8GB DDR4 2400 ECC RDIMM for Servers

This registered DIMM provides 8GB of ECC memory for server and workstation systems that require error correction. It operates at DDR4 2400 speed with CL17 latency and 1.20V voltage. The module uses a 1Rx8 organisation and major brand chips. It is a compatible replacement for the Samsung M393A1K43BB0-CRC part.

DDR4 2400 Registered DIMM Limits

DDR4 2400 registered memory requires a platform that supports ECC RDIMMs and the PC4-19200 data rate. The registered buffer adds one clock cycle of latency compared to unbuffered modules. Systems limited to lower DDR4 speeds will downclock this module automatically. Non-server boards that lack registered DIMM support cannot use this memory.

Simple 288-Pin DIMM Installation

Installation follows the standard 288-pin DIMM procedure: align the notch, press firmly until the retention clips engage, and verify seating. The most common issue is mixing registered and unbuffered modules in the same system, which prevents boot. Always confirm the motherboard qualification list before purchase to avoid compatibility mismatches.

Questions about this item

Should I choose the 8GB DDR4 2400 ECC RDIMM 1Rx8 module or a different capacity?

This listing is for a single 8GB DDR4 2400 ECC RDIMM 1Rx8 module. Select it if your server needs one 8GB stick; add multiple units to reach the total capacity your motherboard supports.

What does the 2400MHz PC4-19200 rating mean once the module is installed?

The module runs at 2400MHz with a peak transfer rate of PC4-19200. Actual throughput depends on your platform's memory controller and how many DIMM slots are populated.

How does the DDR4 288-pin registered ECC interface limit performance in practice?

The 288-pin DDR4 RDIMM interface uses a register to buffer address and command signals, enabling stable ECC operation at 2400MHz. Maximum bandwidth is capped by the PC4-19200 specification and your system's memory controller.
