Memory
Systems Using Single or Dual Channel Memory
The d200 series computers come with Double Data Rate-Synchronous Dynamic Random Access
Memory (DDR-SDRAM) Dual Inline Memory Modules (DIMMs).
The memory sockets on the system board can be populated with industry-standard DIMMs and
come from the factory with at least one preinstalled memory module per computer. To achieve
the maximum memory support, you may be required to replace the preinstalled DIMM with a
higher capacity DIMM.
✎
Only select models ship with dual channel memory capability.
The DIMMs used must be industry-standard 184-pin, unbuffered PC2100 266 MHz-, PC2700
333 MHz-, or PC3200 400 MHz-compliant (select models), 2.5 volt DDR-SDRAM DIMMs.
The following features are required:
■
CAS latency 2, 2.5, or 3 (CL = 2, CL = 2.5, CL=3)
■
Modules must contain the mandatory Joint Electronic Device Engineering Council (JEDEC)
Serial Presence Detect (SPD) information.
■
128Mbit, 256 Mbit, and 512Mbit non-ECC memory technologies
■
Single and double-sided DIMMs may be used
DIMMs constructed with x8 and x16 DDR devices and x4 SDRAM are not supported.
✎
The system will not start using unsupported DIMMs.
