The Celeron D chosen was the 331, for being the first Socket 775 Celeron to support the EM64T technology, that allows the processor to access more RAM memory, and the XD (eXecute Disable, also known as NX bit) technology, that prevents some kinds of viruses from attacking the PC.
The main characteristics of the Celeron D 331 tested are:
- Socket: 775
- Internal clock: 2.66 GHz
- Memory clock (external clock): 533 MHz (133 MHz QDR)

- Voltage: 1.25 – 1.4 V
- Thermal power: 84 W
- Manufacturing process: 90 nm
- Core: Prescott
- 64-bit extensions enabled
- SSE3 instruction set and eXecute Disable
