14-429: The divergence was implemented by using different sockets; since then, the sockets for Xeon chips have tended to remain constant across several generations of implementation. The chipsets contain a 'memory controller hub' and an 'I/O controller hub', which tend to be called 'north bridge' and 'south bridge' respectively. The memory controller hub connects to the processors, memory, high-speed I/O such as PCI Express, and to

28-612: Is used by the Tigerton and Dunnington processors. The 3450 chipset is also compatible with an Intel Core i5 or Intel Core i3 processor. The Nehalem-based Xeons for dual-socket systems, initially launched as the Xeon 55xx series, feature a very different system structure: the memory controllers are on the CPU, and the CPUs can communicate with one another as peers without going via the chipset. This means that

42-729: The Intel Xeon E3-1200v5 CPU family. Both, the C232 and the C236 support the LGA 1151 socket. The Intel C246 series chipsets support the Intel Xeon E-2100 series of CPUs. h Slot 2 Slot 2 refers to the physical and electrical specification for the 330-lead Single Edge Contact Cartridge (or edge-connector) used by Intel 's Pentium II Xeon and Pentium III Xeon . When first introduced, Slot 1 Pentium IIs were intended to replace

56-467: The Pentium and Pentium Pro processors in the home, desktop, and low-end symmetric multiprocessing (SMP) markets. The Pentium II Xeon, which was aimed at multiprocessor workstations and servers, was largely similar to the ordinary Pentium II, being based on the same P6 Deschutes core, differing by offering the choice of L2 cache capacity of 1024 or 2048 KB besides 512 KB, and by operating it at

70-591: The 5500 and 5520 (initial codename Tylersburg-EP) chipsets are essentially QPI to PCI Express interfaces; the 5520 is more intended for graphical workstations and the 5500 for servers that do not need vast amounts of PCI Express connectivity As well as the 5530 The Intel C200 series chipsets that support the Intel Xeon E3-1200 CPU family. The Intel C600 series chipsets support the Intel Xeon E5-2600 CPU family. Common to all C600 variants are

84-507: The E7230 chipset, codenamed Mukilteo, which has specifications very similar to the 3000 chipset. E7230 was preceded by E7221, which was Intel's first strictly single-socket server chipset. These chipsets use a ' dual independent bus ' design, in which each socket has its own connection to the chipset. These use the LGA 771 socket. The datasheets omit the 667 MT/s FSB support, so 5400 may support it too. This chipset uses four independent buses, and

98-483: The I/O controller hub by a proprietary link. The I/O controller hub, on the other hand, connects to lower-speed I/O, such as SATA, PCI, USB, and Ethernet. Intel's initial preferred chipset for Pentium III Xeon was the 840. The Pentium III Xeon bus protocol allowed four processors on the same bus, so the 440GX AGPset could be used in four-CPU systems; the limit of 2 GB of main memory remained. These support Slot 2 . There

112-571: The Profusion PCIset. The chipset was based on technology developed by the Corollary company, which Intel acquired. It supported up to 8 Pentium III Xeon processors on two busses and maintained cache coherency between them. Profusion supported up to 32 GB of memory. It saw some limited competition from the NEC Aqua II chipset. Another minor player in the eight-way space was Axil Computer's NX801, which

126-474: The core frequency (the Pentium II used cheaper third-party SRAM chips, running at 50% of CPU speed, to reduce cost). Because the design of the 242-lead Slot 1 connector did not support the full-speed L2 cache of the Xeon, an extended 330-lead connector was developed. This new connector, dubbed 'Slot 2', was used for Pentium II Xeon (codenamed 'Drake') and Pentium III Xeon (codenamed 'Tanner' and 'Cascades'). Slot 1

140-649: The following features: Some chipset variants have additional mass storage interfaces: The Intel Communications 8900 series chipsets that support the Gladden Intel Xeon E3-11xx or Sandy Bridge-EP/EN Intel Xeon E5-2xxx CPU families. The Intel C200 series chipsets that support the Intel Xeon E3-1200v2 CPU family. The Intel C220 series chipsets support the Intel Xeon E3-1200v3 CPU family. The Intel C230 series chipsets support

154-560: Was also the 450NX PCIset, which consisted of several chips: a single 82451NX Memory and IO Bridge Controller roughly analogous to the North Bridge, up to two 82454NX PCI Expander Bridges which converted the protocol used by 451NX to two 32-bit PCI33 or one 64-bit PCI33 bus, along with up to two memory cards each equipped with one 82452NX RAS/CAS Generator chip and two 82453NX Data Path Multiplexer chips. It supported PIIX3 and PIIX4E south bridges, and EDO DRAM. In August 1999 Intel began shipping

168-480: Was finally replaced by the Socket 370 with the revised Pentium III codenamed Tualatin for the low power dual-processor servers, and Slot 2 by Socket 603 with Pentium 4 -based Xeon (codenamed Foster) for workstations and quad-processor servers. This computer hardware article is a stub . You can help Misplaced Pages by expanding it . List of Intel Xeon microprocessors#⁘Gladden⁘ (32 nm) The following

182-425: Was used in an 8-way (two buses) Pentium Pro design, commercialized by Data General as their AV-8600 computer. E7500 corresponded to the first Northwood-based Pentium4 Xeons, E7501 is essentially identical but supports faster FSB and memory. The E7320, E7520 and E7525 chipsets correspond to Prescott-based Pentium4 Xeons, and differ mainly in their PCI Express support. These support Socket 604 . The Intel 875P chipset

196-621: Was used in some two-socket motherboards for Xeons. Note that the 82870P2 chips of E7500, E7501 and E7505 were initially designed for the Intel 870 chipset for Itanium 2, and that the summary page of the E7320 datasheet incorrectly claims three PCI Express interfaces. As Intel didn't have a 4P-capable chipset for NetBurst-based Xeons until 2005, for three years ServerWorks GC-HE served as the de facto standard MP chipset, even being used in Intel's own motherboards (SPSH4 and SRSH4). 3000 and 3010 are an update on
