About this guide
Alienware used the Area-51m name on two importantly different laptops. The 2019 Area-51m (R1) has 4 DDR4 SO-DIMM slots and Dell specifies up to 64GB using 4 16GB modules at 2400 MT/s; it also lists 2666 and Dell-supplied 2933 XMP configurations. The Area-51m R2 has only two SO-DIMM slots and supports up to 64GB as 2x32GB DDR4-2933, while Dell says third-party XMP modules are unsupported. Buy 260-pin DDR4 SO-DIMMs, not full-size desktop DIMMs. The compatible retail kits below use standard 1.2V profiles and may run below their 3200 label in either generation; do not assume a third-party 3200 XMP kit will deliver 3200 MT/s.

Buying tips
- Identify R1 or R2 in Dell SupportAssist or the service tag before buying: R1 has 4 SO-DIMM slots; R2 has two.
- For R1’s documented 64GB layout, use 4 identical 16GB SO-DIMMs; for R2, use a matched 2x32GB kit.
- After fitting memory, check BIOS for total capacity and operating speed, then run a memory test before relying on the laptop.
