Express overclocking Intel Celeron D 326 to 4560MHz (90nm, Prescott, 2533MHz)

The Intel Celeron D 326 is one of the blue giant's lower-end processors for the LGA 775 platform. This makes it an appealing choice for overclocking, as even if a "patient" CPU should perish, there are plenty more to take its place.

Processor

• PSU — Cooler Master 460W

Overclocking

We managed to overclock the Celeron D 326 to a stable 4005MHz:

This required raising the core voltage to 1.536 volts, increasing the FSB to 210MHz, bumping the FSB voltage to 1.32 volts, and dropping the RAM multiplier by one step.

Due to the modest 1GB of RAM installed in the system, stability testing was performed in Windows XP:

Additionally, we decided to perform a "screenshot overclock" for the HWBot overclocking database.

We set the chip's voltage to around 1.700 volts, the FSB to 240MHz, and its voltage to 1.350 volts, which resulted in a frequency of 4560MHz:

Be careful: raising the core voltage above 1.600 volts can lead to CPU failure.
