Appendix F Memory; Ddr2-Sdram Dimms - HP xw3400 - Workstation Technical Reference Manual

Memory
F
The workstation comes with double data rate 2 synchronous dynamic random access memory (DDR2-
SDRAM) dual inline memory modules (DIMMs).
CAUTION:

DDR2-SDRAM DIMMs

The memory sockets on the system board can be populated with up to four industry-standard DIMMs.
These memory sockets are populated with at least one preinstalled DIMM. To achieve the maximum
memory support, you can populate the system board with up to 4 GB of memory configured in a high-
performing dual channel mode.
For proper system operation, the DDR2-SDRAM DIMMs must be:
industry-standard 240-pin
●
unbuffered PC2-5300 667 MHz-compliant
●
1.8 volt DDR2-SDRAM DIMMs
●
The DDR2-SDRAM DIMMs must also:
support CAS latency 4 and 5 for DDR2/667 MHz
●
contain the mandatory JEDEC SPD information
●
In addition, the workstation supports:
256Mbit, 512Mbit, and 1Gbit 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
NOTE:
The system will not start if you install unsupported DIMMs.
ENWW
DDR and DDR2 memory modules are not interchangeable.
