3.3 System Memory support
The 986LCD-M boards have two onboard DDR2 DIMM sockets and support the following memory features:
• 1.8V (only) 240-pin DDR2 SDRAM DIMMs with gold-plated contacts
• Supports Single- / Dual channel DDR2 SDRAM
• Supports 256 Mbit, 512 Mbit and 1 Gbit technologies for x8 ans x16 width devices
256MB, 512MB and 1GB Single Rank Modules supported
512MB, 1GB and 2GB Dual Rank Modules supported
• Maximum of 3 Gbytes (2GB + 1GB) based on Samsung PC5300U-M378T5663AZ3-CE6 +
PC5300U_M378T2953CZ3-CE6).
• Supports 400 MHz (PC3200) , 533 MHz (PC4200), and 667 MHz (PC5400) DDR2 devices
• 64-bit data interface (ECC not supported)
The installed DDR2 SDRAM should support the Serial Presence Detect (SPD) data structure. This allows the
BIOS to read and configure the memory controller for optimal performance. If non-SPD memory is used, the
BIOS will attempt to configure the memory settings, but performance and reliability may be impacted.
Important: If only one module is used then use Slot 0.
