Features and applications
Product details
HPE P66239-B21 is a processor option. Processor model: Xeon-Gold 6423N; Processor clock: 2.0GHz; Core count: 28-core; Power rating: 195W.
Choose the correct replacement
Match the exact processor model and generation to the server platform, system firmware, socket population and approved thermal assembly. Similar processor family names do not guarantee interchangeability.
Original ordering code
Use P66239-B21 when comparing parts or placing a request. This ordering code identifies the OEM option; an underlying component manufacturer model is not automatically an equivalent replacement.
Processor generation and installation
Retain the complete model and generation shown in the specifications. Confirm CPU pairing, BIOS support, heatsink and any required installation hardware with the server configuration. A similarly numbered processor from another generation is a different product.
Included items and condition
Specify the requested quantity and condition. We confirm brackets, carriers, cables, thermal parts or other accessories separately. A system name associated with a component does not mean a complete server or storage system is supplied.
Price and delivery
Any displayed USD amount applies to this exact manufacturer P/N as one ordering item. Confirm package contents and quantity, host compatibility, availability, delivery, taxes and the final total before bank transfer.
