Server memory upgrade for Micron systems

This A-Tech module provides 32GB of DDR4 ECC registered memory rated at 2133MHz with CL15 latency. It operates at the standard 1.20V and uses a 2Rx4 rank configuration on a 288-pin DIMM. The Micron chipset ensures reliable operation in server and workstation environments.

Suited for administrators expanding compatible

This module suits IT teams adding capacity to systems that accept DDR4 2133MHz ECC RDIMMs with a 2Rx4 layout. It is not for desktop PCs or laptops that require unbuffered non-ECC memory. Buyers who need higher frequencies, different rank structures, or larger single-module capacities should look at other specifications.

Verify platform requirements before ordering

Confirm that your motherboard supports DDR4 2133MHz registered ECC DIMMs and accepts a 2Rx4 rank configuration. Check the maximum memory per slot and total system capacity allowed by the BIOS. Ensure the 288-pin form factor matches the available slots and that the 1.20V voltage is within the platform specification.

Questions about this item

Does my server need a 288-pin DDR4 RDIMM slot to accept this 32GB module?

Yes, the module is a 288-pin DDR4 RDIMM, so the motherboard must provide a matching registered DIMM slot.

Can I mix this CL15 2Rx4 stick with existing CL15 1Rx4 modules in the same channel?

Mixing ranks is possible if the platform supports it, but the memory controller will run all modules at the slowest common timing.

How can I confirm the module is running at 2133 MHz with ECC active after installation?

Check the BIOS memory information or use a tool such as CPU-Z to verify 2133 MT/s, CL15 timings and ECC status.
