16GB DDR4 ECC UDIMM for Servers

This module delivers 16GB of DDR4 2133MHz memory with ECC error correction for server and workstation platforms. It operates at the standard 1.20V voltage and uses a 2Rx8 rank configuration with Micron chipset components. The unbuffered design suits systems that require UDIMM architecture rather than registered DIMMs. It serves as a compatible replacement for Micron part numbers MTA18ASF2G72AZ-2G1A1ZG and MTA18ASF2G72AZ-2G1B1.

288-Pin DIMM Build and CL15 Timing

The module uses a standard 288-pin DDR4 DIMM form factor for direct installation into compatible UDIMM slots. CAS latency is rated at CL15 for PC4-17000 operation at 2133MHz. Unbuffered construction means the memory connects directly to the memory controller without a register, which affects maximum supported capacity per channel on some platforms. All units undergo quality assurance testing before shipment to verify reliable performance.

Verify UDIMM Support and Slot Availability

Confirm that your system accepts DDR4 ECC unbuffered UDIMMs before ordering, as registered RDIMM or load-reduced LRDIMM modules are not interchangeable with this type. Check the motherboard or server documentation for maximum memory capacity per slot and total supported memory to ensure the 16GB density is supported. Ensure an available 288-pin DDR4 DIMM slot exists for installation. Systems requiring registered memory cannot use this module.

Questions about this item

Does the DDR4-2133 speed cap bandwidth at PC4-17000?

Yes, the module runs at DDR4-2133 which is rated PC4-17000, so maximum theoretical bandwidth is limited to that standard.

Will this 288-pin DIMM fit a standard server motherboard slot?

The stick uses the 288-pin DDR4 DIMM form factor, matching the keyed slot found on compatible server and workstation boards.

How do I install the module and what step is often missed?

Align the notch with the slot key, press firmly until both side clips click, then verify the system detects the full 16GB capacity in BIOS.
