Chipset Overview (865G:P4SPA+, 865PE:P4SPE)
Intel’s Sprindale (865G, 865PE) chipset is comprised of two primary compo-
nents: the Graphics Memory Controller Hub (GMCH) and the I/O Controller
Hub (ICH5). The Sprindale (865G, 865PE) provides the performance and
feature-set required for high-end dual/single-processor desktop and work-
station systems.
Graphics Memory Controller Hub (GMCH)
The GMCH provides the host (CPU) interface, DDR (Memory) interface,
AGP interface, ICH5(Hub), CSA interface and 8xAGP interface for the
Sprindale (865G, 865PE) chipset. The CPU interface supports the Pentium 4
Processor subset of the Extended Mode of the Scalable Bus Protocol. The
GMCH memory interface supports dual channel DDR, and the 1.5V AGP slot
which supports 8X/4X data transfers and AGP Fast Writes. The Integrated
Graphics Controller provides 3D, 2D high performance graphics solution.
Host Interface
and System Memory Interface
The Springdale GMCH can utilize a single PGA 478-pin processor. It sup-
ports a FSB frequency of 800/533/400 MHz(100 MHz, 133 MHz, and 200
MHz CLK respectively). It supports 32-bit host addressing, decoding up to
4GB of the CPU's memory address space. The Springdale GMCH integrates
a system memory DDR Controller which supports dual DDR data channels,
with a bandwidth up to 3.2GB/s(DDR 400) for single-channel mode and
6.4GB/s(DDR 400) for dual-channel mode.
Intel ICH5 System Features
The I/O Controller Hub provides the I/O subsystem with access to the rest
of the system. It supports dual channel Ultra ATA/100 Bus Master IDE
Controller, two Serial ATA (SATA) Host Controllers, SMBus 2.0 Controller,
LPC/Flash BIOS Interface, PCI 2.3 Interface, and Integrated System Manage-
ment Controller.
Graphics Features/Display (865G:
for
P4SPA+ only
)
The Springdale GMCH provides an integrated graphics accelerator deliver-
ing 3D, 2D and video capabilities. It also provides interfaces to a progres-
sive scan analog monitor and two DVO devices. It
is compliant with DVI
specification and has a high-speed interface to a digital display.
