Compatible Aurora R13 R15 Upgrade

This single 8GB DDR5 module is built for Alienware Aurora R13 and R15 desktops. It installs in a standard 288-pin UDIMM slot and runs at the JEDEC 4800 speed grade. The non-ECC unbuffered design matches the factory memory specification for these systems.

Sustained Load Behaviour

Operating at 1.1V with CL40 latency, the module maintains its rated DDR5 4800 throughput during extended workloads. The 1Rx16 organisation delivers consistent bandwidth for multitasking and large-file handling without thermal throttling. JEDEC compliance ensures stable operation at the specified voltage.

Pre-Installation Checks

Verify your Aurora model is R13 or R15 before ordering, as compatibility is limited to those platforms. Confirm an empty 288-pin DDR5 slot is available for the upgrade. Ensure the system BIOS is current to support the 4800 MT/s data rate.

Questions about this item

How much power does this 1.1V DDR5 module draw when the Aurora runs all day?

The module operates at 1.1V, the standard JEDEC voltage for DDR5 4800, so power draw stays within the Aurora R13 and R15 memory-slot limits during continuous use.

What must my Alienware Aurora already have for this 288-pin UDIMM to work?

Your Aurora R13 or R15 needs a free 288-pin DDR5 UDIMM slot and a BIOS that supports JEDEC DDR5 4800 CL40 1Rx16 modules.

Will this CL40 stick run stably alongside the original memory in my Aurora R13?

Yes, it is tested to meet OEM specs for Aurora R13 and R15, so it will run at the system's default DDR5 4800 speed alongside factory-installed modules.
