Intel Xeon X5355

Enterprise LGA771 Quad-Core Server Processor platform refresh featuring the Intel Xeon X5355 (BX80563X5355A)

The Intel Xeon X5355 is a Clovertown-generation, 65 nm quad-core server CPU designed for maintaining and extending LGA771 infrastructures where platform stability and validated firmware stacks matter. The Intel Xeon X5355 aligns with 2-socket server designs via a 1333 MT/s front-side bus, enabling consistent compute density for legacy racks without forcing a chassis, board, or OS requalification cycle.

Memory is implemented through the chipset and platform memory controller typical of LGA771 systems, with ECC capability dependent on the server board and DIMM population rules. Expansion and storage are likewise governed by the platform’s northbridge/southbridge architecture, making the Intel Xeon X5355 a targeted choice when PCIe lanes, RAID controllers, and existing SAS/SATA backplanes must remain unchanged. With Intel 64, VT-x, and Execute Disable Bit, the Intel Xeon X5355 supports consolidated services and controlled virtualization on older hypervisor baselines where predictable I/O behavior is prioritized over modern instruction-set acceleration.

Why Choose the Intel Xeon X5355?

The Intel Xeon X5355 delivers a practical balance of quad-core throughput and 2-socket scalability for LGA771 fleets that require spare CPUs or standardized refresh parts. For IT teams managing homogeneous server pools, the Intel Xeon X5355 helps preserve operational consistency, thermal envelopes, and validated driver stacks while restoring node capacity with minimal integration risk.

Intel designs Xeon processors with an emphasis on platform compatibility, deterministic behavior under sustained load, and lifecycle continuity for enterprise deployment models. This approach supports controlled maintenance windows and predictable performance within established data centre operational standards.

Key Applications:

Legacy LGA771 server refresh and spares
2-socket virtualization with VT-x
General-purpose compute for legacy services
Infrastructure monitoring and management tooling

At Happyware - Server Hardware you benefit from Non-Binding Offers tailored to your LGA771 refresh scope, helping you standardize on the Intel Xeon X5355 with procurement clarity. For phased rollouts or spares stocking, Bulk Order Discount supports cost-controlled fleet maintenance.
