A-Tech 8GB DDR3L 1333 ECC RDIMM

This A-Tech module is an 8GB DDR3L 1333MHz registered DIMM built with Samsung components. It runs at 1.35V with CL9 latency and a 2Rx8 organisation. The 240-pin form factor fits server and workstation platforms that require ECC registered memory. It replaces Samsung part numbers M393B1G73BH0-YH9 and M393B1G73QH0-YH9.

Suited for ECC registered DDR3L systems

Administrators upgrading or repairing servers that specifically call for DDR3L 1333MHz ECC RDIMM modules at 1.35V will find this part a direct match. Builders whose platforms need unbuffered memory, a different voltage, a higher speed grade or a larger single-module capacity should look at other options.

Registered ECC with 2Rx8 organisation

The module presents a registered ECC interface with a 2Rx8 rank configuration, which the memory controller must support. Verify that your system's qualified-vendor list includes this exact organisation and voltage before ordering.

Questions about this item

How much heat and power does this 1.35 V DDR3L 1333 MHz module add when the server runs continuously?

The 1.35 V DDR3L voltage lowers power draw and heat output compared with standard 1.5 V DDR3, helping the system stay cooler during all-day workloads.

What motherboard slot and memory type must my system already provide for this 240-pin DDR3L ECC RDIMM to function?

Your board needs a DDR3 DIMM socket that accepts 240-pin registered ECC modules and supports 1.35 V low-voltage operation.

Can this 2Rx8 registered ECC DDR3L stick share channels with older single-rank DDR3 ECC DIMMs?

Mixing 2Rx8 registered modules with different-rank ECC DIMMs is possible only if the platform's memory controller explicitly allows mixed-rank populations; check the system manual before installing.
