Dual processor motherboards have two sockets for holding two separate processors. They increase the computer's speed and processing power and allow it to handle more tasks. They are commonly used in high-end applications such as servers, graphics, and computer-aided design (CAD). They are seldom used in personal computers, because dual-core processors offer a cheaper and more compact alternative. Most models work with different processors and random access memory (RAM) types.
Types of Dual Processor Motherboards
Kinds of Dual Processor Motherboards include the following:
Synchronous dynamic RAM (SDRAM) motherboards
These motherboards respond to input and transfer data every full clock signal, including the signal's rise and fall.
This process often results in latency, or periods of inactivity in the memory, which slows down operation and causes power wastage. Double data rate (DDR)-SDRAM motherboards
These motherboards respond and transmit data at both the rising and falling parts of the signal. They have less latency and process twice as fast as SDRAM systems.
Maximum processor speed: Make sure your dual processor motherboard can handle the combined speed of the two processors. Most motherboards have a maximum speed indicated on the packaging. Choose one with a high limit if you plan to upgrade processors.
Slots: Choose a dual processor motherboard with room for all your expansion cards and add-ons. Make sure the PCI rack has several extra slots, since this is where most accessory cards are mounted.
