Targeted DDR4 SODIMM for Vivobook X Series

This 8 GB DDR4 2400 module is built specifically for ASUS Vivobook X550VX, X555BP, X555QG and X556UA notebooks. It suits owners of those models who need a straightforward capacity increase for everyday multitasking and office workloads.

260-pin unbuffered stick with major-brand chips

The single-rank 2Rx8 layout runs at 1.2 V with CL17 17-17-17 timings and no heat spreader, keeping the profile low for tight laptop slots. Non-ECC unbuffered design means it drops straight into the factory SO-DIMM socket without BIOS tweaks or pairing requirements.

Steps up from 4 GB or 8 GB factory configurations

Systems limited to 16 GB, 20 GB or 24 GB total capacity across one socket gain headroom for 64-bit operating systems and heavier browser tabs. Buyers who need more than the platform maximum or who require ECC registered memory should look elsewhere.

Questions about this item

Does the DDR4 2400 interface cap usable speed to 2400 MHz even if the laptop supports faster memory?

The module is rated DDR4 2400 (PC4 19200) with CL17 timing; the system will run all installed memory at the slowest module or CPU limit, so it cannot exceed 2400 MHz.

What physical slot and notch does the 260-pin SO-DIMM require?

It fits a standard 260-pin DDR4 SO-DIMM slot; the key notch position matches the DDR4 specification used in the listed Vivobook models.

How is the stick installed and what step is often missed?

Align the notch, insert the module into the SODIMM socket, then press down until the side retention clips lock; the step often missed is verifying both clips engage fully.
