Server ECC Registered DIMM Kit

This 64GB kit contains four 16GB DDR4 2133MHz ECC registered DIMMs built for the Dell PowerEdge R730xd. Each module runs at 1.2V with CL15 timing and a 2Rx4 organisation. The 288-pin registered design adds a buffer that reduces electrical load on the server memory controller. It is not for systems that require unbuffered UDIMMs or LRDIMM-only configurations.

Sustained Load Behaviour

Registered modules place a register between the DRAM and the memory controller, which steadies signal integrity when all 24 DIMM sockets are populated across two CPUs. ECC corrects single-bit errors and detects multi-bit errors during continuous operation. The 2133MHz data rate and CL15 latency deliver consistent throughput for virtualisation and database workloads.

Platform Capacity Limits

The PowerEdge R730xd supports up to 384GB of registered ECC RDIMMs or 768GB of LRDIMMs. Twelve sockets are available per CPU for a total of 24 sockets in a dual-processor layout. This 64GB kit occupies four of those sockets and leaves room for further expansion within the platform maximum.

Questions about this item

How much power does the 1.2V DDR4 2133MHz registered kit draw when the server runs continuously?

Each module operates at 1.2V; the four 16GB sticks give 64GB total at DDR4-17000 speed with CL15 timings.

What must the Dell PowerEdge R730xd already have for this 288-pin ECC registered memory to work?

The system needs free 288-pin RDIMM slots — up to 12 per CPU, 24 with two CPUs — and a maximum capacity of 384GB for registered ECC modules.

Will this CL15 2Rx4 kit run alongside older DDR4 RDIMMs already installed in the R730xd?

Yes, if the existing modules are also DDR4 ECC registered DIMMs; the server will clock all sticks to the lowest common speed and timing.
