16GB DDR4 2400 ECC RDIMM for HP servers

This 16GB DDR4 2400 registered DIMM delivers error-correcting memory for compatible HP server and workstation platforms. The module operates at PC4-19200 speed with CL17 latency and 1.20V standard voltage. It suits administrators upgrading validated HP part numbers such as 852264-001 or T9V40AA.

Sustained load behaviour with registered ECC

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC circuitry detects and corrects single-bit errors in real time without halting the system. The 2Rx4 organisation supports stable throughput under long-running server workloads.

DDR4 2400 interface practical limits

The DDR4 2400 interface caps peak bandwidth at the PC4-19200 rate regardless of module capacity. Registered DIMMs require a motherboard with registered memory support; they will not function in unbuffered consumer boards. Verify your platform accepts 288-pin RDIMMs before installation.

Questions sur cet article

How much power does this 1.20V DDR4 2400 RDIMM draw under sustained server load?

This module operates at the standard DDR4 voltage of 1.20V. Actual power draw depends on your platform and workload, but registered DIMMs at this voltage are designed for efficient continuous operation in servers.

Does my motherboard need to support ECC and registered DIMMs to use this 288-pin module?

Yes. This is an ECC RDIMM (Registered DIMM). Your system must support both ECC and registered memory, and provide a 288-pin DDR4 DIMM slot, for the module to function.

Will this CL17 2Rx4 stick work alongside older DDR4 modules in the same channel?

Mixing modules with different speeds, latencies, or ranks can cause instability. For best reliability, populate channels with identical 16GB DDR4 2400 CL17 2Rx4 RDIMMs.
