Server memory kit

This 32GB kit contains two 16GB DDR4 2933MHz modules built to PC4-23400 CL21 specifications. They are ECC registered RDIMMs intended for server, workstation and NAS platforms that require registered memory. The kit is not compatible with standard desktop computers or unbuffered memory configurations.

Low voltage operation

Each module runs at 1.2V and conforms to JEDEC standard specifications for DDR4 registered DIMMs. The registered buffer reduces electrical load on the memory controller, supporting stable operation in multi-module server environments. No heat spreader is fitted on these modules.

Backward speed support

The memory is also compatible with 2133MHz, 2400MHz and 2666MHz systems, allowing deployment in older platforms without replacing the entire memory population. The dual-channel kit simplifies matched-pair installation for supported server and workstation boards.

Vragen over dit artikel

How do I install the 288-pin DDR4 ECC RDIMM modules and what step is often missed?

Align the notch on each 16 GB module with the slot key, press firmly until the retention clips click, then verify in BIOS that both channels show 2933 MHz CL21 at 1.2 V.

What maintenance or replacement will the 2Rx4 registered DIMMs need over time?

No routine maintenance is required; if a module fails the limited lifetime warranty covers replacement with an identical 16 GB 2Rx4 part.

What limit appears first when the dual-channel kit runs sustained workloads?

The CL21 latency at 2933 MHz and 1.2 V sets the throughput ceiling before thermal throttling becomes a factor.
