CMS 4GB DDR3 SO-DIMM for Asus X54 Series

This 4GB DDR3 SO-DIMM module runs at 1333MHz with CL7 timing and 1.5V voltage. It uses a 204-pin unbuffered non-ECC design with 2Rx8 rank organisation. The stick is validated for Asus and Mobile X54 series laptops including X54C, X54H, X54Hr and X54HY models.

Ideal for single-slot X54 upgrades

Owners of compatible Asus X54 notebooks needing a direct memory replacement will find this module fits the single socket. Buyers whose systems require ECC registered memory or operate on a different DDR generation should look elsewhere. The 4GB capacity matches the documented maximum for these platforms.

1333MHz DDR3 speed confirms fit

The PC3 10600 rating at 1333MHz is the decisive specification that determines compatibility with the X54 series chipset. Systems limited to this memory speed will recognise the full 4GB when running a 64-bit operating system.

Questions about this item

My laptop only has one SODIMM slot — will this single 4 GB stick fill it completely?

Yes, the Asus X54 series has one 204-pin DDR3 slot and a 4 GB maximum, so this module occupies the only slot.

If I keep the original 2 GB module in a second slot, will the system run both at 1333 MHz?

The X54 series provides only one memory socket, so a second module cannot be installed alongside this one.

How can I verify the module is running at the rated 1333 MHz after installation?

Open Task Manager’s Performance tab or run CPU-Z; both will show the memory operating at 1333 MHz (PC3-10600) with CL7 timings.
