OWC 8GB DDR5 4800 CL40 1Rx16 SODIMM memory upgrade

Single-module 8 GB DDR5 upgrade

This OWC SODIMM adds 8 GB of DDR5 memory to compatible Alienware laptops. It targets owners of the M15 R7, M16 R1, M17 R5 AMD, M18 R1 AMD or X17 R2 who need more capacity for multitasking. The module is a non-ECC, unbuffered 262-pin stick rated at 4800 MT/s with CL40 latency.

Fits a single SO-DIMM slot at 1.1 V

Installation uses one available SO-DIMM socket in the notebook and draws 1.1 V, matching the platform's standard DDR5 voltage. No heat spreader is fitted, so the module sits flush in tight laptop chassis. The upgrade frees the existing slot configuration for a second module if the system supports dual-channel operation.

Steady JEDEC-rated throughput

The memory runs at its JEDEC 4800 speed continuously without overclocking headroom or XMP profiles. Sustained workloads such as large file edits or virtual machines see consistent bandwidth at CL40 timings. Buyers who need ECC error correction or registered buffering should look elsewhere, as this stick is strictly non-ECC unbuffered.
