Compatible 8 GB DDR5 Module

This 8 GB DDR5 UDIMM is built for the Dell Alienware Aurora R15 and runs at 4800 MHz with CL40 latency. It uses a single 1Rx8 rank, operates at 1.10 V, and fits the standard 288-pin desktop slot. The module is non-ECC, unbuffered, and carries no heat spreader.

Suits Aurora R15 Single-Slot Upgrade

The stick suits owners who want a straightforward capacity increase for the Aurora R15 without ECC or registered signalling. Buyers needing registered DIMMs, ECC protection, higher frequencies than 4800 MHz, or capacities beyond 8 GB per slot should look at other options.

Simple UDIMM Installation

Installation follows the normal desktop memory procedure: power down, open the case, align the notch with the 288-pin slot, and press until the latches click. Common issues include seating the module incompletely or mixing speeds that force the system to run slower than expected.

Questions about this item

Does my Alienware Aurora R15 need a DDR5 motherboard to use this 4800 CL40 module?

Yes, the 288-pin DDR5 UDIMM only fits a DDR5 motherboard; the Aurora R15 uses DDR5 so it will accept this stick.

Can I keep my existing 5600 MHz DDR5 sticks and add this 4800 MHz module?

All sticks will run at the lowest speed present, so the 5600 MHz modules will drop to 4800 MHz when this CL40 module is installed.

How do I verify the module is running at 4800 MT/s with CL40 after installation?

Open Task Manager or CPU-Z and confirm the memory speed reads 4800 MT/s and the CAS latency shows 40.
