4GB DDR4 2133 Desktop Module

This single 4GB DDR4 module runs at 2133MHz (PC4-17000) and fits standard 288-pin DIMM slots. It is built for desktop owners who need a straightforward capacity increase for everyday office work, web browsing and light multitasking.

Capacity and headroom

The 4GB stick adds enough space for a typical operating system plus several browser tabs and productivity apps. Heavier workloads such as video editing, modern gaming or running virtual machines will exceed the available memory and force the system to swap to storage.

Thermals noise and power draw

Operating at the standard 1.20V DDR4 voltage, the unbuffered non-ECC module produces minimal heat and requires no active cooling. It runs silently and adds only a small increment to the system's overall power consumption.

Questions about this item

Will this 288-pin DDR4 DIMM fit a standard desktop motherboard slot?

Yes — the module is a 288-pin unbuffered DDR4 DIMM, the standard form factor for current desktop boards.

My board runs memory at 1.2 V; does this kit match that voltage?

It operates at 1.2 V, which is the standard DDR4 voltage, so it will run at the correct level without adjustment.

Can I add this single 4 GB stick alongside an existing 4 GB module for dual-channel operation?

Yes — installing a matching 4 GB stick in the second channel slot will enable dual-channel mode, doubling memory bandwidth.
