System Memory
The board has two DIMM sockets and support the following memory features:
•
1.8 V DDR2 SDRAM DIMMs with gold plated contacts, with the option to raise the
voltage to support higher performance DDR2 SDRAM DIMMs
•
Dual channel interleaved mode support
•
Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMs with x16 organization are not supported.
•
4 GB maximum total system memory using DDR2 800 MHz or DDR2 667 MHz
DIMMs; refer to Section 2.1.1 on page 45 for information on the total amount of
addressable memory.
•
Minimum recommended total system memory: 512 MB
•
Non-ECC DIMMs
•
Serial Presence Detect
•
DDR2 800 MHz or DDR2 667 MHz SDRAM DIMMs
•
DDR2 667 MHz DIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP)
•
DDR2 800 MHz DIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP)
NOTE
To be fully compliant with all applicable DDR SDRAM memory specifications, the board
should be populated with DIMMs that support the Serial Presence Detect (SPD) data
structure. 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 or the DIMMs may not function under the
determined frequency.
