Direct Kingston KVR21N15S6/4 Replacement

This A-Tech module matches the Kingston KVR21N15S6/4 specification exactly, delivering a 4GB DDR4 2133MHz CL15 DIMM at 1.2V. It installs in any desktop board that accepts a 288-pin unbuffered non-ECC stick.

Upgrade from lower capacity or slower DDR4

Adding this stick replaces a smaller module or a slower DDR4 DIMM, raising total memory and keeping the 2133MHz data rate. The jump is worth it when your system shows high memory usage during everyday multitasking or when the current stick limits the platform to a lower speed.

Suits budget desktop builds and simple repairs

The single 4GB rank works well for office PCs, home servers, or older platforms that only support 2133MHz DDR4. Builders needing higher frequencies, lower latencies, ECC, or larger capacities should look at other modules.

商品問答

Will this 4 GB DDR4 2133 MHz module fit a standard 288-pin desktop DIMM slot?

Yes, it is a 288-pin unbuffered DIMM designed for regular desktop memory slots.

Can I use this stick alongside existing DDR4 modules running at a different speed or latency?

The system will run all modules at the lowest common speed and highest latency; match 2133 MHz CL15 for best stability.

Does the 1.2 V operating voltage require any special BIOS setting or cooling?

No, 1.2 V is the standard DDR4 voltage and works at default BIOS settings without extra cooling.
