System Memory support
The KTUS15 boards have one 200-pin DDR2 Small Outline Dual Inline Memory Module (SO-DIMM) socket.
The socket can be populated with up to 2GB of unbuffered DDR2 SO-DIMM modules.
Memory speeds up to 533MT/s (PC-4200) are supported.
•
Supports 1.8-V DDR2 SDRAM with gold-plated contacts
•
SDRAM Organisation of x16 supported only, up to 2 ranks, 8 loads only
•
Supports 400 MT/s and 533 MT/s data rates
•
Single 64-bit wide single-channel
•
Support system memory from 512MB and up to 2GB
•
Device density support for 512Mb and 1024Mb devices
•
ECC not supported
•
Serial Presence Detect required
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.
Memory Operating Frequencies
The KTUS15/mITX maintains a fixed relationship between DRAM to FSB clock frequency. The FSB
frequency can be 400MHz or 533MHz, resulting in support of the following clock frequencies and data rates
for the DRAM.
