front side bus

The front side bus (FSB) is a legacy computer architecture component that connects the CPU to the memory controller and other system components. On WindowsForum.com, discussions about the front side bus often arise in the context of determining compatible RAM speeds for older motherboards, such as AM3+ models supporting DDR3 memory. Users ask whether to base RAM speed selection on the FSB frequency or the memory standard supported by the motherboard. These threads typically involve troubleshooting hardware compatibility, overclocking considerations, and understanding how FSB speed relates to memory bandwidth. While modern systems have moved away from FSB in favor of direct memory access, the term remains relevant for users maintaining or upgrading older Windows-based PCs.
