System-specific DDR3L upgrade

This 4 GB module is built for ASUS ROG G20AJ, ROG G20BM and VivoMini UN42 systems. It arrives as a single 204-pin SO-DIMM stick ready to install. The part is new and carries the maker's lifetime warranty when purchased direct.

Low-voltage 1.35 V operation

The stick runs at DDR3L 1600 (PC3L 12800) with CL11 11-11-11 timings. It is unbuffered, non-ECC and uses a 1Rx8 rank layout on major-brand chips. No heat spreader is fitted, keeping the profile slim for tight chassis.

Suits owners of the listed ROG and VivoMini models

Buyers needing more than 4 GB per slot or a dual-channel kit should look elsewhere. Systems outside the three named platforms are not guaranteed compatible, so verify your exact model before ordering.

Questions about this item

What does the 1600 MHz rating mean when this DDR3L module is installed in a compatible system?

The module runs at 1600 MHz with CL11 11-11-11 timings at 1.35 V, delivering PC3L-12800 bandwidth in the supported ROG G20AJ, ROG G20BM or VivoMini UN42.

How does the DDR3L SO-DIMM interface limit performance in these ASUS small-form-factor PCs?

The 204-pin DDR3L SO-DIMM slot caps speed to 1600 MHz and voltage to 1.35 V, so the module cannot exceed PC3L-12800 throughput in the listed systems.

Will this 204-pin stick physically fit the memory slot in a ROG G20AJ, G20BM or VivoMini UN42?

Yes, the 204-pin DDR3L SO-DIMM form factor matches the single SODIMM socket in each of those ASUS models.
