A-Tech 4GB DDR4 2133MHz UDIMM

This module is a 4GB DDR4 2133MHz UDIMM built for desktop computers. It targets users who need a straightforward memory upgrade to improve multitasking and system responsiveness. The non-ECC unbuffered design suits standard consumer motherboards.

DDR4 2133MHz PC4-17000 speed grade

The decisive specification is the DDR4 2133MHz rating, also labelled PC4-17000, with a tested frequency of 2133 and CAS latency of 15. Your motherboard must support this exact speed and voltage for the module to operate correctly.

1.2V standard voltage and 288-pin form factor

The module runs at the DDR4 standard 1.2V and uses the 288-pin DIMM form factor. These attributes ensure compatibility with DDR4 desktop slots without requiring special cooling or voltage adjustments.

Questions about this item

What does the 2133 MHz rating mean once this DDR4 module is installed in my desktop?

The 2133 MHz tested frequency sets the maximum data rate the memory controller will use by default, delivering PC4-17000 bandwidth for everyday desktop workloads.

How does the DDR4 2133 (PC4-17000) interface limit performance in practice?

The DDR4 2133 standard caps the module at 2133 MT/s and PC4-17000 peak throughput, so the system cannot run this stick faster without manual overclocking.

Will the 288-pin DIMM fit my motherboard's memory slots?

Yes, the 288-pin DDR4 DIMM form factor matches standard desktop DDR4 slots; verify your board supports DDR4 before installing.
