8 GB DDR3 1866 ECC RDIMM

This 8 GB DDR3 1866 MHz registered ECC module is built for HP server and workstation platforms that require PC3-14900 memory. It uses a 240-pin DIMM form factor with a 2Rx4 organisation and operates at the standard 1.5 V. The module carries CL13 latency and major-brand chips for dependable operation in multi-socket systems.

Suited for HP server upgrades not for non-ECC boards

This module suits administrators expanding HP ProLiant or compatible workstations that specifically call for registered ECC DDR3 at 1866 MHz. It will not work in desktop boards that accept only unbuffered non-ECC memory, nor in systems limited to lower DDR3 speeds or different voltage requirements. Verify your platform documentation before purchase.

Registered ECC DDR3 at 1866 MHz

The single specification that decides fitment is the registered ECC DDR3 1866 MHz rating with 2Rx4 organisation. Only platforms that explicitly support this combination of buffering, error correction, speed and rank configuration will recognise and run the module correctly.

Questions about this item

Will the registered DIMM design require any special motherboard slots or maintenance compared to standard memory?

The module uses a standard 240-pin DDR3 DIMM form factor, so it fits regular DDR3 registered DIMM slots and needs no extra maintenance beyond normal dust control.

What is the first limit reached when this CL13 1866 MHz module runs at full load for long periods?

The DDR3 1866 MHz speed rating and CL13 latency set the performance ceiling; sustained throughput cannot exceed the rated PC3-14900 bandwidth.

How much heat and power does the 1.5 V 8 GB registered module produce during all-day server operation?

At the standard 1.5 V DDR3 voltage the module draws typical DDR3 power and generates modest heat, well within normal server cooling capacity.
