64 GB DDR4 2133 ECC Registered LRDIMM

This module delivers 64 GB of DDR4 2133 memory with ECC registered operation in a 4Rx4 LRDIMM format. It is built for servers and workstations that require high-density error-correcting memory for virtualisation, database or compute workloads. The 288-pin form factor fits compatible DDR4 server platforms.

Compatibility checklist before ordering

Verify that your motherboard or server supports DDR4 2133 registered LRDIMMs and accepts 4Rx4 modules at this capacity. Check the vendor qualified-vendor list for this exact part number and confirm the maximum DIMMs per channel allowed by the platform. Ensure the system BIOS is current enough to initialise 64 GB registered modules.

Behaviour under sustained load

The integrated heat spreader helps dissipate heat during continuous operation at the rated 2133 MT/s speed. ECC registered signalling maintains data integrity across long-running workloads without the error accumulation seen in unbuffered modules. LRDIMM buffering reduces electrical load on the memory controller, supporting stable throughput when all slots are populated.

Questions about this item

Does the 64GB DDR4 2133 LRDIMM arrive as a single 288-pin module or must I buy additional sticks?

The product is a single 64GB 288-pin DDR4 SDRAM LRDIMM with heat spreader included; no extra modules are required for that capacity.

Should I choose the 4Rx4 registered ECC version or a different rank configuration for my server?

This module uses a 4Rx4 organisation with ECC and registered buffering, designed for high-density server platforms that support load-reduced DIMMs.

What does the PC4 17000 rating mean for actual throughput once installed?

PC4 17000 indicates a peak transfer rate of 17000 MB/s at the 2133 MT/s clock speed when the memory controller runs at that frequency.
