64GB DDR5 kit for Alienware AMD laptops

This kit supplies 64GB of DDR5 memory in two 32GB SODIMM modules built for the Dell Alienware M16 R1 AMD and M18 R1 AMD. It targets owners of those machines who need more capacity for heavy multitasking or large project files.

Sustained operation at 5200 MT/s CL42

The modules run at 5200 MT/s with CL42 latency and 1.1V voltage under JEDEC standard timings. Unbuffered non-ECC silicon and dual-rank 2Rx8 organisation keep throughput steady during long rendering or compilation sessions without relying on overclock headroom.

262-pin SODIMM form factor, no heat spreader

Each stick uses the standard 262-pin DDR5 SODIMM layout so it seats directly in the factory slots of the compatible Alienware models. The low-profile design without a heat spreader fits tight chassis clearances and simplifies a do-it-yourself upgrade.

Questions about this item

How much heat does the 1.1V DDR5 kit generate under continuous load?

The modules run at the standard JEDEC 1.1V with no heat spreader, so thermal output stays within normal SODIMM limits for sustained use.

What must the laptop already have to accept this 262-pin DDR5 upgrade?

The system needs two free DDR5 SODIMM slots and a memory controller that supports PC5-41600 CL42 2Rx8 modules.

Will the 5200MHz CL42 sticks downclock reliably in an older DDR5 laptop?

Yes — JEDEC-compliant DDR5 memory automatically negotiates the highest speed both the modules and the platform support.
