8GB DDR4 2133MHz Desktop Module

This A-Tech module provides eight gigabytes of DDR4 memory running at 2133MHz with CL15 latency. It is built as a non-ECC unbuffered DIMM using major-brand chips and operates at the standard 1.2V. The stick suits desktop owners who need a straightforward capacity increase for everyday multitasking.

288-Pin DIMM Fits Standard Slots

The 288-pin form factor slots into any desktop motherboard that accepts DDR4 UDIMMs. Because it is unbuffered and non-ECC, it works with mainstream consumer platforms without requiring registered-memory support. The single 8GB stick leaves additional slots free for future expansion if the board has more than one DIMM socket.

Replaces Crucial CT2K8G4DFD8213 CT8G4DFD8213

This module serves as a direct replacement for the listed Crucial part numbers. The upgrade makes sense when a system currently runs less than 8GB or when a matching stick is needed to complete a dual-channel pair. Verifying the motherboard’s supported speed and maximum capacity beforehand ensures the new RAM will be recognised at its rated 2133MHz.

Questions about this item

Will the CL15 latency limit throughput during sustained workloads?

CL15 is the rated CAS latency at 2133 MHz; sustained performance will follow this timing as long as the motherboard runs the module at its specified 1.20 V and the memory controller supports DDR4-2133.

How much heat or noise should I expect when the module runs all day?

The DIMM operates at the standard 1.20 V DDR4 voltage with no active cooling; it produces minimal heat and no audible noise under continuous use.

What must my desktop already have for this 288-pin DDR4 stick to work?

A motherboard with a DDR4 288-pin DIMM slot that supports 2133 MHz unbuffered non-ECC memory at 1.20 V.
