HPE Xeon E5520 2.26 GHz Processor
This HPE Xeon E5520 is a quad-core server processor upgrade running at 2.26 GHz with a 2.53 GHz overclocking speed. It uses a 45 nm manufacturing process and fits Socket B LGA-1366. The unit includes 1 MB L2 cache and 8 MB L3 cache with 64-bit processing support. QuickPath Interconnect operates at 5.86 GT/s.
Suitable for compatible HPE server maintenance
This processor suits administrators upgrading or repairing existing HPE servers that accept the Xeon 5500 series in an LGA-1366 socket. It is not for builders assembling new platforms or buyers needing newer instruction sets, higher core counts, or different socket types. The part serves as a direct replacement for the 490073-001 part number in supported systems.
Four cores with 8 MB shared L3 cache
The four cores and 8 MB L3 cache handle typical legacy server workloads such as virtualisation hosts, database nodes, or application servers within the thermal envelope of the original platform. Headroom is limited by the 2.26 GHz base frequency and 5.86 GT/s interconnect when compared to modern multi-socket designs. Workloads demanding higher memory bandwidth or newer instruction extensions will exceed practical limits.

Questions about this item
Does my server need an LGA-1366 socket to accept this Xeon E5520?
Yes, the processor upgrade is built for Socket B LGA-1366, so the host system must provide that exact socket.
Will the 5.86 GT/s QuickPath Interconnect work with older Xeon 5500 series processors already installed?
The 5.86 GT/s QuickPath link matches the 5500 series specification, allowing coherent operation alongside same-generation CPUs.
How can I verify the 2.26 GHz base clock and 2.53 GHz turbo are active after installation?
Check BIOS or OS CPU-frequency readouts; they should report 2.26 GHz base and show 2.53 GHz under load when thermal headroom exists.
