Intel Core 2 Duo E7400

2C/2T · 65 W

The Core 2 Duo E7400 is a mainstream 45 nm Wolfdale-3M dual-core for LGA 775 desktops, introduced in October 2008. It carries half the shared cache of the contemporary E8000 series and runs on a 1066 MHz front-side bus rather than 1333 MHz, which is what separated the two lines on price. The early R0-stepping parts do not support Intel VT-x; Intel later shipped an ML-suffixed part number that enables it.

OS support

Windows: Windows 10
Linux: UbuntuFedoraArch Linux
Notes: Windows 11 is out of reach: the chip is far below the 8th-generation floor on Microsoft's supported-processor list and its platforms offer no TPM 2.0 or Secure Boot. Windows 10 and the mainstream Linux distributions still install, because they are built for the x86-64 baseline, but the CPU has no SSE4.2 or POPCNT, so any software that requires x86-64-v2 or newer will not run. ChromeOS Flex does not cover hardware of this era.
