Rank 4Rx4

  • 64 GB total capacity from two 32 GB modules
  • DDR4 2133 speed rated at PC4 17000
  • ECC registered design detects and corrects memory errors
  • 288 pin DDR4 form factor fits standard server slots
  • 4Rx4 rank organisation optimises density for server workloads

Server memory kit for enterprise upgrades

This 64 GB kit contains two 32 GB DDR4 modules built for registered ECC server platforms. The 288-pin DIMMs target administrators who need dependable capacity expansion without changing existing infrastructure. Each stick is tested for compatibility across a wide range of qualified systems.

64 GB capacity with quad-rank density

The paired modules deliver 64 GB total using 4Rx4 organisation, giving dense memory footprints for virtualisation hosts and database nodes. Headroom scales with the number of populated slots; once the motherboard's registered DIMM limit is reached, further expansion requires higher-density parts or a platform change.

DDR4 2133 registered ECC interface

The memory runs at DDR4 2133 (PC4 17000) speeds under the registered ECC protocol, which adds a clock cycle for signal buffering and enables single-bit error correction. Bandwidth and latency are bounded by the 2133 MT/s data rate, so workloads demanding higher throughput will hit the interface ceiling before the capacity limit.

Questions about this item

Will this 2133 MHz registered ECC kit run alongside existing DDR4 2133 modules in my server?

The kit is DDR4 2133 (PC4 17000) registered ECC with a 4Rx4 organisation. Mixing ranks or speeds can prevent the system from posting, so match the speed, voltage and registered type of any modules you keep.

How can I confirm the 64 GB kit is recognised and ECC is active after installation?

Enter the BIOS or UEFI and check the memory information screen; it should show 64 GB total across two 32 GB DIMMs at 2133 MT/s with ECC enabled. Operating-system tools such as dmidecode or Windows System Information will also report the capacity, speed and ECC status.

What is included in the box and do I need anything else to install it?

The package contains two 32 GB 288-pin DDR4 LRDIMMs. No cables, brackets or additional components are supplied; ensure your server has two free DDR4 DIMM slots that support registered ECC memory.
