Adding System Memory

DIMMs

DDR DIMMs

2–4
The memory sockets on models equipped with the Intel Pentium 4
processor must be populated with double data rate SDRAM
(DDR-SDRAM) DIMMs. To achieve the maximum memory support,
you can populate the system board with up to 2GB of memory
configured in a high-performing dual channel mode.
For proper system operation, the DIMMs must be industry-standard
184-pin, unbuffered PC 2100 266 Mhz-, PC 2700 333 Mhz-, or
PC3200 400 Mhz-compliant 2.5 volt DDR-SDRAM DIMMs. The
DDR-SDRAM DIMMs must also:
■
support CAS Latency 2 or 2.5 (CL = 2 or CL = 2.5)
■
contain the mandatory Joint Electronic Device Engineering
Council (JEDEC) Serial Presence Detect (SPD) information
In addition, the system supports:
■
128Mbit, 256Mbit, and 512Mbit non-ECC memory technologies
■
single-sided and double-sided DIMMs
■
DIMMs constructed with x8 and x16 DDR devices; DIMMs
constructed with x4 SDRAM are not supported.
The following processor bus frequencies are required for the system
to run at the supported memory frequencies.
Memory Frequency
266 MHz
333 MHz
