  • 288-pin 2Rx4 dual-rank x4 organisation optimises signal density for registered platforms

A-Tech 64GB DDR4 2133 ECC RDIMM Kit

This 64GB kit contains two 32GB DDR4 2133 MHz registered DIMMs built for servers and workstations that require ECC memory. Each module is a 2Rx4 dual-rank x4 design running at 1.2V with CL15 latency. The kit is not compatible with standard desktop or laptop platforms.

Fits DDR4 Registered DIMM Slots

The 288-pin RDIMM form factor installs only in systems that explicitly support DDR4 registered ECC memory. A dual-channel kit frees the remaining DIMM slots for future expansion while the registered buffer reduces electrical load on the memory controller. Verify your platform's qualified vendor list before installation.

Upgrades from Smaller DDR4 RDIMM Configurations

Replacing lower-capacity registered modules with this 64GB kit increases the memory available for virtualisation, databases and large datasets. The jump is worthwhile when workloads exceed the current installed capacity and the system board supports 32GB per slot at 2133 MHz.

Questions about this item

Will the 2133 MHz speed become the bottleneck when the server runs heavy workloads all day?

The modules run at 2133 MHz with CL15 latency, so sustained throughput is capped at that data rate regardless of load duration.

How much heat and power will a pair of 32 GB registered DIMMs add to a fully loaded chassis?

Each stick operates at the standard 1.2 V DDR4 voltage, keeping power draw and thermal output low for registered server memory.

Does my motherboard need to support registered ECC DDR4 and 288-pin DIMM slots for this kit to work?

Yes — the kit is DDR4 288-pin registered ECC RDIMM, so the board must accept registered ECC DDR4 in a dual-channel configuration.
