8GB DDR4 3200MHz CL22 1.2V 260-pin SODIMM memory upgrade for Alienware M15 R5 and R6 laptops
This OWC module is an 8GB DDR4 3200MHz CL22 SODIMM built for Alienware M15 R5 and R6 laptops. It runs at 1.2V and uses a 260-pin unbuffered non-ECC design. The part targets owners of those specific models who need a straightforward memory increase.
Installation is a standard DIY task: power off the laptop, open the memory door, align the notch on the 260-pin stick, press firmly until the clips lock, then close the cover. The most common issue is seating the module unevenly, which prevents the system from recognising the upgrade.
The stick is organised as 1Rx8, a single-rank 8GB configuration that matches the memory topology expected by the Alienware M15 R5 and R6. Builders whose chassis requires dual-rank modules or a different pin count should look elsewhere.
