SKU CH-B1M9-5QWH9 MPN E5400Product

Dual-core processor running at 2.70 GHz with 2 MB L2 cache and 65 W TDP for Socket T LGA-775 motherboards

  • Dual-core performance at 2.70 GHz clock speed
  • 2 MB L2 cache for responsive multitasking
  • 65 W thermal design power for efficient cooling
  • LGA-775 socket fits compatible motherboards
  • 45 nm process technology balances speed and power

Pentium Dual-core 2.70 GHz

The Intel Pentium Dual-core E5400 operates at 2.70 GHz with two cores built on a 45 nm process. It fits the LGA-775 socket and has a 65 W thermal design power. This processor suits basic desktop tasks such as office applications and web browsing.

2 MB L2 cache and 800 MHz bus

The chip provides 2 MB of L2 cache and communicates over an 800 MHz front-side bus. This combination handles everyday workloads and light multitasking without difficulty. More demanding software or heavier multitasking will exceed the available headroom.

LGA-775 socket compatibility

Installation requires a motherboard with an LGA-775 socket, also known as Socket T. The processor will not fit any other socket type, so verifying the board is essential before purchase.

Questions about this item

Will the E5400 Pentium Dual-core 2.70 GHz processor fit the LGA-775 motherboard I already use?

Yes, the E5400 uses the Socket T LGA-775 interface, so it installs directly into any compatible LGA-775 board.

How can I verify the E5400 is running at its rated 2.70 GHz clock speed and 800 MHz bus speed after installation?

Enter the BIOS or use a system-information utility such as CPU-Z; both will report the core speed at 2.70 GHz and the front-side bus at 800 MHz.

Does the E5400 box include a heatsink and thermal paste, or must I buy them separately?

The listing states CPU Only, so no cooler or thermal compound is included; you must supply a compatible LGA-775 heatsink and paste.
