Compatible with Dell PowerEdge 1800

This registered ECC DIMM kit is built for the Dell PowerEdge 1800 server platform. It provides 4 GB total capacity across two 2 GB modules running at DDR2 400 (PC2 3200). The dual-rank design suits server workloads that require registered memory with error correction.

Installation notes

Modules use the standard 240-pin DDR2 form factor and operate at 1.8 V. The system requires memory to be populated in pairs after the first DIMM, and the chipset supports a maximum of eight ranks. Mixing registered and unbuffered modules will prevent the server from booting.

Before ordering

Verify that the server currently uses registered ECC DDR2 memory and has free 240-pin slots available. Confirm the existing configuration does not already exceed the eight-rank limit. This kit is not suitable for desktop motherboards or systems that require unbuffered non-ECC memory.
