What the Celeron E1400 is
The Intel Celeron E1400 is a 2.0 GHz dual-core value desktop processor from April 2008. It runs two Core cores at 2.0 GHz with no turbo, so 2 cores give 2 threads. Cache is 512 KB of shared L2 on a 65 nm process. Power is rated at 65 W on LGA 775.
The E1400 stepped the Celeron dual-core line up to 2.0 GHz in stepping M0 on an 800 MT/s bus, keeping the $53 tray price class. It has no VT-x virtualization. Against the E1200 it adds 400 MHz for everyday office and web speed.
Socket and motherboard compatibility
The E1400 drops into LGA 775 boards with DDR2 or DDR3 memory and a BIOS that lists early-2008 Celeron dual cores, such as G31 and G33 boards. It pairs with value 3 series chipsets contemporary with Allendale. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2 and DDR3 through the board chipset in two channels.
An 800 MT/s front side bus ties the CPU to the chipset. PCIe slots hang off the chipset.
Cooling is any 65 W rated LGA 775 heatsink on the 72.5 × 72.5 mm mount, with Enhanced SpeedStep trimming draw at idle.
Upgrade paths
On LGA 775 the upgrade is the Intel Celeron E1500 at 2.2 GHz within the Celeron line, or the Intel Pentium Dual-Core E2220 at 2.4 GHz with 1 MB of cache. The Intel Celeron E1200 at 1.6 GHz is the cheaper Celeron. Beyond LGA 775 a move to a newer platform needs a new board and memory.
