Main Memory - Intel D815EGEW Product Manual

Main Memory

✏
NOTE
To be fully compliant with all applicable Intel
be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your
memory modules do not support SPD, you will see a notification to this effect on the screen at
power up. The BIOS will attempt to configure the memory controller for normal operation at
100 MHz.
✏
NOTE
Because the main system memory is also used as video memory, the board requires a 100 MHz
SDRAM DIMM even though the host bus frequency is 66 MHz. It is highly recommended that an
SPD DIMM be used, since this allows the BIOS to read the SPD data and program the chipset to
accurately configure memory settings for optimum performance. If non-SPD memory is installed,
the BIOS will attempt to correctly configure the memory settings, but performance and reliability
may be impacted.
The board supports memory as defined below:
•
Two 3.3 V, 168-pin SDRAM Dual Inline Memory Modules (DIMMs) with gold-plated
contacts
•
Unbuffered single or double-sided DIMM configurations
•
100 MHz PC100 SDRAM (all FSB frequencies)
•
133 MHz PC133 SDRAM (only supported with 133 MHz system bus frequency)
•
Minimum system memory: 64 MB
•
Maximum system memory: 512 MB
✏
NOTE
The BIOS cannot determine DIMM size or type when not initialized. If more than 512 MB system
memory is installed, the BIOS displays a message at boot indicating memory above 512 MB has
not been initialized. The message indicates that additional information is available in Setup. The
first time the BIOS detects this condition, a pause follows the message with the option to enter
Setup or to press <ESC> and continue to boot. The message continues to be displayed at boot
time as long as the condition exists, however, the BIOS will not pause on subsequent detection.
Setup displays the installed memory configuration and shows memory above 512 MB as "not
initialized."
•
Basic non-SPD at 100 MHz
•
Suspend to RAM support
•
Mixed speed DIMM configuration will default to the slowest speed DIMM installed.
