Although both are commonly known as Orion, the KX was originally known as Mars. Finally, the unsupported Tualatin-core Pentium III could be used with an adapter and various modifications, with varying degrees of success. From late through , the Profusion chipset was the leading eight-way server chipset used with Intel server-class processors. Views Read Edit View history. This page was last edited on 11 April , at

When the LX was introduced, the FX was quickly superseded. Therefore, cache characteristics for these machines are not dependent on the chipset but on the processor instead.

Intel 440BX

This eight-way server used two NX chipsets linked by Fujitsu’s Synfinity interconnect technology and non-uniform memory access NUMA memory architecture to create what is, in effect, a tightly coupled computer cluster in a single unit. The FX uses half the number of components that the previous Intel chipset used. However, the greater complexity of four-way and larger multiprocessor server architectures using Intel processors requires the use of several specialized chips.

The success of the BX chipset has caused various software emulation and virtualization packages to use it as part of their virtual system.

Intel Chipsets – LX, EX, BX, ZX, GX

The official part number is BX. Profusion’s design, originally developed by Corollary in cooperation with Compaq cardbuz a Hewlett-Packard brandis even more sophisticated than the NX’s because of the added challenge of supporting eight processors.

The chipset consists of three main components, with a few optional extras. The following sections examine the server-class chipsets for P6 processors up through the Pentium III. Although both are commonly known as Orion, the KX was originally known as Mars.

The Intel 8xx series chipsets introduced in represent a major departure from the 4xx-series chipsets previously used by Intel for its one-way and two-way servers.

Either is designed to work carcbus the same ICH as used carbus the other series chipsets, such ihtel the and The chipset uses the same hub architecture and modular design as the rest of the family of chipsets, with some additional components that enable more performance. Some vendors, such as ALR, with its Revolution 6×6, designed systems that could use up to six processors using the GX chipset.

This chipset allows for lower-cost, high-performance workstations and servers using the Slot 2—based Xeon processors. Windows software utility to keep the PC operating optimally. This was the first chipset to really take full advantage of the Pentium II processor.

Other than these items, the GX is essentially the same 44bx the BX. Chips that use QFA intek have leads on all four sides of the chip. Although the FX was designed for use in workstation applications, it was also used as a low-end server chipset by numerous vendors.


The crossbar switch and support for multiple PCI bus bridge chips enable servers based on Profusion to handle memory, processor, cache coherency, and PCI bridge failures while continuing to operate. The NX supports one or two memory cards. Still, the later i was considered the best Cadrbus III chipset because it offered a better feature set and very similar performance relative to the BX. Ironically, the BX offered better performance than several of its successors.

Ball grid array BGA chips use solder balls on the underside of the chip. BGA uses less space on a board.

Intel 440 Chipsets – 440LX, 440EX, 440BX, 440ZX, 440GX

Additional products included to assist with maintaining performance include anti … [Read More The chipset also has better integration with the capabilities of the Pentium II, such as support for dynamic execution and processor pipelining. Three additional components shown in Figure 3. Note Quad flat pack Inteo is a method used for surface-mounting a chip to a board.

In addition, single-bit error correction caddbus provided, thereby avoiding server downtime because of spurious memory errors caused by cosmic rays.
