Dell PowerEdge 1800 memory kit

This kit supplies two 4 GB registered ECC DIMMs for a total of 8 GB. It is built for the Dell PowerEdge 1800 server and runs at DDR2 400 MHz with CL3 timing. The modules use 240-pin DDR2 SDRAM at 1.8 V and carry a 2Rx4 dual-rank organisation.

Compatibility checklist

Verify that your PowerEdge 1800 currently uses registered ECC DDR2 memory and that the motherboard accepts dual-rank 2Rx4 modules. The chipset supports a maximum of eight ranks, so confirm the existing rank count before adding this pair. The first DIMM slot can be populated alone, but any further memory must be installed in matched pairs.

Build integration

The two sticks populate adjacent slots to maintain the required paired configuration. Registered buffering reduces electrical load on the memory controller, allowing the full rank budget to be used. No heat spreader is fitted, so airflow through the server chassis provides the necessary cooling.

Questions sur cet article

Does the kit include only the two 4GB DIMMs or are extra brackets or cables required?

The package contains two 240-pin DDR2 registered ECC DIMMs and nothing else; no brackets, cables or additional parts are needed for installation.

Should I choose the 2Rx4 dual-rank version or look for a single-rank alternative for my Dell PowerEdge 1800?

This kit uses 2Rx4 dual-rank modules; the system board supports up to eight ranks total, so two dual-rank DIMMs consume four ranks and leave room for further paired upgrades.

What does the PC2-3200 400 MHz rating mean for actual throughput in the server?

Each module transfers data at the standard DDR2-400 rate with CL3 timing at 1.8 V, delivering the bandwidth the PowerEdge 1800 memory controller expects for registered ECC operation.
