SK hynix 4 GB DDR4-3200 UDIMM

This module is a single 4 GB DDR4 UDIMM rated at 3200 MT/s with CL22 latency. It operates at 1.2 V and uses the standard 288-pin desktop form factor. The part is unbuffered and non-ECC, making it a straightforward drop-in upgrade for compatible boards.

Suits budget builds or simple capacity additions

Systems that need only a modest capacity increase will find this 4 GB stick adequate. Builders targeting dual-channel performance should add a second identical module. Users requiring ECC error correction, registered buffering, or higher single-module density must select a different specification.

3200 MT/s DDR4 speed rating determines fit

The module runs at DDR4-3200 (PC4-25600) with a CAS latency of 22. A motherboard that cannot accept DDR4 at this data rate will not work with this part. Verify the board's supported memory speeds before purchase.

商品問答

Does the 1.20 V operating voltage of this DDR4-3200 module keep heat and power draw low during all-day use?

Yes — at the standard 1.20 V the 4 GB stick draws minimal power and runs cool enough for continuous desktop workloads without extra cooling.

What motherboard slot and memory controller do I need to install this 288-pin UDIMM?

A desktop board with a DDR4 memory controller and a free 288-pin DIMM slot is required; the module is unbuffered and non-ECC, so it fits standard consumer sockets.

Will the CL22 DDR4-3200 stick down-clock automatically when paired with slower DDR4 modules already in my system?

The module follows JEDEC SPD profiles, so the memory controller will negotiate the highest common speed and latency across all populated slots.
