It offers additional features, such as support for the PCI 2. Other than these items, the GX is essentially the same as the BX. Although the E supports dual processors, few, if any, dual-processor E motherboards were ever built. Although the Profusion chipset itself has been discontinued, an improved version of the chipset was developed by Compaq now owned by Hewlett-Packard for use in servers using the Xeon MP processor. The success of the BX chipset has caused various software emulation and virtualization packages to use it as part of their virtual system. 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.

Intel BX – Chipset Guide

QPA combines enhanced bus arbitration, deeper buffers, open-page memory architecture and ECC memory control to improve system performance. It is also known as the iBX and was released in April See All Related Store Items.

The BX became one of Intel’s most popular chipsets. The following sections examine the server-class chipsets for P6 processors up through the Pentium III.


Intel designed the FX to be a lower-cost and somewhat higher-performance replacement for the KX workstation chipset. The chipset includes the Advanced Configuration and Power Interface ACPIallowing quick power down and up, remote start-up over a LAN for remote network management, cadrbus temperature and fan speed sensors.

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

When the LX was introduced, the FX was quickly superseded. However, this chipset was never designed with the Pentium II in mind, whereas the newer LX was optimized specifically to take advantage of the Pentium II architecture.

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 chipset does not support AGP because high-end video is not an issue in network fileservers.

Still, the later i was considered the best Pentium III chipset because it offered a better feature set and very similar performance relative to the BX. The most important feature of the LX is support for 440bc Accelerated Graphics Port AGPa new, fast, dedicated bus designed to eliminate bottlenecks between the CPU, graphics controller and catdbus memory, which will aid fast, high-quality 3D graphics.

Therefore, cache characteristics for these machines are not dependent on the chipset but on the processor instead.

Views Read Edit View history. Although Corollary began developing the Profusion chipset inthe first systems that used Profusion 404bx not released until lateafter Intel carxbus Corollary in latemaking it a wholly owned subsidiary, and released the chipset to server developers in June Photograph used by permission of Intel Corporation.


The BX was a popular one-way and two-way server chipset cadrbus and into Note Quad flat pack QFA is a method used for surface-mounting a chip to a board. The FX uses half the number of components that the previous Intel chipset used.

Intel BX – ThinkWiki

Two versions are available: The official part number is BX. ECC memory support delivers improved reliability to business system users. The LX’s design was flexible enough to support all types of Pentium II systems, from two-way servers to desktop computers.

January Learn how and when to remove this template message. Two dedicated PCI expander bridges can be connected via the expander cardbu. The FX consists of a two-chip North Bridge.

One supports a single processorand the other supports two processors DPmaking the E suitable for use in low-end two-way servers. Up to 8GB of memory is supported in total. Retrieved from ” https: With footprint compatibility with the BX, the ZX is intended to allow OEMs to leverage BX design and validation investment to produce new systems to meet entry level market segment needs.
