The Intel Xeon X3430 was a server/workstation processor with 4 cores, launched in September 2009, at an MSRP of $189. It is part of the Xeon lineup, using the Lynnfield architecture with Socket 1156. Xeon X3430 has 8 MB of L3 cache and operates at 2.4 GHz by default, but can boost up to 2.8 GHz, depending on the workload. Intel is making the Xeon X3430 on a 45 nm production node using 774 million transistors. The multiplier is locked on Xeon X3430, which limits its overclocking potential.
With a TDP of 95 W, the Xeon X3430 consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1333 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Xeon X3430 uses a PCI-Express Gen 2 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon X3430, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware.
