Intel SL7J5 Pentium 4 2.8 GHz 1 MB L2 800 MHz FSB LGA 775 switch module

SKU CH-6G1C-DC174

A 2.8 GHz Pentium 4 processor with 1 MB L2 cache and 800 MHz FSB for LGA 775 sockets

  • 8 GHz clock drives responsive single-threaded performance
  • 1 MB L2 cache keeps frequent data close to the core
  • 800 MHz front-side bus moves data quickly to the chipset
  • LGA 775 socket fits compatible desktop motherboards

Pentium 4 processor for LGA 775 socket

This Intel Pentium 4 operates at 2.8 GHz with 1 MB L2 cache and an 800 MHz front-side bus. It fits the LGA 775 socket and is supplied as the processor only. The unit weighs 5.1 and measures 7.5 by 5.3 by 1.

Not for multi-core workloads or modern chipsets

This single-core CPU cannot meet the needs of buyers who want multi-threaded performance or support for current memory and bus standards. It requires a legacy LGA 775 motherboard and matching cooling. It frees up budget for maintaining older systems that depend on this specific socket and bus combination.

Questions about this item

How long can the Pentium 4 2.8 GHz run at full load before thermal throttling reduces its speed?

The processor operates at a 2.8 GHz base frequency with an 800 MHz FSB. Sustained full-load runtime before throttling depends entirely on the cooler and case airflow you pair with the LGA 775 socket.

What noise and heat should I expect from the Pentium 4 2.8 GHz when it runs continuously in a server chassis?

The CPU itself has no integrated fan; acoustics and thermals are determined by the heatsink and chassis fans you install. Power draw scales with the 2.8 GHz core and 800 MHz front-side bus under load.
