Capacity and fit

This 16 GB kit contains four 4 GB registered ECC DIMMs built for the HP xw8200 workstation series. Each module runs at DDR2 400 (PC2-3200) with CL3 timing at 1.8 V. The dual-rank 2Rx4 design matches the chipset limit of eight ranks. BIOS must be current for the full 16 GB to be recognised.

Sustained behaviour

Registered buffering and ECC keep data integrity stable during long server workloads. The modules operate within standard DDR2 voltage and timing, so thermal load remains predictable across extended sessions. Rank population rules require the first DIMM singly, then pairs, which maintains consistent electrical loading.

Upgrade context

The kit replaces smaller or non-ECC configurations that cannot reach the 16 GB ceiling or lack error correction. It is not suited for systems that accept only single-rank modules or non-registered memory. Builders needing higher density per slot or a newer DDR generation must choose a different platform.

Questions sur cet article

How much power does this DDR2 400 memory kit draw at its rated 1.8V when the workstation runs continuously?

Each module operates at the standard DDR2 voltage of 1.8V; total power draw depends on the system's memory controller and workload.

What must the HP xw8200 workstation already have installed so these four 240-pin Registered ECC DIMMs can function?

The board must support Registered ECC DDR2 memory, provide six 240-pin slots, and run a BIOS version that recognises 16 GB across four dual-rank modules.

Can I keep the original 4 GB of slower DDR2 memory in the other two slots alongside this 16 GB kit?

The chipset allows a maximum of eight ranks; this kit uses eight ranks itself, so no additional DIMMs can be added without exceeding the rank limit.
