Compatibility

Information on Mobile Pentium II 266 compatibility with other computer components and devices: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.

Power consumption (TDP)

10.3 Watt

of 500 Watt (Xeon 6960P)
