Compatible DDR3 SODIMM for select Asus U47A models

This 4 GB DDR3 1600 module is built to the exact specifications required by the Asus U47A-RS51, U47A BGR4, U47A RGR6 and U47A WO021V notebooks. It uses a 204-pin SO-DIMM form factor and operates at 1.5 V with CL11 latency. The single-rank, unbuffered design matches the original equipment configuration.

Suitable for owners of the listed U47A variants

Buyers with different laptop models, or those requiring ECC or registered memory, should look elsewhere. Systems limited to 4 GB total capacity or those with only one memory slot already occupied by a 4 GB module cannot use this upgrade. Machines with soldered memory and no available slot are also incompatible.

4 GB capacity in a single 204-pin module

The kit contains one 4 GB stick, bringing the compatible U47A models up to their 8 GB maximum when both slots are populated. The 1Rx8 organisation and 11-11-11 timing are fixed characteristics that determine whether the notebook will POST correctly.

Questions about this item

Will this DDR3 1600 CL11 SODIMM run at its rated speed in the second slot of my Asus U47A alongside an existing 1.5 V module?

Yes. Both slots accept DDR3 1600 at 1.5 V, so the new stick will match the voltage and timing of your current memory and operate at 1600 MHz.

How can I verify the module is detected at 1600 MHz with CL11 timings after installation?

Open Task Manager or CPU-Z; the memory tab should show 1600 MHz speed and 11-11-11 latency for the installed 4 GB stick.

Does the single-stick package include any installation tools or thermal pads?

No. The box contains only the 204-pin SODIMM; no screwdriver, thermal pad or extra hardware is supplied.
