Compatibility
Information on Xeon X5650 and Xeon E5620 compatibility with other computer components: 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.
