What the Celeron 450 is

The Intel Celeron 450 is a 2.2 GHz single-core value desktop processor from August 2008. It runs one Core core at 2.2 GHz with no turbo, so 1 core gives 1 thread. Cache is 512 KB of L2 on a 65 nm process. Power is rated at 35 W on LGA 775.

The 450 tops the Conroe-L single-core line in stepping A1 on an 800 MT/s bus, giving office towers Core-architecture speed at a low envelope. It exists because Intel kept a single-core Celeron for the cheapest desktops while dual cores took over the mainstream. Launch timing rests on the task list.

Socket and motherboard compatibility

The 450 drops into LGA 775 boards with DDR2 or DDR3 memory and a BIOS that lists Conroe-L Celerons, such as G31 boards. Board support lists confirm the 2.2 GHz 800 FSB 512 KB part on LGA 775. 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 35 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 E1200 at 1.6 GHz for a second core at 65 W, or the Intel Celeron E1400 at 2.0 GHz. Beyond LGA 775 a move to a newer platform needs a new board and memory.
