16GB DDR4 2133 ECC LRDIMM for Servers

This 16GB DDR4 2133 module is a load-reduced ECC DIMM built for server and workstation platforms. It runs at PC4-17000 speed with CL15 latency and standard 1.20V operation. The 2Rx4 organisation and 288-pin form factor match the Micron MTA36ASF2G72LZ-2G1 and MTA36ASF2G72LZ-2G1A1 part numbers. Major-brand chips and full testing aim to deliver dependable uptime in compatible systems.

Suited for ECC LRDIMM slots needing 16GB at 2133MHz

Administrators expanding memory in qualified servers that accept DDR4 2133 ECC LRDIMM modules will find this a direct replacement. Builders whose platforms require registered DIMMs, unbuffered DIMMs, or a different voltage should look elsewhere. Systems limited to lower densities per slot or a different rank configuration cannot use this module. Always confirm the motherboard qualified-vendor list before ordering.

16GB capacity handles moderate virtualization

A single 16GB LRDIMM adds meaningful headroom for virtual machines, in-memory databases, and large-file processing on supported hardware. Workloads that demand higher per-slot density or faster transfer rates will exhaust this module’s capacity or bandwidth. The 2133MHz data rate and CL15 timing set the performance ceiling for memory-bound tasks.

Questions about this item

My server requires ECC LRDIMM 2Rx4 modules at 2133 MHz — does this A-Tech 16GB DDR4 stick match that exact specification?

Yes, this module is a 16GB DDR4 2133 (PC4-17000) ECC LRDIMM with 2Rx4 organisation, CL15 latency and 1.20V operation, matching the required specification.

I still have older DDR4 2133 RDIMMs installed; can I mix them with this Load Reduced DIMM in the same system?

Mixing LRDIMM and standard RDIMM modules is not supported on most platforms; the memory controller expects a single DIMM type per channel, so you should replace all modules with matching LRDIMMs.

After installing the module, how can I verify it is running at the correct 2133 MHz speed and ECC is active?

Enter the system BIOS or UEFI and check the memory information screen — it should report 2133 MT/s, 16GB capacity, ECC enabled and the correct 2Rx4 rank configuration.
