HP xw4550 Workstation - Overview

Featuring the workstation-class, Second-Generation AMD Opteron processor, the HP xw4550 takes advantage of AMD’s Direct Connect Architecture, which includes an integrated memory controller and HyperTransport technology links to accelerate performance of bandwidth and compute-intensive applications. With its convertible minitower design, the HP xw4550 provides an efficient footprint system that was engineered to operate quietly and without distraction. Its simultaneous support for 32- and 641-bit applications, 6 storage bays, 4 DIMM slots and up to 4 GB2 of ECC memory, provides the upgradeability you’d expect from higher-end workstations.
