The 64-bit Xeon 5100 series two-core processor runs at a maximum frequency of 3.0 GHz with 4 MB of shared L2 cache and a maximum front-side bus speed of 1333 megahertz (Figure 7 right). The Xeon 5000 Sequence as well as the 5100 and 5200 series processors use the Intel 5000 series chipsets. These chipsets contain two main components: the Memory Controller Hub (MCH) and the I/O controller hub. The new Northbridge MCH supports DDR2 Fully-Buffered DIMMs (dual in-line memory modules). Figure 7.

The Xeon 5300 series processor has two dual-cores. Each pair of cores shares a L2 cache; up to 4 MB of L2 cache can be allocated to one core. The processor runs at a maximum frequency of 3.0 GHz, with 2 MB of L2 cache per core. This configuration delivers a significant increase in processing capacity utilizing the Intel 5000 series chipsets. ProLiant 300 series servers use the Intel 5000P and 5000Z chipsets. These chipsets support 1066-MHz and 1333-MHz Two Independent Buses, DDR2 FB-DIMMs, and PCI Express I/O slots. The four-core Xeon 5400 series processor (Harpertown) has two dual-cores, and each pair shares a 6-MB L2 cache. The Xeon 5400 series processor runs at a maximum frequency of 3.0 MHz with a 1333 MZ or 1600 MHz FSB. Figure 8. Intel Xeon 5300 and 5400 series processors contain two dual-core chips. 13
