The Intel Xeon X5482 was a server/workstation processor with 4 cores, launched in November 2007. It is part of the Xeon lineup, using the Harpertown architecture with Socket 771. To further increase overall system performance, up to two Xeon X5482 CPUs can work together in a multi-processor (SMP) configuration. Xeon X5482 has 6 MB of L2 cache and operates at 3.2 GHz. Intel is building the Xeon X5482 on a 45 nm production process using 820 million transistors. The multiplier is locked on Xeon X5482, which limits its overclocking capabilities. With a TDP of 150 W, the Xeon X5482 is extremely power hungry, which means you need excellent cooling solutions. Intel's processor supports DDR2 and DDR3 memory with a dual-channel interface. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). For communication with other components in the system, Xeon X5482 uses a PCI-Express N/A connection. This processor lacks integrated graphics, so a dedicated graphics card is required. Hardware virtualization is available on the Xeon X5482, which greatly improves virtual machine performance. The processor does not support Intel Hyper-Threading technology, so the thread count remains at 4 threads.
