Asus X-Series Notebook Upgrade

This 8 GB DDR3L SODIMM module is built for Asus X555Lb, X555La and X554Lj-Xx104D notebooks. It targets owners of those models who need more memory than the factory-fitted 4 GB soldered RAM provides. The stick installs in the single user-accessible slot.

DDR3L 1600 CL11 1.35 V Unbuffered

The module runs at PC3L-12800 speed with 11-11-11 timings and a 2Rx8 organisation. Low-voltage 1.35 V operation matches the platform requirement, while the unbuffered, non-ECC design keeps latency low for everyday workloads. The 204-pin form factor is the only one that fits the socket.

Single-Slot Expansion Frees Multitasking Headroom

One stick occupies the lone expansion slot, raising total system memory to 12 GB when combined with the on-board 4 GB. No heat spreader is fitted, so clearance inside the slim chassis is preserved. Buyers who need more than 12 GB or who own a different laptop family cannot use this part.

Questions about this item

What does the 1600 MHz speed mean once this module is installed in an Asus X555Lb?

The module runs at 1600 MHz with CL11 timing and 1.35 V DDR3L voltage, delivering the rated PC3L 12800 bandwidth inside the notebook.

Which memory standard does the 204-pin SODIMM use and what does it cap in practice?

It uses the DDR3L SO-DIMM standard at 1600 MHz, so the practical ceiling is the PC3L 12800 data rate supported by the laptop's memory controller.

What physical slot and form factor are needed to fit this 8 GB stick in an X554Lj-Xx104D?

A single 204-pin DDR3 SO-DIMM slot is required; the module is unbuffered, non-ECC, 2Rx8 rank and has no heat spreader.
