System-specific DDR2 kit

This 16 GB kit contains four 4 GB registered ECC DIMMs built for the Dell Precision Workstation 670. The modules run at 400 MHz with CL3 timing and 1.8 V operation. Dual-rank organisation suits server workloads that require error correction.

Installation constraints

The workstation chipset supports a maximum of eight ranks. Dual-rank modules are only supported in the first four sockets; populating sockets five or six with dual-rank DIMMs disables them. A 64-bit operating system is needed to address more than 4 GB and Dell requires an extra cooling fan when total memory exceeds 4 GB.

Sustained-load behaviour

Registered buffering and ECC maintain data integrity during continuous server operation. The dual-rank layout fills the supported rank budget quickly, so further expansion is limited by the chipset rather than thermals. Chipkill (SDDC) support is present on these 4 GB modules.

商品問答

Does the kit contain four separate modules or a single 16 GB stick?

The kit ships as four individual 4 GB DDR2 400 modules, giving 16 GB total capacity.

Should I pick the dual-rank 4 GB modules or look for single-rank alternatives?

Dual-rank 4 GB modules are supported only in sockets DIMM_1 through DIMM_4; sockets DIMM_5 and DIMM_6 require single-rank modules.

Will the system show the full 16 GB once all four modules are installed?

With a 32-bit OS the system may report only 3.5 GB; a 64-bit OS and the extra cooling fan Dell requires are needed to address the full 16 GB.
