD’s Ryzen 7000 series needs an AM5 motherboard. Using an incompatible CPU can damage both components.
• Chipset: The motherboard chipset supports specific CPU features. Higher-end CPUs benefit from chipsets with overclocking capabilities (like Intel Z790 or AMD X670) and more PCIe lanes for multiple GPUs or NVMe drives. Mainstream chipsets (like Intel B760 or AMD B650) offer lower prices but lack these features.
• BIOS Version: Older motherboards may need a BIOS update to support newer CPUs. Check the motherboard manufacturer’s website for CPU support lists and BIOS update instructions. For instance, an older B660 motherboard might require a BIOS update for 13th-generation Intel CPUs.
• TDP (Thermal Design Power): This represents the amount of heat the CPU generates. The CPU cooler must be able to handle the CPU’s TDP. Refer to the “Cooling Solutions” section for more information.
• Thermal Throttling: CPUs can reduce their performance (thermal throttling) to prevent overheating. This is often caused by insufficient cooling or poor airflow. Ensure your cooler and case provide adequate cooling to prevent performance drops.
• CPU Cooler Compatibility: It’s important to ensure your chosen CPU cooler is compatible with the motherboard socket. Some coolers might require specific mounting brackets that are compatible with the motherboard socket. Check the cooler manufacturer’s website for compatibility information.
