4 GB DDR4 DIMM

This SK hynix module is a single 4 GB DDR4 DIMM built for desktop systems. It uses a 288-pin interface and runs at DDR4-2400 speed with a PC4-19200 bus rating. The stick is organised as 1Rx16 and ships as a standalone unit. It suits basic upgrades or replacement in compatible motherboards.

Fits standard DDR4 desktops.

The DIMM form factor fits regular desktop motherboards that accept DDR4 memory. It will not work in laptops or small-form-factor boards that require SO-DIMM modules. Builders needing more than 4 GB of total memory should add additional sticks or choose higher-capacity modules. Systems limited to lower DDR4 speeds will still run this module at the board's maximum supported rate.

DDR4-2400 bus speed decides compatibility

The module operates at a PC4-19200 (DDR4-2400) bus speed, which is the single specification that determines whether it matches your motherboard's memory controller. Verify that your platform supports this data rate before purchase. If the board only runs at a different DDR4 speed, the module will downclock to the highest common setting.

Questions about this item

What comes in the box and what else do I need to buy?

The package contains a single 4 GB DDR4 DIMM with 288 pins. No extra cables or brackets are required; install it directly into a compatible motherboard slot.

How do I decide between the listed versions or capacities?

This module is a 1Rx16 4 GB stick rated at DDR4-2400 (PC4-19200). Choose it when you need exactly 4 GB of DDR4 memory at that speed.

What does the DDR4-2400 rating mean once the RAM is installed?

It indicates a peak transfer rate of 19200 MB/s at 2400 MT/s. Actual throughput depends on the memory controller and whether the system runs in single- or dual-channel mode.
