Capacity 64GB (4 x 16GB)

  • 64 GB capacity lets servers handle larger workloads with four 16 GB modules
  • ECC registered design detects and corrects data errors for reliable operation
  • DDR4 2133 MHz speed at CL15 reduces latency during intensive tasks
  • 2 V standard voltage lowers power draw per module
  • Quad-channel kit with 288-pin RDIMM form factor fits compatible server platforms

Server Memory Kit

This 64GB kit contains four 16GB DDR4 2133 MHz registered DIMMs with ECC and single-rank x4 organisation. It is built for servers and workstations that require error-correcting registered memory.

Compatibility Check

Verify that your system supports DDR4 2133 ECC RDIMM modules in a 288-pin form factor and accepts single-rank x4 configuration. Confirm the maximum capacity per slot and the supported channel population rules in your hardware manual before ordering.

Target Users

Suits administrators upgrading compatible DDR4 servers or workstations that need registered ECC memory for data-integrity workloads. Not for desktop or laptop owners, nor for systems that require unbuffered non-ECC DIMMs or a different DDR generation.

Questions about this item

What comes in the 64 GB kit and is anything else needed to install it?

The kit contains four 16 GB DDR4 2133 MHz ECC RDIMM modules. No extra parts are required if your server or workstation has four free 288-pin DIMM slots.

Why choose the 1Rx4 single-rank version over other ranks?

1Rx4 modules place all memory chips on one rank, reducing electrical load on the memory controller and allowing higher capacities per channel on compatible server platforms.

What does the PC4-17000 rating mean for real-world server performance?

PC4-17000 indicates a peak transfer rate of 17 000 MB/s at 2133 MHz with CL15 latency, giving registered ECC bandwidth suited for multi-threaded server workloads.
