64GB DDR4 ECC RDIMM kit

This 64GB kit contains two 32GB DDR4 2133MHz CL15 registered ECC RDIMMs built for servers, workstations and NAS systems. The modules operate at 1.2V and use a 288-pin 2Rx4 layout compliant with JEDEC PC4-17000 specifications. They are intended for multi-channel server platforms that require registered memory with error correction.

Installing registered ECC RDIMMs

Installation follows standard DIMM seating procedure, but the modules must go into slots that support registered ECC memory. Mixing these registered sticks with unbuffered memory will prevent the system from booting. Standard desktop motherboards and consumer laptops do not accept registered DIMMs, so verify platform compatibility before purchase.

Sustained server workload behaviour

Under continuous load the registered buffer reduces electrical stress on the memory controller, helping maintain signal integrity across all ranks. ECC corrects single-bit errors on the fly, preventing data corruption during long compute or storage tasks. The 1.2V operation keeps power draw predictable for dense multi-DIMM configurations.

Questions sur cet article

How can I confirm the 2133 MHz CL15 ECC registered kit is running at the rated speed after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report 2133 MHz, CL15 timings and ECC registered status for both 32 GB modules.

What comes in the box and is anything else required to install the 2 x 32 GB RDIMMs?

The kit includes two 32 GB 288-pin DDR4 ECC registered DIMMs; no extra cables, brackets or heat spreaders are needed, just compatible server or workstation DIMM slots.

Which capacity version should I choose if my server supports 64 GB across two channels?

This 64 GB dual-channel kit provides two 32 GB modules, matching a two-channel 64 GB configuration exactly.
