Mini-ITX Motherboard Features

Processor

CAUTION

Failure to use an appropriate power supply and/or not connec ting the 12 V (2 x 2)
power connector to the Board may result in damage to the board, or the
system may not function properly.

The Mini-ITX Motherbaord 2807638 includes an Intel Celeron processor. The processor is
soldered to the Board and is not customer upgradeable.

Main Memory

NOTE

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.

The Board has one 240-pin Double Data Rate 2 (DDR2) SDRAM Dual Inline
Memory Module (DIMM) connector with gold-plated contacts. It supports:

• 533/400 MHz unbuffered, non-registered DDR2 DIMMs

• Serial Presence Detect (SPD) memory only

• Non-ECC memory

• Up to 1 GB of system memory utilizing 512 Mb or 1 Gb technology
