Alienware M18 R2 DDR5 Upgrade

This 16GB DDR5 SODIMM is built specifically for the Dell Alienware M18 R2 laptop. It targets owners who need a single-module memory increase for multitasking or larger workloads. The module follows JEDEC-standard timings at 5600MHz CL46 and runs at 1.1V without a heat spreader.

SODIMM Slot Installation Notes

Installation is a straightforward DIY task on most Alienware M18 R2 units. The 262-pin keying prevents backward insertion, so alignment is the only mechanical step. Common issues arise when the slot is not fully seated or when the system BIOS has not been updated to support the full 5600MHz speed.

16GB 1Rx8 DDR5 5600 CL46 Spec

The decisive specification is the 1Rx8 organisation at DDR5 5600 CL46 1.1V. This rank and latency combination must match the laptop’s memory controller requirements; a different rank count or CAS latency will cause instability or prevent boot.

Questions about this item

How can I confirm the 5600MHz CL46 DDR5 SODIMM is running at its rated speed after installing it in my Alienware M18 R2?

Enter the system BIOS or use a tool such as CPU-Z to verify the memory frequency shows 5600MHz and the CAS latency reads CL46.

What does the box contain and is anything else needed to complete the upgrade?

The package includes one 16GB 262-pin DDR5 5600 CL46 1.1V Non-ECC SODIMM module; no additional parts or cables are required for installation.

Which capacity should I choose if I want a single module that matches the factory Dell part SNPW1KKYC/16G?

Select the 16GB version, which is a direct replacement for the Dell SNPW1KKYC/16G module and fits one SODIMM slot in the Alienware M18 R2.
