Memory Upgrades

Upgrading the Memory (RAM) in Alienware computers enhances performance, especially in tasks requiring substantial processing power (video editing, gaming, or running multiple applications simultaneously). More RAM facilitates smoother multitasking and faster data access, improving the overall user experience.

Before upgrading, consider the maximum RAM capacity, the type and speed of RAM compatible with the system, and your comfort while performing the upgrade. If upgrading memory exceeds your comfort level, seek professional assistance.

Table 1 - Alienware Aurora ACT1250 Owner's Manual lists the supported memory specifications (Alienware Aurora ACT1250 Owner's Manual → Specifications of Alienware Aurora ACT1250 → Memory).

Table 2  - Alienware Area-51 AAT2250 Owner's Manual lists the supported memory specifications (Alienware Area-51 AAT2250 Owner's Manual → Specifications of Alienware Area-51 AAT2250 → Memory).

 

Note: Dell Technologies recommends matched sets of memory from a single vendor to ensure maximum performance.
Note: The listed part numbers in the following tables are those memory cards that have been lab-tested by Dell. Other manufacturers' products have not been tested. Dell cannot validate all possible component combinations.

 

The owner’s manuals do not include Dell part numbers for manufacturers' memory. This article lists them (current as of March 2025):
