J7426 - 2.1Ghz 400Mhz 2MB Intel Pentium M 765 CPU Processor

Intel Pentium M 765 SL7V3 - 2.1 GHz 400 MHz 2 MB CPU Processor

The Intel Pentium M 765 (SL7V3) is a single-core Dothan mobile CPU for Socket 479 (mPGA479M/PPGA478). With a 2.1 GHz clock, 2 MB L2 cache, and 400 MHz FSB, it’s a reliable drop-in for many Intel 855-chipset notebook platforms and embedded systems.

Technical Specifications

• Processor Number: Pentium M 765
• S-Spec: SL7V3
• Base Clock: 2.1 GHz
• Front Side Bus: 400 MHz
• L2 Cache: 2 MB
• Core: Dothan, 90 nm
• Instruction Set: MMX, SSE, SSE2
• TDP: ~21 W
• Socket: mPGA479M / PPGA478 (Socket 479)

Interchangeable Identifiers

• ✔ SL7V3 – Pentium M 765, 2.1 GHz, 400 MHz FSB, 2 MB L2
• ✔ Same-model 765 S-specs of the identical core, frequency, cache, and socket (functionally interchangeable)

✔ Confirmed Compatibility

Please note that the following list is not exhaustive. Compatibility depends on BIOS version and chipset support. Always confirm with the motherboard manufacturer before installation.

Lenovo / IBM ThinkPad
✔ ThinkPad T42 and T42p – 855PM/GM chipset
✔ ThinkPad R51 – 855GME chipset

Dell
✔ Latitude D600 – 855PM chipset
✔ Inspiron 600m – 400 MHz FSB platform
✔ Latitude D800 – 855PM mobile workstation platform

HP / Compaq
✔ Compaq nc6000 – 855PM chipset

Embedded and Industrial Boards
✔ Socket 479 motherboards and SBCs using Intel 855GM/855GME chipsets with 400 MHz FSB

Not compatible with systems designed only for 533 MHz FSB Pentium M processors (e.g., many T43, D610, and later platforms).

Key Features

☑ 2.1 GHz single-core Dothan CPU with 2 MB L2 for responsive legacy systems
☑ Low ~21 W TDP for quiet, cool operation in notebooks and SFF builds
☑ Ideal drop-in for 400 MHz FSB 855-class platforms needing a top-end Dothan upgrade

Fit Notes

• Requires Socket 479 (mPGA479M/PPGA478) and a 400 MHz FSB design.
• BIOS update may be required; confirm CPU microcode support before installation.
• Not compatible with 533 MHz-only boards or newer Core-series sockets.
• Ensure proper cooling and always apply fresh Shin-Etsu G751 High Performance Thermal Paste when installing.
