Intel Celeron 1400 socket: Socket 370

What the Celeron 1400 is

The Intel Celeron 1400 is a 1400 MHz single-core value processor from May 2002. It runs one P6 Tualatin core at 1400 MHz with no Hyper-Threading, so 1 core gives 1 thread. Cache is 256 KB of L2 on a 130 nm process. Power is rated at 35 W in a Socket 370 FC-PGA2 package with a 100 MHz front side bus and a 14x multiplier.

The 1400 tops the Tualatin Celeron line with the highest clocks and power in the group. Intel placed it in May 2002 after the 1300 from January 2002. The chip supports MMX and SSE. Pentium III Tualatin 1400 parts at the same 1400 MHz offer 256 KB with a 133 MHz bus as a mainstream alternative, so bus speed separates value from mainstream at identical frequency.

Top value clocks with a slow bus suited budget towers that needed megahertz for single-task use. The 35 W envelope needs only a modest Socket 370 cooler. That is why the 1400 remained a common used-market target for blue Tualatin boards.

Socket and motherboard compatibility

The Celeron 1400 fits Socket 370 blue Tualatin boards with a 100 MHz bus. It needs FC-PGA2 support. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Budget SDRAM towers are the natural match. Boards listing Tualatin 1400 accept the chip with a 35 W cooler.

Memory, PCIe and cooling

Memory is SDRAM through the board chipset. The board sets speed and capacity.

A 100 MHz bus ties the CPU to the chipset, while AGP and PCI hang off the chipset. No PCIe lanes originate on the die. Cooling uses the Socket 370 lug with a 35 W heatsink.

Upgrade paths

On Socket 370 the 1400 tops Tualatin Celeron, so same generation upgrades stop here. Pentium III Tualatin parts offer larger cache as a lift. Beyond Socket 370 a move to Socket 478 needs a new board. The 1400 lifts with the lever, so swaps need no solder work.
