Compatible Asus A55 Upgrade

This 4 GB DDR3L SODIMM is built for Asus A55, A55A, A55Vd and A55Vm notebooks. It adds a single 1Rx8 module to systems that accept 204-pin memory. Buyers who need ECC, registered DIMMs or capacities beyond 4 GB per slot should look elsewhere.

Low-Voltage Operation

The module runs at 1.35 V with CL11 11-11-11 timings at 1600 MHz. Unbuffered design keeps electrical load light on the notebook's memory controller. No heat spreader is fitted, so airflow in the chassis handles thermal dissipation.

Single-Module Package

The box contains one 4 GB stick identified by part number CM5126412800SOSRL. CMS guarantees compatibility with the listed Asus models. Appearance may differ from product images. Lifetime warranty applies when purchased directly from the manufacturer.

Questions about this item

How do I install the 204-pin DDR3L SODIMM in my Asus A55 notebook, and what step is often missed?

Power off the laptop, remove the battery, open the memory cover, insert the module at an angle until the gold contacts disappear, then press down until both side clips click; the step often missed is re-seating the battery before the first boot.

What maintenance or replacement will this 4GB CL11 module need over its service life?

No scheduled maintenance is required; the module is solid-state with no moving parts, so replacement is only necessary if a memory error appears or you upgrade beyond the 16 GB maximum supported by the two sockets.

What limit appears first when the 1.35 V 1600 MHz stick runs sustained workloads?

The 4 GB capacity is the first bottleneck; once the operating system exhausts physical memory it swaps to storage, which is far slower than the DDR3L-1600 interface.
