Server Memory Kit for DDR4 Platforms

This 16 GB kit contains two 8 GB registered ECC RDIMMs built for DDR4 servers and workstations. It runs at 2666 MT/s with CL19 latency at 1.2 V. The modules use 1Rx4 organisation and major-brand DRAM chips.

Upgrade from Non-ECC or Lower-Capacity DIMMs

The jump is worthwhile when your workload demands error correction and registered signalling for data integrity. It replaces unbuffered or non-ECC memory that cannot meet server-class stability requirements.

Straightforward 288-Pin Installation

Align the notch with the motherboard key and press firmly until the latches click. The most common issue is mixing registered and unbuffered DIMMs on the same board, which prevents the system from posting.

Questions about this item

Will the 288-pin DDR4 2666 RDIMM kit fit my server's DIMM slots?

The kit uses the standard 288-pin DDR4 form factor and runs at 1.2 V. It fits any server or workstation slot designed for DDR4 registered memory.

What is the correct way to install the 2x8 GB registered modules, and what step is often missed?

Power down the system, open the chassis, align each module's notch with the slot key, and press firmly until both retention clips lock. The step often missed is confirming the motherboard requires registered ECC memory before purchase.

How long can the 1Rx4 ECC registered modules run before they need replacement?

The modules are built with major-brand DRAM chips and tested for reliability. No scheduled replacement interval exists; they remain in service until a memory error appears or a capacity upgrade is required.
