What the Celeron 430 is
The Intel Celeron 430 is a 1.8 GHz single-core value desktop processor from June 5, 2007. It runs one Core core at 1.8 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 430 sits above the 420 in the Conroe-L launch pair in stepping A1 on an 800 MT/s bus. It has no VT-x virtualization or SpeedStep, as is traditional with Celerons. It exists because Intel wanted two single-core steps for buyers choosing between the cheapest desktop chip and the 440.
Socket and motherboard compatibility
The 430 drops into LGA 775 boards with DDR2 memory and a BIOS that lists Conroe-L Celerons, such as 945 and G31 boards. Board support lists confirm the 1.8 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 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.
Upgrade paths
On LGA 775 the upgrade is the Intel Celeron 440 at 2.0 GHz within the Conroe-L line, or the Intel Celeron E1200 at 1.6 GHz for a second core. The Intel Celeron 420 at 1.6 GHz is the cheaper Conroe-L. Beyond LGA 775 a move to a newer platform needs a new board and memory.
