A-Tech 4GB DDR3L 1333MHz ECC RDIMM

This A-Tech module is a 4GB DDR3L 1333MHz ECC Registered DIMM built as a compatible replacement for the Samsung M392B5170FM0-YH9. It operates at 1.35V with CL9 latency and uses a 2Rx4 organisation on a 240-pin DDR3 DIMM form factor. Server and workstation administrators who need to match this exact part number for qualified hardware lists will find the specifications aligned.

Suited for Samsung M392B5170FM0-YH9 replacement

The module fits systems that specifically require the Samsung M392B5170FM0-YH9 part with DDR3L 1333MHz ECC Registered operation at 1.35V. Builders who need a different capacity, a non-ECC unbuffered DIMM, a different voltage such as 1.5V, or a different pin layout such as 262-pin cannot use this module. Compatibility must be verified against the system's qualified vendor list before purchase.

2Rx4 registered ECC at 1.35V decides fit

The single specification that determines whether this is the correct part is the combination of 2Rx4 registered ECC architecture with 1.35V DDR3L voltage at 1333MHz. Systems qualified for the Samsung M392B5170FM0-YH9 require this exact electrical and organisational profile; a module with a different rank structure, voltage, or buffering type will not function in those validated configurations.

Questions about this item

Will the 240-pin DIMM fit my server's memory slots?

The module uses a standard 240-pin DDR3 DIMM form factor, so it fits any server or workstation slot designed for DDR3 registered memory.

What is the correct way to seat the registered ECC module?

Align the notch with the slot key, press firmly until both retention clips click, and ensure the 1.35V DDR3L voltage matches your platform.

When should I replace this 4GB DDR3L RDIMM?

Replace it if memory diagnostics report uncorrectable ECC errors, the system fails to POST with this module installed, or you upgrade to a higher-capacity kit.
