Targeted upgrade for Asus Pro Ultrabook BU400A

This 8 GB DDR3L SO-DIMM is built specifically for the Asus/Asmobile Pro Ultrabook BU400A. It arrives as a single 204-pin module rated at 1600 MHz with CL11 timings and 1.35 V operation. The kit adds memory to the system's single expansion socket.

Capacity and headroom

The laptop supports a maximum of 12 GB total memory across its one slot. Installing this 8 GB stick leaves 4 GB of headroom if the original module remains, or fills the slot completely when replacing a smaller unit. The unbuffered, non-ECC design matches the platform's requirements.

Build fit and practical notes

The module uses major-brand chips in a standard 204-pin DDR3L form factor without a heat spreader. It requires a system that accepts 1.35 V DDR3L SO-DIMMs and has a free 204-pin slot. Buyers needing more than 12 GB total capacity or dual-channel configurations must choose a different platform.

Questions about this item

Will this 204-pin DDR3L 1600 CL11 1.35V module run alongside existing DDR3 1.5V memory in the BU400A ultrabook?

The BU400A has a single SO-DIMM socket and supports up to 12 GB total, so the 8 GB stick replaces any original module rather than running alongside it.

How can I confirm the stick is recognised at 1600 MHz with CL11 11-11-11 timings after installation?

Open Task Manager or CPU-Z and check that the memory reports 1600 MHz, DDR3L, 1.35 V, CL11 and 2Rx8 organisation.

Does the package contain only the 8 GB SO-DIMM or are tools or adapters included?

The box contains one 8 GB 204-pin DDR3L SO-DIMM; no tools, adapters or extra parts are supplied.
