Capacity and Compatibility

This is a 4GB DDR3 SO-DIMM built for ASUS A53 notebooks including the A53SD, A53SJ, A53SM and A53TA-SX080V models. It installs in a 204-pin slot and runs at 1333MHz with CL7 timing at 1.5V.

Who It Suits

Owners of the listed A53 laptops who need a single 4GB module to fill one of the two memory sockets will find guaranteed compatibility. Buyers who want more storage capacity than 4GB or who need ECC or registered memory should look at something else.

Deciding Specification

The module operates at DDR3 1333 (PC3-10600) with a CAS latency of 7 and 2Rx8 organisation. Matching this speed and timing is the single specification that decides whether this is the right part for your notebook.

Questions about this item

Does this 204-pin DDR3 SO-DIMM fit the ASUS A53 notebook series?

Yes, it is validated for ASUS A53SD, A53SJ, A53SM and A53TA-SX080V models with two SO-DIMM slots supporting up to 8 GB total.

What is the correct way to seat this 1.5 V unbuffered module, and what step do people often miss?

Power off, remove the battery, insert the stick at a 30-degree angle until the gold contacts disappear, then press down until both side clips click — skipping the battery removal risks a short.

When should this CL7 2Rx8 stick be replaced or upgraded?

Replace if memory errors appear in diagnostics; upgrade by adding a second 4 GB DDR3 1333 MHz SO-DIMM to reach the 8 GB maximum supported by the A53 platform.
