Server ECC RDIMM for Samsung replacement

This 4GB DDR3 registered module operates at 1866MHz with CL13 latency and 1.5V standard voltage. It uses a 1Rx4 configuration with Samsung chipset and fits 240-pin DIMM slots. Designed as a compatible replacement for Samsung M393B5270QB0-CMA in server and workstation systems.

Thermals and power in normal use

Standard 1.5V DDR3 voltage keeps power draw low during typical server workloads. Registered buffering reduces electrical load on the memory controller for stable operation. No active cooling is required on the module itself under normal conditions.

Deciding specification — registered ECC

The module is an ECC RDIMM with registered buffering; it will not work in platforms that require unbuffered non-ECC UDIMMs. Verify your system specifically supports registered ECC DDR3 before purchase. Builders needing unbuffered memory or a different DDR generation must select another part.

Questions sur cet article

How do I install this 240-pin DDR3 RDIMM and which step do people often miss?

Align the notch on the module with the slot key, press firmly until both side clips click shut, and verify the system registers the full 4 GB capacity at 1866 MHz in BIOS.

What maintenance or replacement will this ECC RDIMM need later?

No routine maintenance is required; if a correctable error count rises over time, replace the module to maintain data integrity.

What limit appears first under sustained load with this 1.5 V CL13 module?

The registered buffer adds one cycle of latency, so memory-controller throughput ceiling is reached before the DRAM chips hit thermal limits.
