Four processor P6-based Xeon chipsets[edit]
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 2GB of main memory remained. These support Slot
2.
There 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.
Eight processor P6-based Xeon chipset[edit]
In August 1999 Intel began shipping the Profusion PCIset.[1]
The chipset was based on technology
developed by the Corollary company, which Intel acquired.[2]
It supported up to 8 Pentium III Xeon
processors on two busses and maintained cache coherency between them.[3][4][5]
Profusion supported
up to 32 GB of memory. It saw some limited competition from the NEC Aqua II chipset.[6]
Another
minor player in the eight-way space was Axil Computer's NX801,[2]
which was used in an 8-way (two
buses) Pentium Pro design, commercialized by Data General as their AV-8600 computer.[7]
NetBurst-based Xeon chipsets[edit]
Dual processor NetBurst-based Xeon chipsets[edit]
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.

Dual processor Nehalem-based Xeon chipsets[edit]
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 the 5500 and
5520 chipsets are essentially QPI to PCI Expressinterfaces; the 5520 is more intended for graphical
workstations and the 5500 for servers that do not need vast amounts of PCI Express connectivity

The Asrock X99 Extreme4 is an ATX motherboard,
measuring 9.60 in. x 12.00 in. It was was designed for
use with an Intel processor that fits in an LGA 2011
(Socket R) socket.
The Asrock X99 Extreme4 features an Intel X99
chipset, which could be considered extreme-
complexity, meaning that it has almost any feature
imaginable on a consumer motherboard. Extreme-
complexity boards are truly top-of-the-line and come
at a higher price point than most motherboards.

The Asrock X99 Extreme4 has eight RAM slots,
which is4 more than average. The RAM in these
eight slots may not exceed 128GB, even if more
RAM sticks can physically fit.
The Asrock X99 Extreme4 is compatible with
DDR4 RAM. This means that the Asrock X99
Extreme4 is an extremely high-end board, utilizing
technology that will not become mainstream until
around the year 2016 or later. Chances are, DDR4
RAM will be very expensive, as will this
motherboard.
The board utilizes Quad-Channel RAM architecture,
which is almost exclusively in Intel LGA 2011
boards.

The Asrock X99 Extreme4 does not support CPU-
based graphics, meaning an external graphics card
(GPU) will be required to use a display. This is
generally the most widely-used graphics solution for
gaming, regardless, as external cards tend to be more
powerful and more suitable for graphics-intensive
tasks such as high-end gaming and film CGI
production.

The Asrock X99 Extreme4 comes with a 7.1-
Channel Realtek ALC1150 sound processor. This
board will also be fully compatible with surround
sound systems and thus, a third-party sound card is
not required. However, it may be something to
consider if the computer is being used for
professional audio production.
