16GB DDR3-1333 ECC Registered Kit

This 16GB kit contains two 8GB DDR3-1333 registered ECC DIMMs built for the HP Z800 workstation. Each module runs at 1.5V with CL9 9-9-9 timing and uses a 2Rx4 organisation. The 240-pin form factor fits the Z800’s twelve memory sockets directly.

Suits Z800 owners adding ECC registered capacity

Buyers needing unbuffered ECC or non-ECC UDIMMs cannot use this kit because the Z800 requires registered modules for capacities above 48GB. Systems limited to 1066MHz or 800MHz by processor choice will still accept the DIMMs, but they will clock down automatically. Workstations other than the Z800 are not validated for this part.

Registered ECC stabilises multi-DIMM loads

Under sustained workloads the registered buffer reduces electrical loading on the memory controller, allowing all twelve sockets to be populated without signal degradation. The modules automatically drop to 1066MHz or 800MHz when the installed processor or population rules demand it, preventing instability during long compute sessions.

Domande su questo articolo

Do I need a Xeon X5550 or higher processor for the 1333 MHz speed to be active?

Yes, the 1333 MHz speed requires a Xeon X5550 or higher processor; with lower models the modules will clock down to 1066 MHz or 800 MHz depending on the CPU and how many DIMMs are installed.

Can I keep my existing 800 MHz DDR3 modules and add this 1333 MHz kit?

The kit will automatically clock down to match the slowest installed modules, so it will run at 800 MHz alongside older DDR3 memory in the Z800.

How can I confirm the kit is running in registered ECC mode after installation?

Check the BIOS memory configuration or use a system information tool; it should report 16 GB of DDR3-1333 registered ECC memory operating at 1.5 V with CL9 timings.
