Alienware Aurora R15 Compatible Kit

This 16GB kit contains two 8GB DDR5 UDIMMs validated for the Dell Alienware Aurora R15 desktop. Each module runs at 4800 MT/s with a CL40 latency and 1.10V operating voltage. The 288-pin unbuffered non-ECC design matches the motherboard's memory slots directly. Builders upgrading this specific platform can install the pair without configuration changes.

Tested Modules From Major OEMs

Every stick uses Samsung, Micron or Hynix components screened under load before shipment. The 1Rx8 organisation and PC5-38400 rating reflect the exact timing table the Aurora R15 firmware expects. No heat spreaders are fitted, so the modules sit flush in tight chassis layouts. The kit ships as a matched pair to ensure dual-channel operation from the first boot.

Plain Green PCB For Dense Layouts

The bare circuit board keeps the profile low enough for crowded DIMM banks or large CPU coolers. Gold-contact 288-pin edges resist oxidation during long service intervals. Dell-qualified firmware on the SPD chip allows the system to train at 4800 MT/s automatically. Buyers needing ECC, registered buffers or speeds beyond 4800 MT/s should select a different part number.

Questions about this item

Will the CL40 CAS latency need adjustment or replacement as the system ages?

The CL40 timing is a fixed specification of these DDR5 modules and does not change with age; no maintenance or replacement of the latency setting is required.

What is the first limit reached when the kit runs continuously at DDR5 4800?

The primary limit under sustained load is the 1.10 V operating voltage and CL40 latency, which define the stable speed ceiling for this 16 GB kit.

How much heat and noise do the two 8 GB sticks produce during all-day operation?

Without a heat spreader the bare DDR5 UDIMMs run at the standard 1.1 V, so they generate only modest warmth and zero audible noise in normal use.
