64 GB DDR4 2133 ECC Registered kit

This 64 GB kit contains two 32 GB DDR4 2133 modules built for server platforms. Each module is an ECC registered LRDIMM using a 4Rx4 organisation and a 288-pin interface. The PC4 17000 rating matches the 2133 MT/s data rate. It is sold new and targets administrators who need error-correcting memory for multi-socket systems.

Suited to servers needing registered ECC DIMMs

The registered buffer and ECC make this kit appropriate for workloads that demand data integrity and signal stability across multiple ranks. Systems that require unbuffered non-ECC memory, consumer desktop boards, or laptops cannot use these modules. Buyers who need higher speeds or lower latency for single-threaded applications should look elsewhere.

64 GB total capacity in a dual-channel pair

Two 32 GB LRDIMMs provide 64 GB of addressable memory per populated channel, giving headroom for virtualisation hosts, database buffers and large in-memory datasets. The 4Rx4 rank density maximises capacity per slot but increases electrical loading, so total system capacity is limited by the motherboard's registered DIMM slot count and memory controller rank limits.

Questions about this item

Will this 288-pin DDR4 2133 registered ECC kit work in my motherboard that only accepts unbuffered non-ECC modules?

No, the modules are registered with ECC and require a motherboard chipset and CPU that explicitly support registered ECC DDR4; they will not function in consumer boards limited to unbuffered non-ECC memory.

Can I mix these 4Rx4 LRDIMMs with existing 2Rx4 RDIMMs already installed in my server?

Mixing 4Rx4 load-reduced DIMMs with 2Rx4 registered DIMMs is not supported by any major server platform; the memory controller treats the electrical loading and rank architecture differently, so all slots must use identical LRDIMM modules.

How can I verify the kit is running at the rated DDR4 2133 speed after installation?

Enter the system BIOS or UEFI and confirm the memory frequency reads 2133 MT/s (PC4 17000) with ECC enabled; most server management consoles such as iDRAC, iLO or IPMI will also report the correct speed and ECC status per DIMM.
