Product Description

1.5 System Memory

CAUTION

To be fully compliant with all applicable Intel®SDRAM memory specifications, the board should 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; however, DIMMs may not function at the determined frequency.

CAUTION

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 has one DIMM socket. The minimum memory size is 32 MB and the maximum memory size is 256 MB. The BIOS automatically detects memory type, size, and frequency.

The board supports the following memory features:

∙3.3 V, 168-pin DIMM with gold-plated contacts

∙100 MHz SDRAM

∙Serial Presence Detect (SPD) or non-SPD memory (BIOS recovery requires an SPD DIMM)

∙Non-ECC (64-bit) memory

∙Unbuffered single- or double-sided DIMM

The board is designed to support the DIMM configurations listed in Table 4 below.
