System-Specific DDR2 Upgrade

This 8GB kit contains two 4GB registered ECC DIMMs built for the HP ProLiant DL580 G3 server. Each module runs at DDR2 400 (PC2 3200) with CL3 timing at 1.8V and uses a dual-rank 2Rx4 organisation. The 240-pin form factor matches the memory boards designed for this platform.

Thermals and Power Draw

Registered DDR2 modules operate at the standard 1.8V without a heat spreader, relying on server chassis airflow for cooling. ECC and register logic add minimal overhead, so power draw stays within the platform's original memory budget. Acoustic impact is negligible because the server's existing fans handle the thermal load.

Build Integration

The kit plugs into the 240-pin sockets on optional memory boards (364639-B21), each board providing four sockets across two banks. Four boards yield 16 sockets total and support up to 64GB when fully populated. Buyers needing single-rank modules or capacities beyond 64GB must look elsewhere.

Preguntas sobre este artículo

How do I install the 240-pin DDR2 ECC registered DIMMs in the ProLiant DL580 G3, and what step is often missed?

Install modules in matched pairs per bank on each memory board; the step often missed is seating both modules of a pair before locking the ejector levers.

What maintenance or replacement will the 2Rx4 DDR2 400 MHz registered kit need over time?

No routine maintenance is required; replacement is only needed if a module fails or if capacity must exceed the 64 GB maximum supported across four memory boards.

What limit appears first when the ProLiant DL580 G3 runs sustained workloads with this 1.8 V DDR2 memory?

The 64 GB total capacity ceiling across the four memory boards is the first hard limit reached under sustained use.
