8GB DDR4 ECC UDIMM for Server Upgrades

This 8GB DDR4 2133MHz ECC unbuffered DIMM is built as a compatible replacement for Micron MTA18ASF1G72AZ-2G1A1 and MTA18ASF1G72AZ-2G1B1 modules. It targets administrators upgrading or repairing server and workstation platforms that require error-correcting memory at standard voltage. The 2Rx8 organisation and 288-pin form factor match the original Micron specification. Systems needing registered or load-reduced DIMMs cannot use this module.

Capacity and headroom at DDR4 2133

The single 8GB rank provides 8GB of addressable capacity per slot with CL15 latency at the PC4-17000 data rate. It handles typical virtualisation workloads, database buffers and multi-user application tiers within that footprint. Workloads that exceed 8GB per channel or demand higher bandwidth than 2133MT/s will saturate the module. The 2Rx8 layout offers standard density for dual-channel population.

Thermals noise and power at 1.20V

Operating at the DDR4 standard 1.20V, the unbuffered module draws minimal power and generates low heat inside chassis with directed airflow. No active cooling is required on the DIMM itself. Silent operation is inherent because the module has no moving parts. Power draw scales with utilisation but remains within the standard DDR4 envelope for this density and speed.

Questions about this item

Will this DDR4 2133 CL15 ECC UDIMM run at 2133 MHz when installed next to DDR4 2133 modules I already own?

Yes, identical speed and latency ratings mean the modules will operate together at DDR4 2133 without forcing a lower frequency.

How can I confirm the module is running as ECC unbuffered at CL15 after installation?

Check the BIOS memory information or a tool like CPU-Z; it should report 8 GB, DDR4 2133, CL15, 1.20 V and ECC unbuffered.

Does the 288-pin DIMM arrive alone, or are extra parts such as a heatsink or cable included?

The box contains the single 8 GB 2Rx8 DDR4 2133 ECC UDIMM only; no heatsink, cable or additional hardware is supplied.
