8GB DDR4 2133MHz Desktop Module

This single 8GB DDR4 module runs at 2133MHz with CL15 latency and standard 1.2V operation. It uses a 288-pin unbuffered DIMM form factor built with major brand chips. The kit is designed as a direct replacement for Crucial CT8G4DFS8213 and equivalent part numbers. Quality testing ensures dependable performance in compatible desktop systems.

Suits Standard DDR4 Desktop Upgrades

This module fits owners of desktops that officially support DDR4 2133MHz non-ECC unbuffered memory. It works for both AMD and Intel platforms that accept this speed and voltage. Buyers needing ECC, registered, or higher-frequency modules should select a different part. Always confirm your motherboard specifications before purchasing to avoid incompatibility.

Deciding Spec Is DDR4 2133MHz Non-ECC UDIMM

The single specification that determines fit is the DDR4 2133MHz non-ECC unbuffered DIMM standard at 1.2V. Your system must explicitly support this exact speed, voltage, and module type. If the board requires ECC, registered, or a different DDR generation, this module will not function. Verify the memory QVL or manual to match these parameters precisely.

Questions about this item

How can I confirm the module is running at the advertised 2133 MHz CL15 after installation?

Open the BIOS or a tool such as CPU-Z and verify the memory frequency reads 2133 MHz with timings of 15-15-15 and voltage at 1.20 V.

What exactly ships in the box and is anything else required to install it?

The package contains one 8 GB 288-pin DDR4 DIMM; no extra cables, brackets or software are needed — just a free desktop memory slot.

Should I choose the 8 GB single stick or a kit if my system supports dual-channel?

This listing is a single 8 GB module; buy two of the same part number to populate paired slots for dual-channel operation.
