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.

Perguntas sobre este artigo

How much voltage does the 4800MHz DDR5 SODIMM draw under sustained load?

The module operates at 1.1V, the standard JEDEC voltage for DDR5 4800 SODIMMs.

Does the 262-pin DDR5 4800 CL40 stick produce noticeable heat or fan noise during all-day use?

It has no heat spreader and runs at the low 1.1V JEDEC voltage, so thermal output stays minimal in typical laptop chassis.

Which Alienware models must I already own for this 8GB 1Rx16 SODIMM to work?

Compatible systems are Alienware M15 R7, M16 R1, M17 R5 AMD, M18 R1 AMD and X17 R2.
