Compatible Replacement for Samsung M392B1G73DB0-YK0

This A-Tech module is an 8GB DDR3L 1600 ECC Registered DIMM built as a compatible replacement for Samsung M392B1G73DB0-YK0. It runs at 1.35V with CL11 latency and a 2Rx8 organisation on a 240-pin form factor. The part is intended for server and workstation systems that specifically require DDR3L registered ECC memory.

Suited for DDR3L registered ECC slots only

Administrators maintaining or upgrading platforms that accept DDR3L 1600 RDIMMs at 1.35V can use this module to add 8GB per slot. Builders whose systems need unbuffered ECC, non-ECC UDIMMs, or a different voltage or pin count should select a different part.

240-pin DDR3L RDIMM form factor

The module fits only motherboards with 240-pin DDR3L Registered DIMM slots that support 1.35V operation. Verify the system’s memory specification for DDR3L RDIMM compatibility before purchase.

Questions about this item

Will this DDR3L 1600 ECC RDIMM run in a server that currently uses 1.5 V DDR3 registered modules?

The module operates at 1.35 V, so the platform must support DDR3L voltage; a board that only accepts 1.5 V DDR3 will not run it correctly.

How can I verify the stick is recognised as ECC registered after installation?

Check the BIOS memory information or run a tool such as dmidecode — it should report 8 GB, DDR3L 1600, ECC type Registered and 2Rx8 organisation.

Does the package include a single 8 GB DIMM or a kit of multiple sticks?

The box contains one 8 GB DDR3L 1600 ECC RDIMM (240-pin); no additional modules, brackets or cables are supplied.
