32GB DDR4 kit for Alienware Aurora R6–R9

This 32GB kit contains two 16GB DDR4 2666 CL19 modules built for Alienware Aurora R6, R7, R8 and R9 desktops. It runs at 1.2V without ECC or buffering, using 288-pin DIMM form factor. Buyers needing ECC, registered DIMMs or speeds beyond 2666 MHz should look elsewhere.

Straightforward two-slot upgrade

Installation follows standard DIMM procedure: power off, open the chassis, align the notch and press until the latches click. The kit occupies two of the four available slots, leaving room for further expansion. No heat spreader is fitted, so clearance is minimal, but tall CPU coolers could still interfere with the nearest slot.

DDR4 2666 limits capacity to 64GB total

The platform supports a maximum of 64GB across four sockets, so this 32GB kit uses half the headroom. Speed is fixed at 2666 MT/s (PC4-21300) with CL19 timings; faster or lower-latency modules will downclock to this rate. Non-ECC unbuffered operation is required — ECC or registered sticks are not compatible.

Questions about this item

How can I confirm the kit is running at DDR4 2666 CL19 after installation?

Open Task Manager or CPU-Z and verify the memory tab shows 2666 MT/s with 19-19-19 timings at 1.2 V.

What comes in the box and is anything else required?

The package contains two 16 GB 288-pin DDR4 DIMMs; no extra cables or brackets are needed for the supported Aurora desktops.

Which capacity should I choose if my Aurora R7 has four slots and supports up to 64 GB?

This 32 GB (2 x 16 GB) kit fills half the slots, leaving room to add another identical kit later for the full 64 GB maximum.
