Motherboard Description
1.3 Memory
The motherboard has two DIMM sockets. Using the serial presence detect (SPD) data structure,
2
programmed into an EPROM on the DIMM, the BIOS can determine the SDRAM?s size and
speed. Minimum memory size is 16 MB; maximum memory size is 256 MB. Memory can be
installed in one or both sockets. Memory size can vary between sockets.
The motherboard supports the following memory features:
? 168-pin SPD or non-SPD DIMMs with gold-plated contacts
? 66 MHz or 100 MHz unbuffered SDRAM
? 64-bit (non-ECC) memory
? 3.3 V memory only
? Single- or double-sided DIMMs in the sizes listed in Table 2
Table 2.Supported Memory Sizes and
Configurations
DIMM SizeConfiguration
16 MB2 Mbit x 64
32 MB4 Mbit x 64
64 MB8 Mbit x 64
128 MB16 Mbit x 64
All memory components and DIMMs used with this motherboard must comply with the following
PC SDRAM specifications:
? PC SDRAM Specification (memory component specific)
? PC Unbuffered SDRAM Specifications
? PC Serial Presence Detect Specification

Obtaining copies of PC SDRAM specificationshttp:// www.intel.com/design/pcisets/memory
/NOTE
The board is compatible with both 66 MHz and 100 MHz DIMMs, but installing faster speed
memory will not increase system performance, because of the 66 MHz host bus frequency.
CAUTION
?
To be fully compliant with all applicable Intel SDRAM specifications, use DIMMs that support
the 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, non-SPD DIMMs might not function at the determined frequency.
Refer to the PC Serial Presence Detect Specification for more information.
