A-Tech 8GB DDR3 1866 ECC RDIMM Server Memory

This 8GB DDR3 1866MHz PC3-14900 ECC Registered DIMM uses a 2Rx8 organisation and runs at 1.50V standard voltage with CL13 latency. It is built with major brand chips on a 240-pin form factor for server and workstation platforms. The module replaces Samsung M393B1G73BH0-CMA, M393B1G73EB0-CMA and M393B1G73QH0-CMA part numbers.

Suited for registered ECC DDR3 servers.

This module fits servers and workstations that require DDR3 Registered ECC memory with a 2Rx8 layout. It will not work in desktop or laptop boards that accept only unbuffered non-ECC DDR3, nor in systems limited to lower DDR3 speeds or different voltages. Buyers needing larger single-module capacities or newer DDR generations must select different memory.

Registered ECC DDR3 with 2Rx8 organisation

The Registered ECC design with 2Rx8 ranking is the decisive specification; the system memory controller must support registered operation and ECC error correction for this module to function. Verify the platform documentation for DDR3 RDIMM compatibility before ordering.

Questions about this item

Does my motherboard need 240-pin DDR3 slots that support registered ECC modules for this 8GB stick to work?

Yes — this module is a 240-pin DDR3 1866 registered ECC DIMM, so the board must accept registered ECC memory and provide standard 1.5 V DDR3 power.

Can I mix this 2Rx8 registered ECC module with older unbuffered non-ECC DDR3 DIMMs in the same server?

No — registered ECC and unbuffered non-ECC DIMMs use different signalling and cannot be installed together on the same memory channel.

How can I confirm the module is running at DDR3 1866 with CL13 after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report 1866 MT/s, CAS latency 13 and 1.5 V for this DIMM.
