Capacity 16GB (2 x 8GB)

  • 16 GB dual-channel kit adds capacity for heavier server workloads
  • DDR3 1866 MHz speed moves data faster through registered channels
  • ECC registered design detects and corrects memory errors automatically
  • CL13 latency at 1.5 V balances responsiveness with standard voltage
  • 240-pin 1Rx4 modules fit compatible DDR3 server and workstation slots

16GB Dual-Channel Server Kit

This 16GB kit contains two 8GB DDR3 1866 ECC RDIMM modules built for registered server and workstation platforms. It operates at 1.5V standard voltage with CL13 latency and single-rank x4 organisation. The modules use major-brand chips and are tested for dependable operation in compatible systems.

Capacity and Headroom

The 16GB total capacity handles typical virtualisation workloads, database caching and multi-user application serving with comfortable headroom. Memory-intensive tasks such as large in-memory analytics or dense container deployments will exhaust the available space and require a higher-capacity configuration or additional DIMM slots.

Build Integration

These 240-pin registered DIMMs require a motherboard that supports DDR3 ECC RDIMM memory and cannot be used in desktop or laptop computers. The dual-channel kit populates two slots for optimal bandwidth and leaves remaining slots free for future expansion. Verify your system manual for correct channel population rules before installation.

Questions about this item

Will these 1866 MHz registered ECC DIMMs run reliably at the speed of the slower DDR3 modules I already have installed?

The kit is rated for DDR3 1866 (PC3-14900) at CL13 and 1.5 V; when mixed with slower DDR3 RDIMMs the system will clock all modules down to the lowest common speed and the loosest timings present.

How can I confirm the 1Rx4 ECC registered modules are operating correctly after installation?

Check the BIOS or UEFI memory information screen: it should report 16 GB total, DDR3 1866, registered ECC, single-rank x4 organisation, and 1.5 V operation.

Does the box contain only the two 8 GB RDIMMs or are any brackets, cables or tools included?

The package includes the two 240-pin DDR3 1866 MHz ECC registered DIMMs (2 × 8 GB) and no additional brackets, cables or installation tools.
