4GB DDR4 2400 SODIMM Module

This Computer Memory Solutions module provides 4GB of DDR4 system memory in a 260-pin SODIMM form factor. It operates at 2400 MHz with a PC4 19200 rating and runs on a standard 1.2V supply. The kit contains a single unbuffered, non-ECC stick built with major brand components.

Laptop upgrades needing a single stick

The 2Rx8 dual-rank layout suits notebooks and small-form-factor PCs that accept DDR4 SODIMMs. Buyers who need more than 4GB of total capacity should look at larger modules or a matched pair kit. Systems requiring ECC error correction or registered buffering are not compatible with this part.

Dual-rank 2Rx8 organisation

The module uses a 2Rx8 configuration, meaning two ranks of x8 chips are present on the board. This rank structure affects how the memory controller addresses the module and can influence maximum supported capacity per slot. Verify that your platform accepts 2Rx8 SODIMMs before purchase.

Questions about this item

How can I confirm the module is running at 2400 MHz after installation?

Enter the BIOS or use a system-information tool such as CPU-Z to verify the memory frequency reads 2400 MHz and the CAS latency shows 17-17-17.

What items are included and is anything else required?

The box contains one 4 GB DDR4 260-pin SODIMM module; no additional parts are needed if your laptop has a free SODIMM slot.

Should I choose the 2Rx8 version or a 1Rx8 alternative?

This module is 2Rx8; if your system already has a 1Rx8 stick, adding this 2Rx8 module will work but the system will run at the slower of the two configurations.
