Capacity 64GB (8 x 8GB)

  • 64 GB kit of eight 8 GB modules for high-capacity server workloads
  • DDR4 3200 MHz speed with CL22 latency for fast data throughput

  • Single-rank 1Rx8 organisation optimises signal integrity on registered channels
  • 2 V standard DDR4 voltage reduces power draw per module

64GB DDR4 ECC RDIMM kit

This 64GB kit contains eight 8GB DDR4 registered DIMMs rated at 3200 MHz with CL22 latency and 1.2V operation. It is built for servers and workstations that require ECC error correction and registered signalling, not for desktop or laptop platforms.

Registered DIMM build and 288-pin layout

Each module uses a single-rank 1Rx8 organisation with major-brand chips and a 288-pin DIMM form factor. Registered buffering reduces electrical load on the memory controller, allowing stable operation in high-density configurations, while ECC detects and corrects single-bit errors to protect data integrity.

Replaces non-ECC or lower-capacity DDR4 kits

The upgrade suits administrators who need the full 64GB capacity with registered ECC support for virtualisation, database or compute workloads. It is not for systems that accept only unbuffered UDIMMs or that lack DDR4 registered-memory support.

Questions about this item

What speed does the DDR4 3200 PC4-25600 interface run at in practice?

The kit operates at DDR4 3200 MHz, rated as PC4-25600, with CAS latency 22 and 1.2 V.

What physical slot and clearance does this 288-pin RDIMM need?

It fits a standard DDR4 288-pin DIMM slot; the registered design adds a buffer chip, so verify your server or workstation supports RDIMMs and has enough height clearance.

How do I install the eight 8 GB modules, and what step is often missed?

Populate all eight slots following the motherboard channel guide, seat each RDIMM until the latches click, and enable ECC in BIOS — skipping the BIOS step leaves error correction inactive.
