32GB DDR3L ECC LRDIMM module

This 32GB DDR3L ECC LRDIMM module is built for servers and workstations that require registered load-reduced memory. It operates at 1600MHz with a CAS latency of CL11 and runs at 1.35V low voltage. The 4Rx4 organisation helps increase capacity per channel on supported platforms.

Verify DDR3L LRDIMM support and pin count

Confirm that your system accepts DDR3L LRDIMM modules and supports 4Rx4 rank configurations before ordering. The module uses a 240-pin DIMM form factor and requires a motherboard qualified for load-reduced ECC memory at 1.35V. Check the vendor memory-qualified list for the exact Micron part numbers referenced.

Sustained load stability with ECC correction

Under continuous workloads the ECC circuitry detects and corrects single-bit errors to maintain data integrity. Load-reduced buffering reduces electrical loading on the memory bus, allowing stable operation at 1600MHz across fully populated channels. The 1.35V operation helps limit thermal output during extended duty cycles.

Questions about this item

Does the 32GB DDR3L 1600 ECC LRDIMM 4Rx4 module come alone or with extra parts?

The listing is for a single 32GB module. No brackets, cables or additional components are included.

How do I know which version to pick between the two Micron part numbers shown?

Both Micron part numbers MT72KSZS4G72LZ-1G6E2A7 and MT72KSZS4G72LZ-1G6E2A7BE are covered by this A-Tech module; choose the one that matches your system's service tag.

What does the CL11 1.35V spec mean when the stick is installed in a server?

CL11 is the CAS latency at DDR3L 1600 speed, and 1.35V is the low-voltage operating level that reduces power draw while keeping ECC and load-reduced operation active.
