Alienware DDR5 SODIMM Upgrade

This OWC module provides 16 GB of DDR5 memory at 4800 MT/s in a 262-pin SODIMM form factor. It runs at CL40 latency and 1.1 V without ECC or a heat spreader. The part is validated for specific Alienware laptops including the M15 R7, M16 R1, M17 R5 AMD, M18 R1 AMD and X17 R2.

Builders With Compatible Alienware Notebooks

The upgrade suits owners of the listed Alienware models who want a single-module capacity increase. Systems that require ECC registered memory, a different pin count, or a voltage other than 1.1 V cannot use this module. Buyers needing more than 16 GB per slot should look for higher-density parts.

16 GB Single-Rank DDR5 at 4800 MT/s

The 16 GB 1Rx8 density at DDR5 4800 is the specification that determines fit and performance. This exact capacity and speed combination matches the OEM requirements for the supported Alienware platforms. Confirm your laptop accepts 1Rx8 non-ECC SODIMMs before purchasing.

Questions about this item

Will this DDR5 4800 CL40 1Rx8 SODIMM run with the existing DDR5 modules in my Alienware M16 R1?

The module follows JEDEC DDR5 4800 PC5-38400 CL40 1.1V specifications, so it will operate alongside other JEDEC-standard DDR5 4800 SODIMMs already installed in the M16 R1.

How can I verify the 16 GB DDR5 4800 module is detected at the correct speed after installation?

Enter the system BIOS or UEFI on the Alienware laptop; the memory information screen will list 16 GB capacity, DDR5 technology and 4800 MT/s data rate for the new module.

What comes in the package and do I need any extra parts to install it in an Alienware M15 R7?

The box contains a single 16 GB 262-pin DDR5 SODIMM; no heat spreader, tools or additional cables are included or required for the M15 R7 upgrade.
