Dell-Compatible DDR4 RDIMM

This 16 GB registered DDR4 module operates at 2933 MT/s with CL21 latency and 1.2 V power draw. It uses a 2Rx8 organisation and 288-pin form factor for Dell server and workstation platforms requiring ECC RDIMM memory.

Registered ECC limits

Registered ECC RDIMMs must be installed in motherboards that support registered buffered signalling and error-correcting code. They will not function in consumer desktop boards that accept only unbuffered non-ECC UDIMMs.

16 GB single-module capacity

The 16 GB density delivered in a single stick determines whether this part matches the slot population plan and total memory target for the specific Dell system being upgraded.

Questions about this item

Should I choose the 16GB single module or look for a different capacity?

This listing is a single 16GB module. If your Dell server or workstation has free 288-pin RDIMM slots, adding one 16GB stick increases total memory by 16GB.

What does the 2933MHz speed deliver in a real Dell server?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency. In a compatible Dell system it will operate at that rated frequency, providing the bandwidth and timing specified for registered ECC workloads.

How does the DDR4 RDIMM ECC interface limit what I can do?

The 288-pin registered DDR4 ECC design only fits motherboards that support registered ECC RDIMMs. It cannot be used in standard unbuffered desktop slots or in systems requiring load-reduced or non-ECC memory.
