ASUS Laptop SODIMM Upgrade

This 8 GB DDR4 module is built for ASUS laptops and all-in-one PCs that accept 260-pin SODIMMs. It targets owners who need a straightforward capacity increase without changing voltage or form factor.

Unbuffered Non-ECC 2Rx8 Build

The stick uses major-brand Samsung, Micron or Hynix chips in a 2Rx8 layout and runs at the standard 1.2 V. No heat spreader is fitted, so it sits flush in tight SODIMM slots and adds no extra height.

Single-Module Pack

The box contains one 8 GB SODIMM rated at DDR4 2666 CL19 (PC4-21300). No extra cables, brackets or software are included, so the upgrade is limited to the memory slot itself.

Questions about this item

What does the DDR4 2666 PC4-21300 interface cap the module at in practice?

The module runs at 2666 MT/s with CL19 latency and 1.20 V, matching the PC4-21300 bandwidth ceiling for DDR4 SODIMMs.

What physical slot and keying does this 260-pin SODIMM need to fit?

It requires a standard DDR4 260-pin SODIMM slot with the DDR4 key notch; the low-profile stick has no heat spreader so it clears tight laptop and AIO chassis.

How is the module installed and which step do people often get wrong?

Power off, open the memory door, align the notch, insert at an angle, then press down until both side clips click — skipping the full click leaves the stick loose and the system won't boot.
