Alienware M18 R2 64 GB DDR5 kit

This kit delivers 64 GB of DDR5 memory in two 32 GB SODIMM modules built for the Dell Alienware M18 R2 laptop. It targets owners who need more capacity for heavy multitasking, large creative projects or virtual machines. The JEDEC-standard 5600 MT/s speed and 1.1 V operation keep the upgrade within the system's native specification.

Sustained workload stability

Rated at CL46 latency and 2Rx8 dual-rank organisation, the modules maintain their 5600 MT/s data rate without relying on overclock profiles. Non-ECC unbuffered design means the memory controller handles error detection, which is standard for consumer laptops. The 1.1 V voltage matches the platform's default power envelope, so thermals stay consistent during long render or compile sessions.

Pre-installation checklist

Verify that your M18 R2 has two free 262-pin SODIMM slots and that the BIOS is updated to the latest Dell release for full 64 GB support. The kit replaces Dell part numbers SNP0X1C3C/32G and AC774046, so confirm those references match your service manual. Buyers who need ECC functionality or registered DIMMs should look elsewhere, as this kit is strictly non-ECC unbuffered.

Questions about this item

How much heat or power does the 1.1V DDR5 5600 kit draw when the Alienware M18 R2 runs under sustained load?

The modules operate at the JEDEC-standard 1.1V, so they draw only the power required for DDR5 5600 CL46 operation without added voltage overhead.

What must the laptop already have for this 262-pin SODIMM kit to work?

The Alienware M18 R2 must provide two free DDR5 SODIMM slots and a BIOS that supports 5600 MT/s non-ECC memory.

Will the 2Rx8 5600 modules run stably alongside the original 4800 MT/s sticks if I keep them?

The memory controller will downclock all installed modules to the lowest common speed, so the 5600 kit will run at 4800 MT/s with the original sticks.
