4GB DDR4 2133 Desktop Module

This A-Tech module provides 4GB of DDR4 memory at 2133MHz with CL15 latency. It is built as an unbuffered, non-ECC DIMM for standard desktop systems. The 1.20V operating voltage matches the DDR4 standard. It serves as a direct replacement for Crucial CT2K4G4DFS8213 and CT4K4G4DFS8213 parts.

Replacing Slower or Smaller DDR4 Kits

The module upgrades systems running at lower DDR4 speeds or with less total capacity. A jump to 2133MHz CL15 is worthwhile when the platform supports this frequency natively. Verify the motherboard specification before purchase to ensure the rated speed is supported. The 288-pin form factor fits standard desktop DIMM slots.

Straightforward DIMM Installation

Installation requires aligning the notch on the 288-pin module with the slot key and pressing firmly until the retention clips engage. The most common issue is incomplete seating, which prevents the system from posting. Ensure the memory specification matches the board's supported configuration before installing. Modules undergo quality assurance testing for reliable operation.

Questions about this item

Will this 4GB DDR4 module fit a motherboard that specifies 288-pin unbuffered DIMM slots?

Yes, the module is a 288-pin DDR4 DIMM and is unbuffered, matching standard desktop slots.

My system runs at 1.2V DDR4; is this kit voltage-compatible?

The module operates at the standard 1.20V DDR4 voltage, so it matches 1.2V platforms.

Does the CL15 timing require any BIOS changes on a typical desktop board?

CL15 is the rated latency at 2133 MT/s; most boards apply it automatically via SPD.
