Targeted notebook upgrade

This 4 GB DDR3 SO-DIMM is built for the Asus A53 notebook series including the A53Z, A53Z-AS61, A53Z-ES61 and A53Z-NB61 models. The module installs in a 204-pin slot and runs at 1.5 V without ECC or buffering. It is sold as a single stick for straightforward capacity increases.

Speed and latency match

The memory operates at DDR3 1333 (PC3 10600) with CL7 timing of 7-7-7. A 2Rx8 rank organisation using 256x8 chips delivers the specified throughput. The supplier also notes a DDR3-1600 (PC3 12800) rating, so the module can run at the higher speed if the platform allows.

For owners of listed Asus A53 models

Buyers with a compatible A53 chassis needing a single 4 GB stick will find this a direct fit. It is not for systems that require ECC, registered modules, a different pin count, or a voltage other than 1.5 V. The notebook supports a maximum of 8 GB across two sockets, so a 64-bit operating system is needed to use the full capacity.

Questions about this item

How does the CL7 latency affect real-world performance in my Asus A53 notebook?

CL7 means the module waits seven clock cycles before delivering data, giving slightly snappier response than the more common CL9 DDR3-1333 sticks when the system runs at its rated 1333 MHz.

What does the PC3-10600 rating actually limit in this laptop?

PC3-10600 caps the memory bus at 1333 MT/s, so the module cannot run faster than the notebook's native DDR3-1333 controller even though the highlights mention 1600 MHz.

Will the 204-pin SODIMM fit the two memory slots in my A53Z?

Yes, the 204-pin DDR3 SO-DIMM form factor matches the two expansion sockets listed for the A53 series, and the module is unbuffered, non-ECC and 1.5 V as required.
