Overview
The Intel
815 chipset family is a high-flexibility chipset designed to extend from the basic
graphics/multimedia PC platform up to the mainstream performance desktop platform. The chipset
consists of a 82815 Graphics and Memory Controller Hub (GMCH) and an I/O Controller Hub for the
I/O subsystem. The GMCH integrates a system memory SDRAM controller that supports a
64-bit 100/133 MHz SDRAM array.
The 82815 GMCH integrates a Display Cache SDRAM controller that supports a 32-bit 133 MHz
SDRAM array for enhanced integrated 2D and 3D graphics performance. Multiplexed with the display
cache interface is an AGP controller interface to enable graphics configuration and upgrade flexibility
with the Intel
815 chipset family. The AGP interface and the internal graphics device are mutually
exclusive. When the AGP port is populated with an AGP graphics card, the integrated graphics is
disabled; thus, the display cache interface is not needed.
There are two chipsets in the Intel
815 chipset family:
Intel
815 chipset: This chipset contains the 82815 GMCH and 82801AA ICH.
Intel
815E chipset. This chipset contains the 82815 GMCH and 82801BA ICH2.
Note:
The only component difference between the Intel
815 chipset and the Intel
815E chipset is the I/O
Controller Hub.
This datasheet provides an overview of the 815 chipset family (see Section 1.2). The remainder of the
document describes the Intel
82815 Graphics Memory Controller Hub (GMCH).
The Intel
815 chipset family may contain design defects or errors known as errata which may cause the product to deviate from
published specifications. Current characterized errata are available on request.
