Alienware 17 R3 R4 DDR4 SO-DIMM

This 4 GB module is built for Alienware 17 R3 and R4 notebooks that require DDR4 SO-DIMM memory. It installs in a 260-pin slot and runs at 1.2 V without ECC or buffering. The single-stick kit suits owners who need a direct replacement or a first module in an empty slot.

Sustained-load behaviour

Rated at DDR4 2400 with CL17 17-17-17 timings, the stick maintains its specified frequency and latency during extended sessions. Unbuffered 2Rx8 organisation lets the memory controller address both ranks without added delay. The major-brand chipset supports stable operation at the rated PC4 19200 bandwidth over long periods.

Capacity limit

Each SO-DIMM socket accepts up to 32 GB and the platform provides two sockets for a 64 GB maximum. A 64-bit operating system is required to address more than 4 GB of total memory. Buyers who want more storage or who need a second card should look elsewhere.

Preguntas sobre este artículo

How much heat does the 1.2V DDR4 2400 module produce when running all day?

At 1.2V the CM512642400SO draws minimal power and runs cool without a heat spreader, so temperatures stay low even under continuous load.

What does my Alienware 17 R3 or R4 need for this 260-pin SODIMM to work?

An open DDR4 SO-DIMM slot and a 64-bit operating system are all that is required; the laptop's two sockets accept this 4GB stick directly.

Will this 4GB CL17 stick slow down the faster memory already in my Alienware 17?

All installed modules run at the speed of the slowest one, so adding this DDR4 2400 CL17 module will match the system to its timing if the existing RAM is faster.
