Dell Alienware Aurora R15 kit

This 128GB kit contains four 32GB DDR5 4800 modules built for the Dell Alienware Aurora R15. The PC5-38400 unbuffered UDIMMs run at 1.1V with CL40 latency and a 2Rx8 rank layout. They install in the standard 288-pin desktop slots and carry no heat spreaders.

Suited for full-capacity Aurora R15 upgrades

Owners who need the maximum supported memory for heavy multitasking, content creation or virtualisation will use all four slots. Builders who only want a modest boost, who prefer lower-latency sticks or who need ECC protection should look at something else.

Capacity and speed lock-in

The decisive specification is the 128GB total at DDR5 4800 (PC5-38400) in a 4×32GB configuration; the Aurora R15 must accept this exact density, voltage and form factor for the kit to work.

Questions about this item

Will these 288-pin DDR5 UDIMM modules fit the four DIMM slots on my Alienware Aurora R15 motherboard?

Yes — the kit contains four 32 GB modules built to the standard 288-pin DDR5 UDIMM form factor that the Aurora R15 uses.

What is the correct seating order for the four modules when I install them?

Populate all four slots; the motherboard manual shows the exact slot sequence for a four-stick population.

Do the modules need any active cooling or thermal-pad replacement over time?

No — the sticks ship without a heat spreader and run at 1.1 V, so no extra cooling or pad maintenance is required.
