Dell Aurora R15 memory upgrade

This 64 GB kit contains two 32 GB DDR5 UDIMMs built for the Dell Alienware Aurora R15. It targets owners who want to expand system memory without replacing the original modules. The unbuffered non-ECC design matches the desktop platform requirements. Installation follows the standard desktop DIMM procedure.

Speed and latency at 4800 MT/s

The modules run at DDR5 4800 (PC5-38400) with a CAS latency of CL40. This specification determines whether the kit matches the memory controller settings used by the Aurora R15. The 2Rx8 organisation and 1.10 V operating voltage are factory configured for this platform. No manual timing adjustment is required.

Thermal and power behaviour

The sticks have no heat spreader and rely on case airflow for cooling. At the rated 1.10 V the power draw per module stays low during typical workloads. Acoustic contribution is negligible because the memory produces no active noise. Adequate chassis ventilation keeps temperatures within normal operating limits.

Questions about this item

What does the DDR5 4800 speed rating mean for actual performance in the Aurora R15?

The modules run at 4800 MT/s with CL40 latency, providing the standard data rate and timing the system expects for stable operation.

What does the PC5-38400 designation tell me about the memory interface?

PC5-38400 confirms a DDR5 4800 MT/s unbuffered UDIMM interface; the system memory controller sets the maximum transfer rate.

Will the 288-pin UDIMM modules fit the Aurora R15 memory slots without a heat spreader?

Yes, they are standard 288-pin DDR5 UDIMMs; the lack of a heat spreader keeps the module height low for the Dell chassis.
