4GB DDR3L SODIMM for Samsung Ultratouch

This 4GB DDR3L 1600MHz SODIMM is built specifically for the Samsung Series 5 Ultratouch NP540U3C laptop. It uses a 204-pin unbuffered, non-ECC layout with CL11 timing at 1.35V. The single module fits the sole memory slot in that chassis.

Verified compatibility removes guesswork

Computer Memory Solutions validates this part against the NP540U3C and NP540U3C-A01UB models so the stick is recognised at POST without manual configuration. The package contains one 4GB module and no additional software or accessories.

Suits owners restoring factory capacity

Buyers who need to replace a failed stick or return the Ultratouch to its original 4GB configuration will find this a direct match. Users wanting more than 12GB total or a second module for dual-channel operation cannot use this laptop because it has only one socket.

Questions about this item

Will the 204-pin DDR3L SODIMM need any firmware updates or re-seating after installation?

No firmware is involved; the module is an unbuffered 1.35 V DDR3L 1600 MHz stick that installs once and runs without further maintenance.

What limit appears first when the Samsung Series 5 Ultratouch NP540U3C runs at full load with this 4 GB stick?

The system maximum is 12 GB across its single socket, so capacity is the first ceiling you reach under sustained use.

How much heat and power does the 1.35 V CL11 module produce during all-day operation?

At 1.35 V the DDR3L part draws less power and runs cooler than standard 1.5 V DDR3, with no heat spreader needed for typical workloads.
