Socket 478 Pentium 4 processor

This Intel Pentium 4 runs at 2.8 GHz with 512 KB L2 cache and a 533 MHz front-side bus. It fits Socket 478 (FC-PGA2) motherboards and is sold as a processor only without a cooler. The unit weighs 5.1 grams and suits legacy desktop repairs or period-correct retro builds.

Compatibility checks before ordering

Confirm your motherboard uses the Socket 478 (FC-PGA2) interface and supports a 533 MHz front-side bus. Verify the BIOS recognises a 2.8 GHz Pentium 4 with 512 KB L2 cache. Ensure you have a compatible cooler and thermal paste because none are included. Buyers who need a different socket or higher bus speed cannot use this CPU.

Questions about this item

Does the Pentium 4 2.8 GHz processor include a heatsink or fan in the box?

The supplier title lists this as a processor only, so a compatible Socket 478 cooler must be purchased separately.

Should I choose this 533 MHz FSB model or a different front-side bus speed for my Socket 478 motherboard?

Select the 533 MHz FSB version only if your motherboard specifically supports that bus speed; otherwise the processor will not function correctly.
