Intel Xeon E5345 Quadcore 2.33GHz 8MB L2 1333MHz FSB LGA771 65nm 80W Processor

SKU CH-H55R-177EK

Quad-core Xeon processor running at 2.33 GHz with 8 MB L2 cache and 1333 MHz FSB for LGA 771 servers

  • Quad-core design handles parallel server workloads with 4 cores
  • 33 GHz clock speed drives responsive processing for demanding applications
  • 8 MB L2 cache reduces memory latency for faster data access
  • 80 W thermal design keeps power draw predictable in dense deployments

Intel Xeon E5345 Quad-Core Processor

This Intel Xeon E5345 processor delivers four cores running at 2.33 GHz with 8 MB of L2 cache. It fits the LGA771 socket and operates within an 80 W thermal design power. The 65 nm manufacturing process supports reliable performance in compatible server platforms.

1333 MHz Front-Side Bus Limitation

The 1333 MHz front-side bus sets the maximum data transfer rate between the processor and the system chipset. This bandwidth ceiling restricts overall throughput in memory-intensive workloads. Builders needing higher interconnect speeds must select a platform with a faster bus architecture.

Questions about this item

Should I pick the 2.33 GHz Xeon E5345 or a different clock speed for my LGA771 board?

The E5345 runs at 2.33 GHz with a 1333 MHz front-side bus and 80 W TDP; choose it when your motherboard supports that exact FSB and power envelope.

What does the 1333 MHz FSB figure mean once the processor is installed in a server?

It sets the peak data rate between the CPU and the chipset, so memory and I/O throughput scale with that 1333 MHz bus speed.
