Compatible Ultrabook Upgrade

This 4GB DDR3-1600 SO-DIMM is built for the Samsung 5 Ultrabook NP530U3B-A01DE and NP530U3B-A01UK. It uses a 204-pin unbuffered design with CL11 timing at 1.5V. The single module delivers 4GB of system memory for compatible ultrabook models.

Single Slot Installation

The module occupies one 204-pin SO-DIMM socket inside the ultrabook. No heat spreader is fitted, allowing it to sit in thin chassis profiles. Installation requires no additional cables, brackets or software configuration beyond the standard memory slot.

4GB Capacity Limit

The ultrabook supports a maximum of 8GB across its single expansion socket. This 4GB stick provides half that ceiling, leaving room for one more identical module if a second slot were present. Buyers needing more than 8GB total cannot use this platform.

Questions about this item

What is the maximum total memory the Samsung 5 Ultrabook NP530U3B-A27 can accept with this 4GB DDR3-1600 SO-DIMM installed?

The system supports a maximum of 8GB total memory, so adding this 4GB module leaves room for another 4GB stick in the single expansion socket.

Does the CL11 1.5V unbuffered DDR3 module generate noticeable heat or fan noise during continuous operation?

This module has no heat spreader and runs at standard 1.5V; typical ultrabook cooling handles the low power draw without extra fan activity.

Which specific Samsung ultrabook models are confirmed compatible with this 204-pin DDR3-12800 SO-DIMM?

Compatibility is guaranteed for Samsung Series 5 Ultrabook NP530U3B-A01DE and NP530U3B-A01UK as listed by the manufacturer.
