Target System Compatibility

This memory kit is designed specifically for the Dell PowerEdge 2800 server. It provides 8GB total capacity across two 4GB modules using 240-Pin DDR2 SDRAM technology. The modules operate at 400 MHz with a PC2-3200 rating and require a 1.8V supply voltage.

Registered ECC Configuration

Suited for administrators maintaining a Dell PowerEdge 2800 requiring registered ECC memory with dual-rank architecture. Builders needing unbuffered, non-ECC, or single-rank modules for other platforms cannot use this kit.

DDR2 400 Speed Rating

The decisive specification is the DDR2 400 (PC2-3200) speed grade with CL3 3-3-3 timing. Only systems qualified for this exact DDR2 frequency and registered signal loading will accept these modules.

Questions about this item

Will the 240-pin DDR2 modules fit the Dell PowerEdge 2800 memory slots?

Yes, these 240-pin DDR2 registered DIMMs are built for the PowerEdge 2800 and install directly into its DDR2 memory slots.

What is the correct population order when installing the two 4GB sticks?

The first DIMM can be populated alone; any additional memory must be added in pairs, so install the second stick in the matching paired slot.

Does the registered ECC design need any firmware updates or battery-backed maintenance over time?

No firmware or battery maintenance is required; the modules run at 1.8V with standard registered ECC operation for the life of the system.
