HPE 16GB DDR4 Registered DIMM

This HPE memory module delivers 16GB of DDR4 capacity in a registered DIMM format. It suits servers and workstations that require error-correcting registered memory for stable operation. The module follows the DDR4-2933 standard with CL21 latency. Buyers needing unbuffered desktop memory should choose a different part.

Registered signal processing and CL21 latency

The module uses registered signal processing, which places a register between the DRAM and the memory controller. This characteristic determines compatibility with platforms that mandate registered DIMMs. Systems expecting unbuffered modules will not support this part.

288-pin DIMM installation

Installation follows the standard 288-pin DIMM procedure: align the notch, press firmly until the retention clips engage. A common issue is mixing registered and unbuffered DIMMs in the same channel, which prevents the system from posting. Verify the platform requires registered memory before fitting.
