Server-grade DDR3 8 GB module

This 8 GB DDR3 1866 MHz registered DIMM uses Samsung chipset and carries ECC error correction for data integrity in server and workstation environments. The module operates at standard 1.50 V with CL13 latency and a dual-rank 2Rx8 organisation. It is built as a compatible replacement for the Samsung M392B1G73DB0-CMA part number.

Verify DDR3 registered DIMM support

Confirm that your system accepts DDR3 registered ECC memory and provides 240-pin DIMM slots before ordering. The module requires a platform that can address registered buffers and ECC functionality; consumer desktop boards without these features will not recognise the stick. Check the vendor memory-qualified list for the exact part number or an equivalent 8 GB 1866 MHz registered specification.

Steady throughput under continuous load

Registered buffering and ECC correction maintain consistent data integrity during prolonged multi-threaded workloads such as virtualisation, database serving or rendering farms. The 1.50 V standard voltage and CL13 timing deliver stable bandwidth without the voltage drift seen in overclocked modules. Dual-rank organisation allows the memory controller to interleave accesses, sustaining throughput over extended periods.

Questions about this item

What comes in the box and do I need to buy anything else to install this 240-pin DDR3 module?

The box contains one 8GB DDR3 1866 ECC RDIMM. No extra parts are required; the module plugs directly into a compatible server DIMM slot.

How do I choose between the listed speed and capacity options for this Samsung M392B1G73DB0-CMA replacement?

This listing is a single 8GB module rated at DDR3 1866 (PC3-14900) with CL13 latency and 1.50V. Select it if your system needs exactly that specification.

What does the 1866 MHz rating mean once the RDIMM is running in my server?

The module transfers data at 1866 MT/s with CL13 timing at 1.50V, delivering PC3-14900 bandwidth when the platform supports DDR3 1866 registered ECC memory.
