System-Specific Kit for Dell 670

This 4 GB kit contains two 2 GB registered DDR2 modules built to match the Dell Precision Workstation 670 specification. It is aimed at administrators extending the life of that workstation platform. Buyers needing unbuffered desktop memory or a different pin count cannot use these sticks.

Thermals and Power Profile

The modules run at the standard 1.8 V for DDR2 400 and carry no heat spreader, relying on chassis airflow for cooling. Registered buffering adds a small electrical load compared with unbuffered parts, but power draw remains within the workstation's original memory budget. No active cooling or special voltage rails are required.

Bundled Items and Firmware Impact

The package supplies only the two DIMMs; no software, drivers or configuration utilities are included. Installation simply adds registered dual-rank capacity to the supported slots, allowing the system firmware to initialise the extra ranks up to the chipset's eight-rank limit. No BIOS update or operating-system change is triggered by the memory itself.

Questions about this item

How do I install the 240-Pin DDR2 400 modules in a Dell Precision Workstation 670, and what step is often missed?

Insert the first registered DIMM into the primary slot; additional modules must be added in matched pairs to satisfy the dual-rank requirement.

What maintenance or replacement will the CM256723200ECCREG2R4 kit need over time?

No routine maintenance is required; if a module fails, replace it with an identical 2Rx4 registered DDR2 400 stick to keep rank balance.

What limit appears first when the Dell Precision Workstation 670 runs sustained workloads with this memory?

The chipset caps total ranks at eight, so populating beyond four dual-rank DIMMs will prevent further memory expansion.
