2 Motherboard Description

2.1

Processor

The GL815E motherboard supports Intel Celeron and Pentium III processors in a PGA370 package
(FC-PGA). The table below lists the supported processors. An on-board voltage regulator generates
the voltage for the CPU. Both the processor voltage and the operating frequency are automatically
adjusted by the motherboard to suit the installed processor.
Processor Type Processor Speed
Intel Celeron 566 MHz
Intel Celeron 733 MHz
Intel Celeron 850 MHz
Intel Pentium III 600 MHz
Intel Pentium III 700 MHz
Intel Pentium III 733 MHz
Intel Pentium III 850 MHz
Intel Pentium III 866 MHz
Intel Pentium III 1.0 GHz
2.2

System Memory

The GL815E motherboard has two DIMM sockets to accept PC100 or PC133 modules. The product
does not accept PC66 modules. The sockets may be populated in any order and each can accept
either single or double-sided modules. The minimum total memory size is 16MB and the maximum
is 512MB. The BIOS automatically configures the motherboard for the correct size, speed and type.
For best performance, use PC133 modules with a 133MHz bus processor. When using a 100MHz
bus processor, the module will always operate at 100MHz regardless of type. See the Manuals,
Drivers & BIOS section on the RadiSys web site at
that have been tested with this product.
When using the on-board video controller, the frame buffer is held within system memory
and thus less memory is available to the operating system.
Each memory module should meet the following requirements
•
Compliance with the Intel PC100 or PC133 specification
•
Inclusion of a serial presence detect (SPD) ROM
•
The module type is 3.3V 168-pin unbuffered synchronous DRAM (SDRAM)
•
Based on 16Mb, 64Mb, 128Mb or 256Mb devices
•
Capacity of between 16MB and 512MB
•
64 bits wide. ECC or parity is not supported
