CM2048642400SO 16GB DDR4 2400MHz SODIMM

This Computer Memory Solutions module is a 16GB DDR4 2400MHz SODIMM designed for Alienware 17 R3 and R4 notebooks. It operates at 1.2V with CL17 latency and uses a 260-pin unbuffered non-ECC layout. The single stick upgrades one of two available slots in the compatible systems.

Alienware 17 R3 and R4 owners needing 16GB

This module suits Alienware 17 R3 and R4 users adding 16GB to one slot or replacing a failed stick. Buyers wanting a matched pair for dual-channel performance should purchase two identical modules. Systems requiring ECC or registered memory cannot use this unbuffered non-ECC part.

DDR4 2400MHz 260-pin SODIMM specification

The decisive specification is the DDR4 2400MHz 260-pin SODIMM form factor with CL17 timing at 1.2V. The Alienware 17 R3 and R4 support a maximum of 32GB across two sockets, so this 16GB stick fills half that capacity. Verify your notebook model matches the compatible list before ordering.

Questions about this item

Does the 16GB DDR4 2400MHz SODIMM arrive as a single 260-pin stick, or do I need to buy a second module to reach the 32GB maximum?

The package contains one 16GB DDR4 2400MHz CL17 SODIMM. Your Alienware 17 R3 or R4 has two slots supporting up to 32GB total, so a second identical module is required to reach the maximum capacity.

Should I choose the single 16GB CL17 module or look for a matched pair to run in dual-channel mode?

Installing two 16GB sticks enables dual-channel operation on the two available sockets, which increases memory bandwidth. A single 16GB module will run in single-channel mode until a second stick is added.

The listing shows PC4-19200 and CL17 timing; will the memory actually run at 2400MHz once installed in my Alienware 17 R4?

The module is rated for DDR4 2400 (PC4-19200) at CL17 1.2V. The system will operate at the highest speed supported by the CPU and chipset; if the processor or existing memory runs slower, all modules will downclock to that lower speed.
