Server ECC RDIMM for HP systems

This 32 GB DDR4 2400 module is built for HP servers and workstations that require registered ECC memory. It replaces HP part numbers Q1V92A and 854596-B21 in compatible platforms. The single DIMM delivers 32 GB of capacity for memory-intensive workloads.

Registered 2Rx4 organisation at 1.2 V

The module uses a 2Rx4 rank configuration with CL17 latency and operates at the standard DDR4 voltage of 1.20 V. Registered buffering and ECC error correction are mandatory for the target HP platforms; systems that require unbuffered or non-ECC DIMMs will not accept this part.

Standard 288-pin DIMM installation

Installation follows the usual server DIMM procedure: power down, open the chassis, align the notch, and press until the ejectors lock. The most common issue is mixing registered ECC modules with unbuffered or non-ECC memory, which prevents the system from posting. Verify the server's qualified vendor list before adding this DIMM.

Questions about this item

Will the CL17 latency affect real-world responsiveness in my server?

CL17 means 17 clock cycles at 2400 MHz; the module delivers standard DDR4 latency for registered ECC workloads.

Does PC4-19200 limit the throughput I can expect from this DIMM?

PC4-19200 is the JEDEC peak rate for DDR4 2400; sustained throughput depends on the platform memory controller.

What physical slot does this 288-pin RDIMM require?

It fits a standard DDR4 288-pin RDIMM socket; the registered design needs a server or workstation motherboard that supports registered ECC memory.
