HPE 16GB DDR3-1600 ECC Registered module

This 16GB DDR3 SDRAM module runs at 1600 MHz with CL11 latency. It uses a 240-pin form factor and includes ECC error checking with registered signal processing. The part is designed for server platforms that require registered memory. Buyers needing unbuffered desktop memory or a different DDR generation should select another product.

Thermals noise and power draw

DDR3 memory operates at a standard voltage that keeps heat output low inside a server chassis. Registered buffering adds minimal electrical load while improving signal integrity across multiple modules. No active cooling is required beyond normal system airflow. The module produces no audible noise during operation.

What the ECC and registered features change

ECC detects and corrects single-bit errors to protect data integrity in critical workloads. Registered signal processing reduces electrical load on the memory controller, allowing larger memory configurations. Together these features enable stable operation in multi-module server environments. Systems without ECC or registered support cannot use this module.

Questions about this item

How do I install the 240-pin DDR3 module and what step is often missed?

Align the notch on the 240-pin DDR3 module with the slot key, press firmly until both side clips click shut, then verify the server BIOS reports the full 16 GB at 1600 MHz.

What maintenance or replacement will this 16 GB registered ECC module need over time?

No routine maintenance is required; if a correctable ECC error count rises or the module fails POST, replace the single 16 GB stick with an identical DDR3-1600 CL11 registered part.

What limit appears first when this CL11 registered memory runs sustained workloads?

The CAS latency of CL11 at 1600 MHz sets the timing floor; sustained throughput cannot exceed the PC3-12800 bandwidth ceiling of the DDR3 interface.
