Capacity 64GB (8 x 8GB)

  • 64 GB total capacity across eight modules for high-density server workloads
  • DDR4 2933 MHz speed with PC4-23400 bandwidth for fast data throughput
  • ECC registered design with single-rank x8 organisation for error correction and signal integrity
  • 2 V standard DDR4 voltage for efficient power consumption
  • 288-pin RDIMM form factor fits compatible server and workstation memory slots

Server-grade capacity for multi-socket platforms

This 64 GB kit delivers eight 8 GB DDR4 registered DIMMs rated at 2933 MHz with CL21 latency. ECC and register circuitry protect data integrity in workloads that cannot tolerate silent corruption. The modules are built for servers and workstations that require registered memory; they will not function in desktop or laptop systems.

Standard-voltage operation at 1.2 V

Each module runs at the JEDEC-standard 1.2 V, keeping power draw predictable in fully populated chassis. Registered buffering reduces electrical load on the memory controller, which helps maintain stable thermals when all channels are filled. No additional cooling beyond normal server airflow is required for specified operation.

Replaces lower-capacity or non-ECC kits

Upgrading from smaller registered sets or unbuffered ECC modules adds the headroom needed for virtualization, large databases or compute clusters. The jump is worthwhile when the platform supports 2933 MHz registered DIMMs and the workload exceeds the current memory ceiling. Verify the system’s qualified-vendor list before installation.

Questions about this item

How do I install these 288-pin DDR4 RDIMMs, and what step do people often miss?

Insert each 1Rx8 module into the correct server DIMM slot following the manual’s channel order, then press firmly until the ejector clips lock; the step often missed is verifying the populated-channel sequence for registered memory.

What maintenance or replacement will this 64 GB kit need later?

No routine maintenance is required; if a module fails, replace the single 8 GB stick — ECC error logs will identify the faulty rank.

What limit appears first under sustained load with these CL21 1.20 V modules?

The CAS latency of 21 cycles at 2933 MHz sets the timing floor; sustained workloads hit that latency ceiling before voltage or thermal limits become a factor.
