Server-grade 16GB DDR3L module

This A-Tech 16GB DDR3L 1866MHz ECC RDIMM is a registered dual-rank module built with Samsung chipset. It operates at 1.35V low voltage with a CAS latency of CL13 and uses the 240-pin DIMM form factor for server and workstation platforms.

Suits ECC registered memory slots only

The module is designed for systems that require ECC registered DDR3L memory at 1866MHz. It will not work in desktop boards that accept only unbuffered non-ECC UDIMMs or in platforms limited to 1.5V standard DDR3 voltage.

Registered ECC with 2Rx4 organisation

The single specification that decides fitment is the registered ECC 2Rx4 organisation at 1.35V; the motherboard must explicitly support registered ECC DDR3L RDIMMs of this rank configuration.

Questions about this item

Should I choose the 16GB DDR3L 1866 ECC RDIMM or a different capacity?

This module provides 16GB in a single 2Rx4 registered DIMM; add multiple identical modules to reach your system's maximum supported capacity.

What does the DDR3L 1866 (PC3L-14900) speed rating deliver in my server?

The module runs at 1866 MT/s with CL13 latency at 1.35V, giving your memory controller the specified data rate and timing for registered ECC operation.

How does the 240-pin DDR3L RDIMM interface limit performance?

The 240-pin registered DDR3L interface caps the module at 1866 MT/s and 1.35V, so bandwidth and latency are fixed by this generation's electrical and signalling limits.
