4GB DDR3L SO-DIMM for Asus K55

This 4 GB DDR3L module runs at 1600 MHz with CL11 timing at 1.35 V. It uses a 204-pin unbuffered layout and a single 1Rx8 rank built from major-brand chips. The stick is designed as a direct memory upgrade for Asus K55Dr, K55N and K55Vm notebooks.

Suits owners of listed K55 models.

Buyers with an Asus K55Dr, K55N or K55Vm can install this module without compatibility guesswork. Systems that require registered or ECC memory, a different pin count, a higher voltage than 1.35 V, or more than 16 GB total capacity cannot use this stick. The kit contains only one module, so a dual-channel configuration needs a second matching stick.

Single stick enables incremental upgrades

The package includes one 4 GB SO-DIMM and nothing else. No heat spreader, driver disc or software utility is bundled. Because the notebook has two sockets and supports up to 16 GB, adding this module increases usable memory while leaving the second slot free for future expansion.

Questions about this item

My ASUS K55 notebook has two DDR3L slots — can I install this 204-pin 4 GB module alongside the existing stick?

Yes. The K55 series uses two SODIMM sockets supporting up to 16 GB total, so adding this 1Rx8 1.35 V module works with the original memory.

Will the CL11 1600 MHz timing of this module force my older DDR3L RAM to run slower?

The memory controller will match the slowest installed stick. If the original module is also DDR3L 1600 CL11, both run at rated speed; otherwise they drop to the lower common timing.

How can I confirm the new 4 GB stick is recognised at 1600 MHz after installation?

Open Task Manager → Performance → Memory or run CPU-Z; the SPD tab should show 1600 MHz, CL11-11-11 and 1.35 V for the new module.
