  • 8 V operation matches original server voltage requirements

Server-Ready 16GB DDR2 Kit

This 16GB kit contains four 4GB DDR2-667 registered ECC DIMMs built for the HP ProLiant DL185 G5 server. Each module runs at 1.8V with CL5 timing and a 2Rx4 organisation. The registered buffer and error-correcting code suit multi-socket workloads that demand data integrity.

Sustained Load Behaviour

Registered signalling reduces electrical loading on the memory bus, allowing all eight sockets to be populated without timing degradation. ECC corrects single-bit errors on the fly, preventing silent data corruption during long compute runs. Dual-rank 2Rx4 chips enable four-way bank interleaving when four DIMMs are installed per processor node.

Upgrade Context

The kit expands a DL185 G5 toward its 64GB maximum across eight slots. Install kits in decreasing capacity order, placing the largest modules in the banks furthest from each CPU. Mixing single and dual-rank DIMMs on the same node disables bank interleaving, so match ranks within each processor. Only Opteron models 2378, 2382 or 2384 support DDR2-800; otherwise the system clocks to 667MHz.

Questions about this item

How much power does this 1.8 V DDR2 kit draw in a ProLiant DL185 G5 running 24/7?

Each module operates at the standard 1.8 V DDR2 voltage; total power scales with the four 4 GB sticks installed, so the server's own power budget and cooling determine actual draw under load.

What server configuration is required before adding these 240-pin registered ECC DIMMs?

The kit is validated for HP/Compaq ProLiant DL185 G5 systems with Opteron third-generation processors; eight sockets are available across two banks per CPU, and kits must be installed in decreasing capacity order.

Will these 667 MHz dual-rank modules keep bank interleaving if I mix them with existing single-rank DIMMs?

Mixing single and dual ranked DIMMs on the same processor node disables bank interleaving, so all four slots per node should use matching 2Rx4 modules for 4-way interleaving.
