Chapter 1. Introduction of CX6 Features
1-1.Features of this Motherboard
This motherboard is designed for the new generation of CPUs. It supports the Intel SLOT1
structure (Pentium

II/III processor), up to 1GB of memory, super I/O, and Green PC
functions. The motherboard provides high performance for server systems and meets the
requirements for future multimedia desktop systems.
The CX6 uses the new generation Intel
®
820 chipset ( Camino ) for more efficiency and high
integration of the system. What are the main features of the Intel
®
Camino chipset? Its
structure is shown in Figure 1-2.
➠
133 MHz System Bus
!
The Intel
®
820 platform supports the new 133 MHz system bus
" Up to 33% increased peak bandwidth over the Intel ® 440BX platform.
➠
AGP 4x Graphics
! Up to 1GB/Sec transfer rate
" Twice the peak bandwidth of AGP 2x of the 440BX AGPset
! Broad industry support for AGP 4x from all leading graphics IHVs
" NVIDIA, 3Dfx, S3, ATI, Intel, Matrox, etc.
➠
RDRAM Memory
! Provides memory bandwidth to keep up with ever increasing application demands
" Faster processors, graphics, and I/O
! RDRAM delivers up to 3x the effective bandwidth of PC100 SDRAM
" 1.6 GByte/sec for PC800 RDRAM
! RDRAM provides the required headroom for further application improvement
" Constant Computing
" More realistic environments
" Platform longevity and stability
The Intel
®
820 chipset is a combination of three chips: the FW82820, FW82801 and
FW82802. The FW82820 is called MCH chip (

MCH (Memory Controller Hub)
The MCH provides the host interface, DRAM interface, I/O interface, and AGP interface in
a Camino platform. Camino MCH is optimized for the Katmai or Coppermine processor. It
supports a single channel of direct Rambus memory technology. Its AGP interface is fully
compliant with AGP 2.0 specification. Communication to ICH is over a private interface or
the hub interface (link). The Camino MCH contains the following functionality:
