Intel Celeron D 350 socket: Socket 478

What the Celeron D 350 is

The Intel Celeron D 350 is a 3.2 GHz single-core value processor from June 2005. It runs one NetBurst core at 3.2 GHz with no Hyper-Threading, so 1 core gives 1 thread. Cache is 256 KB of L2 on a 90 nm process. Power is rated at 73 W on Socket 478.

The 350 served late Socket 478 value towers on a 533 MT/s bus with a 24x multiplier at about 127 dollars launch price. The cpu_list 84 W value differs from the table 73 W, and the table value is used here. It exists because value buyers wanted a 3.2 GHz Celeron on Socket 478 boards without moving to LGA 775.

Socket and motherboard compatibility

The 350 drops into Socket 478 boards with DDR memory and a BIOS that lists late Prescott Celeron parts. It does not fit LGA 775 boards despite the shared Celeron D name. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is DDR through the board chipset.

A 533 MT/s front side bus ties the CPU to the chipset. AGP slots hang off the chipset.

Cooling is any 73 W rated Socket 478 heatsink on the 478 bracket.

Upgrade paths

On Socket 478 the upgrade stays within Prescott Celeron D, as the 350 tops the 478 line. The Intel Celeron D 352 at 3.2 GHz moves to LGA 775 with 512 KB of cache. Beyond Socket 478 a move to LGA 775 needs a new board and memory.
