A-Tech 4GB DDR3L 1333MHz ECC RDIMM

This is a new A-Tech 4GB DDR3L 1333MHz ECC Registered DIMM built as a compatible replacement for Hynix HMT351V7CFR4A-H9 and HMT351V7BFR4A-H9 modules. It operates at 1.35V with CL9 latency and a 1Rx4 rank configuration using major brand chipsets. The 240-pin DDR3 DIMM form factor fits server and workstation boards that accept registered ECC memory.

Suits servers needing low-voltage registered ECC

Systems that require registered ECC DDR3L memory at 1333MHz with a 1.35V operating voltage can use this module to add 4GB per slot. It is not for platforms that only accept unbuffered UDIMMs or modules with a different rank organisation. Buyers whose hardware demands a higher per-module capacity or a different DDR generation must select a different part.

Registered ECC with 1Rx4 organisation

The single specification that decides fit is the registered ECC design combined with a 1Rx4 rank layout on a 240-pin DDR3L interface. Only motherboards qualified for registered ECC DDR3L at this speed and rank will post correctly with this module installed.

Questions about this item

Should I pick the 4GB DDR3L 1333MHz ECC RDIMM or a different capacity for my server?

This listing is a single 4GB module (1Rx4) running at DDR3L 1333MHz with CL9 latency; choose it when your system requires a registered ECC DIMM at 1.35V and you need exactly 4GB per slot.

What does the DDR3L 1333MHz (PC3L-10600) rating mean once the module is installed?

The module operates at 1333MT/s with CL9 timing at 1.35V, delivering registered ECC error correction for stable server workloads within the DDR3L standard.

Does the 240-pin DDR3L RDIMM interface limit the speed or voltage in practice?

The 240-pin DDR3L RDIMM form factor locks operation to 1.35V and the DDR3L 1333MHz (PC3L-10600) data rate; it will not run at higher DDR3 voltages or speeds.
